Introduction

T

He Elipse Scada is a software for the creation of process supervision and control applications for several areas. It can be completely configured by the user which allows the monitoring process variables in real time through graphs and objects that are related to field physical variables. Furthermore, the user will be able to operate and send or receive information to the data acquisition equipment. It is also possible to make calculations using the programming language, to create historical databases, reports, recipes, and even to supervises and control remotely a process. The software is avilable in four modules: View, MMI (Man Machine Interface), Professional and Power. All the forementioned modules have Configurator, Runtime, and Master versions. The Configurator is dedicated to the process supervision applications development. In order to conductor tests, the Configurator can run applications up to ten minutes. The Runtime is used to run process supervision applications after they have been developed making use of the Configurator. The Master embodies in the same tool one Configurator module and one Runtime module, which allow the set up and running in one sole product. In the absence of a protection device (hardkey), the software can be run in demo mode. The Demo is used to asses the software and it has all the existing resources as in the Configurator. However, it works with a maximum f 20 Tags, allowing the communication with the data acquisition equipment up to 10 minutes, with the condition that there is the respective communication driver. It does not use a hardkey and can be freely reproduced.

Installation

2.1. System Set up See the following for the minimum requirement for the machine (PC):  Pentium 100 MHz or superior  Memory 16 MB (32 MB recommended)  SVGA Monitor(800 x 600, 256 colors or superior)  Microsoft Windows 95 / 98 / Millenium/ XP or NT  1 parallel port.

2.2. Installing 1 – Insert the Hardkey in your computer parallel port, if there is already a printer in this port place the hardkey first and then connect the printer in the same port. 2 – Introduce the floppy disk or CD-ROM in the respective drive, and through the Start button choose the Run option. 3 – In the unit that you are using, choose the INSTALL.EXE command, and follow the instructions that are displayed on the screen.

2.3. Updating Periodically, Elipse launches new software Releases that contain new tolls and/or updates for the already existing ones. Such updates can be obtained through common media (Floppy disk or CD-ROM) or through our site: www.elipse.com.br. In the case

 Elipse Software

of updating, only the files that change with each release are available in Internet which turns the updated version smaller than the installed one.

2.4. About the Hardkey Some older keys have some compatibility difficulties with HP (Hewlett-Packard)® printers, when running in the “Bi-directional Communication” mode. For the correction of such problem there are two procedures: a) Run through the Running command of your Windows or one of the MS_DOS sections the hinstall.exe program that is copied during the installation process to the same directory in which the software was installed) that is responsible for the hardkey installation according to the syntax below, selecting the Bi-directional option. HINSTALL.EXE [options] Options: /i – Installs the hardkey driver (HASP) /iu – update /r – remove /portmode= tipo:

Normal – normal port mode ECP – Enchanced Control Port modo BiDi –Bidirecional mode Auto –automatic mode

b)To run a printer set up utility in the c:\Windows directory or your machine equivalent, disabling the Bi-directional communication option..

2.5. Hardkey update In the case you need an eventual version change (e.g. MMI to PRO) or even the increase in the number of tags in one application, the safety key will be able to be remotely programmed. For that purpose, besides the usual commercial procedures, the user will be able to follow the next steps, so that the update is performed as fast as possible:

Case Study n our training example, we will create an application as shown below.

The mentioned System shows a candy plant sunoptic. For the production, it is necessary four basic products: water, syrup, glucose and sugar, whose qualities are controller for each new type of candy to be produced through the use of recipes that are programmed by the operator. After the individual weighing of each products, they are homogenized in the mixer which in turn transfers the moisture to a storage tank. This transference between tanks can be automatic or controlled by a valve drive. From the storage tank, the moisture is transferred to the cookers through pumping that it also controlled by the application. The system operator can visualize each tank temperature in the same screen, control the engines frequency and open or close valves that drive the moisture to the cookers. The system will also show alarm status, in the case the parameters exceed the established limits. (e.g. excessive temperature increase), besides creating temperature trend graphics, generate operating database and its respective reports. Throughout the register screen, it is possible to create new products and edit the already existing ones. There is also a Query procedure for batch processes that allow historical data Query, visualization and printing.

In order to allow a simple and organized view of the entire application, the Elipse Organizer command in the File menu or pressing the

button in the toolbar.

The organizer structure can be compared to a directory tree of the Windows Explorer. In this way, the application structure starts in the upper left corner with the application’s root. All application objects go down from the root , grouped according to their type: tags, Screen, Alarms, recipes, Historical, reports, Drivers, databases, User’s List and Remote Applications. Selecting any of the tree legs of the application will make it expand showing its content – so you will be able to navigate through the application having all the set up options available for any object. Starting from the Organizer, you can create all your application only but navigating through the application tree. Selecting any of this legs, the selected object properties will be editing. For instance, if you select Tags in the Organizer tree, new Tags can be created, and its properties can be edited selecting the page you wish from the tabs in the top of the window. The Organizer Toolbar buttons allow you to quickly perform certain tasks without using the menus. There are 13 buttons as you may see in the following table:

Tags Process supervision with the Elipse Scada takes place through process variable readings in the field. The values of these variables will be stored in tags.

At least one Tag or Attribute must be associate for each animation object inserted in the screen. Tags are all the variables (numerical or alphanumeric) involved in one application. It can be of several types, according to purpose of use. Attributes are data furnished by the Elipse Scada about system parameters and Application components. For instance, we can consider a tag as furnace temperature, and one of its attributes is the alarm level from which the siren will be activated. Tag values or associate Attribute value can be displayed by the animation objects in the Screen, used in calculations through the scripts, modified through the operator’s actions, and so on. In creating Tags, the user will be able to organizer them in Groups as he may wish, so to make it easier the search and identification during the set up process. To create groups, just select the Tags item in the Organizer and click in New Group. You can create groups within other groups, and if you wish to change their position, (e.g. to include it in other group) just drag it to another position and the whole content will also be moved. See the following list for the existing type of Tags:

5.1. Tags Type TYPES

DESCRIPTION

PLC

It is used to exchange information with the data acquisition equipment (writing and reading) through communication drivers. The requested parameters are obtained through the help file that come along with each communication driver.

DDE

(Dynamic Data Exchange) – Tag for data exchange with other applications. It represents one manner of exchanging data between applications (e.g. Excel, Acces, Word, etc), or further between communication drivers “DDE Server” supplied by a manufacturer.

Demo

Tag for values simulation. It allows to create defined curves or random values from the selection in the buttons that are displayed in the window.

Expression

Tag that allows the input of a numerical or alphanumerical expression (it allows a sum between strings).

Block

Similar to the PLCType Tag, however it allows the reading of several simultaneous data. In some cases the use of Block type tags enhances the communication.

RAM

Tag of internal use to store values in the memory. Tags of RAM type are volatile that means, they store values while the application is open.

Matrix

These are RAM tags set in order to allow vector and matrix access.

Counter

It allows the creation of counters and timers.

5.1.1.Rules for Tags names In order to specify tags names some details must be followed:  The variable name cannot contain reserved characters such as: logic and arithmetic operators, ? , . , - , + , * , etc.  The variable name cannot contain space: This is also valid to the other properties that are not tags, if you wish to use them in scripts (programming language), since the compiler will take them as distinct variables.  The tag name cannot be strictly numeric. The following examples inform the tags creation procedures. If you have an equipment and wish to perform communications, choose the creation of variables type PLC or

 Elipse Software

5-2

Elipse Scada

T A G S

Block; otherwise, choose the Demo type, that will allow the simulation of values in the absence of real data.

5.2. Creating Tags To create new Tags, just select Tags item (for creating a root) or a specify group (for creating a group) and click in New Tag, where the following help box will be displayed:

In whick name (following the mentioned rules), quantity (in case you create more than automatic numbering at the end of the names will be created) and type shall be informed.

5.2.1. PLC Tags PLC type are generally used when you wish that a tag access communication driver reads/writes a value or a set of values to a single variable. Therefore, it can represent any type of variable independently as an input or an output, digital or analogical, depending on the set up and address required by the communication driver.

 Elipse Software

5-3

Elipse Scada

T A G S

Each tag PLC or Block must be associated to a communication driver, which will be responsible for the communication with the specific equipment. You must set up the communication driver at least once when a new application takes place.

5.2.1.1.Communication driver The Elipse Scada drivers are separate files with DDL extension that can be placed in and directory to be defined by user. To set up a new driver, just click in the Drivers item from the Organizer – then in the New button loading the correspondent DDL file. By choosing the Set up option it is possible to specify the general data about communication, as serial port, communication rate, and so on, according to the supplied documentation to each communication driver. To assist the set up task, you must access the Driver Help option where the driver set up parameters is displayed. FIELD

DESCRIPTION

Driver Location

It shows the path where the DDL file is.

Parameters

It allows the communication general parameters set up, such as serial port, communication rate, according to the supplied documentation and help.

Abort on Error

This option displays a dialog box requesting the annulment of the communication with the driver, in case of communication error. This option must be used only in the set up, since its running can be dangerous, in the sense that if the operator answer “Yes”, all the communication will be suspended.

Hide mouse during communication

The “Hide mouse during communication” option can be used to verify interruption conflict in the serial port (generally not used) and the “retry failure communication” can be specify a retry number in case for error (generally disabled).

Retry failed communications/ Number of Retries

Extra try number in case of communication error. Use this property with caution, because if the equipment presents continuous communication errors a general review of all communication will be necessary- otherwise it will cause delay on the general answer of the software.

Consult at the end of this manual the exhibits related to some help examples of communication driver. Through the Advanced button you will have access to more detailed set u about the driver operation.

DESCRIPTION

Maintain 16-bit driver behavior

When enabled, it is the normal operation mode of the 16 bits versions. If disabled, it operates the hybrid multitask mode that is 32 bits version pattern. This operation mode of the 32 bits drivers places all the communication task in a separate process, in asynchronous way compared to the Elipse Scada normal operation, speeding up the application process. This method is only suspended when there are the user’s clear restrictions to obtain a variable value, such as a script (program), where the following step dependes on the tag value update, when the process of information exchange between the communication driver and the main program becomes synchronous.

Use background writing

It also allows the writing perform in parallel process, however it allows placing the write requirement to the driver with the same priority of others requirements (low priority) or in the top of the requirement list (high priority).

Start driver at application startup

This option allows that on starting an application the communication driver be ready to exchange information, or in another works, it automatically runs its function via some script, in order to allow the communication.

Keep driver in memory

When in set up, this option allows that the elipse Scada does not unload the memory driver every time it returns to the development enviromment.

Through the extra Button, available in some drivers, you will have access to special parameters of the set up, such as modems use and Debug or trace file creation of communication Consult the driver documentation to learn more about these parameters.

5.2.7.Tag Bit Tag Bit can only be created starting form another tag, and it allows to individually access each bit of it. Those Tags that allow the separation in bits are: PLC, Demo, Expression, Block Elements, Ram or Remote. This resource is very useful when a read value of an equipment, such as a byte or word, actually represents 8 or 16 (or more) independent digital status (on or off). The bit value is obtained through the masking of the bit position with the tag to which it belongs. On the other hand, the writing is made in two ways: masking and writing the whole or written word of the individual bit, if the equipment supports such command that is implemented in a transparent way to the user in the communication driver. You can create a Tag Bit from the General page of any of the above mentioned tags. Clicking the Access bits… button the following windows will be displayed, where you will be able to select the bits that you wish to be mapped. The bit selection is made using the mouse and the SHIFT or CTRL keys, in the same way the items are selected in a windows list box.

The tag bit can be whether a single bit or a bit set, once they are continuous. That means that you can map one single Tag Bit, for instance, the 0,1, and 2 bits, but not the 10,11 and 24 bits. A check box existing in this window allows to specify if a Tag to each selected bit must be created or if the continuos bits that are selected must be gathered in one single Tag.

Whenever it is possible the use of tags block allows the inserting of the physical means, for in a generic serial communication process, great part of the characters transmitted belong to control and checking. By using blocks we make such characters to be sent in a smaller number of times due to the encapsulating of the great number of variables in the same transmission. COMMUNICATION TAGS SCAN TIME SETTING

Try to program the variable scan time with the closest real values. If a very low scan time is specified to all the variables, probably the following will take place, due to pysical means limitation: not all the variables will be collected in the specified rate, which will create a performance decrease in the communication, not allowing that certain variables that really need a faster search be in charge of the communication. TIME INFORMATION IN THE TAGS

Some equipment allow sending time information together with the variable values. The communication driver for such equipment can also return this clock information, in each consulted tags. This information can be obtained through the TimeStamp property, in all tags, with an accurcy of 1 ms. When the equipment does not support this kind of information, or when the driver is not ready for such procedure, the program itself will perform the information task at the moment of collection, filling up with the PLC watch value. Remark: In the case of Block tag type, the same TimeStamp is informed to all the block elements, once they have already been consulted at the same time. If they are distinct events they must be read as tag of PLC type.

5.2.11.Alarms Page Each Tag that is defined has an Alarms page as the one shown below in which 4 range values and priorities to Alarms can be set. Alarms are used to signalize any event that may happen with a variable, also allowing take the appropriate actions through the Scripts (programs).

Screen Creation Screen can be defined as a process monitoring window, in which the objects that will do the operator interface with the system will be inserted. Each application can have an unlimited number of screen.

You can create a new Screen pressing the new Screen button in the Toolbar or using the New command in the Screen menu. In this new Screen, you can define the Screen Objects, walpaper and other specific features. For a better graffic quality of the system that is being monitored you can insert a wallpaper to the Screen. The format used today by the Elipse Scada is a grafical file with BMP, GIF or JPG extension that can be created in several specific draw Windows applications, as the paintbrush (Windows 95/98/2000/etc), CorelDraw, Paint ShopPro, Autocad and others. You can create your own drawing (bitmaps) in any size and color you wish. The Elipse Scada will automatically import them without using a conversion process. To visualize or edit the current Screen properties, double click in an empty window is displayed, containing a list of all the Screen in you application. You can create a new Screen using the New button in the right side of the page or remove and then the bdelete button.

Screen Objects N application Screen can contain background and objects bitmaps. The objects that are inserted over the bitmap constitute a secondary ground in the screen, in a way that it can be detected, copied, moved, resized, and bracketed, without damaging the background.

The screen objects, therefore, are graphical elements that are related to the tags so that it is possible to make a friendly interface with the variables. The previously available objects are as it follows: Slider: It allows to visualize or send values toa tag through a potentiometer (sliding button). Trend: It is used to visualize a trend graphic with up to 16 tags (that can be exchanged in the running), running the real time collection or in background, besides perform variable graphics by time, or the variables relating to others (XY). Button: For activating or running the specific tasks by the user through the mouse or key, being able to assume several formats and functionality.. Gauge: Displayer of analog values with the pointers. Text: This object allows attributing messages in Tags range values, called Areas, defining colors and messages fo each Area. Bars: It is used to visualize the data in volume appearance. It can be displayed up to 16 tags in each bar object. Display: Numerical/Alphanumerical displayer in real time. Animation: To create animation using bitmaps defined by the users.

Setpoint: It is an editing box, for keyboarding and sending values to a variable. Alarms: It allows the visualization of the activated alarms () or the alarms logged in the alarm file (Historical). Browser: It allows the visualization of databases files in the screen. Bitmap: it allows the visualization of databases files in the screen. Video: The Video object allows you to show a video source, displaying a realtime video or a playback. Avi: The AVI object allows you to playback an AVI file. You can edit AVI properties double-clicking the object. Preview: The Preview object allows you show a video source.

7.1. Screen Object Edition The Screen Objects can be created from the toolbar Objects or through the Object Menu. Once selected the object that you wish to create, keep the left mouse button pressed in the screen area while moving the moouse (a spotted rectangle shows the size abd shape of the object). When you drop the button the object will be placed in the specified area. Insert any two objects in the screen (e.g: two buttons), so that you can verify and use the following tips: MAKING COPIES OF SCREEN OBJECTS

We can copy screen objects by pressing the CTRL key while we drag the object we wish to copy. This action will create a new screen object that will have the same properties as the copied object. You can even use the basic Copy (CTRL+C) and Paste (CTRL+ V) commands of the Windows.

OBJECTS OVERLAP

If you have two screen objects, and part of one has to be over the other, you need to adjust the disposal through the Bring to Front

and Send to back

buttons.

NAVIGATING COMMAND BETWEEN OBJECTS WITH KEYBOARD/MOUSE INPUT

When inserting a series of screen objects, it is possible (in running) key to shift from one object to another by using the Tab, as two Set-points for instance. Initially, the shifting through the Tabs follows the object creation command in the screen. However, it is possible to easily change this command with a little trick:: 1) Select the objects in the desired Tab order. 2) Press the Bring to Front or Send to Back buttons. The objects that were brought to the front will be arranged firstly in the navigation command, and the other that were sent to the back will be placed lastly. The Screen Objects Edition, such as aligment, size, position and bracketing is done through the toolbar Settle or through the menu. The last selected object will have the focua in red to be used as a reference. To deselect an object use the key combination: SHIFT+CTRL+left button. SELECTING ALL THE SCREEN OBJECTS

To select all the objects contained on a screen, just press the Ctrl+A keys. SELECTING SOME SCREEN OBJECTS

To select the objects contained in an area, use the tool selection can select the objects within a mouse delimited area.

Down arrow: It descends the object 1 point down; Right arrow: It moves the object 1 point to the right; Left arrow: It moves the object 1 point to the left; Combining the directional keys with CTRL, you can make the object transference 10 times faster. Combining the directional keys with SHIFT, you can resize the object. Some examples: CTRL+Up arrow: It rises the object 10 points; SHIFT + Left arrow: It decreases in 1 point the object width; CTRL + SHIFT + Right arrow: It increases in 10 points the object width;

7.2. Screen Object Properties Once a screen object is inserted, its properties can be acessed in many different ways: a) Through a double click on the object; b) Selecting the object and using the Objects – Properties menus; c) Selecting the object and clicking in the button in the toolbar. d) Via Organizer, in which you can access the screen, and by clicking in the + symbol, the objects belonging to that screen will be displayed. All the objects have 3 property pages in common, as follows:

Scripts

T

he scripts are programming language module, in which code lines can be created that allow a higher flexibility to associate actions to specific events. Each item of the Elipse Scada application has an event list previously associated. Thus, the user will be able to create programs that will be executed in the incident of a specific event..

8.1. General Considerations In any programming language it is necessary to create methods in order to specify and organize the desired instruction running. The Elipse Scada script structure itself is already organized in this manner, once they are oriented to events. The events are incidents related to an object that can be handled in order to execute an action. The events can be physical, as for instance, a keyboard action. In this case, the relavant information would be pressing the key (among others), or if the event comes from the mouse, the relevant information would be the cursor position and the button status. The events can be internal, with a variable value change, but can have a physical association, such as a chamber temperature change from 10 to 11 degrees. The event conditions that may occur with the objects are already handled by the Elipse Scada, and areavailable to the user to connect the program (scripts) to them. Here there is an event list already available to the script running, listing the generating type of action or prevailing in the event generation, with its name and a list of objects that support the events.

 The

language used in the script modules are defined by the Elipse Basic, and is very similar to the C language, but with visual resource such as the Visual basic. Different from the programs in the mentioned languages, some considerations can be made :

 It

is not necessary vaiable or function declaration in the beginning of the script. The variables that can be tags/ objects/ attributes must be previously created, imported from other application, or yet it can be used as patterms that already part of any application, at the moment they are created.

 The

data type that is attributed to a tag is free, and the supported value can range from a whole number of the 8 bits to a real type of the 64 bits, or yet, a string (text). When repassed to the communication driver or received from it, the conversions to the supported types to different equipment are made . In the properties case, an icon supported type data, as listed below: Numeric attribute (whole number) Numeric attribute (real number) String attribute (text) Boleano attribute (0 or 1).

The variable (tags/attributes( and constants are the basic objects that can be manipulated in the script. The operators specify what will be carried on with therm; on the other hand, the expressions match variables and constants to procedure new values. To make the scripts edition or tags expression easier, the command buttons in the Organizer toolbar, the App Browser and the X-Reference (Crossed Reference) can be used.

8.2. App Browser & X-Reference The App Browser allows you to easily navigate in the application. When you select an object in the tree in the window left side, its attributes and functions are displayed in the right side. You can use the App Browser as reference during the script edition. A very useful feature is to select object/attribute/function that you seek to copy right to the Script in (Copy to Script ->). The App Browser window is displayed as follows:

Note

When attributing a value directly to a PLC tag or Block Element that has the property automatic writing enabled, the command is sent directly to the communication driver that in its turn repast it to the associated equipment. Such action does not take place only when the avlue attributed is equal to the content that was is the tag. In case you want to force a writing whatever, the tag Write() function must be executed in any script.

8.4. Flow Control In order to control the order in which the information is processed, a flux control information is used. The Elipse basic language uses the following set of controls

8.4.1.If…ElseIf…Else…EndIf Command It is used to make decisions. Formally, its syntax is: If condition1 [instruction block 1] ElseIf condição2 [instruction block 2] ] ... Else [instruction block n] ] EndIf

The screen object functions can be accessed first through the screen selection that contain it, soon after the object. The plotting function can be found in the trend graphic objects, historical Analysis and graphic report. And the Query functions are used by the objects, histprical Analysis and graphic report.

8.6. Tips and Optimization SCRIPTS EDITION

To build a scripts, besides using the App Browser, you can freely edit the lines in any text editor of the Windows. Thus, the pattern operations such as Copy (CTRL+C), Paste (CTRL+V), Cut (CTRL+X) and Undo (CTRL+Z) can be used. Besides that, the Find and Replace tools, present in any script, can be used.

SCRIPTS COMPILATION

Always before running an application we must check if it does not have any errors. This is a very important task, once the scripts that contain syntax errors (that means, poperty names or wrong objects or not existing ones) will not run. Using the Compile Scripts, Build Scripts, Rebuild All Scripts buttons that are in the inferior part of the Organizer, we can make this verification in a faster manner. Use the Compile Scripts button to check script errors that are being edited in the moment. This button will not verifies only the scripts that were not yet compiled. The Rebuild All Scripts button verifies all the application scripts without considering if the they were changed or not. The time difference that this operating takes to be executed regarding the Build Scripts is slightly higher to the large application, but is very useful to avoid running errors. When using these two last options, a window click in the red line, the scripts with errors are automatically edited. SCRIPTS ERROR

If during the script running an error of the following type takes place: a) The script contain compilation errors and you run it whatever; b) You are attributing parameters of incompatible types (e.g. forcing a string to a digital attribute). c) There was a division by zero – the Script will be aborted. To avoid this kind of problem, always compile your files, and verify the change of this problems happing again. SEQUENCING SCRIPTS

As the scripts are priented to events, there is a chance of running the scripts inside others, due to the used operation sequencing. As the following example: Script OnAlarmHigh of the variable tag001 tag002 = 1 tag003=0

Script OnValueChanged of the variable tag002

 Elipse Software

8-10

Elipse Windows

S C R I P T S

Screen1.Activate() In this case, at the moment that the tag001 is in the alarm condition (that was previouly defined by the user) the first script attributes a value 1 to the tag002. When performing such task, the tag001 script is interrupted, so it can verify in the value attribution cause to the tag002. When this occurs, in general it id verified if the tag002 has any script associatd (so that will be necessary to run them too, since occurred an event to the tag002) or if there is any screen object connected to it. Thus, the script OnValueChanged of the tag002 is run, and only then is returned to the origin point, from where it stopped in the script of the tga001. COMMENTS

It can be insert comments in the scripts with two simples bars placed in the left side from the point where you want to meke a comment. Examples: Tag001 = 25 // this is a comment INTERN VARIABLE

You can create internally variable in the script. After the running, it will be destroyed. The used command is DIM. Example: DIM FLAG FOR FLAG=0 To 10 Tag001=FLAG NEXT SCRIPT RETURN

If you wantwant to leave a script before its end, use the RETURN command. Example: IF Tag001 > 10 RETURN

S C R I P T S

ENDIF Tag002=10 In the example above, if the Tag001 is higher then 10 the script is abandoned. On the contrary, its running normally continues. RESTRICTION THE USE OF INFINITE TIES

If the control ties such as While and Repeat are used to create inifite ties, they can interrupt the running of other software tasks. As the following example: WHILE Tag001 Tag002+=Tag003 WEND In the script above, the available tag001 is evaluated; if real, that is, different from zero, it start the running of the first instruction that increases the tag002 of the value of the tag003. After that, the tag001 is evaluated again, and the running continues with the possibility of receiving the answer of the communication driver with the tag001 value. In order to eliminate the problem, one of the solution is to force the reading of the tag001 in the end of each loop, as in the example: WHILE Tag001 Tag002+=Tag003 Tag001.Read() WEND LIMITATION IN THE RUNNING SCRIPTS BY TIME

The scripts WhileRunning generally spend more processing time them the other scripts. Using the ScriptWindow() function that it is also a tool you can verify while running how long each script takes to be executed. Thus, you must guarantee that a Script WhileRunningFinnish. Its execution before calling it again, in order to avaiod a running request accumulation. TOO LONG SCRIPTS

It aviods the creation of too long scripts. When you separate them in small parts the time spent consireably decreases; and as said bove, use the debugging function to optimize the scripts. A deparation between scripts sughestion could be as follows: Create a RAM type, wich can be called, for instabce, functionA. At some point, in the script to be separated, make an attribution to the functionA. Script WhileRunning – Aplication ……. ……. FunctionA=1 In FunctionA create a um script OnValueChanged, and copy the part of the first script that will be executed on it. As the last instruction, return the tag FunctionA to its initial value. Script OnValueChanged - FunctionA ……. ……. FunctionA=0 BUTTONS SCRIPTS

In one of the level or temperature variable, create a script OnAlarmHigh, running the screen exchange function to alarm screen, through the execution of the Activate() function of it. The result will be the same of the previous script, but it is being called by two different events. OBJECT COLOR EXCHANGE IN ALARM INCIDENT

In the tag temp01 make through a script OnAlarmHigh change the display color in the screen, through the property backgroundColor change, and with the help of the RGB(r,g,b) function present in the Global Manager.

On the other hand, the SetMouseCapture function causes all the Windows messages, generated by the mouse, to be sent to the object in point. Thus you can test if the pointer is inside or outside the area, resulting in the changig of draws. Run the application, and when you pass the mouse over the bitmap, you will see that the drw chages from black and white to colored. CREATING MANUAL/AUTOMATIC PROCEDURES

Historical he Historical are objects responsible for the storage of tags value in disk. The storage can be made per time or event that must be specified to the data recording.

9.1. Historical Types The Historical can be created in two different ways: Continuouns, which store the data continually during the application running (e.g. recording of a cold chamber temperature every ficteen minutes) or in Batch, in case of lots (e.g. recording of separate oven temperatures according to production lot code and operator name). In the Batch, the data is stored with one or more references, associated to a header of the Historical in which a Batch can be found. In order to be started (StartBatchProcess()) or completed (FinishBathProcess()), the batch processes need special commands, via some script. To create or edit a Historical, we need ro select the item Historical in the Organizer. When a new one is created, it will be displayed below this item in the application tree.Selecting a specific Historical, its properties will be displayed in the right side of the tree.

Filename

It defines the file name to the current Historical.

Write time

It defines the frequency in which the data will be written in the Historical file.

Max Records

It defines a maximum number of registries to the Historical file. The Historical file is rotative, that means, when the data exceed the file size the registries will be displayed.

Enable Historic at application startup

It enables the Historical file writing from the start of the application running, according to the defined rate scan. Keeo this option disabled if you want to control (using Scripts) the creating of Historical data manually.

Batch process

It defines the Historical type as being Batch. When this option is enabled, a Header file (HDR extension) is created with the same name of the Historical file. The Header file keeps the information about each batch.

Network support

It enables the network support to the Historical, that is, it allows that the Historical be accessed (only for reading) by other Elipse applications in the Network, through a Browser or Report of the Historical Analysis type. This option also makes that each change in the Historical be immediately recorded, not allowing the operational System to perform a task “appointment” for later performance according to its running priorities.

After the historical type set up, we must add the tags in the Historical that will be stored, which is made in the tags table. To each added variable we must establich the field format, which can be: Type

When you choose the historical of Batch type, it will be created another itme in the Historical object, called Header that can be acessed via Organizer. Tags must be inserted in the header, and their values will be used to identify each one of the batch processes. Following the given example about the oven temoerature storage, where we would like to have a reference via lot code and operator name. So, there must be in your application two tags, code and operator, that will be inserted associated to the header item, and will have their value recorded in the batch beginning and, so you can identify it. The header data are registered in a file with HDR extension, with the same name of the historical data file name (e.g. If you informed HIST1.DAT as historical data file name, it will be created HIST1.HDR). There must exist in the header at least one tag, set as string field (text), so that the batch search can be made.

9.2. Historical Analysis Automatically, when a new historical is created, a historical Analysis object is obtained as a subitem. This object can be created separately in the report item, in order to perform different Analysis in the historical file that is being created, or even in other files that were not created by this application. In the Analysis, the objects plotter (that is the graphic formation) and Query, that deals with the data filter that will be applied in file to be visualized, are included.

MAKING RECORDING PER EVENTS

To perform the event data recording, you must disable the historical and start the application (option in the general page). So, the data will only be registered in a clear recording command, that must be done through a script. There are two different ways in scripts that can perform such operation, as listed below, supposing that Hist1 is the name of our historical example. Hist1.Open() Hist1.WriteRecord() Hist1.Close() Ou Hist1.enabled=1 Hist1.WriteRecord() Hist1.enabled=0 Basically, both perform the same operation, but the second one enables it to recording by time, while the enabled property is in 1. The writing command, WriteRecord(), obtains an updated value of the tags that are associated to the historical, creating another data line. TIME INFORMATION IN THE HISTORICAL

Each data registry that recorded has, as a patterm, a time information, that is the DataTime field, with 8 databytes (64 bits). Usually, when a data is recorded, the computer watch is consulted, and the obtained information is insert in that data line with an accuracy of 1 millisecond. You can stipulate, however, another date and hoursource. When clicking in the historical object in the Organizer, all the data field associated to it will be displayed below. The first one will always be the DataTime field. Clicking over this field, there will be the possibility to associate a tag or property, through the tag table. In this case, it can be associated to the property TimeStamp of any tag, in case the equipment with which there is information being exchanged, give support to the information sending from its local watch. So the data value recorded in the historical will not be the computer’s, but the other machine’s or equipment’s. HISTORICAL TREND

The screen object trend graphic, when previously set as historical trend, can visualize the historical data as well as the analisis. The objects associated to the trend, in this case, are not the tags themselves, but the historical fields that that are created when tgas are associated to the Historical.

H I S T O R I C A L

To choose data about the file to be associated to the trend, as well as the query manner, a Query page that can be acessed in the trend Advanced page or via Organizer – Screen – trend Object is created. The criteria settings are the same already described. The pens association to the field is done by clicking over the field Axle Y and/or Axle X in the Pens table, acessed by the Trend properties. Clicking over this field, alist with the historical field names will be displayed. To make the trend serach the data in the disk or to update its data, it is necessary, via some script, to run its function UpdateQuery(). If you want that to happen in the fix range, just insert this command in the script WhileRunning in the screen, informing its running time in milliseconds in the script. DATA COLLECTION MANNER OF THE TREND GRAPHIC

Through the Advanced page of the trend object we can determine the data collection manner. The Real Time first option does that the trend only collects data when the screen is open. When calling it again, it will be dispalyed clean. The second option causes the communication with its tag to take place independently of the screen; so, when you call it, the data will be already loaded. The thrird option, historical trend, allows to recover the data after the computer is off, or even to spread the same data recorded in disk the historical object. For that, the objects associated to the trend are not the tags themselves, but the historical field, as it has been already mentioned. INSERTING MARKS IN THE TREND GRAPHIC

Through the Pens page of the Trend object, we can associate marks ti the graphic, that can be vertical, horizontal or point (marks) lines. Each mark can be associated to a tag or property, or even be modified via script. BROWSER

The browser screen object has the same characteristics of the historical trend, but it shows the data of the text mode, not graphically. The browser does not update its data automatically, so you must run the function UpdateQuery() through some script when you want the update to take place. This object also to define some properties, such as line numbers that can be visualized, the line that is selected by the user, and son on, besides allowing each field format that will be visualized. The Browser also allows the visualization of the batch file, through the specification of the correspondent HDR file in the setting page.

Select the historical as batch. In the Header item that can be accessed via Organizer (inside the object Hist2), and associate the tag Code (that is the product code) such as a string (text) of 10 characters, and the property Application.Username, as we will see later, is the name of the user that is logging in the system, also as a string of the 10 characters. In the Tags table in the object Hist2, add the level and temperature tag. Task: To set the screen for bath dossier. Procedure: Insert 3 buttons in the bath screen of momentary type to run three basic tasks of the batch, that are star, finish, and restart. Such actions could be run via some signal coming from the field, although, for test effect, we eill do it manually through the buttons. In the tree buttons message key in “Start”, “Finish” and “Restart”. For the first one, create a script OnRelease, to the button, running the function Hist2.StartBatchProcess(). For the second one, Hist2.FinishBatchProcess(), and for th third Hist2.RestartLastBatch(). Task: To create a procedure in the same screen mentioned above, through the use of two Browser objects, a system for choosing Analysis by batch. Procedure: Insert in the bath screen, two Browser objects. In this example, the Browser will allow choosing the batch that we want to visualize through navigating in the HDR file. So, the first one must be associated to the file BATCH.HDR(FIND THE FILE BATCH.DAT, AND THEN CHANGE THE EXTENSION TO .HDR). In the Query page select no data criteria, and in the databases page, click in the Code field, specifying the word “Code” as label and in the field Application.UsrName field use the word “Operator”, then click in “Update”. In the second Browser (Browser2), do the association to the data file BATCH.DAT. In the settings page, choose the specific batch option.

Soon after that it will be pointer as search criteria to Analysis and for the Browser2, the batch whose code is being visualized by the operator. The object Browser does not have data update, that means the data file is not reconsulted automatically in regular ranges. This task is performed only when opening in the screen that has the object, or yet, through an update function called UpdateQuery(), that is present in the last line of our example. To the second button (Finish) we can add the function UpdateQuery() so that when completing the batch, the browsers will be update. In this case this button script would have the following setting: Hist1.FinishBatchProcess() Browser1.UpdateQuery() Task: To create in the same screen above a set point for keyboarding the product code. Procedure: Insert in the dosage screen a set point object, choosing in the format page the data with the text type (String). In the tags table associate it to the Tag Code.

Reports

He reports allow to perform the historical data, header and alarm printings, as well as the immediate data. There are four types of reports:



Text Report: It can make the data printing in the line and column format including the alarm files. It also allows the printing to filling in disk.



Graphic Report: It makes the graphic printing of the historical data, with the creation of subtitles.



Form: Use this option to print a form with any texts, momentary values of variables and bitmaps.



Historical Analysis: Screen report for visualization/printing of data in the disk. Use this report when you want to hav several analyses for each file, or even to remote data analysis, created by other applications.

All the reports have Query table for the specification of the data search range, and the Setting table to choose the data and batch files, if this option is enabled.

For the second bitmap, a script as follows: OnLButtonUp Report1.Print() PRINTING FILTERS

Together with the previous functions we can use the function AddFilter(field,valueLow,valueHigh) before printing, to use a filter in a specific field, together with the date, where the field is the historical field where you want to apply the filter; valueLow and valueHigh are the limit values, within which the print will be made. Consult the user’s manual for further information about this function. HOW TO PRINT A SCREEN

For that, just create a report of format type, inserting a bitmaps sole object, occupying the whole page extension. Name the bitmpa as Bitmap1, and the Form as Form1. Assume that you establish the screen ALT+S to perform the printing. Follow the next steps: Procedure: Go to the screen setting(if you want the print just in one page) or to the application (if you want in all screens). Choose the scripts page, New, type OnKeyRelease. Click in the capture button and press the keys ALT+S. Now the script is created In it, key in or capture through the App Browser the following functions: CaptureScreen("c:\teste.bmp") Form1.Bitmap1.bitmapName="c:\teste.bmp" Form1.Print() HOW TO CHANGE THE PRINTER AND RECONFIGURED THE REPORTS

This allows to load a recipe file in other variable set that are not field variables, allowing the preparation, in a separate process, of forms and so on, which will be used by the operator later. RETAINING TAGS IMPLEMENTING

This tip shows how to implement tags with persistent value, that is, the tag value is registered when it exists the application, and loaded when the application is run again. Create a new recipe model (name = recipe) and associate to it the tags and properties that you want to recors. In the script OnStartRunning of the Application, or even through any other procedure, in which you want to guarantee that the files will be recorded, add the following lines: IF Recipes.Recipes1.GetRecCount() > 0 Recipes.Recipes1.LoadRecipe(1) ENDIF In the script OnStopRunning of the Application, or even through any other procedure, in which you want to guarantee that the files will be recorded, add the following lines: IF Recipes.Recipes1.GetRecCount() < 1 Recipes.Recipes.CreateNewRecord("Persistent Tags") ENDIF Recipes.Recipes.SaveRecipe(1) By doing so, every time the application is finished the tags values are saved in the first register (SaveRecipe(1)) of the recipe file. When running the application, it is verified is loaded (LoadRecipe(1)).

The user with level 1 is considered a superuser, and when he is logged in he can, through the UserAdministration() function, create, change and remove the attributes of all users. By means of the same function, the other users can change their password by keyboarding the old password and by double validating the new password. The passwords and levels are recorded on an encrypted and independent file in the application directory. In order to the user be logged in the System, the function Login() must be forcingly executed. In case there were an user already logged in, this function will first provide a logout of the former user through the function Logout() and then a register of the new user.

Drill: Task: To create users and register them. Procedure: To create users with various access levels in the system screen except for the Openning screen, which will have free access to all users. Task: To create a Login procedure of the user in the Opening screen.

Databases

He Databases option of the Elipse Scada allows to create and manipulate one or more databases using the Windows ODBC, that allows the connection with an already created databasis or to create a new one from an assistant inside the software.

To create a new connection with a new table:

  

Choose the ODBC driver that you want to use; Set the connection and the file or directory name that contain data; Create each one of the fileds, choosing name, data type and syze.

In the Organizer the new table and its respective fields will be displayed, which can be changed using the special functions of the ODBC in the Scripts: Create a new connection with the already existing databases:



Create the databasis. In the Excel case, you must use the first line of each column as a field name;

 

Close the databasis;



In the Organizer, in Databases, choose Connect to an existing table, press the button New and choose the driver ODBC that you wish to use; Choose the directory where the databasis is;

The table and its respective fields must be displayed in the tree. Manipulate the data through the function ODBC Consult the Advanced manual for further information about Databases.

Remote Application

T

He Remote Application are used to connect two or more applications that are linked via local network, modem, serial cable or optical fiber. In order to use this resource, you need to specify at least one server station and one data customer, beside a network driver that will be responsible for the information exchange. The following communication drivers are available: DRIVER

DESCRIPTION

Ipx.dll / Ipx32.dll

It allows the communication on a network that uses the Novell® IPX/SPX protocol

Tcpip.dll / tcpip32.dll

It is the faster and most used driver. It is necessary to install a TCP/IP driver in your computer’s network.

Serial.dll / serial32.dll

It is used for serial or optical fiber communication between two computers; the physical environment must be full-duplex.

Dialup.dll / dialup32.dll

It is used for connection via dial line

The basic procedure for creating a remote application is by specifying a server application and one costumer. In the server application, you must set the network driver, whose procedures can be found in the user’s manual. In the customer application, you can start, for example, from the server application and to transform the normal tags (PLC, BLOCK, RAM, EXPRESSION, DEMO, …) in remote tags. Remember that when it is necessary to change the type of a tag we can use the tool “Change type to…”that accepts multiselection. The change can also be made with Block Elements and Remote Tags. When changing a tag to block element, the user informs in which Block the elements will be inserted; when changing a tag to remote, the user informs in which Remote Application or remote Tags Group the new

 Elipse Software

14-1

Elipse Scada

A P P L I C A T I O N

tag will be inserted; when changing the Block Element or Remote tag to another tag type, the user informs which one is the destiny tag group. Also, when a tag type is changed to Remote Tag, the Elipse copies the name and the full path of the original tag to the original tag name field in the Remote Tag. Besides that, when a tag type is changed, some properties or functions are verified to know if they will no longer exists after the type change, if that happens the change is aborted and a message is displayed to the user. Desides the remote tags, files can be transferred. The Elipse Scada uses a ressource that optimizes the file transference process, for it is able to transfer only the changes of the same file from one station to another. FILE TRANSFERENCE EXAMPLE

Here isn an example of application to the trasnference between two applications. Task: To create a specific screen that will display the transmission progress and its status. The button can call the screen called Transf_file. Script OnRelease Transf_File.Show() File_Remote1.GetFile("C:\Elipsew\Test.dat","C:\Elipsew\Test.dat") Task: To create a tag expression, with the name transf01, whose content will be and operation between two properties of the remote file. (File_Remot1.bytesDone/File_Remote1.totalLength)*100 This tag will display the bytes percentage that had already been transmitted in realation to the total. Task: to create the screen Transf_file to visualize the transference. Procedure: To create a graphic with horizontal bars associated to the tag transf01. To create another three text objects, with message zones, in order to visualize the following properties:  File_Remote1.Status:

It shows the connection status: 0 - Disconnected, 1 Connected or 2 - Connected.



File_Remote1.result: It shows the transference status: -1 without transference, 0 – default, 1 – sucessful.

 File_Remote1.totalLenght: It shows the file total bytes.

Optimization

O run the setting tasks in the shorter time possible and to obtain a better performance in the Application running, we listed here some useful tips:

1. Communication Speed: Try communicate with the data acquisition equipment in higher rates, once there are no communication problems. In general, dealing with serial communication, the Windows supports sommunication in 19200bps, which is preferred in relation to 9600bps.

2.

Communication Try number and Scripts OnCommError: In the communication driver settings, in the option Retry Default Communication its is not advisable to run a high number of tries, once the equipment presents continous communication errors, it is necessary to revise all the communication, from physical connections to the communication driver. Just raising the try numbers makes that each tag read be retried in number of the times before the software recognize the communication error, what degrades the communication performance as a whole 1) To ver:ify and manage with a better effectiveness the communication errors the Script OnCommError in the Driver object can be created, which will be called when any communication error takes place. 2) To manipulate the errors, some of the driver functions can be used, such as:

GetErrorInfo(param) It returns the information about the last occurred error. If stop=0, it returns the communication type that caused the error (see User’s Manual). If stop=1,2,3 or 4, it returnd the parameters N1 to N4 or B1 to B4 of the PLC tag or Block that caused the error. So, if in a PLC’s network where the parameters N1 or B1 represents the number of the PLC in the network, it is possible to know which equipment is with defaults.. AddFilter(strFilter) Add a communication filter in the Driver, disabling the readings or writings in tags that have parameters specified in the filter. Thus we can disable the communication with a

 Elipse Software

15-1

Elipse Windows

O P T I M I Z A T I O N

specific maintenance equipment, for instance, avoiding errors while while it is disconnected. RemoveFilter(strFilter) It removes the filter that was added with AddFilter(strFilter). Example: Assum that we are using the Modbus driver, whose parameter N1 indicates the PLC address in the network. A script suggestion would be as follows: To create a tag of RAM type called ERRO To create a script OnCommError in the communication driver: ERRO=Driver1.GetErrorInfo(1) Driver1.AddFilter(Str(ERRO,2,0)) MessageBox("Ocorreu um erro no PLC: "+StrZero(ERRO,2,0),"Communication error",0040h) 3.

Attributes “Enable reading by scan”, “Enable automatic reading” and “Enable automatic writing”: Try to correctly set these parameters in their tags. The normal procedure is that if a variable must be normally searched, the scan and automatic reading options must be enabled. If you want to directly control the writing and reading through the functions Read() and Write(), leave all the options disabled.

4.

Tags Advice: Elipse accomplishes optimization in the communication, in order to avoid that the variables be communicated with out reason, through the use of the properties advise, that indicates if any module (screen object, alarm, historical, report, script, and so on) is in need of the variable update value. Thus a tag thatis not being used by any object will not be read. If you wish the tag to be read independently of being used or not, you must, for instance, enble the alarm or evn to force its reading through the function Read() of the tag. In the case of the expression tags, always that a variable is changed, the tag will be evaluated again, if it is in the advise mode. On the contrary, it will only be evaluated when some module requires its value.

5.

How to set up screen objects to improve its performance: Objects such as trend graphics can perform the data collection in background and redraw the graphic in higher ranges, without lossing the collection. Thus the trend refresh time can be longer yhan the scan of the variables without damagingits content. Another consideration about the screen object is related to the animation object, when the transparent spends more processing time then the normal animation.

6.

Memory: The RAM memory quality necessary to good perfornance of its system depends on the application size. Usually, each application item spends around 2kbytes. To know the total item of your application, press the key

 Elipse Software

15-2

Elipse Windows

O P T I M I Z A T I O N

Ctrl+Shift+Alt+I. If your machine is limited, you can decrease the required memory quantity, working with lower resolution draw (16 or 256 colors), and creating animation only in the areas that will be animated.. 7.

Tie Optimization: If your do not need to align several ties, choose to separate them, so the script will have a better performance. Example:

Ex : For ...

For ... Next

Next Usually is slower than: For ... Next For ... 8.

Creating shortcuts for an Elipse application: The Elipse Scada 2.0 installment automatically registers the files with APP extension. Therefore, the Elipse Scada applications can be automatically run with a double click over the created application.To create an access icon (shortcut) in the desktop (work area), just find the program (in the explorer or file manager) in the directory or work folder and “darg it” to the wanted localization.

9. Y2K: The Elipse Scada registers the dates using a format that assures the

normal operation of the software to the next millenium without changes or charges.

10. Manipulating dates in the ELIPSE: The Elipse uses the JULIAN calendar

to manipulate dates, in such case the Y2K is avoided. You can use the properties day, monyh, year, hour, minute and second, or through the attribute currentTime. To show a date in any screen format, just insert a display associated to the property currentTime, and choose the format as Date/Time and click in the format button. Observer that the mentined parameters return the current date of the system, are constantly updated and could be replaced by a value (absolute date) of a databasis (ODBC).

11. Organizing the Object Tabs of the Elipse: By using the Tabs key it is

possible to move an object, such as a Setpoint, for instance, to next object of a series.

 Elipse Software

15-3

Elipse Windows

O P T I M I Z A T I O N

Initially, the shifting through the Tabs follows the object creation order in the screen. However, it is possible to easily change this order with a little trick; Select the objects in the desired Tab order. Press the "Bring to Front" or "Send to Back" buttons. 12. Faded Pictures (bitmaps): If you wish to transport an application to

another machine, and the picture fade, the following steps can be taken: 1) Open the explorer. 2) In the menu View, click over the option Options.In this dialog box, DESELECT the option HIDE MS-DOS files extensions to registered files. 3) Close the dialog box. 4) Return to the Elipse and reopen the application. The bitmaps must be displayed again.

13. Driver Files do not Appear: If you try set a new communication driver in

your application and you can not find a file, the reason must be the Windows Explorer that is set to hide files with DLL extension. To solve this problem, follow the next steps: 1) Open the explorer 2) In the menu View, click over the option Options or Folder Options 3) Select the View table, and in the option Hidden Files choose Show all files.

14. To show Video Images: The nnew video object allows the camera videos or

TV images ro be displayed, you need to have a video board with input for theses signal. The resolution is defined by the size of the object placed in the screen, with a frequency of 30 frames/second. To know more about the video use, read the User’s Advanced manual.
