Introduction

2.1

What is ProTool?

Configuring graphics displays ProTool is an innovative configuration software package for the whole SIMATIC HMI family. You use the same configuration software to configure all the devices in the family. Regardless of the device for which you are creating your project, ProTool always presents you with the same, familiar user interface.

Example of the structure: ProTool

PC

PLC OP37

Example: a PC for configuration and an OP37 as the operating unit:

ProTool is easy to use ProTool is a Windows application for Windows® 95, Windows ® 98 and Windows® NT. The fully graphical user interface allows you to create object-oriented, symbolbased projects easily by mouse click. No special programming knowledge is required. You can continue to use the Windows applications with which you are familiar to transfer graphics to your project, for example.

ProTool is versatile The editors provided in ProTool can be called simultaneously. You can also open different projects, even those of different devices, simultaneously and transfer data via the clipboard from one project to another.

2-2

ProTool User’s Guide Release 12/99

Introduction

ProTool can also be integrated in the SIMATIC STEP 7 configuration software, thus allowing you to select STEP 7 symbols and data blocks as tags in ProTool. This not only saves you time and money but also eliminates the possibility of errors made when entering the same data several times. You will find more information on configuring ProTool with SIMATIC STEP 7 at Configuring with ProTool integrated in STEP 7 (Chapter 3.3.1).

Offline configuration With ProTool you create and edit your projects offline. The device need not yet be available at this time. The configuration computer displays the configured process data as it will subsequently be displayed on the device. On completion of configuration you can download the executable project file from the configuration computer to the device.

•

You can select STEP 7 symbols and data blocks from the S7 symbol table as tags. The data type and address are entered automatically.

•

ProTool lists all the PLCs in your STEP 7 project and, once a PLC has been selected, determines the associated address parameters.

•

In STEP 7 you can configure ALARM_S messages and output them to the operating unit.

ProTool User’s Guide Release 12/99

Installing and configuring ProTool

Selecting languages The installation program prompts you for the options and languages to be installed. If you wish to install several languages simultaneously, select the User defined option when you are installing. You can then change the ProTool language later without having to reinstall ProTool by opening Start Menu→ Simatic → ProTool CS → ProTool Setup. During installation you specify the language that you want to be active after installation.

Installing ProTool from a CD-ROM To install ProTool, proceed as follows: 1. Insert the installation CD in the CD-ROM drive. If the autorun function for your CD-ROM drive is activated, the browser starts automatically when you insert the CD. Alternatively, select the CD-ROM drive in Explorer, and double-click install.exe to start the installation program. 2. Select the installation language you want at Language. 3. Select Installation and install ProTool/Pro CS first, followed by ProTool/Pro RT. When installing, follow the instructions on the screen. Note: Make sure when you are installing ProTool/Pro RT that you do not use blanks in the path name if you choose to install ProTool/Pro RT under a different path name from the one proposed. 4. If you have STEP 7 programming software as of V4 on your computer, you can also install ProTool integrated in STEP 7. ProTool checks in Setup whether STEP 7 is installed on your system. If STEP 7 is has been installed, you can choose whether ProTool should be installed in Integrated or Stand-alone mode. 5. Install the license when prompted to do so. If you do not have a license when you are installing ProTool/Pro Runtime, you can install it later. The procedure for this is described in commissioning instructions, software protection.

ProTool and Asian Windows systems

Windows system language ProTool also supports the Asian languages Chinese (PRC), Chinese (Taiwan) and Korean as configuration languages. To create projects in these languages, you need a Windows system in the language concerned. This Asian Windows system can be installed either as a stand-alone operating system or as an additional operating system over and above your present system.

Tip A Chinese or Korean Windows system is installed in a manner similar to any other language. In the event of uncertainties with regard to the requisite settings in Setup, you can clarify them by installing a Windows system in a different language beforehand.

ProTool user interface language You can then install ProTool itself under the Asian Windows system in the customary manner in the user interface languages English, German, French, Italian or Spanish.

Example: installing Chinese Windows 95 as a second operating system You can install a Chinese Windows 95 system on your computer alongside a Windows 95 system in a different language. You can then switch between two Windows languages.

Requirements: The following requirements have to be met if you wish to operate ProTool under a second Windows 95 system: •

ProTool is installed under your present Windows 95 as stand-alone application or it has been integrated with STEP7.

•

To install a second Windows 95 system, you require a second hard disk or partition, since conflicts may otherwise occur when the Programs directory is accessed.

•

The startup drive has to be formatted in a FAT format that is supported by both Windows 95 systems.

Procedure: To use ProTool under Chinese Windows 95 as a second operating system, perform the following steps: 1. Prior to installation of the second Windows system, save the following five system files to the directory called C:\Winboot\Old: − autoexec.bat − config.sys − msdos.sys − io.sys − command.com The files will be required upon changing the operating system. 2. Before you proceed to install Chinese Windows, pay attention to the following notes so that existing authorization files of STEP7, for example, are not destroyed: − Remember to transfer the authorization back to your authorization floppy disk before you format, compress or restore your hard-disk drive or before you install a new operating system. − A cluster identified as "defective" occurs on the destination drive with the authorization. Do not attempt to restore it.

Installing and configuring ProTool

3. Install Chinese Windows 95 on a separate partition (e.g. D:\). To do this, you must exit from Windows and restart in DOS mode. 4. All programs that you want to run under Chinese Windows 95 - such as ProTool or STEP7 - have to be installed under it once more owing to the update of registry entries and of the system files in the Chinese Windows system. However, you should you the same directory for installation in order to keep the memory requirement low. 5. After you have installed Chinese Windows 95 and the application programs, save the five files of the Chinese Windows version mentioned above to the C:\Winboot\Chs directory. 6. If you then install another application program in one of the operating system, you have to save the autoexec.bat and config.sys files concerned yet, since they may be modified as a result of installation.

Switching between Windows 95 versions: To switch between the two Windows versions, copy the five saved files for the language you want to the startup drive C:\ before exiting from the operating system. Windows 95 then has to be restarted. To facilitate this task, various batch and PIF files are supplied with ProTool in the ProTool\Utility subdirectory: •

old.bat

•

old.pif Link with batch for placing on the desktop

•

chs.bat

Batch for switching to Chinese

•

chs.pif

Link with batch for placing on the desktop

Batch for switching to the Windows you installed first

You should similarly copy these files to the C:\Winboot\Old and C:\Winboot\Chs directories so that the ultimate file structure is as follows: C:\Winboot\Old old.bat old.pif autoexec.bat

Configuring ProTool

3.3.1

Configuring with ProTool integrated in STEP 7

Requirements If the PLC you are using is a SIMATIC S7 and you have installed STEP 7 configuration software on your system, you can integrate ProTool in STEP 7.

Advantages of STEP 7 integration As you are using the same database as STEP 7, you have the following advantages: •

You assign your symbolic name once only and can then use it everywhere. Note If you use an instance DB in the STEP 7 program, the corresponding instance FB must also be defined in the symbol table in STEP 7. If this is not the case, this DB is not offered for selection in ProTool.

3-10

•

When you configure variables and area pointers, you access the STEP 7 symbol table. Changes to the symbol table in STEP 7 are updated in ProTool (refer to the figure at Properties of tags (Chapter 5.4.2)).

•

When the project is compiled, the data is synchronized.

•

In STEP 7 you can configure ALARM_S messages and output them to the operating unit.

•

The communication parameters of the PLC are transferred directly to your project.

Integrating ProTool projects Projects created in ProTool on a stand-alone basis cannot be called directly using SIMATIC Manager. To include projects like this in a STEP 7 project, they have to be integrated. To do this, choose the File → Integrate menu command in ProTool. In the STEP 7 configuration, give the ProTool project a different name to the original project. Note Conversely, projects created with ProTool on an integrated basis must on no account be edited with ProTool on a stand-alone basis. If they were, the connection to the STEP 7 symbol table would be lost.

Fundamental considerations when creating a project

Objective To operate and monitor a machine or process. To do this, you map the machine or process on the operating unit as accurately as is necessary.

System configuration Communication takes place between the operating unit and the machine or process by means of tags via the PLC. The value of a tag is written to a memory area (address) on the PLC, from where it is read by the operating unit. The following diagram provides an overview of the fundamental structure:

Operating unit

Printer

Communication by means of tags

Machine, process

A typical structure

Before you begin If you are creating a project for the first time, note the following recommendations: • Use the standard screens from the standard projects. When creating a new project, you can select a standard project for your system (operating unit and PLC) from the project assistant. • Under ...\ProTool\Samples you will also find the sample project "Quickmix", which is implemented for various operating units and PLCs. • Consider also whether you can use parts of existing projects. Message texts or graphics, for example, are suitable for this. • In the case of operating units from a single device family, it is also possible to copy entire project sections via the clipboard. Note The prerequisite for successful copying between projects is that the system limits of the operating unit for which you want to use the copied sections must not be exceeded.

4.2

What does a ProTool project consist of? When you open a new or an existing project, the project window opens.

What objects are there in ProTool? In the project window, the object types you can configure appear on the left, and the objects themselves appear on the right. The objects that you can configure depend on the type of the operating unit. The various objects are linked directly in ProTool with the tool required to edit them.

What is displayed in the project window? The project data of a ProTool project is stored in the form of objects. The objects in a project are arranged in a tree structure. The Project window displays object types that belong to the project and that you can configure for the selected operating unit. The project window is comparable with Windows® Explorer. The object types contain objects with properties that can be set. The project window is structured as follows: • The title bar contains the project name. • The left half of the screen displays object types that you can configure, and the right half of the screen displays the objects contained in them.

Example of a project window with tags

Note If you maximize the project window, tabs are displayed for the open windows along the bottom border to enable you to change easily from one window to another.

4.3

Steps to be taken when creating a project To create a project, proceed as follows: 1. Create a new project (File → New or File → Open) Choose File → New to create a new project. The project assistant guides you through a number of selection dialogs. 2. Select a PLC Select a driver for your PLC. Only those drivers with which the operating unit can be run are displayed. 3. Use a standard project Select a standard project in order to use it as a basis. 4. The project assistant allows you to enter information on the project in the summary. If you click the Create button, the project window opens. 5. Define communication areas (System → Area Pointers). To enable the operating unit and PLC to communicate with each other, you have to define communication areas (Setting up area pointers (Chapter 4.4)) that are to be used by them both. 6. Create a project This is the most involved part of the work. You can approach it in one of two ways: Either you create all the individual parts first and then link them to form a meaningful structure (the bottom → up approach), or you begin by designing a structure and then fill it with the individual elements (the top → down approach). To do this, you basically have to perform the following steps: − Create the user interface with display and controls. − Configure tags in order to enable data interchange with the PLC. − Configure messages in order to obtain information on the state of the machine or process. − Split the display on the operating unit (not on devices with a text-based display). In addition, you can configure additional objects, such as recipes, depending on the operating unit.

Setting up area pointers

What are area pointers for? A defined address area on the PLC for data interchange with the operating unit is addressed by means of an area pointer. Choose System → Area Pointers to set up area pointers.

What area pointers are available? The number of area pointers available varies depending on the selected operating unit. For information on how large the area pointers should be when you create them, and the structure they have to have, refer to the Communication User’s Manual. The overview below lists the various area pointers and what they are used for. The order in which they are listed corresponds to that in ProTool. Area pointer

Explanation

Interface area

The interface area is the interface between the PLC program and the operating unit. It contains data and pointers to areas required for data interchange between the PLC and the operating unit.

User version

The user version identifies the version of the project. A version check is performed on the PLC by means of this area pointer.

Screen number

The operating unit stores information on the current screen in this data area. You can evaluate this information in the PLC program in order to call another screen, for example.

Data mailbox

The data mailbox is a data area on the PLC. It is used as intermediate storage to download data records from the operating unit to the PLC. The data mailbox contains only the values of the tag. The addresses are not transferred.

Event messages

You can configure an event message for each bit in this data area. The bits are assigned to the message numbers in ascending order. As soon as the PLC sets a bit in this data area, the operating unit recognizes that the assigned event message has "arrived". Conversely, the operating unit interprets the message as "gone" after the bit is reset in the PLC.

ProTool User’s Guide Release 12/99

Creating projects

Area pointer

Explanation

Alarm messages

You can configure an alarm message for each bit in this data area. The bits are assigned to the message numbers in ascending order. As soon as the PLC sets a bit in this data area, the operating unit recognizes that the assigned alarm message has "arrived". Conversely, the operating unit interprets the message as "gone" after the bit is reset in the PLC.

4-6

PLC acknowledgement

The PLC uses this area to indicate to the operating unit which alarm messages have been acknowledged by the PLC.

OP acknowledgement

The operating unit uses this area pointer to indicate to the PLC which alarm messages have been acknowledged on the operating unit.

System keyboard

The operating unit transfers keystrokes of the system keys via this data area. You can evaluate this information in the PLC program in order to indicate incorrect operation by means of a message, for example.

Function keyboard

The operating unit transfers keystrokes of the function keys via this data area. You can evaluate this information in the PLC program in order to indicate incorrect operation by means of a message, for example.

LED assignment

The PLC can use this area pointer to drive the lightemitting diodes on the function keys of the operating unit.

Trend request

The PLC can use this area pointer to determine which trend is currently being displayed on the operating unit.

Trend transfer area 1

This data area is used to trigger trends. As soon as the PLC program sets the bit assigned to the trend and the trend communication bit in the trend transfer area, the operating unit detects the trigger and, depending on the configuration, reads out either a value or the entire buffer.

Trend transfer area 2

This data area is required when you configure trends with a switch buffer. The data area is structured in the same way as the trend transfer 1 data area.

Subdividing the display on the operating unit

Subdividing the display into several areas The operating unit’s display area can be split into different areas. These are the areas for displaying screens and messages and for the soft keys (OP) and buttons (TP). Icons can be positioned on the edge of the screen for the soft keys.

Where do you set the areas? Choose System → Screen/Keys to set the areas. The settings made here apply to the whole project, so set the areas before you begin configuration. The figure below shows an example of how the OP27’s display can be subdivided:

Fixed window Event message window

Basic area

Message indicator

Function key assignment Typical OP27 display subdivision

Basic area The basic area is the lowest level and covers the whole screen. All the other areas are superimposed on parts of the basic area. The position and size of the basic area cannot be changed. Screens are configured in the basic area. The contents of the basic area thus change depending on the screen that is called.

4-8

ProTool User’s Guide Release 12/99

Creating projects

Fixed window A fixed window is a window that is always displayed. It uses up part of the basic area. The fixed window can be switched on or off under Screen/Keys. If it is switched on, it is displayed during screen configuration and thus reduces the size of the area available for screens. The size of the fixed window can be changed, but its position is always the same at the top of the screen. The fixed window is configured with the Screens editor.

Alarm message window The alarm message window is the window in which alarm messages appear. The window only opens when there is an alarm message. When you acknowledge the alarm message, the window closes again. The display of alarm messages cannot be switched off. Either an alarm message window or a message line must be configured. The position and size of the alarm message window cannot be configured.

Event message window The event message window is the window in which event messages appear. The window is only displayed when called. You can switch the event message window on or off by choosing System → Screen/Keys. The height of the window can be set to one or two lines, depending on the device type. The position can also be changed.

Message line The message line is the area in which alarm and event messages are displayed. In the case of touch panels, only event messages are displayed in the message line. You can switch the message line on or off by choosing System → Screen/Keys. The height of the message line can be set to one or two lines, depending on the device type. The position can also be changed.

Message indicator The message indicator is a symbol indicating alarm messages that are still applicable on the operating unit. You can switch the message indicator on or off by choosing System → Screen/Keys. You cannot change the size, but you can the position. The message indicator can be used with touch panels.

Dynamic position (OP35/37 only) The message and help text windows are positioned dynamically as a function of the cursor position so as not to cover up input fields that are currently being edited. You can switch this function on or off by choosing System → Screen/Keys.

Icons (OP only) Icons can be placed on the display for soft keys (keys assigned functions locally). This is only possible for the FX keys arranged around the display. To find out how to assign keys globally or locally, refer to What are function keys? (Chapter 5.3.5)

Configuration notes for the touch panels

Screen partitioning basics Before you start setting touch panel controls, you should give a thought to the basic partitioning of a screen. Give consideration to where messages and input windows will be opened in order to prevent unintentional overlapping of buttons and input fields. The figure shows an example of screen partitioning on the TP37.

Touch grid Enable the display of the touch grid with the illustrated symbol or by choosing View → Interface from the menu. To do this, activate the Display touch grid check box. The touch grid designates the smallest possible spacing between two points which the touch panel detects as single dots when its screen is touched. The display grid makes it easier for you to position the controls. You can place controls anywhere within the touch grid. The grid is not visible on the operating unit.

Invisible buttons If you use invisible buttons in your project, you should enable the display of invisible buttons while configuring. To do this, select the symbol illustrated or choose View → Interface from the menu. Activate the Display invisible buttons check box in the open dialog box.

Global buttons Buttons and their assigned functions are available only locally on the screen concerned. Therefore, position buttons which you want to be available globally in every operating situation in the fixed window of the TP.

Overlapping controls Mutual overlapping of controls is not allowed. Since overlapping controls may result in undefined operating states, they are reported as errors when the project file is compiled.

Copying objects: Between projects and within a project

Principle You can cut or copy selected parts of your project and paste them via the clipboard. For example you can copy text and fields from the alarm message editor to the event message editor, or graphic elements from one screen to another. The prerequisite for successful copying between projects is that the system limits of the destination project must not be exceeded.

Preparations for new projects Before starting to copy objects from an existing project, you should without fail carry out the following global settings in the new project. This will ensure that no loss of data occurs during copying due to different settings. •

Under the heading System → Screen / Keys make the subdivision of the screen display the same as in the source project.

•

Make the name and driver of the PLC the same as in the source project.

Procedures There are two ways of pasting objects from the clipboard to the destination project: •

Menu command Edit → Paste The object is pasted from the clipboard to the destination project. If there is already an object of the same name in the destination project, the object is pasted under a new name.

•

Menu command Edit → Paste Special Only objects that are different are pasted. If there is already an identical object of the same name in the destination project, this is used. If there is an object that has the same name but is not identical, the object from the clipboard is pasted under a new name. You can utilize this copying variant to make the destination project the same as the source project, for instance.

Note In the case of both Paste and Paste Special, ProTool always checks the underlying objects (such as the limit value tags of a tag which has been copied) to ensure that existing objects are reusable. If there is already an object of the same name in the destination project, the object to be pasted will be renamed if necessary. It is given the next available name in the destination project.

ProTool User’s Guide Release 12/99

4-15

Creating projects

Example: Tag VAR_4 will be renamed VAR_11 if tags VAR_1 through VAR_10 already exist in the destination project.

What is copied? You can copy the following via the clipboard: •

All objects listed in the project window, such as screens, text or graphic lists, tags etc.

•

Objects from screens (trends, fields, graphics etc.) in the screen editor.

•

Messages and objects from messages (message text, fields, info text etc.) in the message editor.

An object is copied complete with its attributes and all cross-referenced objects. Special situations encountered during copying are reported in the system message window under Clipboard. This gives you information about any objects that have not been copied or renamed, for example.

Special situation with screens If the object to be copied refers to a screen that does not exist in the destination project, the underlying screen is not copied; instead a blank screen is created as a dummy if the destination project does not contain a screen that can be reused. This ensures that you will not copy the complete source project by mistake along with the start screen. Afterward, when you paste the screen via the clipboard, the dummy screen in the destination project will be automatically replaced by the proper screen.

What is not copied? These objects are not copied:

4-16

•

Objects that are unknown in the destination project (such as functions or command buttons when copying from TP27 to OP27)

•

Area pointers

•

Global function key assignments

•

Character sets

•

In the case of multilingual projects, only the languages available in the destination project are copied. No new languages will be created.

Undoing and redoing actions

Purpose During configuration, it may become necessary to cancel actions which have been performed, or to reconstruct actions which have been discarded. The two commands Undo and Redo in the Edit menu are used for this purpose. •

Cancel (Undo) The Undo command (key combination Ctrl-Z) cancels the last action performed. If you keep selecting the command, you can cancel up to 30 successive modifications.

•

Restore (Redo) The Redo command (key combination Ctrl-Y) revokes the last action canceled thus restoring the status before the last Undo command was executed.

Principle Each active editor (project window, screen editor, drivers for WS) has its own undo history. Thus, for example, if three screens are opened at the same time, three separate Undo Histories will be created. When a screen is closed, the actions listed in the accompanying History are deleted. When the project is saved, all the Undo Histories for the current project are deleted. The last recorded action is displayed in abbreviated form in the menu. The Tooltips contain more detailed texts for the Undo and Redo buttons and for the status bar. Example: •

•

Menu Undo: Redo:

VAR_5 edited PIC_2 edited

Tooltip/Status bar Undo: Redo:

property edited of tag VAR_5 contents edited of screen PIC_2

Ctrl-Z Ctrl-Y

Until the accompanying Undo History is deleted, deleted objects will continue to be listed in the cross-reference (Chapter 4.12.1) as used objects. The status of these objects is given in brackets after each object, e. g. PIC_5 (deleted).

ProTool User’s Guide Release 12/99

4-17

Creating projects

General Information The commands Undo and Redo only work with actions taken since the last time the project was saved. If, for example, you move a screen object and then save your project, you cannot later cancel this action. These are some of the rules that apply to Undo/Redo: •

Settings in dialog boxes (properties of a field) can only be canceled in their entirety. It is not possible to open the dialog box and discard individual entries.

•

With multilevel dialog boxes, only changes to the primary object are recorded. Modifications to underlying objects, or creations or deletions cannot be reversed. Example (project window): Editing tags → Editing limit tags. Only the tag changes can be reversed here.

•

4.11.1

Undo/Redo is ProTool-specific. With a project integrated in STEP 7, the Undo buffer cannot be accessed by a higher-level Step 7 Undo Manager.

Components of a screen A screen can consist of static and dynamic components. Static components include text and graphics. Dynamic components are linked to the PLC and visualize current values from the PLC memory. Visualization may take place in the form of alphanumeric displays, trends and bar graphs. Dynamic components are also inputs made by the operator on the operating unit and written to the PLC memory. The link to the PLC is established by means of tags (refer to Using tags (Chapter 5.4.1)).

Screen editor Screens are created with a separate editor in ProTool. The operating unit is displayed when you call the screen editor. Open the screen editor by: •

double-clicking on Screens in the left half of the project window to create a new screen

•

double-clicking in the right half of the project window on an existing configured screen to open the screen for editing.

You can zoom this display in and out by choosing View → Zoom from the menu. If, for example, you wish to edit details you can do it much more simply by zooming in on them. Screens are stored under a symbolic name. You enter a name by choosing Edit → Properties from the menu. This name has to be specified when you edit, reference or delete the screen. In addition, screens are numbered automatically.

Start screen Declare one screen in every project as a start screen. The start screen is the screen that is displayed after the operating unit has started up. To identify a screen as the start screen, select the screen and assign it as the start screen by choosing Edit → Properties from the menu.

Fixed window The fixed window is the window that is always flush with the top border of the operating unit screen. By choosing System → Screen/Keys from the menu, you can open and close the fixed window and adjust its height by dragging with the mouse. Since the contents of the fixed window do not depend on the current screen, you can output important process tags or the date and time to it, for example. You configure the contents of the fixed window in the screen editor. To access the fixed window, click it with the mouse.

ProTool User’s Guide Release 12/99

Configuration techniques

Soft keys/buttons Soft keys are function keys configured for specific screens (refer to What are function keys? (Chapter 5.3.5)). Buttons are virtual keys on the touch-sensitive screen of the touch panel (refer to What are buttons? (Chapter 5.3.6)). You can configure both soft keys and buttons for specific screens. When configuring, you assign functions to these controls. You can illustrate the task of a control by means of a graphic or text. You can use soft keys and buttons to open another screen, turn a motor on and off or display the message buffer, for example.

Selecting screens Every configured screen has to be integrated into the control process so that it can be opened at runtime on the operating unit. The Select Screen function is available for this purpose. You an assign this function to an input field, a function key or a button, for example. You specify the name of the screen as the parameter. This means that a screen can be displayed by means of an input field or a function key or button. With input fields, soft keys and buttons, the function can be used only locally on that screen. Should you wish the function to be available globally, you have to configure the function on a Kx function key on the operating unit or on a button positioned in the fixed window of the TP.

5.1.2

Screen objects in ProTool Screens consist of individual objects. There are different types of object, which you can use at will when configuring a screen. "At will" means that you determine the number and type of the objects, as well as their position and size. ProTool presents you with the following object types: Screen object

Configuration techniques

Character graphics

By using character graphics, you can compose graphics from the individual characters contained in a symbol font. If you use character graphics instead of graphics, the memory requirement for your project file will be reduced significantly.

Graphics

With the graphic field you can use graphics from other graphics programs in your configuration.

Input/output field

With the input/output field, you can enter or display process values directly. Different display formats - for example, decimal and binary - are possible. There are a large number of formatting options, such as colors, flashing, etc.

Symbolic input/output field

Instead of the numerical value of a tag, a text or a graphic is displayed, to make the current status more comprehensible to the operator. The assignment between the values of the tags and the text or graphics is configured in a text or graphic list (text list or graphic list). For example, instead of the numerical values 0 and 1, the phrases Motor Off and Motor On are displayed.

Trend graphics

A trend graphic contains the settings for the coordinate system - for example, the X and Y axes. You can display several different trends on a trend graphic.

Bar graph

Bar graphs display a value from the PLC as a rectangular area. Bar graphs are practical for displaying fill levels, for example.

Button (Touch panels)

Buttons are objects that trigger a function by using a touch-sensitive screen. You can configure the function triggered. Buttons can be freely labeled with text or a graphic.

Configuring display elements

Purpose You use display elements to monitor the machine or the system on the operating unit. You can display current information, such as actual values from the PLC, process and operating modes and malfunctions, on the operating unit as a numerical value, in plain language or as a graphic.

Overview There are essentially two types of display element available for the different tasks: •

Static display elements Static display elements are pieces of text and graphics that are not linked to the PLC. They do not react to user inputs and cannot be modified at runtime on the operating unit. Use static display elements, for example, for system screens or for textual or graphic explanations for controls and dynamic display elements. Static display elements are − Static text ( What is static text? (Chapter 5.2.1)) − Graphics (What are graphics? (Chapter 5.7.1)) − Character graphics (What are character graphics? (Chapter 5.2.2))

•

Dynamic display elements Dynamic display elements can be linked to the PLC by means of tags. They visualize current values from the PLC in alphanumeric or graphic form. Dynamic display elements can change their display spontaneously at runtime on the operating unit without the operator intervening. Use dynamic display elements for all tasks associated with monitoring the process, a machine or the system. Dynamic display elements are − Output fields ( What are output fields? (Chapter 5.2.4)) − Trend graphics (What are trend graphics? (Chapter 5.3.3)) − Bar graphs (What are bar graphs? (Chapter 5.3.4)) − Light indicators (What are light indicators? (Chapter 5.2.5))

Detailed descriptions of the different steps to configuration will be found in the ProTool online Help.

5.2.1

What is static text?

Purpose Static text is text that is not linked to the PLC. It cannot be modified at runtime on the operating unit. Use static text (on one or two lines) to explain segments of a configured screen - for example, for labeling controls and dynamic display elements. You can configure static text separately for any language available on the operating unit.

Fonts Different fonts are available to indicate the relative importance of text strings on a screen by means of the font or the font size. All the characters in the font must be of the same width. This requirement is not met by all fixed-pitch fonts for example, Courier. You can set up to four different fonts for the operating unit. Three fonts are language dependent, one font is language independent. •

Language-dependent fonts With language dependent fonts, you can use different characters for every language available on the operating unit. By default, ProTool fonts are included in the scope of supply. But you can any Windows font, provided that it is a fixed-pitch font.

•

Language-independent font The same language independent font is used in all languages. By default, the symbol set is preset. The symbolism is used for character graphics (What are character graphics? (Chapter 5.2.2)). Configure static text by selecting the symbol illustrated or by choosing Insert → Text from the menu.

What are character graphics?

Purpose Character graphics are static display elements that are not linked to the PLC. They cannot be modified at runtime on the operating unit. By using character graphics, you can compose graphics from the individual characters contained in a symbol font. An example of character graphics is illustrated below.

If you use character graphics instead of graphics, the memory requirement for your project file will be reduced significantly. Configure character graphics by selecting the symbol illustrated or by choosing Insert → Character Graphics from the menu.

Line characters Complete symbol packages are available for user-friendly drawing of polylines. The symbol packages contain symbols for all representations of paths such as horizontal and vertical lines, corners, crosses and bifurcations. The scope of supply contains three fixed symbol packages the line characters single, bold and double. You can customize four other symbol packages (USER 1 through USER 4) to cover your requirements.

What are graphics?

Purpose Graphics are static display elements that are not linked to the PLC. They cannot be modified at runtime on the operating unit. Use graphics, for example, for displaying your system or as explanatory symbolism for dynamic display and controls

Creating graphics ProTool features an option of embedding external graphic editors via the OLE interface. In this way you can create graphics with your usual applications without having to become familiar with a new graphics program. ProTool displays every graphic you are using as a bitmap, irrespective of whether you create the graphic with a pixel-oriented graphics program - for example, Paint - or with a vector-oriented graphics program. Vector graphics are converted into pixel graphics before being displayed in ProTool. Configure graphics by selecting the symbol illustrated or by choosing Insert → Graphic from the menu.

Color presentation on the operating unit With pixel graphics, if you notice differences between the colors displayed on the operating unit and those configured in ProTool, proceed as follows: On the configuration computer, select in the start menu Settings → Control Panel → Display and on the Settings tab, select at Colors the setting True Color. Retain this setting for configuring and compiling the project.

5.2.4

What are output fields?

Purpose Output fields display current values from the PLC on the operating unit. The values may be output optionally in numerical, alphanumeric or symbolic form.

Numerical and alphanumeric output Output fields for numerical or alphanumeric values show the value as a number or as text. A numerical value, for example, is the number 80 as the actual value of a temperature. An alphanumeric value, for example, is the text string Valve_12. Configure output fields for numerical and alphanumeric values by selecting the symbol illustrated or by choosing Insert → Input/Output Field from the menu.

Symbolic output Output fields for symbolic values do not display the true value but, optionally, a text string or a graphic from a text or graphic list. For example, you can store the two states of a valve in a text list or in a graphic list. When the valve is open, the output field then points, for example, to the text string OPEN or to a corresponding graphic. By using output fields for symbolic values, you eliminate misinterpretations on the part of the operator to a large extent, since a symbolic value often presents a state more lucidly than an abstract numerical value, for instance. Configure output fields for symbolic values by selecting the symbol illustrated or by choosing Insert → Text or Graphic List from the menu.

5.2.5

What are light indicators?

Purpose A light indicator is a dynamic display element on a touch panel. Light indicators indicate the state of a defined bit - for example, by means of a change of color or by flashing text. Light indicators are shown with a simple border for visual distinction of buttons which you can press. Configure light indicators by selecting the symbol illustrated or by choosing Insert → Light Indicator from the menu.

Configuring controls

Purpose You use controls on the operating unit to intervene directly in the process. They are used, for example, to specify setpoints, trigger functions, open screens (What are screens? (Chapter 5.1.1)) and acknowledge messages. You can assign a password level to controls in order to prevent manipulation by unauthorized persons.

Overview The following controls are available in ProTool for the different tasks: •

Input fields (What are input fields? (Chapter 5.3.1))

•

Input/output fields (What are combined input/output fields? (Chapter 5.3.2))

•

Function keys/soft keys (What are function keys? (Chapter 5.3.5))

•

Buttons (What are buttons? (Chapter 5.3.6))

By means of dynamic attributes (What are dynamic attributes? (Chapter 5.13.4)) you can indicate, for example, by means of a change of color or by flashing that an operator input is expected at the control in a certain situation. Furthermore, event-driven display and hiding of controls can be performed on the operating unit (Hiding an object (Chapter 5.13.3)). Detailed descriptions of the different steps to configuration will be found in the ProTool online Help.

5.3.1

What are input fields?

Purpose In input fields you enter values on the operating unit that are transferred to the PLC. The values may be input optionally in numerical, alphanumeric or symbolic form. If you define limit values for the input field tag, you can reject inputs on the operating unit that are outside the specified range of values.

ProTool User’s Guide Release 12/99

5-11

Configuration techniques

Numerical and alphanumeric input In input fields for numerical and alphanumeric values you enter the value one character at a time on the operating unit. A numerical value, for example, is the number 80 as the setpoint for a temperature. An alphanumeric value, for example, is the text string Valve_12. Create input fields for numerical and alphanumeric values by selecting the symbol illustrated or by choosing Insert → Input/Output Field from the menu.

Symbolic input In input fields for symbolic values you do not enter the value one character at a time but select this value on the operating unit from a text list. During configuration you assign symbolic text on the text list to every value of a tag. In this way, for example, you can turn a motor on and off by means of the two entries ON and OFF. By using input fields for symbolic values, you prevent misinterpretations to a large extent, since the operating unit accepts only the configured values on the text list. Create input fields for symbolic values by selecting the symbol illustrated or by choosing Insert → Text or Graphic List from the menu.

5.3.2

What are combined input/output fields? Combined input/output fields display current values from the PLC on the operating unit. You can also enter values that are transferred to the PLC at the same time. The values may be input and output optionally in numerical, alphanumeric or symbolic form. During input, the value you want to be output is not updated on the operating unit. If you define limit values for the input/output field tag, values that are outside the specified range can be •

rejected upon input

•

displayed in a different color, for example, when read out. Create combined input/output fields by selecting the symbol illustrated or by choosing Insert → Input/Output Field from the menu. Create input fields for symbolic values by selecting the symbol illustrated or by choosing Insert → Text or Graphic List from the menu.

5.3.3

What are trend graphics?

Purpose A trend graphic is a dynamic display element. Trend graphics make possible a particularly lucid form of continuous display of process data on the operating unit. In a trend graphic, you can display several different trends (What are trends? (Chapter 5.8.1)) simultaneously on your operating unit. Configure trend graphics by selecting the symbol illustrated or by choosing Insert → Trend Graphic from the menu.

5.3.4

What are bar graphs?

Purpose A bar graph is a dynamic display element. Bar graphs display a value from the PLC as a rectangular area. This means that you can tell at a glance on the operating unit how far the current value is from the limits or whether a specified setpoint has been reached. Bar graphs can be used to display fill levels or quantities, for example. Configure character graphics by selecting the symbol illustrated or by choosing Insert → Bar Graphs from the menu.

Settings Bar graphs are linked to the PLC by means of a tag. Apart from this tag, which contains the value that is required to be displayed, you can define other tags in order, for example, to visualize when a limit value has been reached or to display or hide the bar field. You can freely define the direction, scaling, bar and background color and also labeling of the Y axis. You can also display upper and lower limit value lines for indicating limit values. The following figure shows a bar that is updated vertically and has limit value lines drawn on it.

What are function keys? A function key is a key on the operating unit for configuring a function assignment. You can assign one or more functions to any function key in ProTool. The functions are triggered as soon as the key is pressed. The function key assignment may be locally or globally significant. You can assign a password level to function keys in order to prevent manipulation by unauthorized persons.

Global assignment Globally assigned function keys always trigger the same function, irrespective of the current control situation. You can the open a specific screen, for example, display queued messages or print the contents of the screen. By using globally assigned function keys, you cut your configuration effort considerably since you do not have to assign individual functions to global keys on every screen. Assign function keys globally by choosing System → Screen/Keys from the menu. To do this, click in the Screen/Keys dialog box on one of the keys K1 through KX or F1 through FX. You can specify the functions you have assigned to specific keys on the operating unit by means of labeling strips. Note By choosing System → Screen/Keys you can specify global settings for keys that apply to all screens. The icons appear in each configured screen provided the settings are not subsequently overwritten by an individual screen. In that case, the changes apply only to that particular screen.

5-14

ProTool User’s Guide Release 12/99

Configuration techniques

Local assignment Locally assigned function keys trigger different actions on the operating unit depending on the screen. A function key whose assignment may vary from screen to screen is referred to as a soft key. Assign soft keys locally in the screen editor. To do so, click in the screen on one of the keys F1 through FX, which are arranged directly around the operating unit screen. You can assign an icon that illustrates the soft key function by means of text or a graphic to any soft key. You can also assign soft keys globally. A global assignment is active on all screens to which you do not assign a screen-specific function. Use globally assigned soft keys, for example, to change from any screen to the same system screen. Note Do not assign functions that have to be permanently available on the operating unit to soft keys.

5.3.6

What are buttons?

Requirements Buttons can only be configured for touch panels. Before you start configuring buttons, you should give a thought to the basic partitioning of the touch panel screen (refer to Configuration notes for the touch panels (Chapter 4.7)).

Purpose A button is a virtual key on the touch panel screen to which you can assign one or more functions. You operate a button by touching the touch-sensitive screen. You can customize the user interface by means of buttons. You can assign a password level to buttons in order to prevent manipulation by unauthorized persons.

Labeling You can label buttons statically or dynamically with text or graphics. •

Static labeling: When configuring the button enter a text or select a graphic. This type of labeling is static, which means that it is not changed on the touch panel.

ProTool User’s Guide Release 12/99

5-15

Configuration techniques

•

Dynamic labeling: When configuring the button, select a text or graphics list and an associated index tag. The value of the index tag determines which list element is displayed on the button at runtime.

Operation Pressing or releasing a button triggers the functions that you set for these events. To prevent the triggering of a function of a button that has been pressed by mistake, move your finger from the button while still keeping the button pressed. This process is not interpreted as a click event.

Check-back indication upon operation When the button is pressed and released, it is animated by a change in border color as is usual in Windows. Invisible buttons do not provide an optical checkback indication upon operation.

Invisible buttons Invisible buttons are transparent buttons that are not displayed upon the operating unit. If you place invisible buttons on graphics, you can operate parts of the graphic - for example, a motor or a valve - by touching the touch panel.

Buttons with a freely definable function You can create on an individual basis, using a button with freely definable function, all the buttons that you need for operating the TP. Create buttons by selecting the symbol illustrated or by choosing Insert → Button from the menu.

Buttons with a permanent function ProTool features predefined buttons that can be operated and have the following functions for quick and efficient configuration of standard functions for touch panels:

5.3.7

Using buttons as direct keys

Purpose You can also configure buttons on the TP as direct keys in order to allow keyboard shortcuts without the usual delays caused by communications. Keyboard shortcuts are a requirement for typing mode, for example.

Direct key types Basically, you can configure two different types of direct key: • PROFIBUS direct keys • direct keys for controlling the direct key module Simultaneous use of PROFIBUS direct keys and direct keys for the direct key module is not possible within the same project.

PROFIBUS direct keys With PROFIBUS direct keys, you set bits on the TP directly in the I/O area of the SIMATIC S7. The bit area is defined in STEP 7. The bit is set when the direct key is touched and reset when the key is released or when you quit the screen. Requirements: 1. You have installed ProTool as integrated at the time the configuration is compiled. 2. The touch panel is connected to a SIMATIC S7 over the PROFIBUS-DP during operation. 3. You have defined the bit area for direct keys in STEP 7 (you will find configuration tips in the Communication User’s Guide). If all these requirements have not been fulfilled, ProTool interprets the configured button as a direct key for driving the direct key module. The number of PROFIBUS bits that can be manipulated by means of direct keys depends on the touch panel:

Direct keys for the direct key module You can use these direct keys to drive the outputs (ports) of the optional direct key module at the back of the TP. The port is set when the direct key is touched and reset when the key is released or when you quit the screen. Requirements: The TP is equipped with a direct key module and the requirements for PROFIBUS direct keys are not met. The number of ports that can be configured depends on the touch panel:

5.3.8

Using PROFIBUS screen numbers If PROFIBUS direct keys use identical bits for different functions on different screens, the S7 has to decide on the functionality concerned via the screen number. To avoid delayed updating of the screen number on the PLC following a change of screens, there is the PROFIBUS Screen Number screen function. To use this function, choose Edit → Properties from the menu. On the Functions tab, assign the PROFIBUS Screen Number function to the current screen at Screens. For the parameter, specify a PROFIBUS bit that you want to have reserved for the screen number and have set when the key is pressed. If you assign this function several times, you can define a bit pattern for the screen number. The bits are set when the screen is opened and reset when you quit the screen. The screen number bits are transferred to the SIMATIC S7 at the same speed as the direct key bits.

5.3.9

Buttons with fixed functions When you configure a touch panel, ProTool offers a selection of different buttons that are already assigned frequently used functions: • Set/Reset Bit and Set/Reset Bit in Word •

Select Screen • Light Indicator You will find detailed information on this in What are buttons? (Chapter 5.3.6) Note As with any other operating unit, instead of using these buttons you can use a normal button and configure the function you require manually.

Using tags

Overview Since tags are the most important means of communication between the operating unit and the PLC and for exchanging data, a detailed explanation is presented here of what tags are and what types of tag are used in ProTool.

5.4.1

What are tags?

Definition A tag has a symbolic name and a defined data type. The value of the tag changes while the PLC program is being executed. Tags with a PLC link are referred to as global tags. Tags without a PLC link are known as local tags. • Global tags A tag with a PLC link occupies a defined memory address on the PLC, to which read and write access is possible from both the operating unit and the PLC. • Local tags Local tags are not connected to the PLC. They are available only on the operating unit. You create local tags, for example, so that the operator can enter limit values on the operating unit.

Tag types ProTool recognizes the following tag types (but these are not available on every PLC):

Properties of tags To define a tag, set the properties of the tag. The following figure shows an example of the Tag dialog box for the SIMATIC S7.

Tag Dialog Box for the SIMATIC S7

Tag definition (Section A) The available data types and data formats depend on the PLC you selected. You select them in the Tag dialog box at Type of a tag (see ProTool online Help).

Updating tags The acquisition cycle determines the time interval in which the value of a tag is updated on the operating unit.

ProTool User’s Guide Release 12/99

5-21

Configuration techniques

Result: •

If 0 is entered for the acquisition cycle, the tag is updated only when a screen is called and then not updated any more.

•

If a value > 0 is entered for the acquisition cycle of a tag, the tag is updated periodically in the specified time and also when the screen is opened.

System default setting: 1 sec The acquisition cycle is a multiple of the standard clock pulse, which you configure for every PLC in the PLC dialog box. You globally modify the acquisition cycles for all the tags of a project by setting the standard clock pulse.

Array tags An array tag represents a number of tags of the same type with consecutive memory addresses. If you wish to define an array tag, enter the number of elements in the array in the Tag dialog box at Number Elements. The system default setting is 1, in other words, the tag is not defined as an array. The maximum number of elements in an array is 640.

Tip You can use array tags for pattern trends, for example (see ProTool online Help).

Address (Section B) The address determines the memory location of a global tag on the PLC. The address therefore depends on the PLC you are using. The display of the address depends on the PLC you selected. This section of the Tag dialog box adjusts dynamically to the programmable address areas.

ProTool integrated in STEP 7 (Section C) If you have installed ProTool in STEP 7 on an integrated basis, you can access the STEP 7 symbol table directly in the Tag dialog box. For performance reasons, ProTool does not automatically update the STEP 7 symbol table after every change. In order to make the latest changes to the STEP 7 symbol table available in ProTool, update the display of the symbol table in the Tag dialog box by clicking Update. See the example in online Help with regard to the definition of an entity DB in the symbol table.

ProTool User’s Guide Release 12/99

Configuration techniques

Setting a start value You can set a start value for the tag at Options. When the project is downloaded, the tag is assigned the start value. The start value is displayed only on the operating unit and is not stored on the PLC. Example: If tags are used for scaling trends and bar graphs, the initial value may be the start value of the scaling.

Remark This is not useful for tags of the type STRING.

Setting limit values An upper and a lower limit value can be configured at Limit values for tags. If the tag value is outside the defined range, in other words, it is higher or lower than the limit value concerned - this has the following effect on the input fields, for example. If the operator enters a value outside the configured limit values, the input is rejected and the original value is retained.

Configuring tags with functions You can assign functions to tags in input/output fields - for example, the Select Screen function. The screen is selected as soon as the value of the tag changes.

5.4.3

Updating tags At Options, you set how the values are transferred between the operating unit and the PLC and updated: •

Write directly (system default setting) After being entered on the operating unit, the tag value is written directly to the PLC address.

•

Write indirectly (only possible for SIMATIC S5 and SIMATIC S7) In the case of indirect writing, the tag value on the PLC is written to an address area, called the data mailbox. In order to ensure the coordinated execution of the transfer and prevent unwanted overwriting of the tag value in the data mailbox, bits are set in the interface area. The value can be fetched by the PLC program from the data mailbox at the appropriate time. By selecting Write indirectly, you can configure up to three identifications for every tag, which are likewise written to the data mailbox. You will find further information in the Communication User’s Guide.

ProTool User’s Guide Release 12/99

Configuration techniques

•

Read continuously The tag is updated continuously, even if it is not on the open screen. This is important with trends. One trend is normally required to be plotted when the screen is not selected.

•

ONLINE If you select ONLINE (default setting), the tag is serviced during operation. If you deselect ONLINE, the tag is disconnected from the PLC during operation. You can use this, for example, if you are taking only parts of the system into operation.

5.4.4

Example: How to set the acquisition cycle and the standard clock pulse System default setting: standard clock pulse 500 ms, acquisition cycle 1 s. Set the standard clock pulse in the PLC dialog box. If you increase the standard clock pulse to 1000 ms, the acquisition cycle for all tags is increased to 2 s.

Tip In order not to overload communication between the PLC and the operating unit, the times you set for the standard clock pulse should not be too short. This would mean that other processes, such as the updating of trends or the execution of PLC jobs, would take considerably longer.

5.4.5

Example: Scaling tags The scaling of tags is configured as a function relating to a tag. The following functions are available for this: •

Scaling Linear 1 and Scaling Linear 2

•

Scaling Square 1 and Scaling Square 2.

If you configure no scaling, the tag value on the PLC corresponds to the tag value on the operating unit.

5-24

ProTool User’s Guide Release 12/99

Configuration techniques

Linear scaling Scaling can be configured for any tag in the form y = a*x + b. •

X = displayed value/input value The Y value read from the PLC undergoes linear scaling before being displayed on the operating unit as the X value. Inputs X on the operating unit undergo scaling before being written to the PLC as the Y value.

•

X = displayed value/input value The Y value read from the PLC undergoes linear scaling before being displayed on the operating unit as the Y value. Inputs Y on the operating unit undergo scaling before being written to the PLC as the X value.

Example You have configured 3 as the value of a6 as the value of b. The value 21 is transferred from the PLC. It is inserted in the conversion formula, thus: 21 = 3 * X 6. This produces a value of 5 for X. That value is displayed on the operating unit.

Square scaling Scaling can be configured for any tag in the form: y = a * x^2 + b * x + c. •

X = displayed value/input value The Y value read from the PLC undergoes square scaling before being displayed on the operating unit as the X value. Inputs X on the operating unit undergo scaling before being written to the PLC as the Y value.

•

Y = displayed value/input value The X value read from the PLC undergoes square scaling before being displayed on the operating unit as the Y value. Inputs Y on the operating unit undergo scaling before being written to the PLC as the X value.

Example You have configured a value of 2 for a, and a value of 3 for b and 6 for c. A value of 71 is transferred from the PLC. It is inserted in the conversion formula, thus: 71 = 2 * X^2 + 3 * X + 6. This produces a value of 5 for X. That value is displayed on the operating unit.

Multiplexing

5.5.1

What is multiplexing?

Purpose When multiplexing, you assign several tags to trends, bar graphs or input/output fields, not just one. Assignment depends on the value of an index tag. A tag, selected at runtime, is assigned to each of the index tag values. Using the index tag, you can control all the tags of a screen, for example. This spares you the trouble of configuring several screens for similar applications.

Applications You can multiplex the following objects:

5.5.2

•

Bar graphs (Chapter 5.5.2)

•

Trends (Chapter 5.5.4)

•

Trend tags (Chapter 5.5.5)

•

Input/output fields (Chapter 5.5.6)

Multiplexing bar graphs

Purpose When you configure a bar graph, you define in advance the tag from which you want the values to be read and displayed on the operating unit. If you multiplex bar graphs, the assignment of the bar graph to a tag is not static but depends on the value of an index tag. This allows you to determine several tags whose values are displayed, depending on the situation, as bar graphs at runtime.

Principle Selection of the tags is controlled by means of the index tag. Every index tag value has assigned to it a tag, with values read and displayed. The figure shows the principle of multiplexing bar graphs by means of three examples.

Multiplexing bar graphs (principle)

In the bar graph shown, the contents of tanks T1, T2 or T3 are displayed on the operating unit as a function of the index tag value VAR_S1. The tank contents are read from tags VAR_1 through VAR_3.

5.5.3

Example: How to multiplex a bar graph In the following example, three values of index tag VAR_S1 are assigned tags VAR_1 through VAR_3. The PLC is a SIMATIC S7. 1. On the General tab, click the Multiplex button. 2. Configure index tag Var_S1. The value of the index tag determines at runtime which tag is selected as a bar graph. Select this button under index tag. In the Tag dialog box, enter the symbolic name Var_S1 and the following values. Type: INT DB: 15 DBW: 0 PLC: PLC_1 VAR_S1 accepts the values 0, 1 or 2. Each of these three values is now assigned a separate tag.

In the Tag dialog box, enter the symbolic name Var_1 and the following values: Type: INT DB: 16 DBW: 1 PLC: PLC_1 Now click the Add button. The tag VAR_1 is accepted into the list and VAR_S1 is assigned to the value (index) 0 of the index tag. Repeat this step with Var_2 and Var_3. 4. Confirm by clicking OK. A small cross now appears on the Multiplex button to indicate that multiplexing is being used. The index tag is specified instead of the tag.

5.5.4

Multiplexing trends

Purpose When you configure a trend graphic, you determine in advance the trends that you want to have displayed on the operating unit. If you multiplex trends, selection of the trends is not static but depends on the value of an index tag. This allows you to determine which trends are shown in the different situations at runtime.

Principle Selection of the trends is controlled by means of the index tag. A trend is assigned to every index tag value. The figure illustrates the principle of multiplexing trends.

Multiplexing trends (principle)

Temperature values Temp1 through Temp3 are stored in DB 10 on the PLC at addresses DW 37, DW 39 and DW 41. Tags Var1 through Var3 are configured for these addresses. A trend buffer is created for every single tag on the operating unit. The size of the trend buffers depends on the configured number of samples/max. The value of index tag Var_A determines the buffer from which the values come for the trend graphic you want to have displayed. With this type of multiplexing, all the trends are up to date in the background.

5.5.5

Multiplexing trend tags

Purpose The standard case is to set up a separate trend buffer for each trend to be displayed on the operating unit. When multiplexing trend tags, write, depending on the value of an index tag, different trend tags to a common trend buffer. This means that a trend graphic will have displayed in it a trend with values read out from the trend buffer by different tags. This allows you to determine which trends are required to be shown in the different situations at runtime. At the same time, you save storage space on the operating unit by using a common trend buffer.

The value of index tag Var_A determines which tag writes values to the trend buffer. With this type of multiplexing, it is possible to display a larger number of process values as a trend, since separate trend buffers are not created for every trend.

5.5.6

Multiplexing input/output fields When you configure input or output fields, you define in advance the tag in which inputs are applied and from which values required to be output are read. If you multiplex input and output fields, the assignment to a tag is not static but depends on the value of an index tag. This allows you to determine several tags whose values can be displayed, depending on the situation, in an output field at runtime or entered in an input field and modified.

Creating text or graphic lists

Purpose Text or graphics are often more meaningful than abstract values. For example, the pieces of text full and empty or two graphic symbols present the state of a tank more lucidly than the corresponding numerical values. Which is why ProTool gives you the opportunity to configure text or graphic lists. These text or graphic lists are lists in which you assign an element from the list to each tag value.

Usage With text or graphic lists, for example, you can label buttons dynamically, display text or graphics in output fields and select texts for input in input fields. To a large extent, this eliminates misinterpretations in the display and operator errors during input. Further information on using text or graphic lists in a screen can be found under •

Input fields (Chapter 5.3.1)

•

Output fields (Chapter 5.2.4)

•

Buttons (Chapter 5.3.6)

Text list A text list assigns text to every value of a tag. At runtime, the tag value determines which text is selected from the list and displayed, for example, in an input/output field on the operating unit. To create a new text list, double-click Text or graphic lists in the project window.

Graphic list A graphic list assigns a graphic to every value of a tag. At runtime, the tag value determines which graphic is selected from the list and displayed, for example, in an output field on the operating unit. To create a new graphics list, select the symbol illustrated on the open screen.

Graphics creation

5.7.1

What are graphics?

Purpose Graphics are static display elements that are not linked to the PLC. They cannot be modified at runtime on the operating unit. Use graphics, for example, for displaying your system or as explanatory symbolism for dynamic display and controls

Creating graphics ProTool features an option of embedding external graphic editors via the OLE interface. In this way you can create graphics with your usual applications without having to become familiar with a new graphics program. ProTool displays every graphic you are using as a bitmap, irrespective of whether you create the graphic with a pixel-oriented graphics program - for example, Paint - or with a vector-oriented graphics program. Vector graphics are converted into pixel graphics before being displayed in ProTool. Configure graphics by selecting the symbol illustrated or by choosing Insert → Graphic from the menu.

Color presentation on the operating unit With pixel graphics, if you notice differences between the colors displayed on the operating unit and those configured in ProTool, proceed as follows: On the configuration computer, select in the start menu Settings → Control Panel → Display and on the Settings tab, select at Colors the setting True Color. Retain this setting for configuring and compiling the project.

Creating trends

5.8.1

What are trends?

Usage •

Realtime trend With a realtime trend only one trend value at a time is read from the PLC for each time unit (clock pulse) and added to the trend displayed on the operating unit. Realtime trends are suitable for displaying slow, continuous patterns.

•

Pattern trend With a pattern trend, all trend values are read simultaneously from the PLC and displayed as a trend on the operating unit by setting a trigger bit. Pattern trends are suitable for displaying rapid changes if the trend variation, seen in its entirety, (profile) is more interesting than individual values.

Trigger: The trigger type defines how trend data is read in: •

Clock trigger (time triggered) In the case of a clock trigger, the data that has to be acquired in the trend is read from the PLC in a fixed, adjustable time slot. To do this, select Read Continuously on the Options tab when you configure the tag. If the configured number of samples has been reached, the oldest value is overwritten by every new one. By means of the specified time slot and the number of samples you want to have displayed, you set the period of time that has to be covered by the trend data. This type of trigger is suitable for realtime trends.

•

Bit trigger (event triggered) In the case of a bit trigger, data to be acquired on a trend is read in on an event-triggered basis. The event is triggered by the PLC as a result of setting a defined bit. There are two possibilities of reading in trend data: − Single-value acquisition Only one value is read from the PLC every time a bit is set. Single-value acquisition is suitable for displaying realtime trends. − Buffered data acquisition Buffered data is read out from the PLC as an entire block every time a bit is set. Buffered data acquisition is suitable for displaying pattern trends.

ProTool User’s Guide Release 12/99

5-33

Configuration techniques

Communication areas for bit-triggered trends For you to be able to configure bit-triggered trends, you have to set communication areas by choosing System → Area Pointer from the menu and create them on the PLC. The operating unit and the PLC communicate with each other via these areas: •

Trend request area This area can be used by the PLC to evaluate which trend is currently being displayed on the operating unit.

•

Trend transfer area 1 This area is used to trigger the trends.

•

Trend transfer area 2 This area is required only for trends that you configure with a switch buffer.

A specific trigger bit is assigned to every trend in all bit areas. If, for example, you have assigned trigger bit 4 to a trend, that trend will be identified by bit 4 in all bit areas.

Switch buffer A switch buffer is a second buffer which you can create for a pattern trend. While the operating unit is reading the trend values from buffer 1, the PLC can already write the new values to buffer 2. When the operating unit is reading buffer 2, the PLC is writing to buffer 1. The switch buffer prevents the PLC from overwriting values while the operating unit is reading the trend.

5.8.2

How a bit trigger works When a screen containing a trend graphic with one or more bit-triggered trends is opened on the operating unit, the operating unit sets the bits assigned to the individual trends in the trend request area in each case. From the bits set, the PLC can evaluate which trends are currently being displayed on the operating unit. If the PLC program now sets both the bits assigned to the trends and the trend communication bit in the trend transfer area, the operating unit detects the trigger. It resets the trend bits and the trend communication bit and, depending on the configuration, reads out one value or the entire buffer. As soon as the conditions for a new trigger have been met, the PLC program sets the trend bits and the trend communication bit again. Once the screen has been deselected, the operating unit resets the bits set in the trend request area. Define the trend request area and trend transfer area by choosing System → Area Pointers from the menu. You will find a description of these data areas in the Communication User’s Guide.

Note The position of the communication bit in the trend transfer area depends on the PLC you set. Do not use this bit for the identification of bit-triggered trends.

5.8.3

Array tags for pattern trends You can configure array tags for pattern trends. You use the number of elements to set the size of the trend buffer. This number has to be identical to the number of samples you set for the trend. The pattern trend is represented by the array tag. If you use this array tag in a recipe, you can save the pattern trend to a data medium on the operating unit and read it back in, just like you would with any other data record. Additional information on tag types can be found under Using tags (Chapter 5.3.1).

5.8.4

Interrupting the recording of trend data If you interrupt operation of the operating unit while clock-triggered trends are being recorded, the X axis with the time label is updated immediately upon restarting. The trend values are, however, updated at the configured clock-pulse rate and therefore temporarily do not correspond to the time values displayed.

ProTool User’s Guide Release 12/99

5-35

For this reason, the vertical bar displayed on the screen is shown in the trend graphic when recording restarts. The bar represents the time of interruption and migrates continuously at the configured clock-pulse rate out of the trend graphic.

Configuring messages

Overview To display process and operating states or to acquire and log process data on the operating unit that you obtain on the process from the PLC, configure messages. Messages are initiated by the PLC and can be displayed on the operating unit.

5.9.1

Reporting operating and process states There are the following message types in ProTool: •

Event messages display routine operating and process states and processes.

•

Alarm messages display critical or hazardous operating and process states and require operating personnel to react by issuing an acknowledgement.

•

System messages display states and faults of the operating unit, the PLC or the communications between them. They are issued by the operating unit or by the PLC.

For what purpose do you use messages? The messaging system is responsible for the following tasks: •

Reporting events or states that can occur on the system or in the process: − A state is reported immediately following its occurrence. − The messages are presented to the operator as a function of their significance (priority).

•

Support in eliminating the cause of error conditions: − Messages provide in-depth information on the causes of errors (diagnostics). − The process can be influenced as a result of the message.

•

5.9.2

Printout: the message events are output to a printer.

What goes into a message? A message consists of: •

a message number

•

message text

•

a message tag

•

The following messages are displayed on the operating unit but cannot be edited in ProTool: •

The message number cannot be modified in system messages, standard S7 diagnostic results (S7 system messages) and NC alarms. (only with OP7 and OP17).

•

Message numbers of user defined S7 diagnostic results can be freely defined in STEP 7 within certain limits.

•

The message number is assigned to Alarm_S messages in STEP 7.

Message number The message number is used to reference a message. In ProTool, you have a free choice of message number (within the range 0 to 2000) and message text.

Message text Message text contains the description of a message. The length of the message text depends on the operating unit. The number of characters per line is marked by this character at the top border of the window during configuration. By choosing Edit → Style from the menu, you can select from the following styles for the message text, depending on the operating unit: flashing, underscore, italic, and capitals (text-based displays only).

Tip You can also configure operator instructions as a message.

Message tags A message can contain output fields with tags. They are also referred to as message tags. By choosing Edit → Style from the menu, you can select from the following styles for output fields, depending on the operating unit: flashing, underscore, italic. Insert an output field by selecting the symbol illustrated.

Note The values of message tags are updated in the message buffer when messages are active or are cleared, but not when messages are acknowledged.

What parameters do you set for messages? You can configure the following parameters for messages: •

priority

•

acknowledgement group

•

Priority High-priority messages are displayed before low-priority messages on the operating unit. The lowest priority is 1. •

If several messages having the same priority are waiting to be displayed, the most recent (last) is displayed.

•

If several unacknowledged alarm messages having the same priority are waiting to be displayed, you can choose whether the most recent (last ) or the oldest (first) should be displayed.

Configure the priority in the Attributes dialog box for every single message. Set the sort criterion by choosing System → Messages → Settings from the menu.

Acknowledgement group Alarm messages can be assigned to acknowledgement groups. Configure the assignment to an acknowledgement group for every single message. If you acknowledge an alarm message in one acknowledgement group, all the alarm messages in that group are acknowledged simultaneously (group acknowledgement).

Print If you select Print, the message event (active, cleared, acknowledged) is logged automatically on the printer if you selected, at System → Messages → Settings, Print on Message Event. Configure printing in the Attributes dialog box for every single message.

Port / relay If you select Relay, the "active" message event automatically drives the relay on the operating unit. If you select Port, the "active" message event automatically drives a port on the operating unit. For this you have connect a direct key module (DKM) to the operating unit. You can configure the following ports for the different operating units: OP25, OP27, TP27 OP35, OP37, TP37

Ports 1 - 8 Ports 1 - 16

Configure Port / Relay for every single message in the Attributes dialog box.

5.9.4

Acknowledging messages

Principle An alarm message can be acknowledged either by the operator on the operating unit or by the PLC program. By acknowledging an alarm message, you confirm that you have taken notice of it.

Assigning acknowledgement groups You can assign several alarm messages to a single acknowledgement group when you configure alarm messages. This means that when the first alarm message is acknowledged – for example, the cause of the malfunction- all the other alarm messages in the same acknowledgement group (consequential malfunctions) are acknowledged together. A blank field in the message editor Attributes window is equivalent to entering 0. The value 0 results in individual acknowledgement, i.e. when an alarm message is acknowledged, only that alarm message is acknowledged. If you acknowledge an alarm message in one acknowledgement group, all the alarm messages in that group are acknowledged simultaneously (group acknowledgement). You can allocate the messages to one of 16 acknowledgement groups.

•

Buffer overflow When the specified remaining buffer capacity is reached, all messages are printed out irrespective of whether printing is enabled or not. The message buffer is then deleted.

•

Off Message logging is disabled.

You use the Message Log ON/OFF function to enable and disable printing of messages (refer to Functions). You will find more information on that topic in What is in the message buffer? (Chapter 5.9.13)

5.9.11

Configuring printers for the operating unit Attach a printer to your operating unit for the printout of process states or process data reports. For this you can configure one or more printers. •

In ProTool, some printers in the list box have already been defined. Parameters have already been assigned to these printers.

•

You can add more new printers to the list box in ProTool. You have to enter the specific control characters contained in the printer manuals concerned for these printers.

Perform the settings for the printers and the interface parameters by choosing System → Printer from the menu.

Tip Use the Z_PRINTER standard screen belonging to the standard configuration.

5.9.12

Displaying messages on the operating unit Messages are displayed in special process windows. Set the properties of the following objects by choosing System → Screen/Keys from the menu: •

Message window/message line Messages are output here.

•

Message indicator Indicates that alarm messages are pending or must be acknowledged. The message indicator is used for acknowledging messages on touch panels.

Sort criterion for alarm messages If several unacknowledged alarm messages of the same priority are queued, select the sort criterion by choosing System → Messages → Settings from the menu: First

The first (oldest) alarm message is displayed first.

Last

The last (most recent) alarm message is displayed first.

If you configure the function Alarms - Display First/Last, you can change the sort sequence in the operating unit too.

Tip This function has already been implemented on the System Settings standard screen of the standard project (refer to Standard Screens).

Standby message The standby message is a special event message. The standby message is event message number 0. It is displayed on the message bar if no other message is pending on the operating unit. Note The standby message can have only message text and output fields containing the date and time.

5.9.13

What is in the message buffer?

Definition A message buffer is a memory area with battery backup in the operating unit RAM in which message events are stored in chronological order. It takes the form of a FIFO buffer with a specified size and does not have to be explicitly configured. The size of the message buffer is 512 message events.

Data storage in message buffer Every message event is stored with the following information: • message number • event identification (A for Arrived, D for Departed, K for AcKnowledged) • time stamp consisting of date and time • acknowledgement group QGR (with alarm messages only) • message text • value of the message tag at the time of arrival or departure

In the case of the Acknowledged message status, the operating unit does not acquire any current process values. The characters ### stand for the value.

Behavior on overflow Under System → Messages → Settings you can select whether an overflow warning is to be output when the specified remaining buffer capacity is reached. Before the messages are deleted, they are output to the printer. This applies to all messages even if they are not marked with the attribute Print.

Using a standard screen The following functions have already been implemented on the standard screen known as Edit Message (Z_MESSAGES): •

What does the message indicator show? Set display of the message indicator on the operating unit by choosing System → Screen/Keys from the menu. The message indicator indicates that alarm messages are waiting. •

As soon as an alarm message is waiting, an alarm message window and the message indicator are displayed.

•

As soon as at least one unacknowledged alarm message is queued, the message indicator flashes.

Message indicator on touch panels On touch panels, the message indicator is an operable button and is used to acknowledge alarm messages. It cannot be hidden for that reason. The message indicator may assume two states: •

flashing: as soon as at least one unacknowledged alarm message is queued.

•

static: when all queued alarm messages have been acknowledged but at least one of them is not yet cleared. Not until all acknowledged messages have departed is the message indicator hidden. In this way it is not possible fore you to forget queued alarm messages.

If the alarm message window is shown on top, the alarm message page is opened by touching the message indicator. At each touch you can toggle between the alarm message buffer and the alarm message page.

5.9.16

What communication areas are required for messages? For communication between the operating unit and the PLC functions properly, choose System → Area Pointers from the menu and establish in your project an assignment to the following communication areas: event messages and/or alarm messages These areas are imperative if you have configured event messages and alarm messages. They must be chosen at least large enough for a bit to be available for every configured message. If the communication area is not made large enough, a warning will be issued during compilation of the project.

If you wish, you can create the following communication areas:

5.9.17

•

PLC acknowledgement

OP acknowledgement

Optional communication areas for messages If you want the acknowledgement to come from the PLC, you have to create the following acknowledgement areas by choosing System → Area Pointers from the system. •

PLC Acknowledgement The acknowledgement bit is set by the PLC program and thus causes acknowledgement of the corresponding alarm message to be displayed on the operating unit. The PLC Acknowledgement acknowledgement area − has to be contiguous with the associated alarm message area − has to have the same acquisition cycle as the alarm messages area − can have the same length as the associated alarm area at most.

•

OP Acknowledgement The operator acknowledges an alarm message on the operating unit and thus sets the acknowledgement bit of this alarm message on the PLC. When he does so, the entire acknowledgement area is transferred to the PLC. The OP Acknowledgement acknowledgement area may have the same length as the associated alarm message area at most.

Message procedure

5.10.1

How are messages initiated?

Message procedure: The message procedure identified the transfer path of messages and thus also the parameters of the messages. The message procedure in ProTool is the message bit procedure. With this message procedure, the operating unit detects the arrival, departure or acknowledgement of a message by setting a bit in the address area, the bit being assigned by choosing System → Area Pointers from the menu to the event/alarm message area. A message is event-driven and is issued when a bit is set in the PLC. The setting, resetting and acknowledging of the bit is known as a message event. Active (K)

The message bit has been set and the message is waiting to be displayed.

Cleared (G)

The message bit has been reset because the cause that gave rise to the message no longer exists.

Acknowledge (Q)

With alarm messages only: The operator (or the PLC) acknowledges the message to confirm the noting of the message.

The message events have been acquired by the operating unit and time stamped. The operating unit automatically enters all the message events in the message buffer. In this way the message events can be viewed at a later time again.

Communication areas for messages The display of messages on the operating unit is initiated by the PLC by a bit being set on it in a defined communication area. You can see which communication areas for messages have to be created on the PLC in the following figure:

Message number procedure ALARM_S

Overview This chapter gives detailed information on the ALARM_S message number procedure. It will show you how ALARM_S differs from the message bit procedure and how the system behaves in the event of critical bottlenecks.

Requirements You can only configure ALARM_S messages to be displayed on the operating unit if you are using a SIMATIC S7 PLC and ProTool has been integrated into STEP 7.

Tip It is considerably simpler to configure ALARM_S messages if you have installed S7-PDIAG.

5-52

ProTool User’s Guide Release 12/99

Configuration techniques

What is ALARM_S? ALARM_S is a message number procedure. The message numbers are issued automatically during the configuration process in STEP 7. The numbers are used as the basis for assignment of the correct message text. When a fault arises, the operating unit receives a message containing the message number. On the basis of the number, the corresponding message text is identified and displayed. The S7-CPU stores not only the status of the message (arrived, departed, acknowledged) but also the time. This information is not discarded immediately after the messages have been sent, either, so individual network components (for example, operating units) can log on later and update.

Advantages of ALARM_S As compared with the message bit procedure, ALARM_S has the following advantages: •

ALARM_S is an active message procedure. When a message is issued, the CPU actively notifies all networked units. The operating unit is relieved of the task of continually polling the message area.

•

The process data always precisely reflects the situation at the time of the message. This cannot be guaranteed with the message bit procedure.

•

The time stamp precisely indicates when an event occurred even if the operating unit is not connected until a later time.

Display classes Individual messages can be assigned different display classes in STEP 7. When configuring in ProTool, you then can then choose a specific selection of display classes for an operating unit. In that way you can distribute the messages selectively between different display units.

Priorities You can assign the messages different priorities when configuring ALARM_S messages as well.

Tip Make sure that you assign messages that can bring about consequential errors a higher priority than the consequential errors themselves.

ProTool User’s Guide Release 12/99

5-53

Configuration techniques

Types of ALARM_S messages With message configuration in STEP 7, there are two types of ALARM_S messages: alarm messages and event messages.

Remark You can configure in STEP 7 whether an ALARM_S message needs to be acknowledged or not.

Configuring ALARM_S messages ALARM_S messages are not configured in ProTool but in STEP 7 (refer to Configuring ALARM_S messages (Chapter 5.10.5)). The advantage of this is that the messages are compiled centrally and only have to be created once.

5.10.3

Display classes

What are display classes? An S7-CPU always issues ALARM_S messages to all stations that are logged in. However, it may be that you do not want to display all messages on a particular operating unit in order to avoid a torrent of messages, for example. In that case, specific messages could be displayed just on a control desk, for example. In order to be able to control the display of messages so selectively, in STEP 7 each message can be assigned what is termed a display class. In all, there are 16 display classes (display classes 0 to 15). Example: Messages that are to appear on the machine might be assigned display class 1, those that are to appear on the control desk, display class 2. The various operating units then only analyze those messages that belong to specific display classes. Any other ALARM_S messages are immediately discarded.

Specifying display classes The display class to which an ALARM_S message belongs is determined when the message is configured in STEP 7. For a precise description of the procedure, please consult the information on message configuration in your STEP 7 documentation. If you do not specify a display class in STEP 7 the message concerned is automatically assigned to display class 0.

Selecting display classes In ProTool you must specify which display classes are to be displayed on the operating unit being configured. You make your selection by choosing System → Messages → Settings. You can find a precise description in the chapter called Setting the message procedure and selecting the display classes (Chapter 5.10.4). If you do not make a selection, all display classes (display classes 0 to 15) are displayed as the default.

In this dialog box you can set, individually for each PLC on your system, the messages to be displayed on the operating unit. By default, all messages are sent.

Tip By deliberately selecting certain messages you can restrict the display on the configured operating unit to certain display classes, in other words, to very particular messages. Other messages can then be displayed on another device, such as a control desk. The lefthand column of the dialog box shows you a list of all the PLCs on your system. For each PLC you can cause the operating unit to display no messages, a selection of messages or all messages. When you select the Details button, the Display Classes dialog box opens.

Note Messages of the Reporting system errors type are always displayed on the operating unit, however many display classes are selected.

5.10.5

Configuring ALARM_S messages

Configuring messages in STEP 7 ALARM_S messages are always configured in STEP 7 rather than in ProTool. The advantage of this is that you can use the messages on different display units but only have to enter them once.

5-58

ProTool User’s Guide Release 12/99

Configuration techniques

When configuring messages in STEP 7 you can either enter simple unformatted text or make use of the facility for device-specific message configuration. Depending on the display unit in question, you can then specify such effects as flashing text and define additional information. The following facilities are available for configuring ALARM_S messages in STEP 7: • Configuration using S7-PDIAG • Configuration in S7Graph or HiGraph • Call these via SFC17, SFC18 Note Graphics display devices do not support tags with text lists which you can configure in STEP 7 under Reporting system errors. You can find detailed reference information about the procedure in the online Help on STEP 7 and in the relevant option packages.

5.10.6

Incorporating ALARM_S messages When configuring messages in STEP 7 the message text and attributes entered are stored in the database shared with ProTool. During the process of compiling the project, ProTool automatically imports the necessary data and subsequently downloads it to the operating unit.

shared database

5.10.7

Updating the operating unit Since the S7-CPU stores the message information when a fault occurs, individual network stations (e.g. an OP) can log on at a later date and obtain an update. However, the S7-CPU only stores information about pending messages. Once all events (arrival, departure, acknowledgement) have occurred, the message is deleted from the CPU. When obtaining an update, therefore, the operating unit processes any missing events automatically if a message is not known to the PLC but the arrival and acknowledgement events are not entered on the operating unit. The events are not entered in the message buffer in that case, however. Events processed in this way are identified on the operating unit by displaying the message status symbols in inverse type thus:

*1234567 A KGQ HH:MM:SS DD.MM.YYYY GRU00 Boiler 13: temperature 190 degrees Inform shift supervisor Tel. 007 Automatically processed events

5.10.8

Use of resources ALARM_S messages are configured in STEP 7. The data is then stored in a shared database, imported during the process of compiling the ProTool project and finally downloaded to the operating unit. That means that ALARM_S messages use up resources on the operating unit. The shorter the messages are, the less storage space they will require. It is of no consequence in this regard which message procedure is used. More detailed instructions can be found in the section called System limits (Chapter I). The appendix contains information about the memory requirement of configurations, on the basis of which you can assess whether or not the memory of your operating unit is large enough for the intended configuration. Note In STEP 7 there are restrictions regarding the number and size of tags that can be used within a message. For more precise details, please consult your STEP 7 documentation.

Logging On For ALARM_S More than one station (e.g. more than one OP, PU, etc.) on a network can log on for ALARM_S messages. Each station that wants to display ALARM_S messages logs on to the CPU for ALARM_S. S7

MPI network

When a message event occurs When a message-triggering event occurs, the CPU actively sends telegrams to that effect to all stations that have logged on. The message number identifies the corresponding message text that has previously been downloaded to the operating unit. This means that the CPU does not have to be actively scanned for messages by regular polling as was the case with the message bit procedure. The operating unit and network are completely relieved of that burden on the system.

Time stamp With the ALARM_S procedure, the time stamp is not issued by the operating unit but by the CPU. The messages are stored in chronological order on the basis of their time stamp in the message buffer on the operating unit – even if they originate from different CPUs.

Information stored The CPU stores not only the time of the message but also the status (arrived, departed, acknowledged) and any process parameters. That information is retained until a message has been completely processed, i.e. until it has arrived, departed and been acknowledged. On the operating unit, the information in the message buffer is kept even longer.

5.10.10

Acknowledging ALARM_S messages

ALARM_S messages requiring acknowledgement When a message is acknowledged by a station on the network, the CPU is immediately notified. The CPU then distributes the acknowledgement to all connected stations. It is only to this message that the operating unit responds, i.e. only at this point does it enter the acknowledgement in the message buffer.

Note The CPU issues a time stamp for the acknowledgement event but does not store it. When a subsequent update is made, therefore, it is no longer possible to establish whether and when a message was acknowledged (see Updating the operating unit).

ALARM_S messages not requiring acknowledgement Certain ALARM_S messages are configured as alarm messages but do not require explicit acknowledgement by the user; the CPU acknowledges such a message automatically when it arrives.

5.10.11

Printing ALARM_S messages You specify which messages are to be output to a printer in the usual way in ProTool by choosing the menu option System → Messages → Settings.

Message Logging If you do not specify any device-specific message settings in STEP 7 (refer to Configuring ALARM_S messages), all message events are automatically logged directly to the connected printer. If you configure device-specific messages, you can specify separately for each message whether it is to be logged or not. Messages are always printed in the order in which they are sent by the CPUs. This is also the case with every synchronisation.

Remark If there are several CPUs in a network, this means that messages need not always be received in chronological order by the operating unit.

Using functions

Overview Functions are a central element of configuration with ProTool. This section explains what functions are and how to use them in practice.

5.11.1

What functions are used for

Basic principle In ProTool, you can link events (e. g. "Key pressed") with predefined functions. If the event occurs during operation, the function executes a specific action on the operating unit or the PLC. For example, the "Select Screen" function on the operating unit opens a particular configuration screen.

Event Press key

Function: Select Screen

A

B

Action: Screen is switched Triggering a function

Areas of application In general, you can use functions to: •

Set up the configuration process-specifically (e.g. to switch from one screen to another)

ProTool User’s Guide Release 12/99

5-63

Configuration techniques

•

Control the process (e.g. to set a bit in order to switch on a motor with it)

•

Use features of the operating unit (e.g. to display or print out the message buffer)

•

Perform system settings online on the operating unit (for example, change modes)

In most cases, you can configure the behavior of the functions precisely by means of parameters. If you want to trigger several actions, you can also combine different functions.

Configuration You configure functions on the Functions tab in the properties dialog box of the relevant object. For some operating units you can also define global entry points by choosing the System → Functions menu command.

5.11.2

Events for triggering functions

Necessity The execution of a function is always linked to a specific event. The function is only triggered when this event occurs. The events that can be linked to a function depend on the type of the function. Many functions are only effective with certain specific events.

Examples Examples of events that can trigger functions are the events "press key" and "release key". In the case of the former, the function is executed the moment a particular function key is pressed; in the latter case, it is executed the moment the function key is released again.

Object-linked functions Functions and events are generally linked to a specific object. For example, a function linked to the event "press key" is to be triggered when a specific key is pressed, not just any key.

5-64

ProTool User’s Guide Release 12/99

Configuration techniques

The following objects can be linked to functions, for example: •

Function keys, soft keys and buttons

•

Screen objects

•

Screens

•

Tags

Depending on the operating unit, it may not be possible to configure functions for all these objects. Tip Functions with tags are triggered only if the Read Options Continuously tab is selected or the tag is displayed on the screen.

Global functions You can also link some functions to global, object-independent events. These can be triggered in cases such as the following: •

when a tag is initialized or upon system startup

•

when a value is entered

•

when a screen shot is printed (Print Screen)

•

when the message buffer overflows or is deleted

•

when a data record of a recipe is read or written

Depending on the operating unit, it may not be possible to configure all events. You will find a detailed description of all the permissible events in the ProTool online Help under the topic Configurable events.

5.11.3

Function parameters

Necessity Many functions can only execute one particular action. For example, the Events - Delete Buffer function empties the buffer for event messages.

Configuration techniques

Function

predefined action

Function without input parameters

However, many functions can also work in various ways.

Input parameters Imagine that you want to open another screen using a key on the operating unit. To do this, you configure the Select Screen function. However, your project will generally have several screens. Which of these screens should ProTool open? You therefore have to give the function more information. This is done using parameters. For the Select Screen function, you specify as a parameter the name of the screen to be opened, for example. Another example is the Language function. In this case, the parameter you specify is the language to be set.

Input parameters

Function

Action depending on input parameter

Function with input parameters

Some functions require a single parameter; others require several.

Output parameters Some functions write the result of their execution (i.e. the current status) to a tag. You can then further evaluate the value of this tag, for example in order to display a setting-dependent text on the operating unit. An example is the Mode function. You specify a code for the operating mode as the input parameter, and the function supplies the same code in a tag as the output value. The value of the tag lets you display the current operating mode by means of a text list, for example.

Note Output parameters cannot be configured for all operating units.

Input parameters

Evaluation (optional)

Function with input and output parameters

Special case: program-controlled behavior In the case described above, the behavior of the functions does not change during runtime. However, in the case of some operating units and some functions, you can also pass the value of a tag as an input parameter. The behavior of the function can thus be controlled by the program.

General principle The following figure illustrates the principle of how a function works:

Tag Function

Tag

Constant

How a function works

An input parameter is specified for the function. This can be either constant or read from a tag. The tag may be local or it may have a connection to the PLC. If there is a connection to the PLC, the value is set by the process. The result of the function is written to a tag, which itself can either be local or have a connection to the PLC.

5.11.4

Combining multiple functions

Multiple functions with one object You can also assign an event several functions. The functions are then initiated one after the other. You set the order in which this occurs in the Functions dialog box during configuration. You can change the order of the functions by using the Up and Down buttons.

Multiple functions with one object

Sequence The list of functions is processed from the top down. Note On account of the differing runtimes of the functions, the start of the next function in the list is not linked to the completion of the function preceding it in the list. Thus, it can happen that several functions are being executed concurrently and the result of a previous function is not yet available.

Buttons with fixed functions When you configure a touch panel, ProTool offers a selection of different buttons that are already assigned frequently used functions: •

Set/Reset Bit and Set/Reset Bit in Word

•

Select Screen

•

Light Indicator

You will find detailed information on this in the topic What are buttons. (Chapter 5.3.6) Note As with any other operating unit, instead of using these buttons you can use a normal button and configure the function you require manually.

5.11.6

Displaying and setting date/time The date and time are displayed and changed using functions on the operating unit. There is a function available for Date Display/Edit and a function for Time Display/Edit in each case. Configure these functions with tags that do not have a connection to the PLC. You can only use one tag to which the date or time are linked in each project. If you use more than one tag for this, they are not updated when the date and time are set or changed.

Weekday You can set the current date and time in a standard screen on the operating unit. In contrast, you can only set and read the day of the week by means of PLC job no. 15. Before it is read for the first time, the day of the week must be set by means of a PLC job. You will find a list of all the PLC jobs in the ProTool online help system.

Objective You want to set the Online and Offline operating modes by means of two function keys. The text "Online Mode" or "Offline Mode" is to appear on the operating unit.

How to configure the functions 1. Create and open the screen in which the switchover and display take place. 2. Click the function key that you want to use to switch on the Online operating mode. The Function Key dialog box appears. 3. Select the Functions tab. 4. Select the Display Selectable Functions check box. The Select Function window appears. 5. Select the Mode function under the Switch function group.

6. Click the Add button. The Parameters dialog box appears. 7. Select the Operating Mode (Key) parameter from the list, and enter the value 0 in the input field under the list. This parameter controls the behavior of the Mode function, so the mode changes to online. 8. Select the Operating Mode (Field) parameter from the list. Here you specify a tag to which ProTool assigns the value of the current operating mode at runtime (0 for online mode, 1 for offline mode). This tag subsequently controls the display.

how to transfer data records between the operating unit and the PLC.

What is a recipe?

Purpose The purpose of recipes is to transfer a group of related data to the PLC together and synchronously.

Recipe and data record The terms recipe and data record are defined below using the example of a filling station for a fruit juice system:

Fruit juice system

•

Recipe Recipes correspond to the drawers of the filing cabinet shown (for example Orange or Lemon). The reference value fields (tags) that belong to the recipe are defined in the recipe. You use the recipe to define the data structure in your ProTool project. You cannot change this structure subsequently on the operating unit. You can configure up to 255 recipes in ProTool. • Data record Data records correspond to the filing cards in the drawers of the cabinet (Drink, Juice and Nectar). A data record contains the values for a recipe. You create, delete and modify data records on the operating unit. You can configure up to 500 data records for a recipe.

Example of a recipe The filling station above is used to produce orange drink, orange juice and orange nectar. The mixing proportions for each of these are different. The ingredients are always the same. Let us assume that a recipe called Mixture is created, containing, for example, the following data structure: Tag

Designation

Var_23

Name

Var_11

l orange

Var_7

l water

Var_19

kg sugar

Var_21

g flavor

The tag designations Name, l orange, g flavor etc., are known as entry names. The entry names are displayed as well on the operating unit. Tag Var_11, for example, can thus be identifed as the tag designating the mixture component orange. The data records contain the values for the different drink types. The data records could be as follows, for example: Orange drink

Orange juice

Orange nectar

Same tags in screens and the recipe For each ingredient (orange, water, etc.) there is a separate screen in the above example, containing a supply tank, valves, an overview of the quantities used and other information. The screens contain input fields that allow you to set the various supply quantities for the mixer. You can thus enter the mixing proportions screen by screen. The mixer is then started. This process is repeated for each drink type. If the tags of the input fields are formed into a recipe, you can store finished mixtures for the different drink types by creating data records on the operating unit. The figure below shows how to use the same tags in screens and in the recipe. To produce a specific drink type, the corresponding data record is transferred to the PLC. All tags are thus assigned the required values at the same time. Mixer Scr_1

Configuration techniques

Note If you use a tag in a recipe that is also assigned to an output field in the screen, the PLC may overwrite the current value. This situation occurs, for example, when data records are transferred from the data medium to the PLC. The tags are updated in the operating unit, and the values are then transferred to the PLC. In the meantime, however, the PLC could have updated the output field tag. In this case, the value of the PLC is transferred, not the value of the data record.

For how to configure a recipe, see Configuring recipes (Chapter 5.12.2).

•

For how to transfer data records, see Transferring data records (Chapter 5.12.3).

Configuring recipes

Identifying a recipe on the operating unit You create a recipe in your project with a symbolic name. You also use this symbolic name to select the recipe on the operating unit. The recipe also receives a number, but this is only valid during configuration. You can change the recipe’s name and number. In the project window, open the Recipe dialog box by means of a double-click, and then click the Properties button.

Identifying the recipe on the PLC Three identifiers are available for identifying recipes on the PLC. You enter the identifiers on the Options tab in the Recipe dialog box. The identifiers are userdefinable. ProTool automatically enters the number of the recipe in the first identifier. The identifiers are written to the data mailbox when a data record is transferred from the operating unit to the PLC and can be evaluated by the PLC.

Identifying a data record You create a data record on the operating unit with a symbolic name. This name is only relevant on the operating unit. When a data record is transferred, only the data and the identifiers of the recipe are transferred. Apart from the identification of the recipe, the PLC has no special way of identifying the data record. If you want to identify the data record on the PLC, you create in the recipe a tag that contains the name of the data record.

ProTool User’s Guide Release 12/99

5-79

Configuration techniques

Tags in recipes Tags that you use in recipes must have an address on the PLC and the attribute Write Directly. Only these tags will be transferred to the PLC when a data record is transferred. Tags without an address are not transferred. You set the attributes on the Options tab in the Tag dialog box. There is no point using the tag types Timer and Counter in recipes.

Standard screens for recipes The standard screens Z_RECORD_1 and Z_RECORD_2 are available so that you can create, save and transfer data records on the operating unit. These screens exist in the standard project but are not yet integrated. Integrate the standard screens in your project by assigning the Select Screen function to a function key, for example. Specify the standard screen Z_RECORD_1 or Z_RECORD_2 as a parameter. If you want to use both standard screens, assign each one to a function key. You only need the Z_RECORD_2 standard screen if you want to transfer current data directly between the operating unit and the PLC.

Text or graphic list for recipes When you create the first recipe, a text or graphic list with the designation Z_RECIPES is created automatically. This text or graphic list is used in the supplied standard screens for data records. The sequence in which the recipes are entered in the text or graphic list is determined by the recipe numbers. You also see this sequence on the operating unit when you select a recipe.

Data mailbox To transfer data records, you must set up a data mailbox on the PLC and specify it in your project by choosing System → Area Pointers. The operating unit writes the identifiers and the length of the data record to the data mailbox. The data mailbox must therefore be at least five words long. The figure below shows its structure. 1st word nd

Defining the structure of a recipe When you have completed your project, you should define the structure of the recipe. To do this, click the Properties button in the Recipe dialog box. When you define the structure, you write-protect the recipe. This imposes restrictions on the changes you can make to the structure. Tags can still be deleted, but this leaves gaps in the structure. You can only add new tags at the end of the structure. If you define the structure of the recipe, you can continue to use data records that you created on the operating unit.

Using symbols If you also save the symbolic names of the tags in the data record when you create data records, you can still load data records on the operating unit after a change to the recipe structure. To do this, click the Properties button in the Recipe dialog box and select the Use Symbols check box. If you do not select the Use Symbols check box, only the values are saved. The symbolic names of the tags are not saved in the data record. If the recipe structure is changed subsequently, values are interpreted incorrectly.

5.12.3

Transferring data records Note When data records are transferred from the data medium to the PLC, the data is initially written to the tags in the working memory of the operating unit. From there it is written to the PLC. If you have configured the attribute Read Continuously for the tags to be transferred, or if the tags are configured as actual values in the current screen, it may be possible for the tags to be overwritten with current values. In this case, it is not the data read that has been read that is transferred from the data medium to the PLC; instead, is the data that has been updated in the meantime. How to create data records and transfer them to the PLC is described in detail in the manual of your operating unit.

Transferring data records when working on the operating unit (standard case) The transfer of data records from the operating unit to the PLC and vice versa is the standard case. The special cases are described in the Communication User’s Manual. We recommend that you only transfer data records by using the operating unit. To do this, use the standard screen Z_RECORD_1.

ProTool User’s Guide Release 12/99

Configuration techniques

•

Setting the transfer mode The selection of the transfer mode depends on the operating unit and the PLC used: − Direct transfer: When a data record is written, the tags of the data record are written directly to the defined addresses. In direct reading, the tags are transferred from the system memory of the PLC to the operating unit. − Indirect transfer: All the tags of the data record are written to the PLC’s clipboard. Set the direct transfer mode.

•

Creating data records Data records can only be created on the operating unit and saved on a data medium there. The data medium that can be used depends on the operating unit. The Z_MEMORY text and graphic list is used in the Z_RECORD_1 standard screen. This contains the assignment of data medium and value: 0: Flash 1: Module 2: Floppy disk

•

Synchronization during transfer An essential feature of recipes is that the data is transferred with synchronization and uncontrolled overwriting of the data is thus prevented. In order to ensure coordinated operation when data records are transferred, bits are set in the control and acknowledgment area of the interface area. The interface area for the SIMATIC PLCs is described in the Communication User’s Manual. You will find information for non-SIMATIC PLCs in the ProTool online help system.

Transferring data records by means of a PLC program •

PLC job You can transfer data records from the PLC to the operating unit and vice versa by means of PLC jobs 69 and 70. However, the PLC job only writes to the tags or reads from them. The data record cannot be saved on the data medium or read from the data medium directly using a PLC job. You have to use the operating unit for this.

•

Function ProTool offers functions for: − Reading data records from the PLC and saving them on the data medium using the operating unit

− Reading data records from the data medium and transferring them to the PLC Assign a function like this to a tag. The parameters of the function contain recipe names and data record names. Assign the parameters of the function initially from the PLC. If the value of the tag is changed by the PLC, the function is triggered.

Example: How to create a recipe

Task In this example you create a recipe for the mixing station of a fruit juice system. Different fruit juices are to be mixed using the same system. The ingredients are the same; only the mixing proportions are different. You begin by creating a recipe called Mixture and then a data record with the name Orange. This data record contains the mixing proportions for orange juice. The data record is transferred indirectly (in other words, the data is written to the data mailbox). During transfer of the data record, the operating unit sets bits in the control and acknowledgment area. You then have to set and reset bits in the PLC program in order to release the data mailbox again. The task involves the following steps: •

Creating a recipe

•

Integrating standard screens

•

Transferring a project file to the operating unit

•

Creating a data record on the operating unit

•

Transferring a data record to the PLC

Example system You are going to create the example recipe for an OP37 linked to the SIMATIC S5 PLC via AS511. The PLC is the AG115U with the CPU 944. Preparatory settings: 1. Open the standard project OP37_S5.pdb. Save the project with a new name (for example QUICKMIX.PDB) by choosing File → Save As. 2. In the project window, select PLCs and double-click the entry in the right column. To change the CPU type, click the Parameters button in the PLC dialog box. Select the CPU type S5 115U CPU944 and close all the dialog boxes.

Configuration techniques

Creating a recipe: 1. In the project window, double-click Recipes to create the recipe described below. 2. Create the new tag Var_23 for the data record name. Type: KC Length: 4 bytes. Set an address for the tag on the PLC, for example DB 12, DW 0. Do not change the PLC that is set. You can thus also use the tag in screens or messages. Do not change the attributes of the tag, since these already have the correct settings for recipes. 3. Give the tag the entry name Name in the Recipe dialog box. Add the entry to the recipe structure by clicking the Add button. 4. Create four more tags - Var_11, Var_7, Var_19 and Var_21 - for the mixture ingredients orange (in liters), water (in liters), sugar (in kilograms) and flavor (in grams) with the following settings: Type: KF Length: 2 bytes. Specify DB 12 for the address as well. Configure 1 decimal place for tag Var_19 (sugar). In the Recipe dialog box, give the tags the entry names shown and add the entries to the recipe structure. You define the structure of the recipe by means of the order of the tags.

The value for Length represents the length in bytes. The value for Offset (in bytes) sets the position in the structure. If you add its length to the offset of the last entry, you get the total length of the data record. Additional settings: In the following steps you change the name of the recipe, set identifiers and transfer mode and set up the data mailbox. 5. Click the Properties button in the Recipe dialog box. Change the name of the recipe in Mixture. Freeze the structure of the recipe. To do this, select the Set check box under Structure.

Check the settings on the Options tab. Transfer: Direct Identifiers: 1 / 0 / 0 6. Close the dialog box. All the entries in the recipe then appear in gray. When you create the first recipe, ProTool automatically creates a text or graphic list with the name Z_RECIPES. This text or graphic list is used automatically in the Z_RECORD_1 and Z_RECORD_2 screens. You do not have to make any further settings for this. 7. Choose System → Area Pointers to set the interface area. Click the Add button, and set the address: Area: DB.DW DB: 51 Length: 185 Set up the data mailbox: Area: DB.DW DB: 14 Length: 5 Create data block 14 with a length of at least 5 data words in your PLC program as well. Integrating standard screens: In the following steps you integrate the standard screens in your project so that you can use them on the OP37. 1. Create a new screen. Choose the Edit → Properties menu command. On the General tab, select the Start Screen check box. Give the screen the name Start. 2. Assign the selection of standard screens to the F13 key. To do this, click the F13 key. Select the Select Screen function under Screens. Click the Add button, and select the standard screen Z_SYSTEM_MEN under Screen Name. Use a drawing program (for example, Paint) to create an icon containing the text Standard. 3. Assign key F15 the standard screen call Z_RECORD_1. Create an icon for this containing the text DAT_1. 4. Open screen Z_RECORD_1. Assign the Start screen call to key F20. Create an icon for this containing the text ESC. Transferring a project file to the operating unit: 1. Choose File → Save to save your project. 2. Connect the OP37 to the configuration computer using the connecting cable. 3. Choose File → Compile to compile an executable project file.

Configuration techniques

The example describes the individual configuration steps required to enable data records to be transferred from the operating unit to the PLC. To do this, you associate the DAT → OP/PLC function with a tag. For the parameters of the function you use tags already used in the standard screen Z_Record_1. You proceed in an analogous manner to that described above when you want to transfer data records in the opposite direction (i.e. from the PLC to the operating unit). 1. Create an integer tag with the symbolic name VAR_212. Establish a connection to the PLC. 2. In the Tag dialog box on the Options tab, select the Read Continuously check box. If you do not do this, the operating unit will not detect it when the value of the tag changes. 3. Change to the Functions tab. Under Data Record in the Select Function dialog box, select the DAT → OP/PLC function. 4. Click the Add button to add the function to the Selected Functions field. 5. Set the function parameters. To do this, select the individual parameters one after the other and assign the tags shown:

6. In order to be able to write to the tags from the PLC, they must have a connection to the PLC. To do this, configure an address on the PLC for all the tags specified for step 5. In addition, on the Options tab, assign the attribute Read Continuously for all the tags. 7. Now trigger the function. To do this, on the PLC, assign to the following tags the name of the recipe and of the data record that you want to transfer from the operating unit to the PLC: Z_MEMORY Z_DATRNAME Z_DATRINFO Z_RECIPE Specify the data medium as well. The comment is optional. 8. Change the value of the VAR_212 tag on the PLC. This triggers the function associated with the tag. The data record is transferred from the operating unit to the PLC.

Operator guidance

Purpose In addition to the option of customizing the user interface of your operating unit to make it easier for you to use, ProTool features other options for supporting and prompting you on your operating unit as a function of the situation. This means you can implement mechanisms and decision-making aids that can prevent possible incorrect operations on the operating unit.

Overview ProTool makes the following methods available for the implementation of operator prompting: • Providing Help text (Chapter 5.13.1) • Assigning icons to local function keys (Chapter 5.13.2) • Showing/hiding operating and display elements (Hiding an object (Chapter 5.13.3)) • Applying dynamic attributes (What are dynamic attributes? (Chapter 5.13.4)) • Evaluating key operation (Chapter 5.13.5) • Driving light-emitting diodes (Chapter 5.13.6)

5.13.1

Providing Help text Help text provides additional information and operator instructions on screens, input and output fields and messages to the operator at runtime. For example, Help text may be in the form of the permissible range of values for an input field or the cause and elimination of a malfunction in the case of an alarm message. Configure information for objects on the Help Text tab. Configured Help text is displayed in the language set on the operating unit by pressing the Help key.

5.13.2

Assigning icons to local function keys Icons are fixed-size pixel graphics that are placed in the immediate vicinity of screen-specific function keys (soft keys). This means that you can illustrate the function of a locally assigned function key. You can prevent inadvertent, incorrect operation of a key to a large extent by means of an informative symbol.

ProTool User’s Guide Release 12/99

5-89

Configuration techniques

5.13.3

Hiding objects

Purpose ProTool features an option of displaying and hiding control and display elements in runtime. For example, you can hide an output field on the operating unit when the actual value is within the specified setpoint range. Alternatively, display an input field only when an operator input is expected for the control in a specific situation – for example, during startup. The user interface of your operating unit remains neat and tidy in this manner.

Index tag You can either link display and hiding to a constant range of values or to the tag of an input/output field, for instance. You can influence several input/output fields simultaneously by using a separate tag. If you assign a password level to the tag, you can display control or display elements only for a specifically defined group of users.

5.13.4

What are dynamic attributes?

Purpose To draw the operator's attention on the operating unit to specific situations – for example, specified limit values have been reached or exceeded – you can configure attributes for input and output elements. This means that you can dynamically modify the foreground and background colors, for example, of an input/output field at runtime as a function of the value of a tag, or you can enable or disable flashing for the text that is being displayed.

Index tag You can either link the specified attributed directly to the tag of an input/output field, for instance, or you can define a separate index tag for it. You can influence several input/output fields simultaneously with a separate index tag.

5.13.5

Evaluating key operation

Purpose Key operations on the operating unit can be downloaded to and evaluated on the PLC. This means, for example, that you can issue a message that will draw the operator’s attention to the incorrect operation of a key.

Requirements For the PLC to be able to evaluate whether and, possibly, which key has been operated on the operating unit, you have to create specific data areas on the PLC and specify them in your project at System → Area Pointers. These are the two data areas System keyboard assignment and Function keyboard assignment, depending on which keys you wish to evaluate. You set the assignment of the function keys to the bits in the function keyboard assignment when you configure the function keys. You will find a description of the keyboard assignments for the different operating units in the Communication Manual.

5.13.6

Driving light-emitting diodes

Purpose The light-emitting diodes (LEDs) on the function keys of the operator panel can be driven on the PLC. By means of a light-emitting or flashing LED, you can indicate to the operator that, for example, the operating panel is expecting a certain function key to be operated.

Requirements For the PLC to be able to drive the LEDs, you have to create the LED assignment data area on the PLC and in your project by choosing System → Area Pointers from the menu. Set the assignment of the individual LEDs to the bits in the LED assignment when you configure the function keys. You will find a description of the LED assignment and the LED functions for the different operating units in the Communication Manual.

5.13.7

Assigning operator authorization

Purpose ProTool allows you to use a password to prevent controls such as input fields and function keys from being used by those unauthorized to do so. This means that when you are creating your project you can restrict the use of functions that relate to security to specific people or groups of operators. Important parameters and settings can thus only be changed by authorized personnel. The access protection that you configure allows you to guard against incorrect usage and increase the security of the system or machine.

Password hierarchy During the configuration phase you can assign operator authorization to specific groups. At runtime, individuals can be allocated to one of these groups, as appropriate, and they thus automatically receive the access rights of that group. ProTool provides hierarchically organized password levels from level 0 to 9. If a user is assigned password level 4, for example, this user is authorized to execute the functions of password levels 0 to 4. •

Password level 0 Password level 0 is the default in ProTool. Use this lowest level in the hierarchy for functions that have little or no effect on the operational sequence. These are generally functions that do not required any input, such as the display of messages. You do not have to enter a password on the operating unit in order to execute functions with password level 0.

•

Password levels 1 to 8 Assign functions to password levels 1 to 8 according to their importance. Before you execute these functions, the operating unit prompts you to enter a password.

•

Password level 9 The authorization to execute functions at password level 9 is granted only to the System Administrator or service engineer. This provides access to all the functions of the operating unit, including password administration. You define the password of the System Administrator by choosing System → Settings. The default setting is 100. You can change this setting on the operating unit at runtime.

You can find more information on password administration in the equipment manual for your operating unit.

Logging into and out of the operating unit •

When you call a password-protected operation, the operating unit automatically prompts you to enter an appropriate password. In order to eliminate the possibility of those without authorization gaining access, a password level greater than 0 should not remain active on the operating unit for any length of time.

•

If you do not do anything on the operating unit for a configured period of time (logout time), the operating unit automatically resets the current password level to 0. You set the logout time by choosing System → Settings. The system preset is 5 minutes.

Note To log into the operating unit, use the Z_PASSWORD standard screen in your project.

Setting the password level on the operating unit The following PLC jobs are available for setting a defined password level on the operating unit: •

PLC job 23 allows you to set any password level on the operating unit from the PLC, for example in order to allow a defined user group to use the operating unit.

•

PLC job 24 allows you to reset the password level to 0 from the PLC.

You will find a list of all the possible PLC jobs with job numbers and parameters in the ProTool online help system.

Configuration in foreign languages

Overview This chapter shows you what you need to know in order to create a project with a user interface in a foreign language. You can create a monolingual or a multilingual project. In a multilingual project you can decide:

5.14.1

•

whether to make several languages available on an OP and provide the user with a key for switching between them

•

whether to download only one language to a specific OP

System requirements for foreign languages Depending on your Windows language, you can configure nearly all foreign languages without having to perform changes to you Windows configuration. The exceptions are languages with special character sets such as Greek, Polish, Russian, Slovenian, Czech and Hungarian. To be able to use these languages, you have to enable language support under Windows 95 (Control Panel → Software → Windows Setup → Language Support → Details). This is not necessary in Windows NT. Alternatively, you can install Windows completely in one of these languages, of course. Note The ProTool installation CD-ROM contains support for other languages not supplied as standard with Windows such as Albanian, Bulgarian, Romanian, Turkish, etc. in the directory WINLANGS. More detailed information is provided in the file MULLANGO.INF. To create projects in Asiatic languages, you require an Asiatic Windows system in any case. You will find further information about this under the keyword Requirements for configuring in Asiatic languages (Chapter 5.14.8).

User interface language and project languages

User interface language and project language Basically, a distinction has to be made between two different display levels: •

ProTool’s user interface language. This is the language in which text is displayed on menus and dialog boxes in ProTool. The user interface language is selected in ProTool’s Setup.

•

The project language for the operating units. This is the language in which configured text appears on the operating unit. The configuration can be created in all of the languages available on the configuration computer under Windows. The following objects contain language dependent text: − event messages − alarm messages − screens − recipes − text lists − help texts

The two language levels are completely independent of each other. For example, you can create French projects with an English ProTool, or English projects with a French ProTool.

Configuration techniques

Up to three project languages per operating unit You can store text for any project in as many project languages as you like. You can even download up to three of these project languages simultaneously to an operating unit. The operator can switch from one language to another. To do this, you configure the function Language.

Editing language The project language in which you edit text at any given time on the configuration computer is the editing language. The toolbar and the status bar show the current editing language setting.

Reference language One of the project languages can be used as the reference language. You can create all the different pieces of text in the reference language first and then use it as a basis for translations into other languages.

5.14.3

Configurable languages

Basic requirements With ProTool you can configure all languages using Latin characters, as well as Russian and some of the Asiatic languages. You first have to load many of the languages in Windows, however, or you have to install Windows in a different language (refer to System requirements for foreign languages (Chapter 5.14.1)).

Standard projects The most frequently used languages have been preselected in the standard projects supplied with ProTool: • German • English • French • Italian • Spanish • Chinese (PRC) • Chinese (Taiwan) • Korean

5-96

ProTool User’s Guide Release 12/99

Should you wish to configure another language, you have to add it yourself and also translate the pieces of text in the standard projects.

System messages System messages for your operating unit are available in the following languages: •

Chinese (PRC)

When you configure another language, all the system messages appear in English. You cannot edit system messages in ProTool.

5.14.4

Language dependent fonts In ProTool you can select four different character sets by choosing System → Character Sets from the menu, and these are available to you on every screen: •

one language independent character set

•

three language dependent character sets

ProTool User’s Guide Release 12/99

5-97

Configuration techniques

Setting language dependent character sets

The language independent character set is available in all languages. The language independent character set is the default symbol. The symbol set is used for character graphics. The character sets have to be a fixed-pitch font. This means that each letter is the same width. In the case of proportional font, on the other hand, different letters have different widths: The letter ”i” needs less space than the letter "w", for instance. The language dependent character sets may vary from language to language. This is always necessary when certain language dependent special characters are not contained in the ANSI code. The language dependent character sets change automatically:

5.14.5

•

when you change the editing language in ProTool

•

when the operator changes from one language to another on the operating unit

Language dependent keyboard assignment

Language dependence The characters on a PC keyboard are language dependent. For example, no German or French special characters are available on an English keyboard. Further, the letters are arranged somewhat differently. As soon as you change the editing language in ProTool, it modifies the assignment of your keyboard to the layout of the foreign language concerned.

5-98

ProTool User’s Guide Release 12/99

Configuration techniques

Auxiliary window with keyboard layout In order to facilitate the assignment of the characters printed on your keyboard and those actually entered, ProTool displays a window containing the new key layout on the screen. You can then see where differing keys are located and can enter them directly. Alternatively, you can directly click the different letters and special characters on the screen with the mouse.

Example of language dependent keyboard with French as the editing language

The language dependent keyboard is hidden automatically as soon as you change the editing language back to the current Windows language. You can also activate and deactivate display of the language dependent keyboard by choosing View → Keyboard.

5.14.6

Reference text When you create a project for several languages, you normally configure all the pieces of text in your native tongue first. If you then change the editing language to enter text in a foreign language, all the text fields appear blank again. ProTool features a user-friendly reference text function so that you have a basis for your translations. In dialog boxes, you can view the original text in the reference language by clicking a special button. You can display an additional window with reference text in the screen editors by means of the toolbar or by choosing View → Reference Text.

Steps to creating a multilingual project

Scenarios The basic approach is identical no matter whether: •

you configure in a different language from that installed in ProTool. (Example: you have ProTool in German and would like to create a French project.)

•

you want to sell a project to several countries, in the language of the countries concerned. (Example: you are sending a machine to Germany, England and France. You want all pieces of text to be displayed on the operating unit in the language of the countries concerned.)

•

you supply a project to a multilingual country. (Example: you are selling a machine to Switzerland. You want the operator to be able to choose between German, French and Italian on the operating unit.)

5-100

ProTool User’s Guide Release 12/99

Configuration techniques

In any case, you should always attempt to create and test the project in one language first. This language then acts as your reference language for the translations.

Steps Configuring in foreign languages consists of the following specific work steps: 1. Comply with the requisite system requirements. 2. Define the languages you want to configure (choose System → Language Assignment from the menu). 3. Select a language as the first editing language (choose Edit → Languages from the menu). Create and test the complete project in this language first before proceeding to translate all the pieces of text later together. 4. Setting up the character set (menu item System → Fonts) 5. Configure a language change (only when you want to offer several languages simultaneously on one operating unit). 6. Translate the pieces of text. To translate them, change the editing language (choose Edit → Languages). Select the language in which you created the project as the reference language (likewise choose Edit → Languages from the menu). 7. Select the languages to be downloaded to a specific operating unit (choose System → Language Assignment from the menu). You can select a single language but, alternatively, you can select up to three languages simultaneously. 8. Compiling the project. 9. Download the project to the operating unit. Detailed descriptions of the different steps will be found in ProTool online Help. Note Avoid moving fields in event messages and alarm messages when you modify a configuration that has been created in several languages. Since there is no permanent assignment between the field and its position within the text, you should move the pieces of text – if necessary – instead of the fields.

5.14.8

Requirements for configuring in Chinese

Asiatic Windows system A requirement for creating a project containing Asiatic text is an Asiatic Windows system, because the requisite character sets can be accessed only on Asiatic Windows systems. To assist you with entering Asiatic characters, the "Input Method Editor" (IME) is available on such systems, and you can use it to define text as phonetic transliterations, for example. ProTool’s virtual keyboard is therefore not made available. Even the compilation must be carried out on an Asiatic Windows system, otherwise the project language will be ignored during compilation. Under certain conditions, it is possible to download projects in which an Asiatic project language has been selected, on a non-Asiatic Windows system. For this, the *.fud or *.fwd file created during compilation on an Asiatic Windows system has to be available in the same directory as the *.pdb project file. The *.pdb configuration file may only be opened before the download operation, but not modified any more.

Tip Many projects are multilingual and use, for example, English in addition to an Asiatic language. In such cases you can first create and test your project on a nonAsiatic Windows system. Not until it is completed do you change to an Asiatic system, on which you configure and compile the Asiatic text and perform the download operation. It is practical in these cases to have both an Asiatic and a non-Asiatic Windows system installed on your computer or to work on a network with different computers for the languages concerned.

5.14.9

Constraints with Chinese projects The languages Chinese (PRC), Chinese (Taiwan) and Korean are currently supported.

Configuration memory Use different character sets as sparingly as possible in a project. Every character set you use reduces the amount of memory available for projects. Every font size you load is a separate character set.

5-102

ProTool User’s Guide Release 12/99

Configuration techniques

64 kB of configuration memory are available per character set, which approximates to 1900 different Chinese characters, for example. If you configure more Chinese characters, you obtain an error message during compilation to the effect that the maximum number of characters has been exceeded. At the same time, a list of the most infrequently used characters in the configuration is output.

Special characters Special characters are ASCII characters > 127 – for example, ã, ±, ä, è, ó. If you use a non-Chinese character set in text under an Asiatic Windows system, you should not configure any special characters, because they are not displayed correctly in the following cases: •

in text, input or output fields for the display of which on screens a non-Chinese character set has been chosen

•

for symbolic object names that are displayed, for example, in title bars

Non-Asiatic projects under Asiatic Windows NT If you create projects under an Asiatic Windows system for a non-Asiatic language – for example, German – it might not be possible to edit special characters in text contained in dialog boxes on account of an operating system error – for example, Help text or labeling on buttons. To avoid this problem, you have the following options: •

Use another non-Asiatic Windows system.

•

Edit your pieces of text in another application and then copy them to your ProTool project.

•

Adapt the registry: in the path HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FontAss oc\ AssociatedCharSet all codes have to be assigned the value "no". Restart Windows for these modifications to take effect.

Warning This modification may affect other applications and for that reason you should reset the codes in the Registry to their previous values upon completing your project.

Configuration techniques

Messages All system messages are also available in Asiatic languages. The message number, message status (Active, Cleared, Acknowledged), date/time and acknowledgement group remain single-byte characters in Asiatic configurations. Messages created with Asiatic characters cannot be exported or imported with ProTool.

Print jobs on the operating unit When using a symbolic language, all the print jobs are output in graphics mode to the operating unit printer.

Field length Field lengths depend on the width of the characters used. With Asiatic character sets, the number of configurable characters in fields can be reduced as a result of the double character width.

Standard projects Standard projects and examples are also available in Asiatic languages.

6.1

Testing projects Once you have completed your entire project or self-contained parts within it, the test phase comes. The following steps must be taken: 1. Compile the project - in other words, create a file from the project that can be run on the operating unit. 2. Download the project - in other words, transfer the project to the operating unit. You have to carry out some settings for this. 3. You test the project; If you find any errors, correct them and begin again with step 1.

Note If the PLC you are using is a SIMATIC S5 or S7, configure Status/Force in order to test certain tags in the PLC program, for example.

Downloading the executable project file

Basic procedure To download the project file, you have to do the following: 1. Set the transfer mode. 2. Select an interface on the configuration computer. 3. Select a storage medium on the operating unit. 4. Download the project file.

Peculiarities These deviations from the basic procedure are only to be carried out the first time: •

Transfer mode: The first download is always a serial transfer.

•

Firmware: Before a compiled project file can be downloaded to the operating unit for the first time, the firmware of the operating unit is downloaded automatically. A corresponding status message is issued.

Download not possible If no connection to the operating unit can be established, a status message to this effect is output. Check the physical connection between the operating unit and the configuration computer. Note The project file must not be transferred directly from the configuration computer to the module, but must first be loaded into the flash memory on the operating unit, since the memory organization of the two storage media differs. If the project file were to be downloaded directly to the module and then loaded into the flash memory on an operating unit, error states can result. In the DRAM the data are lost when the operating unit is switched off.

Peculiarities of MPI transfers

Requirements •

MPI download is possible with the following operating units: all graphics displays and OP3, C7-633, C7-634, C7-623, C7-624.

•

An MPI module is required on the configuration computer.

•

The configuration computer and operating unit are connected physically to the MPI network.

•

An MPI network can only be set up with a SIMATIC S7 PLC.

Setting the MPI address on the operating unit If you have downloaded the compiled project file for the first time, and serially at that, the operating unit has the configured MPI address. To carry out an MPI transfer, the standard screen System Settings must be configured in the project and the MPI transfer operating mode must be selected.

Multiple operating units in the MPI configuration If you want to integrate multiple operating units in the MPI configuration, you can only do it successively. 1. Connect the first operating unit physically. 2. Change to serial transfer mode, and download first the firmware and then the compiled project file. 3. Then connect the next operating unit physically, and so on.

Reason If you were to connect several operating units physically and then download the project, this would lead to an address conflict. All the operating units would have the same default MPI address, namely 1– which is not permissible in the MPI configuration.

Status/Force Tag

Purpose At runtime you can have direct access to the connected PLC (SIMATIC S5 and SIMATIC S7) from the operating unit to read and write values. This means you can monitor and change the PLC operands easily on the operating unit without having to connect a programming device or PC to the PLC as well. This is very advantageous particularly during the testing and commissioning phase of your project.

Requirements: In order to be able to access values on the PLC directly at runtime, the following requirements must be met: •

The connected PLC must be a SIMATIC S5 or SIMATIC S7

•

You must have integrated the two standard screens Status Tag and/or Force Tag in your project.

Standard screens The programming device function STATUS VAR is called in the standard screen Status Tag. This allows you to monitor PLC operands on the operating unit. Write access is not possible in this screen. The programming device function FORCE VAR is called in the standard screen Force Tag. This allows you to monitor and change PLC operands on the operating unit. You will find detailed descriptions about working with the two standard screens in the equipment manual for your operating unit.

Documenting and managing projects

Chapter ProTool subdivides printouts into chapters arranged by subject according to object types. For example, one chapter contains all the definitions on the subject of screens, another contains a list of all the tags and yet another a list of all the defined text or graphic lists. You can print several chapters at once or just print single chapters.

Reports ProTool offers you the facility of customizing printouts to suit your individual requirements. •

You can limit a printout to single chapters or single pages.

•

You can set the order in which the chapters appear.

•

You can decide which data you want to output within a chapter.

•

You can set margins, define your own headers and footers and embed your own graphic in the cover.

These definitions are stored in a report. Frequently required reports have been defined in ProTool in advance. But you can also create your own reports, as you wish. All reports are common to all projects. Every time you want to print, you choose the report with which you would like your output to conform.

7.1.2

Constraints with printing

Printer drivers Note the following constraints with certain printer drivers: •

It may not be possible to print the configuration with CANON drivers. Printing will be discontinued in this case.

•

With the Apple laser printer, the first line is not printed. This problem does not occur with drivers for the HP LaserJet III, PostScript or PostScript printers.

ASCII character set With some printers, it is not enough simply to set the ASCII character set in the configuration. Make sure the ASCII character set is set on the printer too.

Managing projects

7.3.1

Project management with integrated operation If you integrated ProTool into STEP 7 when you installed it, use "SIMATIC Manager" to manage your projects. You can then copy, move, back up and restore your projects in the same way as you have been used to from STEP 7. For further information refer to the documentation on SIMATIC Manager. Note ProTool’s Project Manager is not available to you in the event of integrated operation. ProTool data can no longer be viewed independently in this event, since the data is always linked to a STEP 7 project. It therefore has to be managed and backed up using this application.

7.3.2

Managing projects in stand-alone operation

Project Manager If you installed ProTool as a stand-alone version – in other words, if you are not operating it under STEP 7 – there is a user-friendly Project Manager incorporated into ProTool in place of the SIMATIC Manager. You can use it to manage your projects in a user-friendly way.

Usage With Project Manager, it is simple for you to: •

back up projects, even on more than one floppy disk

•

restore projects that you have backed up

•

open projects

•

delete projects

Call You start Project Manager by choosing File→ Project Manager from the menu. When you call Project Manager for the first time, the Find dialog box is displayed initially. Here you choose the drives and directories which have to be searched for ProTool files. Only those projects that are located within these directories are displayed by Project Manager.

Glossary A Acknowledge By acknowledging an alarm message, you confirm that you have taken notice of it. Thereafter the message is no longer displayed on the operating unit. You can acknowledge alarm messages on the operating unit or you can have then acknowledged by the PLC. If you assign alarm messages to acknowledgement groups, you can acknowledge several messages simultaneously.

Acknowledgement groups You can assign several alarm messages to an acknowledgement group when you are configuring. When the first message is acknowledged, all the other messages in the same acknowledgement group are acknowledged simultaneously. This means, for example, that you can acknowledge alarm messages referring to the cause of a malfunction and to all consequential malfunctions together (group acknowledgement).

Acquisition cycle The acquisition cycle determines the time interval in which the value of a tag is updated by the PLC. With a zero acquisition time, the tag is updated only when screens, messages and recipes containing that tag are displayed on the operating unit. The acquisition cycle is a multiple of the standard clock pulse.

Actions Actions are components of a unit. Their purpose within the process is to control a single actuator. In program terms, an action is •

a network in a LAD/CSF/STL program

•

a step in a S7-GRAPH program

ProTool User’s Guide Release 12/99

D-1

Glossary

Address multiplexing With address multiplexing, the address parameters of a tag are modified as a function of the value of a multiplex tag. In this way you can address a number of memory locations in the address area of the PLC (S7 CPU) with a single tag without having to define a tag for each address.

Alarm message Alarm messages provide information on the operating unit on malfunctions of the machine or system connected to the PLC. Message text may include current samples. Since alarm messages display extraordinary operating states, they have to be acknowledged.

Alarm messages (area pointer) You can configure an alarm message for each bit in this data area. The bits are assigned to message numbers in ascending order. As soon as the PLC sets a bit in this data area, the operating unit recognizes the assigned alarm message as having "arrived“. Conversely, the message is interpreted by the operating unit as having "departed" when the bit is reset on the PLC.

Area pointers An area pointer is a memory area defined by the user on the PLC. The area is used for exchanging data between the PLC and the operating unit. Synonym: user data area

B Background color You can assign a permanent color to the background of an output field, for example, or dynamically modify the color as a function of the value of a tag.

Backup You use the "Backup" function to archive projects created on your operating unit. Archived data can be read back in by means of the "Restore" function.

Bar graph A bar graph displays a value from the PLC as a rectangular area. You can use it to display fill levels or numbers of items produced, for example, on the operating unit.

D-2

Glossary

Baud rate The baud rate is a criterion for the speed with which data are transferred. The baud rate is specified in bits per second.

Button A button is a control element that is displayed on the screen. Buttons are touchsensitive on touch panels.

C Clipboard The Clipboard is a memory area on the configuration computer and is accessed by ProTool when you cut, copy and paste objects.

Compile Compile means you create an executable file from your project. You can download the file to the operating unit. During the compilation process, a consistency check is performed on the project.

CPU CPU is the abbreviation for central processing unit.

Cross-reference Cross-references provide information on which objects refer to each other in the project. If, for example, you wish to delete a variable, you will learn via the crossreference the points at which the variable is used in your project.

D Date/time (area pointer) The operating unit writes the data and time to this data area by means of a PLC job. These data can be evaluated by the PLC program.

Direct key module The optional direct key module for operator panels and touch panels has 8 or 16 digital outputs. It allows shortcuts on the operating unit without delays attributable to communications.

ProTool User’s Guide Release 12/99

Glossary

Direct key Direct keys allow shortcuts on the operating unit without delays attributable to communications. Direct key types •

PROFIBUS direct keys set bits in the I/O area of a SIMATIC S7 directly from the operating unit.

•

Direct keys for the direct key module control the outputs (ports) of the optional direct key module.

Download You use the "Download" function to transfer an executable project file to the operating unit. Before you can do so, connect the operating unit to the configuration computer by means of a standard cable.

Dynamic attributes Dynamic attributes control, for example, the colors of an input or output field as a function of the value of a tag and enable or disable flashing for displaying the contents of that field.

E Editing language The editing language is the language in which you create text for your project.

Event message Event messages provide information on the operating unit on operating states of the machine or system connected to the PLC. Message text may include current samples.

Event messages (area pointer) You can configure an event message for each bit in this data area. The bits are assigned to message numbers in ascending order. As soon as the PLC sets a bit in this data area, the operating unit recognizes the assigned event message as having "arrived“. Conversely, the message is interpreted by the operating unit as having "departed" when the bit is reset on the PLC.

Event Functions are triggered upon the occurrence of defined events - for example, upon pressing or releasing a key. Events can be configured as a function of an object.

D-4

ProTool User’s Guide Release 12/99

Glossary

Export You can export configured messages as a text file to translate them into a different language with an external editor, for example. Using the ProTool’s import function, you can reimport the text file into your project.

F Fixed window The fixed window is a window that is always located at the top border of the operating unit screen. You can adjust its height. Since the contents of the fixed window do not depend on the current screen, you can output important process tags or the date and time to it, for example.

Flash memory A flash memory is a programmable memory that can be erased and then rewritten.

Foreground color The foreground color of an output field, for example, determines the color of the value or text output to it. You can either permanently configure this color or dynamically modify it as a function of the value of a tag.

Function key A function key is a key on the operating unit for configuring a function assignment. A function key with a global function assignment always triggers the same function irrespective of the screen that is currently open. A function key with a local function assignment (soft key) can trigger a different function on every screen.

Function keyboard (area pointer) The operating unit transfers function key operations via this data area. You can evaluate this information in the PLC program in order to draw attention to an incorrect operation by means of a message, for example.

ProTool User’s Guide Release 12/99

D-5

Glossary

G Global function Global functions are not assigned to any particular objects but are linked to specific events. If, for example, you configure the Set Bit function as a global function with the condition Enter Value, a bit is set every time a value is entered. Irrespective of the field selected.

Global tag Global tags (process variables) establish the connection to the PLC. You have a set address on the PLC. The operating unit reads and writes to and from that address.

Graphic list A graphic list assigns a graphic to every value of a tag. This means, for example, that you can display the assigned graphic on the operating unit in an output field instead of a value.

Group acknowledgement You can assign any alarm message to an acknowledgement group when you are configuring. When the alarm message is acknowledged, all the other messages in the same acknowledgement group are acknowledged simultaneously too.

Guide line You can define a horizontal guide line in a trend graphic for each of the two Y axes in order to gain a quick overview of the deviation of the actual values from their setpoint.

I Icon An icon is a fixed-size pixel graphic. You can assign icons to soft keys, for example, in order to illustrate their function.

Identification Freely definable identifications are available for identification of recipes on the PLC. The identifications are transferred together with the data records from the operating unit to the PLC and can be evaluated by the PLC. The identifications are stored in the data mailbox on the PLC.

Glossary

Import You reimport text files back into your project that you exported with ProTool’s export function in order, for example to translate then into another language with an external editor.

Index tag An index tag is a tag that refers to different tags, trends, bar graphs or input/output fields as a function of their value. Index tags are used in multiplexing.

Input field An input field is where you enter values on the operating unit that are transferred to the PLC.

Interface area The interface area is the interface between PLC program and operating unit. It contains data and pointers to areas required for exchanging data between the PLC and the operating unit.

Invisible button An invisible button is a control element that is visible while you are programming but not at runtime. If you place invisible buttons over a component on your process screen, you can operate that component by clicking it with your mouse (Windows system) or by touching it (touch panels).

J Job mailbox The PLC uses this data area to pass PLC jobs to the operating unit to initiate specific functions for example, display a screen.

L LED assignment This area pointer can be used by the PLC to drive the light-emitting diodes on the function keys of the operating unit.

Limit value You can set for tags an upper and a lower limit value that is determined by a constant or by a tag. The effects of the specified limit values being exceeded are as follows:

ProTool User’s Guide Release 12/99

Glossary

•

Input field: input is rejected on the operating unit.

•

Output field: Values are output in the color configured.

•

Trends: Trend values are displayed in the color configured.

•

Bar graph: The bar graph is displayed in the color configured.

Local tag Local tags are not connected to the PLC. They are available only on the operating unit.

Log off time With the configurable logoff time you set the time after which the password level is reset to zero if the operating unit is not operated within that time.

M Message arrival The arrival of a message denotes the time at which the message is initiated by the PLC or operating unit.

Message buffer A message buffer is a memory area on the operating unit in which message events are stored in chronological order when they arrive. Event messages and alarm messages are stored in separate message buffers.

Message departure The departure of a message indicates the time at which a message is withdrawn by the PLC.

Message event Message events are the: •

Message arrival

•

Acknowledgement of a message

•

Message departure

Message events are stored in chronological order in the message archive on the operating unit.

Glossary

Message indicator The message indicator is a graphic symbol that is displayed on the operating unit while at least one alarm message is queued.

Message logging With message logging, messages are output to the printer in addition to being displayed on the operating unit.

Movements Movements relate to sequences in the process that can be monitored with the aid of error definitions in the process diagnosis. There can be several error definitions for each movement. A movement can be contained within a unit and represents an actual movement on the part of a physical object within the process (e.g. a die moves up and down). Movements are defined in S7-PDIAG by the "movement" UDT being used in a block.

Multiplex tag A multiplex tag is a tag that is selected at runtime as a function of the value of an index tag.

Multiplexing In multiplexing, trends, bar graphs or input/output fields are assigned several tags. Assignment depends on the value of an index tag. Using the index tag, you can control all the tags of a screen, for example. This spares you the trouble of configuring several screens for similar applications.

O Object type The object type specifies whether values or symbols can be entered in or output to an object on the operating unit.

Object An object is an integral part of a screen or a message. Depending on the object type, objects are used to display or enter text and values on the operating unit.

Online Help ProTool’s online Help provides you with context-dependent information on your screen while you are configuring.

Glossary

OP Acknowledgement This area pointer is used by the operating unit to inform the PLC which alarm messages have been acknowledged on the operating unit.

OP OP is the abbreviation for operator panel.

Operator panel An operator panel (OP) is a configurable operating unit for operating and monitoring machines and systems.

Output field An output field displays current values from the PLC on the operating unit.

Overflow warning The overflow warning is a message that is output to the operating unit as soon as the configured size of the remaining buffer is reached or exceeded.

P Password level You can specifically restrict the privileges of operating the operating unit to certain users or groups of users. To do this, you assign hierarchically ascending password levels to individual functions, function keys and input fields. The password level is linked to the password. It entitles you execute functions at that or a lower password level on the operating unit.

Password A password is a string of characters that you have to enter on the operating unit before you are able to execute a protected function. A defined password level is assigned to every password.

Pattern trend With a pattern trend, all trend values are read simultaneously from the PLC and displayed as a trend on the operating unit by setting a trigger bit. Pattern trends are suitable for displaying rapid changes if the trend variation, seen in its entirety, (profile) is more interesting than individual values.

D-10

ProTool User’s Guide Release 12/99

Glossary

PLC Acknowledgement This area pointer is used by the PLC to inform the operating unit which alarm messages have been acknowledged by the PLC.

PLC job You can trigger functions on the operating unit by means of PLC jobs by the PLC program - for example, Display Screen.

PLC PLC is the abbreviation for programmable logic control.

Print Screen Print Screen prints a copy of the contents of the operating unit screen. Open windows are not printed.

R Realtime trend With a realtime trend only one trend value at a time is read from the PLC for each clock pulse or trigger and added to the trend displayed on the operating unit. If the configured number of samples has been reached, the oldest value is overwritten by every new one. Realtime trends are suitable for displaying continuous patterns.

Reference language With multi-lingual projects, the reference language (reference text) serves as a basis for translations into other languages.

Reference text With multi-lingual projects, the reference text serves as a basis for translations into other languages. Reference texts cannot be edited.

Remaining buffer The remaining buffer is the configurable size of the message buffer at which an overflow warning is issued when it is exceeded.

Restore With the "Restore“ function you read data back in which you had previously archived using the "Backup“ function.

ProTool User’s Guide Release 12/99

Glossary

S Screen number (area pointer) In this data area the operating unit stores information on the current screen. You can evaluate this information in the PLC program to call another screen, for example.

Screen A screen is a group of logically related process data that can be displayed collectively on the operating unit and modified individually. Screens consist of static and dynamic components. Static components are text and graphics, dynamic components are, for example, input and output fields.

Soft key A soft key is a function key with a locally assigned function on the operating unit. Depending on the current screen, a soft key can trigger different functions.

Standard clock pulse The standard clock pulse of the operating unit is the basic factor for the update rate, which you can set by means of the acquisition cycle of the tag. You globally modify the acquisition cycle for all the tags of a project by modifying the standard clock pulse.

Start value The initial value is the value with which a tag preset following downloading of a new project or following deletion of the buffer. You can configure the start value.

Supervisor The supervisor is the user who is entitled to execute functions at the highest password level. He therefore has access to all the functions of the operating unit.

Switch buffer A switch buffer is a second buffer which you can create for a pattern trend. While the operating unit is reading the trend values from buffer 1, the PLC is already writing the new values to buffer 2. When the operating unit is reading buffer 2, the PLC is writing to buffer 1. The switch buffer prevents the PLC from overwriting values while the operating unit is reading the trend.

System keyboard (area pointer) The operating unit transfers system key operations via this data area. You can evaluate this information in the PLC program in order to draw attention to an incorrect operation by means of a message, for example.

D-12

ProTool User’s Guide Release 12/99

T Tag A tag is a defined memory address to and from which values are written and read, respectively. This can be done by the PLC or by means of the operating unit. A distinction is made between global tags (process tags) and local tags, depending on whether a tag is linked to the PLC or not.

Text list A text list assigns text to every value of a tag. This means, for example, that you can display the assigned text on the operating unit in an output field instead of a value.

Text or graphic list Text or graphic list is the collective expression for text list and graphic list. A text or graphic list assigns text or a graphic to every value of a tag.

Transitions A transition describes a condition for progressing from one step to the next within a sequence of steps. Transitions occur only with S7-GRAPH.

Trend request This area pointer can be used by the PLC to evaluate which trend is currently being displayed on the operating unit.

ProTool User’s Guide Release 12/99

D-13

Glossary

Trend transfer area 1 This data area is used to trigger trends. As soon as the PLC program sets the bit assigned to the trend and the trend communication bit in the trend transfer area, the operating unit detects the trigger and, depending on the setting in your project, reads out either a value or the entire buffer.

Trend transfer area 2 This data area is required when you configure trends with a switch buffer. The data area is structured in exactly the same manner as the trend transfer 1 data area.

Trend A trend continuously displays a value from the PLC as a line or a bar graph on the operating unit. Depending on the type of trend value acquisition, a distinction is made between realtime trends and pattern trends.

U Units A unit is a block in S7-PDIAG and a sequence of steps in S7-GRAPH. Units are objects of the process diagnosis that are monitored with the aid of error definitions. There can be several error definitions for each unit. Units can be physical objects in the process (e.g. a press or die) which in turn can incorporate movements (e.g. forward/backwards, up/down). Units are logical hierarchical criteria and structure the view of the process They may store data that is shared by all hierarchically subordinate objects. Hierarchically subordinate objects can in turn be other units or movements, for example. Each unit can incorporate one or more actions.

Update time The update time is the sum of the polling time, download time and processing time.
