you must complete steps 2 and 3 at a minimum before you can complete steps 6 or 7. The other steps can be completed in any order.

If you are creating a distributed application,

Differences between stand-alone and distributed applications are explained wherever they occur.

Start with a plan Before you start working with RSView, it is advisable to plan the application. For tips and information about how to plan an application, see Chapter 3, Planning an application.

Step 1—Set up the FactoryTalk Directory software This step applies to distributed applications only. For stand-alone applications, this step is completed automatically by the software. FactoryTalk Directory is software that allows the parts of an application to find each other on a computer, or on the network. It must be installed with the RSView SE components. 1–6

Q

RSView Supervisory Edition User’s Guide

For details about installing software, see the RSView Supervisory Edition Installation Guide. After you install RSView Supervisory Edition, and before you create an application, specify the name of the computer on which the FactoryTalk Directory server will run. Use the utility called Specify FactoryTalk Directory Location to set the name of the FactoryTalk Directory server computer. You will have to do this on every computer on the network that is to have access to the applications managed by that FactoryTalk Directory. For details, see “Setting up FactoryTalk Directory” on page 4-3. For details about how the FactoryTalk Directory software works, see page 5-6.

Step 2—Create and organize an application Create the application that operators will use at run time. Stand-alone applications include one HMI server. You can add one or more data servers to a stand-alone application. You cannot add areas or HMI servers to stand-alone applications. Distributed applications can consist of one or more areas, one HMI server per area, and one or more data servers per area. Stand-alone and distributed applications also contain all the components you create for operators and supervisors to use at run time (for example, graphic displays, alarms, data logging). For details, see Chapter 5, Working with distributed applications, or Chapter 6, Working with stand-alone applications.

Getting started

Q

1–7

Step 3—Add an HMI Server This step applies to distributed applications only. Stand-alone applications contain one HMI server that is created automatically when the application is created. The HMI server stores project components (for example, graphic displays), and serves these components to clients. The server also contains a database of tags, and performs alarm detection, and historical data management (logging). For details, see Chapter 5, Working with distributed applications.

Step 4—Plan how you will access data This step is necessary so you can complete steps 5, 6 or 7. To access data, you need to plan two things: „

„

how the application will communicate with the programmable controllers or devices on the network. once communications have been set up, how the application will access values in the programmable controllers or devices.

Setting up communications with devices

To access values in programmable controllers or devices, you need to „

„

know what kinds of controllers or devices you are using. plan how the application will communicate with the controllers or devices.

Communicating with ControlLogix® processors, or with large numbers of clients

For communications with ControlLogix processors, RSView provides built-in support via RSLinx® Enterprise. RSLinx Enterprise also 1–8

Q

RSView Supervisory Edition User’s Guide

provides better performance than RSLinx for RSView when communicating with large numbers of clients. RSLinx Enterprise cannot perform online tasks such as uploading and downloading RSLogix® 5000 files to a controller. If you need to provide this capability, use RSLinx for RSView. Next steps If you are using RSLinx Enterprise, create an RSLinx Enterprise data server in RSView Studio that points to the computer on which RSLinx Enterprise is running, and then create a device shortcut in RSLinx Enterprise. For more information, see step 5.

Communicating with Allen-Bradley® local and remote devices

For communications with Allen-Bradley local and remote devices, or with a small number of clients, RSView provides built-in support via RSLinx for RSView, RSLinx Gateway, and RSLinx Enterprise When to use RSLinx for RSView RSLinx for RSView provides restricted OPC® communications and FactoryTalk communications with Rockwell Automation PLCs and RSView SE Servers. You do not need to install an activation key to make RSLinx for RSView work provided you run RSLinx for RSView on the same computer as the RSView SE Server.

Use RSLinx for RSView when: „

„

the information being served to RSView SE Servers or RSView SE Clients is local. the RSLinx data server is installed on the same computer as the RSView SE Server.

When to use RSLinx Gateway You must install an RSLinx activation

Q

1–9

„

the RSLinx data server is installed on a computer separate from the RSView SE Server. You might want to do this for performance reasons, or to locate the OPC server physically close to the process.

You can have multiple data servers accessing topics in RSLinx in an application. Each data server must point at a different instance of RSLinx. If you are using RSLinx for RSView or RSLinx Gateway, create an OPC topic in RSLinx for RSView, and then create an OPC data server in RSView Studio that points at the computer on which RSLinx for RSView is running. For more information, see step 6. Next steps

You must install an RSLinx Enterprise activation to enable RSLinx Enterprise. Use RSLinx when:

Communication with third-party local and remote devices

For communications with non-Allen-Bradley local and remote devices, RSView supports OPC connections. OPC (OLE for process control) allows RSView to act as a client to other OPC servers. Set up the OPC server according to its manufacturer’s instructions, and then set up an OPC data server in RSView. For more information, see step 7.

Next steps

Accessing values in devices

Once an application can communicate with a device, you need to plan how the application will access the values in the device. To access values in a device, you can use data server tags, or HMI tags, or a combination of both. 1–10

Q

RSView Supervisory Edition User’s Guide

RSView conforms to the OPC Data Access (DA) 2.0 specification for information exchange among automation or control applications, field systems or devices, and business or office applications. RSView provides two ways to access values in programmable controllers or other devices: „

Direct access to the basic set of properties of all OPC-DAcompliant tags. To access these tags, in RSView Studio specify the tag’s address for any object you want to connect to data. For example, in a graphic display, you can type the tag’s address as part of an object’s expression.

„

Access to an extended set of properties through a special kind of tag called an HMI tag. These tags have additional properties for alarms, security, and data manipulation. To access these tags, set up an HMI server in RSView Studio. The HMI server’s Tags editor allows you to create HMI tags, and map them to physical addresses, or OPC tags in the devices on the network.

For details, see Chapter 8, Working with tags.

Step 5—Set up communications using RSLinx Enterprise Either complete this step, or step 6, or step 7, depending on what software you are using for communications. You don’t necessarily have to complete all of them. If the application is communicating with ControlLogix processors, set up communications in RSLinx Enterprise for best performance. You can have multiple data servers accessing device shortcuts in RSLinx Enterprise in a single application. Getting started

Q

1–11

To set up communications using RSLinx Enterprise 1.

Set up an RSLinx Enterprise data server in RSView Studio. The data server makes it possible to see the RSLinx Enterprise shortcuts in RSView.

2.

For each device you want to communicate with, create a device shortcut in RSLinx Enterprise.

When you browse for tags in devices, the device shortcuts appear in the tag browser, each representing a device. For details, see Chapter 7, Setting up communications.

Step 6—Set up communication using RSLinx for RSView Either complete this step, or step 5, or step 7, depending on what software you are using for communications. You don’t necessarily have to complete all of them. To set up communications using RSLinx for RSView 1.

For each device you want to communicate with, create an OPC topic in RSLinx for RSView.

2.

Set up an OPC data server in RSView Studio. The data server makes it possible to see the RSLinx OPC topics in RSView.

When you browse for tags in devices, the OPC topics appear in the tag browser, each representing a device. For details, see Chapter 7, Setting up communications.

Step 7—Set up communications for OPC data servers Either complete this step, or complete step 5 or 6. You don’t necessarily have to complete all of them. 1–12

Q

RSView Supervisory Edition User’s Guide

Set up communications for use with OPC data servers if you want to communicate with non-Allen-Bradley devices using a third-party OPC server. You can have multiple OPC data servers in an application. Each data server must point at a different OPC server.

To set up communications for use with OPC data servers 1.

For each device you want to communicate with, follow the manufacturer’s instructions to create an OPC topic in the OPC server.

2.

Set up an OPC data server in RSView Studio, and point it at the OPC server you set up in the previous step.

When you browse for tags in devices, the OPC topics appear in the tag browser, each representing a device. For details, see Chapter 7, Setting up communications.

Step 8—Create HMI tags If necessary, create HMI tags in any combination of these ways: „

Create tags as needed from the Tag Browser.

„

Create a complete tag database in the Tags editor.

„

„

Import an existing Allen-Bradley PLC or SLC database using the PLC Database Browser. Import an existing HMI tag database using the Tag Import and Export Wizard.

For details, see Chapter 8, Working with tags, and Chapter 9, Creating hmi tags. Getting started

Q

1–13

Step 9—Create graphic displays, trends, and alarm summaries Create graphic displays that represent the process. Build the graphic displays in a variety of ways: „

„

„

„

„

Use the RSView drawing tools to create graphic objects and text. You can create simple objects such as ellipses and rectangles, or create more complex objects such as trends and alarm summaries. You can also embed ActiveX objects. Drag and drop ready-made objects from the RSView libraries into a display. Import objects or entire images that have already been created in other drawing packages such as CorelDRAW. Import graphic information using the Graphics Import Export Wizard. Create graphic displays, trends, and alarm summaries in the Graphic Display editor.

For details, see Chapter 16, Creating graphic displays.

Step 10—Set up logging Set up activity, alarm, and data logging to have a record of what is happening when the system is running. Set up activity logging in the Diagnostics Setup editor. Set up alarm logging in the Alarm Log Setup editor. Set up data logging in the Data Log Models editor. All logged information is stored in a proprietary format for faster performance, but can be exported to an ODBC-compliant database while online, and then viewed with any ODBC-compliant reporting or analysis software, such as Microsoft Excel, or Seagate Crystal Reports. For data logging, you can also use the ODBC storage format to store data directly in an ODBC-compliant database. 1–14

Q

so you lock users into the RSView SE client. To set up user-level security, use the DeskLock Tool, included in the Tools folder. user level

For details, see Chapter 15, Setting up security.

Step 12—Customize and integrate RSView with other applications Use the RSView SE client object model with Visual Basic for Applications (VBA) code in graphic displays to customize and extend the capabilities of RSView. Some ways you might do this include: „

„

If you regularly require RSView data for use in programs such as Microsoft Excel, or PowerPoint®, consider using the RSView SE client object model and VBA display code to integrate these applications with RSView.

Using data with other applications

Validating operator input To validate operator input, use the RSView SE client object model with VBA. In VBA, create pop-up dialog boxes for data entry. Use VBA logic to validate the operator’s input, for example to ensure that the value an operator enters in a numeric input field falls within 10% of the value of another numeric input field.

Getting started

Q

1–15

Use the RSView SE client object model to populate VBA form objects with data, for use in graphic displays. For example, use list boxes or combo boxes in graphic displays to allow operators to select options such as recipe items.

„

Designing intuitive graphic displays

„

Manipulating the RSView SE client window

„

„

Write VBA code to arrange graphic displays based on the size of the RSView SE client window. This allows you to adapt an application dynamically to various screen desktop sizes and resolutions.

Send specific messages to the Diagnostics List and Diagnostics log file, to notify the operator of problems with VBA code. Sending custom messages to the diagnostics log file

The RSView SE client Object Model allows you to obtain security information about who is using the system, and to use the security information and events to control access to the system. For example, you can restrict a user’s access to a graphic display on a secured computer by creating code that displays the graphic display only when the user is logged in with a particular user name.

In the Application Explorer, right-click the component to be deleted.

2.

Click Delete.

Deleting a component deletes both the file reference and the physical file from disk.

Naming components When you name a component in RSView Studio, the file name for the component is created automatically on disk. The component name becomes part of the file name. The maximum number of characters for a component name varies depending on where the component’s file is saved on disk. RSView supports long file names. File names, including the path, can be up to 200 characters long. Exploring RSView Studio

Q

2–15

For example, the following path and file name contains 111 characters. The component name, Bakery Overview, (the name of the graphic display) is only 15 characters long, but could be as long as 104 characters. C:\Documents and Settings\All Users\Documents\ RSView Enterprise\SE\HMI Projects\Bakery1\ Gfx\Bakery Overview.gfx Component names can contain spaces. When using component names with spaces in commands, you do not need to enclose the component names in double quotes (“ ”), except when using the /P parameter with the Display command. For details about RSView command syntax, see Help or Chapter A, RSView commands. Names that conflict with commands or macros

To avoid problems when issuing commands and macros, do not give macros the same names as command. For example, assume you want to name a macro Display. To avoid confusion with the Display command, name the macro DisplayScreen instead. For details about how to use commands, see Appendix A, RSView commands.

Techniques for working in editors When developing an application, you will use many different editors, but they have many similar features and often require similar information. Knowing how to use these features saves time.

Using the context menus The Application Explorer and the Graphic Displays editor use context menus. In the Application Explorer, everything in the tree hierarchy, except the folders, have context menus.In the Graphics editor, the graphic display and the objects on a display have context menus. 2–16

Planning the layout of the network When planning a distributed application, pay careful attention to the layout of the network.

The Windows® domain or workgroup For applications that contain more than 10 computers, a domain controller is required. IMPORTANT

Do not run FactoryTalk™ Directory on the same computer as a Windows domain controller.

Applications that contain 10 computers or fewer, can be used in a Windows workgroup environment. In this case, all computers participating in a single application must be members of the same Windows workgroup, and all computers must have administrative rights.

IMPORTANT

If an application requires more than 10,000 tags and you are not using RSLinx® Enterprise for communications, install the OPC data server on its own, dedicated host computer for best performance. If you are using RSLinx Enterprise this is not necessary. RSLinx Enterprise is optimized to provide best performance for large numbers of clients (more than 10) and a large number of tags (more than 10,000) even if it is located on the same computer as the HMI server.

For details about data servers, see Chapter 7, Setting up communications. One or more development computers, running RSView Studio RSView Studio is configuration software for developing and testing machine- and supervisory-level human-machine interface (HMI) applications.

System requirements and installation For details about system requirements and installing software, see the RSView Supervisory Edition Installation Guide.

Planning redundancy In theory, the ideal redundant solution involves having at least one backup copy of everything—hardware, software, networks, and so on. In practice, this is seldom feasible, or even necessary. Before setting up redundancy, plan: „

„

„

which components in the system need to have backups—in other words, decide how much redundancy is needed. where (on which computers) to locate backup systems. the network layout, and calculate the processing load expected for each computer. This information can help you plan which parts of an application can share hardware.

You can set up redundancy for HMI servers and data servers. IMPORTANT

More than 2 HMI servers can be located on a single computer only for development purposes. When deploying an application, ensure that there are no more than 2 HMI servers per computer. For redundancy, only 1 HMI server per computer is permitted.

RSView Supervisory Edition provides built-in warm redundancy for HMI servers and data servers. Planning an application

Q

3–5

You can set up RSView Supervisory Edition to send alarm and data log information automatically to an ODBC-compliant database. You can set up an HMI server to buffer data locally if the database becomes unavailable. Set up redundancy separately for system activity logging, using the Diagnostics Setup utility.

Planning communications When planning communications, gather information about the types of controllers or devices in the plant, and the software that is available for communicating with them. This will help you set up one or more OPC servers. Next, plan how the devices on the network will communicate with the application. This will help you plan the number of OPC servers and data servers the application needs. Also, consider which systems need to be redundant in order to minimize disruptions to clients in the event that access to data becomes unavailable. This will help you plan the data server pairs you need. Finally, plan how you will access data in the controllers or devices. For many purposes you can access the values in controllers or devices directly, using tags provided by a data server in the application. For some purposes, however, you will need to set up an HMI tag database.

When to use HMI tags Use HMI tags when an application needs to provide extended capabilities, such as: „

„

3–6

Q

triggering alarms when tag values cross a specified threshold. scaling or offsetting a value before sending it to a programmable controller or device.

RSView Supervisory Edition User’s Guide

„

„

security features, to prevent unauthorized changes to a tag’s value. flexible addressing. HMI tags don’t require hard-coded physical addresses or device-specific variable names in an application. This lets you re-use an application with other devices, by changing the physical addresses to which tag names are mapped. Also, some controllers or OPC servers do not allow description tag names.

For details about setting up communications in RSView, see Chapter 7, Setting up communications.

Designing an HMI tag database Before creating an HMI tag database, take the time to plan it. A good design helps reduce the time required for maintenance, and can improve device-to-RSView response time.

Collect information Before creating an HMI tag database, collect this information: „

„

„

flowcharts of the processes (or process and instrument diagrams). a list of programmable controller data table or register addresses the application will be accessing. alarm requirements (for more detail, see “Planning alarms” on page 3-8).

Organize HMI tags Before creating HMI tags: „

develop naming conventions for HMI tags, choosing names that are familiar and logical to everyone. This makes troubleshooting easier. Planning an application

Q

3–7

group related HMI tags. Group tags in the way that makes most sense for the application. For example, group all similar devices, or group related areas of the plant floor.

„

When creating HMI tags, place related tags into folders. For greater organization, create nested folders. IMPORTANT

For optimum performance, do not place all the HMI tags in the root folder. It is also recommended that you limit the number of tags in a folder to less than 2000. HMI tags contained in nested folders do not contribute to the number of tags in the root of the folder.

Planning alarms Before setting up alarms, plan: „

what conditions will trigger alarms.

„

how operators will be notified of those alarms.

„

what information alarm messages should contain.

„

what actions will occur in response to those alarms.

„

which alarms will require additional actions that can be supplied using a macro.

Collecting data When planning data collection, design the system so only essential data is collected. Limiting data collection is important because collection activities require substantial processing power and generate significant traffic on the communication channel or network. Keep data collection requirements in mind when designing the layout of the programmable controller data tables and the tag database. Ideally, tag addresses should reference contiguous blocks of 3–8

Q

RSView Supervisory Edition User’s Guide

programmable controller data tables to reduce network traffic and optimize system response.

Designing graphic displays When designing displays, decide on the best way for users to navigate through them and develop a template to establish a common look and feel.

Develop a hierarchy of displays Well-organized graphic displays present information clearly and consistently and guide users through the system. Before designing individual graphic displays, plan an overall display hierarchy and plan how users will navigate through the hierarchy. A hierarchy is a series of graphic displays that provide progressively more detail as users move through them. A hierarchy should meet the needs of the various users, including managers, supervisors, and operators.

Create a template to ensure consistency It is possible to keep a consistent appearance among all the displays in a project by presenting the same pieces of information in the same place on each display. To ensure uniformity, develop a display with common elements that acts as a template. Each time you develop a new display, start with a copy of the template. For example, the template could contain: „

the company logo.

„

a title.

„

the date and time.

„

navigation buttons. Planning an application

Q

3–9

When designing displays, practising good visual design principles helps users and increases their efficiency. Aim for these important design principles: Consistency „

Be consistent in the use of symbols and color.

„

Be consistent with button labels and button placement. When you design several displays, place the same kinds of buttons in the same positions. For example, if there is a Start button in a certain position in one display, don’t put a Stop button in the same position in the next display.

Clarity

Use symbols that are easily recognizable. For example, use the conventional ISA symbols for tanks and valves. „

„

„

Don’t overload the screen with information. Use standard, clear terminology, and avoid abbreviations or acronyms that the user might not understand. Use colors with recognizable meanings. For example, in Europe and North America the colors red and green often mean stop and start. Keep color meanings consistent by assigning red only to Stop buttons, and green only to Start buttons. A fairly common vision problem is the inability to distinguish between red and green, so don’t rely on color alone to establish meaning.

„

3–10

Q

Use high-contrast color combinations, such as yellow on blue or dark text on light-colored backgrounds.

RSView Supervisory Edition User’s Guide

Usability „

„

If you’re designing for a touch screen, place important buttons where they will not be blocked by a pop-up window. The user can’t press a covered button. Also, ensure that buttons are large enough and spaced far enough apart for users to touch them easily, even when wearing work gloves. Ensure there is always a clear way to move between displays.

Using trends When planning trends, consider how they will be used. For example, will the trend be used to: „

analyze process trends?

„

monitor production efficiency?

„

archive process variables to ensure compliance with government regulations?

Based on such considerations, you can determine: „

which tags need to be plotted on the same trend.

„

which tags need to be plotted from a data log model.

„

which tags need to be plotted against time, or against another tag.

Designing a secure system When deciding on security requirements, consider if you should: „

restrict access to every component to prevent accidental changes, or whether limited access is enough.

„

restrict access to certain parts of the plant.

„

require everyone to log on. Planning an application

Q

3–11

Based on these considerations, you can set up security for individual users or groups of users. For example, you might want to set up groups of users, such as a manager group and an operator group.

Customizing the system, and integrating with other applications Using data from other applications If you regularly require data from programs such as Microsoft® Excel, or Microsoft SQL Server, consider using the RSView SE Client object model and display code with VBA to integrate these applications with RSView.

Customizing the system You can use the RSView SE Client object model to customize a system in the following ways: You can write an alarm detection algorithms using PLC logic, and then create events in RSView to respond to the algorithms.

Add custom alarm events

Validate operator input To validate operator input, use the RSView SE Client object model. In VBA, create pop-up dialog boxes for data entry. Use VBA logic to validate the operator’s input, for example, to ensure that the value an operator enters in a numeric input field falls within 10% of the value of another numeric input field.

Use the RSView SE Client object model to populate VBA form objects with data, for use in graphic displays. For example, use list boxes or combo boxes in graphic displays to allow operators to select options such as recipe items. Create custom operator forms

Write VBA code to arrange graphic displays based on the size of the RSView SE Client

window. This allows you to adapt an application dynamically to various screen desktop sizes and resolutions. Send custom messages to the Diagnostics log file Send specific messages to the Diagnostics List, and Diagnostics log file, to notify the operator of problems with VBA code.

The RSView object model allows you to obtain security information about who is using the system, and to use the security information and events to control access to the system. For example, you can restrict a user’s access to a graphic display on a secured computer by creating code that displays the graphic display on a workstation with a specific computer name, only when the user is logged in with a particular user name. Secure the system

Designing a multi-user system When an application is run by multiple users, behavior which is appropriate in a single-user environment might not be appropriate. For example, if a graphic display that is running on several clients contains a shutdown macro that stops a derived tags file, when the display is closed on one client, the shutdown macro will stop the derived tags file. This would affect the display on the other clients, because the derived tags file resides at the server. Design an application with contingencies like these in mind. For example, since all tags are global, do not store local information such as the last display shown, because all clients see the same tags.

Designing a system that is easy to deploy and maintain RSView Supervisory Edition includes tools and features to help you build ease of maintenance into an application in these ways: „

„

link parts of an HMI application to logic in programmable controllers using the OpenRSLogix5000 command. For example, by linking actions performed in RSView to Sequential Function Charts (SFCs) in RSLogix® 5000, you can help operators track the state of processes that are running in the plant. Because Sequential Function Charts are graphical representations of batch procedures, actions in RSView that are linked to RSLogix 5000 programs could also be used frequently by operators who monitor the progress of batch procedures. For details about the OpenRSLogix5000 command, see Help.

4–1

The FactoryTalk Directory software works like a telephone directory, or electronic address book, allowing the parts of an application to find each other on a computer, or on the network. The RSView SE clients in the illustration use FactoryTalk Directory to find out which computers are hosting RSView SE servers, and to gain access to graphic displays in the RSView SE applications running on the RSView SE servers. The RSView SE servers use FactoryTalk Directory to find RSLinx in order to gain access to data on the network devices (PLC-5 and ControlLogix® devices) and update the graphic displays. You can set up a network so that multiple applications share a single FactoryTalk Directory, or so that there are multiple FactoryTalk Directory computers for multiple applications. Multiple applications, one FactoryTalk Directory computer

FactoryTalk Directory can contain multiple applications, allowing you to have multiple automation systems on the same network. This would allow you to develop one application, while another is in operation. Alternatively, different applications can be in operation simultaneously, each controlling a different facility within a corporate network. All the computers participating in a distributed application share a common FactoryTalk Directory located on a network server. All of the computers that connect to an application must also be in the same workgroup if you are not using domains. Users can be members of different domains.

RSView Supervisory Edition User’s Guide

FactoryTalk Directory information used by the SE client before the FactoryTalk Directory became unavailable, is cached in memory. However, while FactoryTalk Directory is disconnected, you cannot modify an application’s structure—for example, you cannot add an area, a data server, an HMI server, or HMI server components. How RSView SE Clients respond to server disruptions

During server disruptions, users do not have to restart the RSView SE Client software to continue using the system. However, clients that have not accessed the application at least once before FactoryTalk Directory became unavailable, will not be able to access the application until FactoryTalk Directory service is restored.

About distributed applications In RSView Studio™ you can create two kinds of supervisory-level applications: stand-alone applications, and distributed applications. For a stand-alone application, all the software programs and application components must be located on the same computer, and there can be only one HMI server. For details about stand-alone applications, see Chapter 6, Working with stand-alone applications. In distributed applications, the software programs that allow a distributed application to run can each be located on a different computer on the network.

„

„

a list of Windows® users and their access codes (called privileges) for accessing the application and its contents. HMI servers. Each RSView Supervisory Edition™ application must contain at least one HMI server. For a distributed application you can set up a secondary host computer with a backup copy of the HMI server to provide server redundancy. areas, that allow the application to be organized and sub-divided into logical or physical divisions. You can also use areas to separate servers that contain the same names, for example two HMI servers running projects that contain the same set of displays or tags. data servers, that allow clients to access information in programmable controllers, devices, and other data servers that comply with the OPC-DA 2.0 specification, without the use of HMI tags. You can set up a redundant pair of host computers for each data server. Examples of the information provided by data servers are: „

Q

components such as graphic displays, HMI tags, and data log models, created in RSView Studio.

RSView Supervisory Edition User’s Guide

Key concepts Areas All applications have one system-defined area called the application root area. The application root area has the same name as the application, and contains the User Accounts and Secured Commands editors. The application root area can contain an HMI server, or one or more data servers. In distributed applications, you can create additional areas in an application. Each area can contain one or more sub-areas, and one or more data servers. Each area or sub-area can contain only one HMI server. In distributed applications, you can use areas to divide an application into manageably-sized, logical parts, or to organize it in a way that makes sense for the process it is controlling. An area might represent a portion or stage of a process, or a region within the process facility. For example, an automotive plant might be divided into areas called Press and Fabrication, Body Shop, Paint Shop, Engine and Transmission. A bakery might be divided into areas called Ingredients, Mixing, Baking, and Packaging. Alternatively, a plant with identical production lines might be divided into areas called Line 1, Line 2, Line 3, and so on. This would allow you to add new, identical production lines to the application by copying HMI server projects into new areas. The home area

In distributed applications, the home area is the area in which an application component (e.g., a tag or display) is located. When you refer to an application component, but don’t specify the area in which it is located, RSView uses the home area to locate the component. Working with distributed applications

Q

5–3

For example, if you create a reference to a tag on a display but do not specify its area, RSView assumes that the tag’s home area is the same as the display’s. If the tag does not belong to a data server or HMI server in the display’s home area, an error will occur when the display is run. Absolute and relative references

When you refer to an application component, for example a graphic display, you create a reference to it. Use absolute or relative references when building commands, or when connecting graphic objects to tags. Absolute references point directly at a specific component by referring to the component’s name and the area (or areas, in the case of nested areas) that contain it. Absolute references are a way of referring to a specific component in a specific area.

For example, an absolute reference to a display called Detail in an area called AssemblyLineNorth is /AssemblyLineNorth::Detail. IMPORTANT

An absolute reference to an application’s root area does not include the application’s name, even though the name appears in the root area in RSView Studio.

Relative references

point at a component relative to the current

server or area. For example, a relative reference to a display called Detail is simply the display’s name: Detail.

Using absolute and relative references Assume the display called Detail, mentioned above, contains an absolute reference to a tag called /AssemblyLineNorth::Speed, and a relative reference to a tag called Temp. The relative reference is simply the tag’s name: Temp. If you copy the Detail display to an area called AssemblyLineSouth the display will still use the tag /AssemblyLineNorth::Speed because you 5–4

Q

RSView Supervisory Edition User’s Guide

referred to it using an absolute reference. However, the tag called Temp will now refer to /AssemblyLineSouth::Temp because you referred to the Temp tag using a relative reference. If the Temp tag does not exist in the AssemblyLineSouth area, an error appears in the FactoryTalk Diagnostics List. Use absolute references when you want to ensure that a specific component is used, regardless of where it is referenced from. Relative references can be used, for example, in an application for a plant that has identical production lines. The application could have multiple areas, each representing one of the production lines, with the same component names in each area. For details about areas, see page 5-3. Syntax

Precede area names with a forward slash (/). Also separate area names from other area names, with a forward slash. Separate area names from component names with two colons (::).

Example: Using the Display command with absolute and relative references in distributed applications Assume that a graphic display called Overview appears if the operator presses a button on a graphic display. To show the graphic display called Overview, use the Display command in the button’s press action, as follows: „

„

To create an absolute reference to the display called Overview in the area called Baking, type Display /Baking::Overview. To create an absolute reference to the display called Overview in the area called Packaging, type Display /Packaging::Overview. Working with distributed applications

Q

5–5

„

To create a relative reference to the display called Overview in the area from which the Display command was issued, type Display Overview.

More information and examples

For information about using absolute and relative references with tags, see “Using tag references” on page 8-15. For information about using absolute and relative references with commands, see page A-6.

HMI server, HMI project, HMI client HMI servers are software programs that supply information to clients

when they request it. HMI servers store HMI project components (for example, graphic displays), and serve these components to clients. Each HMI server also manages a database of tags, and performs alarm detection, and historical data management (data logging). HMI projects contain displays, data log models, alarms, HMI

tags and

other services. HMI projects are loaded by HMI servers. HMI clients are software programs that obtain information from, or write information to HMI servers or data servers. RSView Studio, the RSView Administration Console, and the RSView SE Client are all HMI clients.

FactoryTalk Directory FactoryTalk Directory is software that allows the parts of an application to find each other on a computer, or on the network. For example, to access graphic displays on HMI servers in the application, HMI clients use FactoryTalk Directory to find out which computers on the network are hosting HMI servers. 5–6

Q

RSView Supervisory Edition User’s Guide

All the computers participating in a particular application share a common FactoryTalk Directory located on a network server. If FactoryTalk Directory becomes unavailable while an application is running, the application will continue to run correctly because a copy of the information provided by FactoryTalk Directory is stored locally on each computer that is connected to the FactoryTalk Directory computer. RSView SE clients that are connected to the application will be able to continue running without restarting the system. Clients that were not connected to the application before the FactoryTalk Directory went down, will not be able to do so until service is restored. For details about FactoryTalk Directory, see Chapter 4, Setting up FactoryTalk Directory.

Redundancy In process monitoring and control automation, redundancy refers to the ability of the system running the process to continue to work correctly when one or more parts of the system become unavailable, or fail, by setting up pairs of the critical systems components such as data servers, on paired computers. One of the servers acts as the primary server, and the other is the secondary, or backup, server. How RSView SE clients respond to server disruptions

During server disruptions, users do not have to restart the RSView SE client software to continue using the system. Once the system has switched to the secondary HMI server, or data server, RSView SE clients continue functioning normally. About HMI-server redundancy

You can set up redundant operation for HMI servers to provide minimal disruption of system operation in the event that clients lose service from a server, for example because of network or computer failures. Working with distributed applications

Q

5–7

For information about how HMI-server redundancy works, see “Redundant HMI servers” on page 25-8. The operational status of HMI servers

There are four possible states for an HMI server: „

Active means that the server is running, and able to serve data to clients that connect to it.

means that the server is running, and will replace the active server if the active server fails.

„

Standby

„

Out of service

means that the server has been created, but cannot

be contacted. „

applies to the secondary server only. Unknown means that the secondary server has not been created yet. Unknown

You can see the operational status of an HMI server by clicking the General tab in the HMI Server Properties dialog box. You can also use VBA code on the client to determine the status of HMI servers. For details about loading the primary server automatically when Windows starts, see “Starting the HMI server when the operating system starts” on page 5-17. For details about loading the server manually, see “Starting and stopping HMI server components manually” on page 26-10. File synchronization

While the server is active, changes made to files (for example, configuration files, or log files) are not automatically synchronized on the secondary server.

5–8

Q

RSView Supervisory Edition User’s Guide

If synchronization is required, the files must be synchronized manually after the changes are made. You can do this by copying the files using Windows Explorer. For details, see “Synchronizing servers and projects” on page 26-12. Alarm state synchronization

For alarm states to be synchronized properly, the clocks on the primary and secondary HMI servers must be kept synchronized to a time server. If the clocks on both computers are not synchronized, when fail-over occurs multiple alarms or inconsistent information might be displayed in an alarm summary. About data-server redundancy

You can set up redundant operation for data servers to provide minimal disruption of system operation in the event that clients lose service from a server, for example because of network or computer failures. For information about setting up redundancy for OPC data servers, see “Setting up OPC data server redundancy” on page 7-9. For information about setting up redundancy for RSLinx Enterprise data servers, see “Setting up RSLinx Enterprise data server redundancy” on page 7-12.

You cannot attach to an existing HMI server if the HMI server is used in another application.

When to use additional HMI or data servers A distributed application does not require more than one HMI server or data server, but there are circumstances in which it is helpful, for example to provide redundant operation for HMI servers or data servers at run time, or to allow different integrators to work on different HMI servers without worrying about name collisions or needing to integrate all the files later. Adding HMI servers or data servers for redundant operation

You can set up redundant HMI servers or data servers to enable an application to use a secondary server in the event that the primary server goes out of service. You must set up redundancy separately for each HMI server or data server in an application. „

For details about adding HMI servers to an application, see page 5-14. Working with distributed applications

„

„

For details about adding OPC data servers to an application, see page 7-7. For details about adding RSLinx Enterprise data servers to an application, see page 7-11.

Adding HMI servers or data servers for load balancing

Over time, an HMI project might increase in size, or the number of clients connecting to the HMI server or data server might increase to the point where the computer running the server becomes overloaded. If this happens, install another HMI or data server on a different computer and then move some of the HMI project components, or some of the OPC server tags, to the new server. This distributes the processing load across computers more effectively and provides better performance. IMPORTANT

More than 2 HMI servers can be located on a single computer only for development purposes. When deploying an application, ensure that there are no more than 2 HMI servers per computer. For redundancy, only 1 HMI server per computer is permitted.

Server restrictions Server Names

The names of HMI servers are stored by FactoryTalk Directory, and are not deleted, even if you remove an HMI server from all applications in which it is used and then delete the HMI server’s project files. The name of every HMI server must be unique. This means that: „

5–14

Q

You cannot re-use a name for an HMI server, even after you have deleted the HMI server.

RSView Supervisory Edition User’s Guide

If multiple users share the same FactoryTalk Directory, the names of all HMI servers created by all users must be unique. Similarly, if multiple applications share the same FactoryTalk Directory, the name of each HMI server in each application must be unique.

„

Number of servers

In distributed applications, each area can contain only one HMI server, and an application can contain no more than two HMI servers. Each computer can have no more than one HMI server running on it. If a distributed application needs more than one HMI server, install each one on a separate computer. IMPORTANT

More than 2 HMI servers can be located on a single computer only for development purposes. When deploying an application, ensure that there are no more than 2 HMI servers per computer. For redundancy, only 1 HMI server per computer is permitted.

select a startup type for the HMI server. change the name of the computer on which the HMI server is running. set up server redundancy and specify the name of the second computer that will host the redundant HMI server. select the components that will run when the HMI server starts up. specify macros that will run when the components are shutdown, and, if redundancy has been set up, when the server goes into standby mode or becomes active.

To open the HMI Server Properties dialog box 1.

5–16

Q

In the Application Explorer in RSView Studio or the RSView Administration Console, right-click the HMI server and then click Properties.

RSView Supervisory Edition User’s Guide

You must set up the properties of each HMI server separately in a distributed application. For details about filling in the fields of the HMI Server Properties dialog box, see Help.

Specifying how the server starts up You can set an HMI server to start up when the first client connects to it (on demand), or when the operating system initializes. After an HMI server has finished starting, it is said to be loaded. After an HMI server has finished stopping, it is said to be unloaded. Use on demand only for developing a system. In the run time environment, the HMI server should start when the operating system starts to ensure that no alarms or logged data is missed. Starting the HMI server when the operating system starts

You can set an HMI server to be loaded when Windows starts. This option is for normal use at run time, and is required if you want to set up redundancy for the HMI server. This option allows clients to connect quickly, and ensures that the HMI server can be brought back to normal operation automatically if the computer on which it is running is restarted. If you are setting up redundancy for an HMI server, and choose not to run components when the servers start up, you can specify macros to start the components only when the server is the active server. For details about creating macros, see Chapter 22, Creating macros.

Working with distributed applications

Q

5–17

The HMI server can be unloaded by changing the Startup type to On demand, and then closing all clients, or by using the RSView SE Service Manager IMPORTANT

After changing the start type, you must restart the HMI server computer for the change to take effect.

Because the HMI server runs as a service, users do not have to log into Windows to make the HMI server run. Starting the HMI server when the first client connects to it

You can set up the HMI server to load on demand. This means that the HMI server is loaded when the first client accesses the HMI server project, and is unloaded when the last client is closed. When the HMI server is loaded, the user can edit the server’s HMI project using RSView Studio, and connect clients to the HMI server. A client can be RSView Studio, the RSView Administration Console, or the RSView SE Client. An unlicensed HMI server can only be started on demand.

Changing the name of the host computer In the General tab of the HMI Server Properties dialog box, the box labeled Computer hosting the server, displays the name of the computer the HMI server is running on. To change this to another computer, a copy of the HMI server has to exist on the computer that is going to be the host.

5–18

Q

RSView Supervisory Edition User’s Guide

Setting up HMI server redundancy To minimize disruptions to clients if the primary HMI server fails, set up a redundant HMI server. In RSView, the redundant server is called the secondary server. When the primary HMI server becomes available again, the system automatically switches back to the primary server. The settings you specify on the Redundancy tab are saved with the application, and are the same for both primary and secondary HMI servers. You do not need to specify different settings for the computers that are hosting the primary and secondary servers. Specifying server redundancy

In the Redundancy tab of the HMI Server Properties dialog box, click the Provide redundancy using a secondary server, check box to enable redundancy for this HMI server. Clear this check box to disable redundancy for this HMI server. This option is available only if the HMI server startup type is set to Load and run startup components when operating system initializes. For details about the HMI server’s startup type, see page 5-17. Selecting the secondary host computer

In the Redundancy tab of the HMI Server Properties dialog box, type

the name of the computer hosting the secondary HMI server. To browse for the name of the computer, click the Browse button. For information about the steps required to set up redundant components in an application, see “Planning the layout of a redundant system” on page 25-12.

Selecting the HMI server’s startup and shutdown components In the Components tab of the HMI Server Properties dialog box, select the check box for each of the items you want to run when the HMI server runs. Where required, specify the name of a component. Use the Components tab to select: „

which components will run when the HMI server starts.

„

which macros will run when the HMI server shuts down.

„

which macros will run when switching to the secondary HMI server, or back to the primary HMI server.

For details about the options in the Components tab, see Help. The HMI server can be started automatically when the operating system starts, or manually. For details about starting the HMI server manually, see page 26-11. IMPORTANT

The order in which items appear in the Components tab is not the order in which items will run. If you have created an HMI server that has components that must start in a particular order, create a macro that will run when the HMI server starts.

Running a macro when the HMI server becomes the active HMI server

The macro that runs when the HMI server becomes active is called the On active macro. An HMI server can become active if another HMI server fails, or if it is a primary server at startup time. Any macro can be used as the On active macro. If you have not set up a secondary server in the Redundancy tab, the On active macro is not available. 5–20

Q

RSView Supervisory Edition User’s Guide

Running a macro when the HMI server becomes the standby HMI server

The macro that runs when the HMI server switches from being active to being on standby is called the On standby macro. For example, when the system switches back from the active secondary HMI server to the primary HMI server after the primary server has been restored to operation, the primary server first goes into On standby, and then into Active. When the primary server becomes active the secondary goes into On standby. The On standby macro will not run if the active HMI server fails and is unable to run the macro, for example if the power to the computer fails. Any macro can be used as the On standby macro. If you have not set up a secondary server in the Redundancy tab, this option is not available.

Setting up redundant HMI servers To set up a redundant HMI server, complete these steps: 1.

Install the RSView SE Server software on the computer you want to host the secondary HMI server. For details, see the RSView Supervisory Edition Installation Guide.

2.

Copy the HMI project files from the computer hosting the primary HMI server to the computer hosting the secondary HMI server. For details, see “Moving HMI project files” on page 26-6.

3.

In RSView Studio on the primary computer, open the HMI Server Properties dialog box for the primary HMI server.

Some contain tag databases of their own, like the tag database in an HMI server, while others simply reference the tag databases or addresses that exist in controllers themselves, as is the case with RSLinx® and ControlLogix®.

„

components such as graphic displays, HMI tags, and data log models, created in RSView Studio.

For details about distributed RSView Supervisory Edition™ applications, see Chapter 5, Working with distributed applications.

Using references in stand-alone applications When you refer to an application component, for example a graphic display, you create a reference to the component. Stand-alone applications make use of relative references to refer to application components, for example tags, or graphic displays. Relative references point at a component relative to the current application. Working with stand-alone applications

Q

6–3

For example, a relative reference to a display called Detail is simply the display’s name: Detail.

Example: Using the Display command with relative references in stand-alone applications Assume that a graphic display called Overview appears if the operator presses a button on a graphic display. To show the graphic display called Overview, use the Display command with a relative reference to the name of the display: type Display Overview.

Creating an application Stand-alone applications consist of the application root area, one HMI server, and if needed, one or more data servers. Once you have created the application, use the editors in the RSView Studio Application Explorer to create application components, such as graphic displays. To create a stand-alone application 1.

Types of data servers In RSView Supervisory Edition™, you can create two kinds of data servers: „

an OPC data server.

„

an RSLinx Enterprise data server.

If you are using RSLinx for RSView, RSLinx Gateway, or a third-party OPC data server for communications, create an OPC data server. If you are using RSLinx Enterprise for communications, create an RSLinx Enterprise data server. An OPC data server provides support for RSLinx for RSView, RSLinx Gateway, or any data server that conforms to the OPC-DA 2.0 standard. RSLinx for RSView and RSLinx Gateway provide enhanced support for Rockwell Automation programmable controllers and devices.

RSLinx for RSView does not require an activation key provided it is installed on the same computer as an RSView SE Server, and is serving data to FactoryTalk clients only, such as RSView SE Client or RSSQL. RSLinx Gateway can be installed on any computer, but requires an activation key to serve data to remote, third-party OPC clients. is for use with RSLinx Enterprise, and provides best performance when communicating with ControlLogix processors or with large numbers of clients.

Because RSLinx for RSView and RSLinx Enterprise can be set up to communicate with multiple types of controllers simultaneously, you might not need a separate data server for each controller. „

„

If you have set up RSLinx to communicate with all the controllers in an application, you only need one data server that you set up with an OPC topic or device shortcut for each controller. If you have set up multiple copies of RSLinx, each of which communicates with a different controller or network, you will need to set up a data server for each copy of RSLinx you have running.

For details about setting up communications in RSLinx for RSView, see Getting Results with RSLinx, or see Help for RSLinx for RSView. For details about setting up communications in RSLinx Enterprise, add an RSLinx Enterprise data server to an application, open the Communications Setup editor, and then click Help.

Tags and the HMI tag database A tag is a logical name for a variable in a device or in local memory (RAM). For example, a tag can represent a process variable in a network device.

When to use HMI tags Use HMI tags when an application needs to provide extended capabilities, such as: „

„

„

„

security features, to prevent unauthorized changes to a tag’s value. flexible addressing. HMI tags don’t require hard-coded physical addresses or device-specific variable names in an application. This lets you re-use an application with other devices, by changing the physical addresses to which tag names are mapped. Also, some controllers or OPC servers do not allow description tag names.

For details about setting up communications in RSView, see Chapter 7, Setting up communications.

Data server tags, HMI tags, and their attributes RSView® conforms to the OPC ® Data Access (DA) 2.0 specification for information exchange among automation or control applications, field systems or devices, and business or office applications. The OPC-DA specification calls tags ‘data items’. RSView provides direct access to the basic attributes of all OPC-DA-compliant tags through a data server. In the RSView documentation, the tags you access through a data server are called data server tags. RSView also provides a tag with additional properties for alarms, security, and data manipulation. These are called HMI tags and are created using the Tags editor in RSView. An application can use a mix of HMI tags and data server tags. To use data server tags such as those found in ControlLogix® and other OPCcompliant devices, provide a direct reference to the tag’s location wherever the application is to use the data. Tag-related limits

Graphic displays can contain a maximum of 3000 animations that reference tags (HMI tags and data server tags). 8–2

Q

RSView Supervisory Edition User’s Guide

Each HMI server in an application can have up to 40,000 HMI tags that have alarms. Of these alarm tags, 10,000 can be analog HMI tags. IMPORTANT

If an application has more than 10,000 tags and does not use RSLinx® Enterprise for communications, place the OPC data server on its own, dedicated host computer for best performance. RSLinx Enterprise is optimized to provide best performance for large numbers of clients (more than 10), and tags (more than 10,000), even if it is hosted by the same computer as the HMI server.

Basic steps for using tags To use tags: 1.

Type the name of the tag or browse for it, anywhere you plan to connect an object to live data at run time. For example, you can set up a graphic object that represents a vat on a production line so that at run time it will show the level of the vat. To do this, set up Fill animation for the object using the name of a tag that is updated by a network device that monitors the level of the vat. At run time the value of the tag will determine the fill level of the graphic object.

2.

If the tag does not already exist, create it: To use a new data server tag, (for example, in a device), create it in the device or OPC server. For example, in a ControlLogix device, create the tag using RSLogix® 5000 programming software. To use new HMI tags, create them in the Tags editor. For details, see Help.

Working with tags

Q

8–3

Browsing for tags

If you don’t know the names of tags, you can browse for them. You can browse while online and connected to a device, or you can browse for tags from an offline file, for example a PLC program file. To browse for tags, use the Tag Browser. For details, see page 8-7. Using tag names that don’t exist

You can type the name of a tag that doesn’t yet exist. If you do this, when you create the tag, and everywhere you use its name, make sure that you spell the tag name consistently.

Using data server tags For some uses in an application, data server tags can offer advantages over HMI tags. For example, using direct references to tags in devices, or to tags located in an OPC server’s database, can eliminate the need for duplication or provide access to complex data types.

Eliminate duplication Using data server tags lets you add, modify, or delete tags in a device without having to duplicate the changes in the HMI tag database.

Access to complex data Some devices, for example ControlLogix processors, support complex data types such as arrays and structures. A controller can have structures that contain hundreds of member elements. Referencing tag values directly eliminates the need for creating an HMI tag for each member. 8–4

Q

RSView Supervisory Edition User’s Guide

Setting up data server tags To use data server tags: 1.

Create the tag in the OPC server, or processor, or use an existing tag in the processor. For information about creating tags in OPC-DA servers that have their own tag database, see the documentation provided with the OPC-DA server. For information about creating tags in a ControlLogix processor, see the programming software documentation for ControlLogix.

2.

Create a data server in RSView, if the application doesn’t already have one.

3.

Anywhere you need to access a tag’s value, map an application component to the tag. For example, map a tag to a graphic object, or add the tag to a data log model. At run time, the tag’s value is passed to the component it is mapped to.

Using HMI tags Use HMI tags for triggering alarms and where you need to manipulate data or secure the values in a device.

Triggering alarms In RSView, HMI tags provide the only method for triggering an alarm when a tag has a certain value. An alarm occurs when something goes wrong. It can signal that a device or process has ceased operating within acceptable, predefined limits or it can indicate breakdown, wear, or a process malfunction. For more information about alarms, see Chapter 11, Creating alarms. Working with tags

Q

8–5

Securing tag or device values Only HMI tags can be used to secure tag or device values. You do this by assigning a security code to a tag. To prevent users from changing a value in a device, create an HMI tag for the device’s address, and then assign security to the tag. For information about assigning security codes to tags, see Chapter 15, Setting up security.

Manipulating data Use HMI tags if the data server you are using does not support scaling or offsetting a value, or setting minimum or maximum limits on a value (that is, providing a range of values). Scale, offset, and minimum/maximum values for analog HMI tags, can be specified in the Tags editor. Scale and offset

Use scale and offset to modify the raw data that comes from the network device before it is saved in the computer’s memory, or to modify a value specified in RSView before it is written to a device or data server Scale is a multiplication factor—the value from the device is multiplied by the scale. Offset is a fixed value—after the value from the device is multiplied by the scale, the offset amount is added. Minimum and maximum

HMI tags allow you to set the minimum and maximum values that can be written to the network device or data server. These values do not affect what is read from the device or server. 8–6

Q

RSView Supervisory Edition User’s Guide

For example, if you specify a minimum of 0 and a maximum of 100, RSView would be able to read a value of 200 from a device and store it in memory, but would not be able to write this value to the device.

Storing values in RSView’s memory A memory tag can be used to store values without the need for an attached or accessible device. For example, you can use memory tags: „

to store the result of a calculation.

„

temporarily, for example, to act as a counter or index.

„

to maintain information about the system’s current state, for example, which graphic display was last displayed.

For information about creating memory HMI tags, see Help.

Setting up HMI tags To set up HMI tags: 1.

Create an HMI server if the application doesn’t already have one. Each HMI server contains one tag database.

2.

In the tag database, create memory tags, or for device tags, map each tag name to an OPC or DDE address.

3.

In graphic displays, alarm summaries, or anywhere else you plan to access a tag’s value, map an object to a tag. At run time, the tag’s value is passed to the object.

Browsing for tags To use a tag, you can type its name and path, or browse for it using the Tag Browser. The way to open the Tag Browser depends on where you are in RSView. Working with tags

For information about creating and editing HMI tags, see Chapter 9, Creating hmi tags. For information about importing tags from a PLC database, see page 9-12. 8–14

Q

RSView Supervisory Edition User’s Guide

Using tag references When you type a tag name, you are creating a reference to the tag. For example, you might refer to a tag called FanRunning to obtain its value for animating a graphical representation of a fan in a graphic display. The Tag Browser composes references to tags automatically, using correct syntax. You can also create references to tags manually, by typing the tag name and, optionally, its path. In distributed applications you can refer to a tag using an absolute reference or a relative reference. In stand-alone applications you only use relative references.

Absolute references Absolute references are a way of referring directly to a specific tag in a specific area by providing the tag’s name and the path to it. For example, /Cooling/Fans::Extractor is a reference to an extractor fan in the Fans subarea of the Cooling area. Use absolute references when you want to ensure that you are referring to a specific tag in a specific location.

Relative references Relative references point at a tag relative to the current server or area. For example, Extractor is a reference to an extractor fan in the current area. Relative references are useful if tag names are all the same, but they are in different areas. This might be the case if you expect to clone identical areas, for example to represent identical production lines in a plant. For more information about areas, see page 5-3. Working with tags

Q

8–15

The home area The home area is the area in which a component (for example, a graphic display) is located. The home area is relevant only for distributed applications. For example, if you create a graphic display in the Cooling area, and add a relative reference to a tag (for example, FanStart), RSView looks for the tag in the home area of the graphic display (Cooling). If the tag does not belong to a data server or HMI server in the home area, an error will occur when the display runs. If the tags you select are in the home area, the Tag Browser automatically uses relative references. If the tags are not in the home area, the Tag Browser uses absolute references.

The home area appears in bold type.

Logging tag values Any tag value can be logged by the RSView data logger. The data logger uses data log models to determine which values to log. For a tag to be polled and its values logged by the data logger, the tag needs to be included in a data log model, and the model needs to be started at run time. For details, see Help, or Chapter 13, Using data logging.

For details, “Using HMI tags” on page 8-5. Use the Tags editor in the HMI Tags folder in the RSView Studio™ Application Explorer, to create and edit HMI tags. In a distributed application, you can edit a tag database locally (on the same computer) or remotely (from a different computer).

9–1

HMI tag types An HMI tag database can contain the following types of tags: Tag

Type of data stored

Analog

Range of values. These tags can represent variable states such as temperature or the position of rotary controls.

Digital

0 or 1. These tags can represent devices that can only be on or off, such as switches, contacts, and relays.

String

ASCII string, series of characters, or whole words (maximum of 82 characters). These tags can represent devices that use text, such as a bar code scanner that uses an alphanumeric product code.

System

Information generated while the system is running, including alarm information, system time and date, and so on. RSView creates system tags when it creates an HMI project. The system tags are stored in the folder called System in the tag database. You cannot edit system tags. You can use system tags anywhere you would use any other type of tag.

Data sources for HMI tags When defining an analog, digital, or string HMI tag, you specify where it receives its values. This is called the data source. The data source can be Device (external) or Memory (internal). Device

An HMI tag with Device as its data source receives its data from a source external to RSView. The data can come from a programmable controller or other device via RSLinx®, or from another OPC ® or DDE data server. 9–2

Q

RSView Supervisory Edition User’s Guide

Memory

An HMI tag with Memory as its data source receives its data internally from RSView. A memory tag can be used to store values internally. Retentive memory tags You can specify that a memory tag’s value be retained even if an HMI server is shut down.

In a distributed application, if RSView Studio or RSView SE clients are running, a memory tag’s value can be changed at any time prior to shutting down. The next time the HMI server starts, the memory tag will have the same value it had prior to the system shutting down.

Organizing HMI tags Organizing tags makes it easier to work with them, especially if the database is large. To organize tags: „

establish naming conventions. Naming conventions makes wildcard characters more effective when searching for and displaying tags during development and run time.

use folders to group related tags.

Naming HMI tags Tag names can be up to 255 characters long. For tags in folders, the folder name becomes part of the tag name and the backslash counts as one character. The tag name can contain: „

A to Z (upper and lower case)

„

0 to 9

„

underscore ( _ ) and dash ( – ) Creating HMI tags

Q

9–3

The tag name can be mixed case. Tag names preserve upper and lower case for readability but are not case sensitive. For example, the tag name MixerValve1 is the same as mixervalve1. In an expression, tag names that start with a number or contain a dash must be enclosed in brackets, for example, {N33-0}. Also use brackets with wildcard characters to represent multiple tags in an expression, for example, {alarm*}. For more information about using tags in expressions see Chapter 20, Creating expressions.

Using folders to group HMI tags To organize tags, create a folder, and then include tags that are related to one another. To separate the folder name from the rest of the tag name, use a backslash (\). For example, tags in the folder called Pump would start with Pump\. For greater organization, you can nest folders. For example, if a plant is divided into zones, you can organize the tag database first by zone, then by machines in the zone, and finally by devices in each machine. The result might be Area1\Machine1\Pump. IMPORTANT

For optimum performance, do not place all HMI tags in the root folder. It is also recommended that you limit the number of tags in a folder to less than 2000. HMI tags contained in nested folders do not contribute to the total number of tags in the root folder.

For details about creating, duplicating and deleting folders, see Help.

RSView Supervisory Edition User’s Guide

Using the folder hierarchy The hierarchy and spreadsheet work together. The hierarchy shows the tag folders, and the spreadsheet shows the tags within the folders. A folder icon called root is always present in the hierarchy window, at the top of the folder hierarchy. This folder contains all the tag folders you and RSView create. You can nest folders. If a folder icon has a plus ( + ) sign on it, the folder contains one or more folders. If the folder’s icon is blank, it does not contain any other folders. When you nest folders, remember that the backslash in a folder name counts as one character in the tag name.

About derived tags A derived tag is a tag whose value is the result of an expression. An expression can be simply a tag name, or it can be an equation made up of tag names, mathematical and logical operations, special functions, and If-Then-Else logic. Derived tag calculations are performed on the HMI server. A derived tags component is a file that contains the definitions of one or more derived tags. A derived tags component can be run when an HMI server starts, or it can be run using the DerivedOn command, after the HMI server has started. Writing to tags whose value is the result of a derived tag expression is not recommended because a derived tag is evaluated when the tags in the expression change. For example, if the derived tag called Tag3 has the expression of Tag1+Tag2, and if you set Tag3=0, the value of Tag3 becomes zero, and will also be updated when the value of Tag1 or Tag2 changes. Creating derived tags

n

10–1

How to use derived tags Here’s an example of how a derived tag can be used. Suppose there are five weight sensors on a conveyor belt. The tag database contains one tag for each sensor, so the weight at each point on the conveyor belt is monitored. If the weight at any point is excessive, RSView® triggers an alarm. However, if no individual sensor detects an excessive weight, but the total of all five sensors is too high, an alarm might be triggered. To handle this case, you could set up a derived tag to sum the weights of all five sensors. Then, if this total, which would be the value of the derived tag, is too high, RSView can trigger an alarm.

How to use multiple derived tag components You can create multiple derived tag components. At runtime, up to 20 derived tag components, containing a maximum of 1,000 tags, can run simultaneously. Use multiple derived tag components to group derived tags that need to be evaluated at different rates.

Setting up derived tags The steps for setting up derived tags are: 1.

Create the derived tags in the Derived Tags editor.

2.

Set the maximum update rate for the derived tags component in the Derived Tag Setup dialog box.

3.

Save the derived tags component and give it a name.

Using the Derived Tags editor Use the Derived Tags editor in RSView Studio™ to create derived tags. 10–2

Q

RSView Supervisory Edition User’s Guide

To open the Derived Tags editor: 1.

In the Application Explorer, open the Logic and Control folder.

2.

Right-click the Derived Tags editor and then click New, or drag the Derived Tags editor from the Application explorer to the workspace.

IMPORTANT

Do not create derived tags that depend on the results of other derived tags. Derived tag processing is not sequential, and therefore, the results of an expression which includes other derived tags might not occur in the desired scan or order of evaluation. It is best to put as much logic in an expression as possible.

Creating derived tags

Q

10–3

Using the Check Syntax button After you create an expression for a derived tag, use the Check Syntax button to verify that the syntax is correct. You can check the syntax of an expression at any time while the Derived Tags editor is open. If the syntax is invalid, an error appears next to the Check Syntax button. The syntax of the expression is also checked automatically when you click the Accept or Discard buttons.

Using the Accept and Discard buttons When you enter information in the editor, the Prev and Next buttons change to Accept and Discard. Click Accept to save information. Click Discard to discard information that you just entered.

Creating a derived tags component You can use any tag to store the result of a derived tag calculation. The tag must already exist, for example, as an HMI tag (i. e., memory or device) or in a data server, before you can use it as a derived tag. To create a derived tags component

9.

Specify the name of the derived tags component and then click OK.

About the maximum update rate The maximum update rate is the fastest rate at which the value of any derived tag in the derived tag component can be updated. Expressions containing derived tags are evaluated only when the value of a tag or function in the expression changes. Set a maximum update rate for each derived tag component. The maximum update rate also determines the fastest rate at which data servers can send changes in tag values. Set the update rate as fast as, or faster than, the rate at which the values of tags used in the expressions change, unless it is desirable to miss changes in tag values.

Starting and stopping derived tag processing There are many ways to start and stop derived tag processing. Choose the way that works best for the individual application. For distributed applications it is best to start derived tag processing using a server component such as the startup macro, or using even processing. Having clients start and stop derived tags is not advised as one client could stop processing that another client still requires. Creating derived tags

Creating alarms

Q

11–3

Key concepts An alarm occurs when something goes wrong. It can signal that a device or process has ceased operating within acceptable, predefined limits or it can indicate breakdown, wear, or a process malfunction. Set up a system of alarms in the Tags editor by linking alarms to tags you want monitored. When the tag values are updated, they are compared to the limits assigned when the alarm was set up. If a tag value exceeds a specified limit, an alarm of a preset severity is triggered.

Alarms for analog HMI tags An analog tag can trigger a number of alarms when it crosses various threshold levels (unlike a digital tag, which is either on or off).

Thresholds

When defining an analog tag, you can assign up to eight alarm thresholds with different levels of alarm severity to indicate the alarm’s importance. The lowest threshold is one and the highest is eight. You do not have to use all eight thresholds for a tag, but the ones you use must be set up in ascending order. For example, you can assign thresholds one, two, and eight as long as you assign them in that order. Thresholds can be increasing—monitoring for a rising value that crosses the threshold, or decreasing—monitoring for a falling value that crosses the threshold. The following illustration shows a tag with both increasing and decreasing thresholds. The following example shows the changing values of a tag monitoring a motor’s revolutions per minute (rpm). With the threshold settings illustrated, the motor must run between 2,000 rpm and 3,000 rpm, or an alarm is triggered. In the illustration, an X shows when the tag goes into alarm and an O shows when the tag goes out of alarm. 11–4

Creating alarms

Q

11–5

You can specify whether or not alarms will be generated when an analog tag value is moving back to normal operating range and recrosses the alarm trigger threshold. If alarms are to be generated when the motor is moving back towards normal operating range, an alarm will be triggered when the motor speed falls below 5,000 rpm and 4,000 rpm, and when it rises above 1 rpm and 1,000 rpm. If these alarm are not to be generated, make sure the check box ‘Generate alarms when approaching normal operating range’ is cleared.

Variable thresholds

Threshold values can be constant or variable. The previous example uses constant thresholds. To define a variable threshold, specify a tag name in the Threshold box when setting up the thresholds for an analog alarm tag. As the value of the specified tag changes, the threshold changes. Variable thresholds require more system resources than constant thresholds because of the continuous scanning of threshold values and to the processing necessary to detect alarm faults. Alarm faults

A variable threshold must not become higher than the threshold above it or lower than the threshold below it. If this happens, an alarm fault is generated for the monitored tag. To correct an alarm fault, change the variable threshold so it does not overlap either of its neighbors. This can be complex when the neighboring thresholds are also variable, because these boundaries are determined dynamically at run time. When an alarm fault is generated, the following actions occur: „

„

11–6

Q

The tag’s alarm status stays as it was before the fault was generated. An alarm fault is reported to all alarm reporting devices you have set up, such as the alarm log file and the printer.

RSView Supervisory Edition User’s Guide

„

„

The alarm fault status bit for the tag is set in the value table. This notifies other applications that an alarm fault has been generated. The Alarm Type column in the alarm summary states that the tag is in ‘Alarm Fault’.

When the faulty thresholds return to their normal operating range, the alarm fault condition is cleared, the out-of-alarm-fault status is generated and logged, and alarms for the tag resume normal operation. Deadband

With some measured values, such as line pressure, tag values can fluctuate rapidly above and below a critical threshold. Where such conditions exist, you can create a deadband as a buffer to prevent the fluctuations from triggering unnecessary alarms. If the threshold is increasing—monitoring rising values—the deadband range lies below the threshold. If the threshold is decreasing—monitoring falling values—the deadband lies above it. The following illustration shows an increasing threshold of 4,000 rpm with a deadband value of 500 rpm. rpm

Q

11–7

In the above example, the rpm has to fall to 3,500, and then rise above 4,000 rpm before it will trigger the alarm again. IMPORTANT

Use the deadband carefully in safety-critical applications. In the example, the variable has to fluctuate by more than 500 rpm before an alarm is triggered again.

A deadband range may be absolute, as illustrated, or it may be a percentage of the minimum/maximum range for a tag. If the deadband in the illustration were two percent, its range would be two percent of 5,000 rpm, or 100 rpm. If a buffer is not required, the deadband must be set up as zero. With a deadband of zero, alarms will be triggered as soon as the tag value crosses any of its thresholds.

Alarms for digital HMI tags Digital tags are either on or off. Therefore, alarms for digital tags do not have thresholds. They have alarm states. This alarm state

Alarm severity Alarms can range in severity from one to eight to indicate different levels of importance. One is most severe, eight is least severe. For example, a level-four alarm might warn that a vat is half full of liquid, while a level-one alarm indicates that the vat is about to overflow. Both alarms monitor the same tag but have different severity levels. When you set up alarm severity, you specify what severity levels mean and what actions they will trigger. Severity determines the order in which alarms are displayed in an alarm banner.

Alarm messages Alarm messages report information about alarms. There are three types of messages: „

In Alarm message: generated when a tag goes into alarm.

„

Out of Alarm message: generated when a tag goes out of alarm.

Acknowledged message: generated when an operator acknowledges an alarm.

For each message, you can use the default message or create a custom message, and route the messages to a log file, printer, or both.

Alarm log file The alarm log file records alarm incidents that occur. You can set up how often, if ever, you want log files created and deleted, and view the alarm log file using the Alarm Log Viewer. Using the Alarm Log Setup tool alarming to log automatically to an ODBC database. You can also use the AlarmLogSendToODBC command to export the alarm log file to an ODBC database while online. For more information about the AlarmLogSendToODBC command, see Help. Creating alarms

Q

If you export alarm log data to an external, ODBC-compliant database, you can use third-party applications to view the records in the database. The application must be ODBC compliant, for example, you can use Microsoft® Excel, or Microsoft Visual Basic®.

Alarm displays Alarm information can be displayed in: „

the alarm log viewer.

„

graphic displays using graphic objects such as the alarm summary.

When alarms are generated, they are recorded in two places: the alarm log file, and on the HMI server computer where the alarms are generated. The alarm log viewer displays the records in the alarm log file. The alarm summary displays the records in the computer’s memory. Alarm log viewer

The alarm log viewer displays the contents of the alarm log file. The contents of this file depend on the severities set up in the Alarm Setup editor. By default, the log file will have a record for each of the following alarm incidents: „

when a tag goes into alarm

„

when a tag goes out of alarm

„

when an alarm is acknowledged

„

when a tag with an alarm is suppressed

„

when an alarm fault is generated

Set up an application so only essential alarm information is logged. Alarm logging uses system resources and can slow overall system performance. 11–10

Q

RSView Supervisory Edition User’s Guide

Alarm summary

The alarm summary ia a graphic object that displays the alarm information recorded in the computer’s memory. Use the alarm summary to determine which alarm information is displayed and how it is displayed. The alarm summary can display alarms from more than one HMI server. Each HMI server maintains a list of up to 2,000 alarms. As new alarms occur, they appear at the top of the list. When the list of alarms at the HMI server is full and a new alarm is generated, the alarm at the bottom of the list (the oldest alarm) is acknowledged automatically by the system, and then dropped from the the list. Alarms that are acknowledged automatically by the system appear in the alarm log file with SysAk (system-acknowledged) in the TransType (transaction type) field. Alarms are also dropped when they are out of alarm, or acknowledged manually. When alarms are dropped, they are removed from memory. When the AlarmOff command is issued, the contents of the alarm summary are erased. AlarmOff is just one of the RSView commands used with alarms. For details about this command and others, see Help. In the alarm summary, each alarm incident can be set up to be a different color. For example, a low-severity alarms could be set up as blue, medium-severity as yellow, and high-severity as red. When the alarm is displayed, operators can tell its severity at a glance. Use the Graphic Displays editor to create an alarm summary. Graphic objects and displays

You can customize graphic displays to show specific information about alarms. RSView makes all alarm status information available to graphic displays through a set of system tags (see page 11-12). Use these tags Creating alarms

Q

11–11

with numeric and string display objects. Attach visibility and color animation to affect the appearance of the objects. The Alarm Information graphic library contains graphic objects you can drag and drop into a display. For example, to include an alarm banner in a display, drag and drop the banner from the Alarm Information graphic library. Use the graphic objects as they are, or edit them to suit the application’s needs. Alarm system tags

System tags are created and updated by RSView. You can use these tags anywhere a tag name is required. The system tags for alarms are: This tag

Type

Alarm acknowledgment If an alarm appears in the alarm summary or some other alarm display, an operator can acknowledge the alarm. Acknowledging an alarm does not correct the condition causing the alarm, but indicates that an operator is aware of the alarm. A tag, not an alarm, is acknowledged. A single tag might have caused several alarms. For example, a tag representing temperature might have triggered Warm, Hot, and Overheat alarms by the time it is acknowledged. The tag could also have gone in and out of alarm several times before being acknowledged. One acknowledgment is all that is required for all previous and current alarms for a tag, so alarm log files often show fewer acknowledgments than alarms. To acknowledge alarms, operators can: „

„

„

click the Acknowledge or Acknowledge All button in the alarm summary. use the RSView Acknowledge command by itself, or with parameters to name a tag or group of tags. use the RSView AcknowledgeAll command.

Unless an alarm is acknowledged, it remains outstanding until the system is shut down, the alarm summary is full, or alarm monitoring is turned off. Creating alarms

Q

11–13

Alarm suppression You can suppress alarm monitoring for tags. This is useful for testing or for performing repairs or maintenance on a piece of equipment. To suppress alarm monitoring for tags, use the RSView SuppressOn command. To view a list of the tags not being monitored, use the Suppressed List. You can also turn monitoring back on from this list.

Alarm functions in expressions When a tag goes into alarm, or an alarm event occurs, certain information about the alarm is recorded in the value table together with the value of the tag or alarm event. Using expressions, information about alarms can be retrieved on a tag-by-tag basis. For information about alarm events, see page 11-17. IMPORTANT

If a graphic display requires more than 20 alarm functions, for performance reasons it is better to use these alarm functions in derived tags instead.

For example, if the system detects that a tag is in alarm, it sets an internal alarm bit, and then resets the bit when the tag is out of alarm. The following expression checks if a tag is in alarm: ALM_IN_ALARM (tag) where tag is the name of the tag you want to check for alarms. When a tag is in alarm, the expression result is 1. When a tag is out of alarm, the expression result is 0. One way to use this expression is to animate the visibility of a graphic object in a display. When the tag goes into alarm, the ALM_IN_ALARM expression is set to 1, making the object visible. This is an effective way to draw the operator’s attention to the alarm. 11–14

Q

RSView Supervisory Edition User’s Guide

The following expression checks if an alarm has ever been acknowledged: ALM_ACK (tag) The expression ALM_ACK returns 1 if an alarm has been acknowledged. If a tag goes out of alarm without being acknowledged, the expression returns 0. When alarm monitoring starts and a tag has never been in alarm, the ALM_ACK expression returns 1 by default. To reverse this default behavior, create the registry key Alarm Initially Acked on the computer running the HMI server. Once you have created the key, change its string value to False. The key is located at: HKEY_LOCAL_MACHINE\Software\Rockwell Software\ RSView Enterprise\Alarm Server To create or change the key, use the Windows® Regedit32 utility. For details about using Regedit32, click Help in the Registry editor window. ALM_ALLACKED (tag*) The expression ALM_ALLACKED (tag*) returns 1 if all tags that match the pattern have been acknowledged. If any of the tags have not been acknowledged, the expression returns 0. Other functions are also used with expressions to monitor alarms. For more information, see Chapter 20, Creating expressions. Using wildcard characters in alarm expressions

For built-in alarm functions, you can use wildcard characters in the expression to retrieve information about multiple tags at once. This wildcard character

Does this

?

Matches any single character.

*

Matches any number of characters, including the backslash (\) character.

Creating alarms

Q

11–15

For example, the following expression checks if any of a group of tags is in alarm: ALM_IN_ALARM (alarm*) where alarm* represents all tags whose names begin with ‘alarm.’ If one or more of these tags are in alarm, the expression result is 1. If all of the tags are out of alarm, the expression result is 0. Using wildcard characters in alarm expressions may affect performance if the pattern matches a large number of tags. For a list of the alarm functions, see “Tag functions” on page 20-14.

Acknowledge bit An acknowledge bit is a digital tag that can be used for two things: „

to acknowledge an alarm, or

„

to monitor the acknowledged state of an alarm

When you set up an acknowledge bit for a tag, the HMI server monitors the value of the acknowledge bit, and automatically acknowledges the alarm when the value of the acknowledge bit changes from 0 to 1. This is called a remote acknowledge, and a RmAck (Remote Acknowledge) transaction is logged to the alarm log file. When an operator acknowledges an alarm, the acknowledge bit is set to 1. If the Auto Reset feature is enabled, the HMI server resets the acknowledge bit to 0 when the tag goes back into alarm. IMPORTANT

Because an HMI server monitors the value of each acknowledge bit tag, using many acknowledge bits can slow the system down considerably. The acknowledge bit must be set up as a digital tag in the tag database.

For details about setting up an acknowledge bit, see Help. 11–16

Q

RSView Supervisory Edition User’s Guide

Handshake bit A handshake bit is a digital tag that can be used to monitor the status of an alarm. When you set up a handshake bit for a tag, the HMI server sets the handshake bit to 1 when the tag goes into alarm. If the Auto Reset feature is enabled, the HMI server sets the handshake bit to 0 when the tag goes out of alarm. IMPORTANT

The handshake bit must be set up as a digital tag in the tag database.

For details about setting up a handshake bit, see Help.

Switching handshaking on By default, handshaking is off. To switch handshaking on, do one of the following: „

Use the /H parameter with the AlarmOn command.

„

Use the HandshakeOn command.

For information about commands, see Appendix A, RSView commands, or Help.

Alarm events You can customize and extend the RSView alarm monitoring system by writing alarm-detection algorithms using PLC ladder logic, custom programs, or any other appropriate tools. You can then add alarm events to the RSView alarm subsystem, to respond to the alarmdetection algorithms for annunciation, logging, printing, and for display in alarm summaries. By using a tag name for an alarm event, you can customize the alarm features of the tag. For example, you can use alarm events to specify an Creating alarms

Q

11–17

alarm’s time stamp. Because alarms are scanned in the background, alarms that are generated rapidly might appear out of sequence in RSView, because they might all be scanned at the same time, and therefore given the same time stamp. If the sequence in which alarms are generated is important, you might want to record accurate time stamps for the alarms by buffering the alarms in the PLC, and then using alarm events to record them with accurate time stamps in RSView. You can also use alarm events to provide a tag with more than eight thresholds. To create an alarm event, use the AlarmEvent command.

How event-based alarms work

Alarm events let you create alarms without setting up tags in the tag database. Event-based alarms work just like tag-based alarms. They appear in alarm summaries, they can be used with alarm system tags, and they can be logged to disk or printer. You can filter event-based alarms the same way you filter tag-based alarms in alarm summaries. You can acknowledge event-based alarms, either individually, or with wildcard characters, using the Acknowledge command. You cannot suppress event-based alarms. As with tag-based alarms, you can use alarm events with alarm functions in expressions. You can time-stamp event-based alarms with the current time, or by specifying a date and time either in RSView or in alarm-detection algorithms you create for the application. Alarm events are not processed until the AlarmOn command is issued, and alarm events are no longer processed after the AlarmOff command is issued. 11–18

Q

RSView Supervisory Edition User’s Guide

Differences between event-based and tag-based alarms „

„

„

„

„

You cannot specify thresholds for analog alarm events. All analog alarm events have a value of zero. You cannot specify alarm labels for event-based alarms. That is, you cannot use the IntoAlarm and OutOfAlarm labels for digital tagbased alarms, or the threshold labels for analog tag-based alarms. Alarm events have no acknowledge and handshake bits. The Identify feature is not available to event-based alarms, to run a command, macro, or custom program. Event-based alarms are not retained after the AlarmOff command is issued, or after the HMI server shuts down.

Naming alarm events

A name must be associated with each alarm event. The event name can be a tag defined in the tag database as long as the tag does not have an alarm defined for it. Alarm event names can be up to 255 characters long. The alarm event name can contain the following characters: „

A to Z

„

0 to 9

„

underscore ( _ ) and dash (–)

The alarm event name can be mixed case. Alarm event names preserve upper and lower case for readability but are not case sensitive. For example, the alarm event name HopperOverflow is the same as hopperoverflow. When an alarm event name starts with a number or contains a dash, enclose the name in brackets { } when you use it in an expression, for example, {N33-0}. Also use brackets when using wildcard characters Creating alarms

Q

11–19

to represent multiple alarm events in an expression, for example, {alarm*}. Using event types

Use the AlarmEvent command to create into-alarm and out-of-alarm events. Multiple into-alarm events can be processed for the same event name before an out-of-alarm event is received. Use the InAndOutOfAlarm event type for change-of-state alarms. An out-ofalarm event is ignored if no into-alarm events preceded it. How event-based alarms are logged

Event-based alarms appear in the alarm log file in the order in which the alarm transactions were logged. If you specify a time stamp for alarm events, alarm transactions could appear out of order in the alarm log. For detailed information about the AlarmEvent command, see Help.

Setting up general alarm behavior In the Alarm Setup editor you specify the general features of all alarms for a specific HMI server. The editor has these three tabs: Setup - specify general behavior for alarm monitoring and annunciation. Severities - set up logging and alarm behavior for individual severities.

threshold value, or falls below the threshold value. You can enable or disable this feature. For more information about how this feature works, see “Thresholds” on page 11-4. Specifying how often the system checks for alarms

The system does not check for alarms more frequently than the maximum update rate specified in the Alarm Setup dialog box. You should match the maximum update rate to the rate at which you expect tag values to change. For example, if you are monitoring temperatures that fluctuate slowly, you can check for alarms less frequently than if you are monitoring rapidly-changing manufacturing processes. Setting up alarm monitoring on redundant servers

If you have set up redundant HMI servers, alarms can be logged and printed on the active HMI server only, or on both the active and the standby HMI server. IMPORTANT

11–22

Q

For alarm states to be synchronized properly, the clocks on the primary and secondary HMI servers must be kept synchronized to a time server. If the clocks on both computers are not synchronized, when fail-over occurs multiple alarms or inconsistent information might be displayed in an alarm summary.

whether to log alarm data to a central, ODBC-compliant database. This step is optional.

„

IMPORTANT

You must run the Alarm Log Setup program on the same computer as the HMI server that is monitoring tags for alarms. If you run the Alarm Log Setup program on a computer that does not contain an HMI server set up to monitor tags for alarms, the settings will have no effect. The alarm log files generated on one computer do not contain data for RSView SE servers running on other computers. You must set up alarm log files separately for each computer on which RSView SE servers are running. If there is more than one HMI server on a single computer, the alarm log file will contain entries from both HMI servers.

To open the Alarm Log Setup program X

In RSView Studio or the RSView Administration Console, click Tools on the bar menu and then click Alarm Log Setup. You can also open the Alarm Log Setup editor by clicking the Start button, selecting Programs, Rockwell Software, RSView Enterprise, Tools, and then clicking SE Alarm Log Setup.

For details about using the Alarm Log Setup program, see Help.

Specifying when log files are created Use the Logging tab in the Alarm Log Setup editor to specify when log files are created. You can set up an application to create new log files periodically, or you can prevent new files from being created. In each 24-hour period, up to 26 new files can be created. If you attempt to create a 27th file, RSView continues logging data to the 26th Creating alarms

Monitoring disk space

If the computer’s hard disk is full, alarm logging stops and no more log files are created. For information about monitoring disk space on computers running HMI servers, see page 28-4.

Specifying when log files are deleted Use the File Management tab in the Alarm Log Setup editor to specify when log files will be deleted. You can delete log files after a specified period or once a specified number of files have been created. If you 11–30

Q

RSView Supervisory Edition User’s Guide

never want files deleted, leave the check boxes under Delete Oldest Files blank. Alarm log files are deleted only when a new file is created. If the application creates a new file each day and deletes the oldest file every third day, the project will have files for the three previous days’ data, as well as a file for the current day. If you have set up File Management to delete the oldest files when a new one is started, and you are exporting data to an ODBC database, make sure you export the data before the oldest file is deleted.

Setting up logging to a central database Use the Central Logging tab in the Alarm Log Setup editor, to set up logging to a central, ODBC-compliant database. Central logging works by periodically exporting the contents of the alarm log file to an ODBC-compliant database. RSView supports the following ODBC-compliant databases: Sybase SQL Server, Oracle, and Microsoft SQL Server. If you have set up file management to delete the oldest files when a new set is started, and you are exporting data to an ODBC database, make sure you export the data before the oldest files are deleted. For details about setting up logging to a central database, see Help.

Exporting alarm log files manually to ODBC format Using the command, AlarmLogSendToODBC, you can export logged activities manually from the alarm log file to an ODBC-compliant database. If the table in the database to which you are attempting to export data is not ODBC compliant, the export will fail. If an ODBC-compliant table does not exist, RSView will try to create it. Creating alarms

Q

11–31

When you export data to an ODBC table, RSView keeps track of the exported data in a control file called Alarm.exp. This file is located in the log path where the .dat files are stored. The next time you export data, only the newest data is exported. If the control file is deleted, all the alarm log data in the .dat files are exported when you issue the export command. If you have set up file management to delete the oldest files when a new set is started, and you are exporting data to an ODBC-compliant database, make sure you export the data before the oldest files are deleted.

Example: Exporting alarm log files to ODBC format on demand To export the contents of the alarm log files to an ODBC-compliant database on demand, create a button in a graphic display. The button’s press action should be the AlarmLogSendToODBC command. When the operator presses the button, the contents of the alarm log file are exported to the ODBC database. The AlarmLogSendToODBC command exports only the records added to the alarm log files since the last export. For information about the contents of the alarm log ODBC tables, see page C-2.

Adding remarks to the alarm log file at run time Using the AlarmLogRemark command, you can add information to the alarm log file at run time. Parameters for the command let you add a text comment, the alarm severity, and the tag name to the alarm log file Other parameters let you prompt the operator for the text part of the remark at run time, and log the remark to a printer as well as to the alarm log file. 11–32

Q

RSView Supervisory Edition User’s Guide

You cannot display alarm log remarks in alarm summaries.. Using the /P parameter with the AlarmLogRemark command, you can prompt the operator at run time to type a remark for the alarm log file.

At run time, only one Alarm Log Remark dialog box is displayed at a time, and the operator must respond to the dialog box before the next one is displayed. Alarm logging must be on before you can use the AlarmLogRemark command. To start alarm logging, issue the AlarmLogOn command. For details about the AlarmLogRemark command, see Help.

Suppressing alarm printing To suppress alarm printing for all tags, use the AlarmPrintOff command. To re-enable printing of alarms, use the AlarmPrintOn command. Using AlarmOn and AlarmPrintOff in the correct order

AlarmOn normally logs alarms to both the alarm log file and the printer. However, the order in which you issue the AlarmOn and AlarmPrintOff commands affects what happens at run time. „

„

If you issue the AlarmOn command before you issue the AlarmPrintOff command, alarm monitoring starts. Alarms are logged to the alarm log file and the printer until you issue the AlarmPrintOff command. If you issue the AlarmPrintOff command and then issue the AlarmOn command, alarms are logged to the alarm log file, but not to the printer. Creating alarms

Q

11–33

The AlarmPrintOff and AlarmPrintOn commands are not retained across RSView sessions. If you issue the AlarmPrintOff command before AlarmOn, alarms will not print to the printer. But if you shut down RSView, restart it, and then issue the AlarmOn command, alarms will be logged to alarm log file and the printer until you issue the AlarmPrintOff command.

Suppressing alarm logging You can suppress alarm monitoring for tags. This is useful for testing or performing repairs or maintenance on equipment. To suppress alarm monitoring for tags, use the SuppressOn command. To suppress all alarms for the specified tags, issue the SuppressOn command before the AlarmOn command. For more information about RSView commands, see Help.

Using the Suppressed List Use the Suppressed List to see which tags are not being monitored for alarms and to turn alarm monitoring back on.

To turn off suppression for a tag, click the tag name, and then click Suppress Off.

Viewing alarm log files The Alarm Log Viewer displays the contents of alarm log files. The contents of the alarm log files depend on how you set up alarm severities in the Alarm Setup editor. For information about the contents of the alarm log ODBC tables, see page C-2. You can display alarm log files stored either on the local computer or on a remote computer, and you can select the number of log files to be displayed in the alarm log viewer. Each alarm log file is displayed in a separate tab in the alarm log viewer. To open the alarm log viewer X

For details about a programmatic workaround, see technical note P9029 in the Rockwell Software Support Library.

About alarm log files Alarm information is stored in file sets, in proprietary format. How log files are named

When a log file is created, it is named automatically. The name is based on the date the file was created and the type of data it contains. The format for the name is YYYYMMDDnz.dat, where: „

YYYY are the four digits of the year.

„

MM is the month.

„

DD is the day.

„

11–36

Q

n is the sequence letter (‘a’, ‘b’, ‘c’, and so on). This letter indicates the sequence in which the files were created. You can have up to

RSView Supervisory Edition User’s Guide

26 files (‘a’ to ‘z’) per day. At midnight, the sequence starts at ‘a’ again. „

z is the file type: ‘l’ (lowercase L) is for alarm.

If you are using short file names, or if the path where the log files are stored does not support long file names, the format for the name is YYMMDDnz.dat, where YY are the last two digits of the year.

Example: Log file name The log file named 20041015bl.dat was created in the year 2004, month 10, and day 15. The ‘b’ indicates that this is the second file created that day. The ‘l’ (lowercase L) indicates that this is an alarm log file.

Setting up security to log alarms remotely If you are logging to a network drive, network share, or ODBC database that is not located on the same computer as the HMI server, you must change the Windows security settings of the alarm log program files.

Creating an alarm summary The alarm summary is a table that displays the active alarms recorded in an HMI server. To set up an alarm summary, you decide how many columns you want the table to have, how wide the columns will be, and what information the columns will contain. You can also specify the tags and, in a distributed application, the areas from which you want data displayed. At run time, operators can use the alarm summary to view and interact with the alarms. Creating alarms

Q

11–39

Creating an alarm summary object An alarm summary object can be part of a graphic display or it can fill the entire graphic display. You can use the pre-built alarm summary, called Alarm Information, in the graphics library, or you can create an alarm summary object. For details about creating an alarm summary object, see Help.

The parts of an alarm summary A new alarm summary looks like this: Header area: Use the commands on the Insert menu to insert headings here. Divider: Use the mouse to move the divider up and down. Body area: The area where alarm information is displayed at run time. Button bar: Use the commands on the Format menu to specify which buttons are included and where the bar is located.

Inserting headings The Insert menu contains the items that can appear in the summary. To add a heading for an item, click the item on the Insert menu. You can add as many items as you want and place them in any order you want. An alarm summary can include an operator’s name. When a tag goes into alarm, Operator Name column shows the name of the Windows 11–40

Using Sort

Use Sort to specify the order in which alarm information is displayed. You can sort filtered or unfiltered data. You cannot sort by area name in stand-alone applications. Filtering and sorting at run time

Alarm information can also be filtered and sorted at run time, but changes are not saved. Displaying tag names with the areas they belong to

To display tag names with the names of the areas they belong to, click Display full tag name. This option is not available for stand-alone applications.

Examples: Using area and tag names in filters To collect all alarm transactions from the area called Powertrain, type: /Powertrain::* To collect alarm transactions from the current area for the tag name Coolant_East, type: Coolant_East To collect alarm transactions from the current area for all tags whose names begin with Coolant, type: Coolant* To collect all alarm transactions for the current area, type: * 11–44

Q

RSView Supervisory Edition User’s Guide

To collect alarms from specific areas for tag names that match a pattern, you can type: /Powertrain::Coolant* /Press::FlowValve* To collect alarms from more than one HMI server, you can type: /Powertrain::* /Press::* You can also use the Areas and Tags buttons to browse for area or tag names rather than typing them.

Tag placeholders

You can also use tag placeholders to specify the area or tag names you want to appear in the alarm summary. A tag placeholder is the cross-hatch character (#) followed by a number from 1 to 500. The placeholder can also contain wildcard characters and folder names. For more information, see “Using tag placeholders” on page 16-31.

Examples: Using tag placeholders with area names To display alarm transactions from an area whose name you want to specify at run time using a parameter file or on the command line, type one of the following: /#1::* or /Area1/#1/Area3::* To display alarm transactions from a specific area for a tag whose name you want to specify at run time, type: Area::#1 Creating alarms

Q

11–45

To display alarm transactions for all tags in a specific area and folder, type: Area::Folder/#1/* In the example shown above, the placeholder #1 allows you to substitute a folder name at run time. Resolving tag placeholders at run time

If you use tag placeholders, at run time you must specify the tag or folder name each placeholder represents, either by using a parameter file or by specifying the tag or folder names as parameters to the Display command. If you use a parameter file, it can contain wildcard characters.

Example: Using a parameter file to replace tag placeholders The parameter file called Beans specifies which tags to use for the placeholders in a display: #1 = bean_weight #2 = bean_level #3 = bean_temp To run the display called Canning with the Beans parameter file, type: Display Canning /PBeans For more information, see “Replacing tag placeholders using a parameter file” on page 16-32, and “Replacing tag placeholders using parameters with the Display command” on page 16-33.

Sorting data Select Sort from the Data menu to open the Sort dialog box. By default, alarm information is sorted first by date and time, then by severity, then, in distributed applications, by area name, and finally by tag name. 11–46

Q

RSView Supervisory Edition User’s Guide

This means that alarms are presented chronologically. If two or more alarms have the same time and date, these alarms are presented in order of severity. If any alarms have the same time and date and the same severity, they are then presented by tag name. For details about using the Sort dialog box, see Help.

Running commands, macros, or custom programs in response to alarms Using the Execute and Identify buttons in an alarm summary, you can run a command, macro, or custom program to respond to tags’ alarm conditions. Use the Execute button to run a command, macro, or custom program that applies to all alarms in the summary, for example to create a custom alarm report for analyzing plant maintenance efficiency. Use the Identify button to run a command, macro, or custom program that applies only to the tag for the highlighted alarm. The Identify button can run a different command, macro, or custom program for each tag, for example to run a different help file for each tag’s alarm conditions. About the Execute button

With the Execute button, you can specify a command or macro that operators can run with reference to the highlighted alarm in an alarm summary. The Execute command can be appended with tag information derived from the highlighted alarm - for example, the area name, tag name, alarm type, severity, value, date and time, and the tag type. IMPORTANT

In stand-alone applications, you cannot include the area name.

Creating alarms

Q

11–47

Use the execute feature to apply a common command, macro, or custom program to the alarm that is selected in the alarm summary. For example, you can run a custom program to add entries to a custom alarm report for selected alarms in an alarm summary, and you can pass arguments from the highlighted alarm to the custom program. For details about setting up the Execute button, see Help. About the Identify button

With the Identify button, you can specify a command or macro that operators can run when a tag is in alarm. Use this button to provide information about an alarm. For example, use the Display command to open a display that contains instructions about how to handle a motor that is running too fast. For details about setting up the Identify button, see Help.

Using alarm data with commands Use the Execute item on the Data menu to execute a command (whether an RSView command, an RSView macro, or a custom program), and to append parameters to the command. At run time, the parameters are derived from the highlighted alarm in the alarm summary. For example, to log an entry in the FactoryTalk Diagnostics log file with information about a particular entry in the alarm summary, use the Remark command. To include details about the highlighted alarm, for example, the alarm’s severity or the tag’s value, check the corresponding boxes in the list of parameters. Using parameters

Parameters are appended to the command in the same order in which the parameters appear in the dialog box. You can substitute parameters 11–48

Q

RSView Supervisory Edition User’s Guide

into any position within a command by passing the parameters to a macro. For details about using parameters with macros, see page 22-3. Parameters are separated by a space, unless you click Separate Parameters with commas. IMPORTANT

A space is not automatically appended to the end of the command text. If you are using parameters, and require a space between the end of the command, macro, or custom program and the first parameter, be sure to include the space at the end of the command text.

Severity and value are shown only for alarms of type IntoAlarm. For alarm types OutOfAlarm and IntoFault, the severity is 0.

Adding area names to parameters

To include the area name in the parameters passed to the command for the Execute button, select the Insert Area name check box. If you select the Insert Area name check box, the Area name appears automatically between the first and second word you type in the Execute Command Text box. Because you cannot change the position of the area name, be sure the command shown at the bottom of the dialog box is syntactically correct before you click OK. Alternatively, use a macro to substitute the parameters into any position within the command. If you select the Tag name check box, to pass tag names as arguments to the Execute command text, the tag names always include the area name, whether or not areas are displayed in the alarm summary. At run time, the area name is the area of the alarm that is highlighted in the alarm summary. Creating alarms

Q

11–49

Example: Using the AlarmLogRemark command with the Execute button You can use the Execute button to prompt the user at run time to add a remark to the alarm log file. To do this, add the command AlarmLogRemark /P /T to the Execute button in the alarm summary, and then click the Tagname parameter.

At run time, the following happens: „

„

„

11–50

Q

the /P parameter displays a dialog box to prompt the operator for a remark. the /T parameter logs a string in the Tagname column of the alarm log file. the Tagname parameter records the name of the highlighted tag in the alarm summary in the Tagname column of the alarm log file.

RSView Supervisory Edition User’s Guide

You cannot change the order in which parameters are passed to the command line for the alarm summary Execute button. To use the alarm summary Execute button with the AlarmLogRemark command, and have the tag name added correctly to the /T argument, you must ensure that the argument (/T) appears last on the command line. For details about using the AlarmLogRemark command, see “Adding remarks to the alarm log file at run time” on page 11-32, or see Help. Using the Execute button to run a custom program

If you set up the Execute button to run a custom program, and you copy the alarm summary from one application to another application, you must ensure that the custom program is available in the new application, otherwise the Execute button will not run the program.

Viewing the area name in tag names In an alarm summary, you can display tag names with the names of the areas they belong to. To do this, click the Data menu, and then click Display full tag name.

About FactoryTalk Diagnostics FactoryTalk Diagnostics is a FactoryTalk component that performs services similar to the RSView activity logger, which it replaces. It records information about various types of system activity including: „

command and macro usage.

„

operator comments.

„

system messages and errors.

„

errors from the communication network.

„

tag read and write activity.

archived for future processing or analysis. exported to ODBC format while online. This enables analysis of the data in third-party, ODBC-compliant tools such as Microsoft® Excel, and Business Objects Crystal Reports.

Summary of steps These are the steps required to set up FactoryTalk Diagnostics for an application. „

„

Decide from which computers on the network information needs to be logged. On each of the computers on which you want to log system activity, run the FactoryTalk Diagnostics Setup tool. Set up: „

„

„

where the information will be sent. These are called destinations. By default, system activity is logged to a local file on each computer. which categories of information are sent to which destination. This is called message routing, and allows you to specify where (to what destination) to send which information (of what severity) and for whom (for what audience).

To log system activity to a central, ODBC-compliant database, set up the database, and then set up the ODBC Database destination in the FactoryTalk Diagnostics Setup tool.

For details about the schema for the ODBC database, see Appendix C, odbc database schemas.

Key concepts The settings for FactoryTalk Diagnostics apply to all Rockwell Software products installed on a single computer. You must set up FactoryTalk Diagnostics separately on every computer on which you want to log system activity. 12–2

Q

RSView Supervisory Edition User’s Guide

Setting up FactoryTalk Diagnostics involves: „

„

setting up destinations, where logged information is received for storage or display. setting up which destinations receive which specific types of messages. This is called message routing.

Destinations FactoryTalk Diagnostics messages can be sent to various destinations—for example, the message log file on the local computer, an ODBC-compliant database, and the RSView Diagnostics List at the bottom of the window in RSView Studio™, or the RSView SE client. Each destination has features or behavior you can set up. IMPORTANT

The destinations available might vary, depending on which Rockwell Software products are installed. RSView adds the ODBC Database and Diagnostics List destinations to FactoryTalk Diagnostics. If RSView is not installed on the computer, these destinations are not available in FactoryTalk Diagnostics.

Setting up redundancy for log files

You can set up redundancy for Diagnostics log files by logging to an ODBC-compliant database, and setting up a copy of the database on another computer, that will act as a backup if communications to the primary database are interrupted. If you also set up local log files, you can use them to buffer information if communications with the database are lost. By default, all system activity is logged to a local file on each computer. Logging system activity

Q

12–3

Message routing You can decide which destinations receive messages of which severity, and for which audience. This ensures that information is provided to the appropriate person and place.

Example message-routing destinations „

You can route messages that contain information about system activity to the local log file. You can also route warnings about things that might go wrong, to the local log file. This allows a control systems engineer to analyze system activity and performance, and make corrections during scheduled maintenance times.

„

You can route errors that require immediate action to the FactoryTalk Diagnostics List, as well as the log file. At run time, if the FactoryTalk Diagnostics List is visible, an operator can alert the plant’s control systems engineer to problems such as tag errors, as they occur. During scheduled maintenance time, the engineer can use the errors, together with warnings, or information messages recorded in the local log file, to analyze operation of the system, and then make the necessary corrections.

Message categories Messages sent to FactoryTalk Diagnostics are categorized by severity and audience. To route messages, specify that a particular destination (for example, the FactoryTalk Diagnostics List) receives messages of a particular severity (for example, Errors), and audience (for example, Operator). 12–4

Q

RSView Supervisory Edition User’s Guide

Severity

RSView uses four message severities: „

„

„

„

Errors indicate that a process or action has failed. For example, a tag’s value could not be written, or an ActiveX® control is missing. Warnings indicate that a process or action might not function correctly, or might eventually fail if preventive action isn’t taken. For example, if an ActiveX control used in a graphic display is a different version than the one installed at the RSView SE client, a warning is logged to indicate the mismatch. Mismatched ActiveX controls might not behave as expected at run time. Information indicates that a process or action has completed successfully. For example, a user logged on to the system. Audit indicates that the system configuration has been changed. RSView also records an Audit message: „

„

for all tag writes. whenever an editor that handles multiple components adds, deletes, or removes a component. Examples of multicomponent editors are the Data Log Models editor, Graphic Displays editor, and Macros editor.

Audience

RSView uses three message audiences: Operator, Engineer, and Developer. RSView assigns the Operator audience for all messages it generates, except for messages with the Audit severity. Audit messages are assigned the Developer or Engineer audience. Audit messages include tag writes. Logging system activity

Q

12–5

How tag writes are categorized

The severities Audit and Information are assigned to tag writes that are successful. The severities Audit and Error are assigned to tag writes that fail. The audiences for tag writes, whether successful or unsuccessful, are Developer and Secure. All other messages are categorized as Operator with severities of Error, Warning, or Information. The Secure audience allows auditing tools, such as those required for US Government 21 CFR Part 11 compliance, to track system activity. IMPORTANT

You cannot change the audience or the severity categories assigned to diagnostic messages. For example, you cannot specify that a Developer receive all messages of type Error. When you set up message routing for Diagnostics, you specify where the messages for a particular audience and severity will be logged. For example, you can specify that messages about tag writes that are logged for the audience Developer be sent to the local log file, or the Diagnostics List, or both, or neither. If messages for a particular combination of audience and severity are not routed to a destination, they will not be logged.

Setting up FactoryTalk Diagnostics in RSView The information in this chapter applies to setting up FactoryTalk Diagnostics for use with RSView. For details about using the FactoryTalk Diagnostics Setup tool, see the context-sensitive help provided for the tool. 12–6

Q

RSView Supervisory Edition User’s Guide

To open the FactoryTalk Diagnostics Setup tool X

In RSView Studio or in the RSView Administration Console, select Diagnostics Setup from the Tools menu, on the Windows Start menu select Start, Programs, Rockwell Software, Utilities, and then click Diagnostics Setup.l.

IMPORTANT

You must run the Diagnostics Setup tool on every computer on which you want to log system activity. System activity for all the Rockwell Software programs running on the computer is logged to the log files on that computer.

Logging to a central database In addition to logging to a local log file on each computer, you can also set up FactoryTalk Diagnostics to log data to a central, ODBCcompliant database. This option is only available if FactoryTalk Directory, RSView Studio, RSView Administration Console, RSView SE Server, or the RSView Logging system activity

Q

12–7

SE Client are also installed on the computer on which FactoryTalk Diagnostics is installed. Central logging works by periodically exporting the contents of the local log file to an ODBC-compliant database. RSView supports the following ODBC-compliant databases: Sybase SQL Server, Oracle, and Microsoft SQL Server. If you have set up FactoryTalk Diagnostics to overwrite events in the local log file, make sure messages are logged to the ODBC-compliant database before the oldest events are deleted. For information about the contents of the FactoryTalk Diagnostics ODBC tables, see page C-1.

Setting up message buffering FactoryTalk Diagnostics messages are stored in the computer’s local log file, and are exported to the ODBC-compliant database at the interval you specify.

12–8

Q

RSView Supervisory Edition User’s Guide

To buffer messages, in the ODBC Destination Setup dialog of the Diagnostics Setup tool, specify how long messages will remain in the local log file after they have been exported to the ODBC-compliant database. This is useful in the event of a network failure, or any other reason that causes the database to be unavailable. In this case, the messages remain in the local log file until the buffer time expires. If the ODBC-compliant database becomes available during that time, the buffered messages are then exported to the database.

Setting up message routing For each destination you have set up, you can specify which messages will be routed to it. Messages are categorized by audience and severity. See page 12-4 for details.

IMPORTANT

All messages are logged as Error, Warning, or Info, with the audience, Operator, except for tag writes which are logged as Audit, with the audiences Developer or Engineer, and Secure.

If the operator is unaware of this, and presses the button again, another instance of the viewer is opened. This could result in multiple Diagnostic viewers being opened. To avoid this, the viewer can be brought to the front manually and closed it when it is no longer required, or you can work around this problem programmatically. For details about a programmatic workaround, see technical note P9029 in the Rockwell Software Support Library.

About data logging Data log is an RSView® component that collects and stores tag values. You specify which tag values to collect, when to collect them, and where to store them by defining a data log model. Logged data can be stored in an internal file set, or an ODBCcompliant (Open Database Connectivity) database, and can be: „

displayed in trends.

„

archived for future use.

„

analyzed using any ODBC-compatible reporting software, such as Microsoft® Excel, or Seagate Crystal Reports.™ Using data logging

n

13–1

About data log models A data log model defines which tags to log data for, when to log the data, and where to log the data. In the model you also specify the format of the log files (file set, or ODBC) and when to create and delete the files, or records. A data log model can contain up to 10,000 tags.

Using multiple data log models At run time, up to 20 models can run simultaneously on each RSView SE server. Use multiple data log models to: „

store related information in separate file sets.

„

log groups of tags at different rates.

„

log groups of tags based on events.

About data log storage formats Logged data is stored in either an internal file set or in an ODBCcompliant database. File sets store tag values in proprietary-format files. You cannot view the contents of these file sets, except in trends. File sets provide faster performance for historical trends than an ODBC database. If you log tag values to an ODBC database, you can view the data in trends, or use third-party, ODBC-compliant tools to analyze and create reports from the data. If the ODBC database becomes inaccessible, RSView logs the data to backup files in proprietary format. To use data in multiple formats, define multiple data log models for the same tags. 13–2

Q

RSView Supervisory Edition User’s Guide

Log file sets Data log files are stored in sets of three. Each file set includes a file for storing numeric values (either integers or floating point values), text, and tag names. How log file sets are named

When a log file set is created, it is named automatically. The name is based on the date the file was created and the type of data it contains. RSView names the log file sets using long file names. The maximum length of a log file set’s name, including its path, is 200 characters. File sets are named using the following format for the file name: YYYY MM DD NNNN <(type)>.dat „

YYYY is the year.

„

MM is the month.

„

DD is the day.

„

„

„

NNNN is the sequential file identifier. This number indicates the sequence files were created in. You can have up to 9999 file sets per day. At midnight, the sequence starts at 0000 again. is a text string you can specify to help identify the log file. The maximum string length is 20 characters. <(type)> is the file type. The type is enclosed in parentheses. There are three file types: Tagname, Float (for analog and digital tag values), and String.

Example: Long file name The log file named 2003 10 30 0004 Oven Temperatures (Float).dat was created October 30 2003. The 0004 indicates that this is the fourth file set created that day. Oven Temperatures is the log file identifier Using data logging

Q

13–3

string, which the user defined to help identify the data. (Float) indicates that this file contains analog or digital tag values.

ODBC database storage format Use the ODBC database storage format to store data in an ODBC data source such as Oracle or Microsoft SQL Server. The ODBC format stores data in up to three tables: „

Tag table (optional)—stores tag names in an index so they can be referenced using a 2- or 4-byte numeric field (rather than a 40-byte character field) in the float and string tables.

„

Float table—stores analog and digital tag values.

„

String table (optional)—stores string tag values.

For details about the contents of the tables, see page C-5. ODBC backup files are stored as binary files with the extension .obf. You cannot view the contents of the .obf files. How ODBC tables are named

The ODBC tables are created with the default names TagTable, FloatTable, and StringTable. In the Data Log Models dialog box, you can edit these names before creating the tables, or you can specify the names of different tables. If you specify a backup path for an ODBC model, RSView names the backup log files as described on page 13-3.

Creating data log models To set up a data log model, in the Data Log Models editor specify:

13–4

Q

„

which log file format to use.

„

where to store data log files (primary or secondary paths).

RSView Supervisory Edition User’s Guide

„

when to create and delete log files.

„

which actions will trigger logging.

„

which tag values will be logged.

Opening the Data Log Models editor To open the Data Log Models editor: 1.

In the Application Explorer, open the Data Log folder and doubleclick the Data Log Models icon or right-click the icon and then click New.

Set up general aspects of the model. Specify the paths to which the data is logged. Specify when log files will be created and deleted.

Specify how and when logging should occur. Specify the tags for which you want to log data.

Specifying the storage format In the Setup tab of the Data Log Models editor you provide a log file identifier string, which becomes part of the file name for the data log files, and select a storage format. You can also type a description of the model. This is for information only. Using data logging

Q

13–5

When you select File Set as the storage format and you plan to log string tags, specify the number of characters to be logged. When you select ODBC database as the storage format, type the path and file name of the ODBC data source, and specify the ODBC tables that will be used, or create new tables. To create tables for a new data source, click Create Tables. If RSView cannot create the tables automatically, you will have to open the database using its editing tool, and create the tables manually. To select an existing table from the specified database, click the Browse button and then select a table in the Select ODBC Table dialog box. To view the order, type, length, and precision of the fields in the table, click the table to select it and then click Details. For more information see, “Working with ODBC data sources” on page 13-9.

Setting up log paths Set up logging paths in the Paths tab of the Data Log Models editor. If the storage format is file sets, specify the primary path, and an optional secondary file path in case the primary path becomes unavailable. If the storage format is ODBC, you can specify a backup file path for the ODBC database. To prevent loss of data, you can set up a secondary or backup logging path. If the disk space for the primary path is full, data logging switches to the secondary path, if set up, until space becomes available on the primary path. If you do not do this, when the primary path runs out of disk space, data logging stops and no more log files are created. For details see Help. 13–6

Q

RSView Supervisory Edition User’s Guide

Setting up and managing data log files In the File Management tab of the Data Log Models editor, you specify when to start new files and when to delete old files. If the data log model uses the ODBC format, data is added continually to the same database, and this section does not apply. If the data log model uses file sets, RSView logs the data to sets of files. You can set up an application to create new file sets: „

periodically.

„

at specified times.

„

when a particular event occurs.

You can also select Never, in which case all data is logged to one file set. Log files are saved in the folder you specify on the Paths tab.

Deleting file sets and ODBC database records

If a data log model uses file sets, you can set up file management to delete file sets after a specified period or once a specified number of file sets has been created. If you never want file sets deleted, clear the check boxes under Delete Oldest Files. Data log file sets are deleted only when a new file set is created. If the application creates a new file set each day and deletes the oldest file set every third day, there will be file sets for the three previous days’ data, as well as a file set for the current day. If a data log model uses the ODBC database format, you can purge old records from the database using standard relational database tools or SQL queries. You can also set up RSView to delete (purge) records in the ODBC database after a specified time. For more information, see Help. Using data logging

Q

13–7

Specifying when to log data In the Log Triggers tab of the Data Log Models editor, you specify what will trigger data to be logged and when or how frequently this will occur. You can set up logging so tag values are logged: „

periodically (periodic logging).

„

only when a tag’s value changes (on-change logging).

„

when a particular event occurs and triggers the DataLogSnapshot command (on-demand logging).

For for more information about the DataLogSnapshot command, see page 13-14. You can combine types of logging. For more information, see “Combining logging” on page 13-15.

Choosing the data to be logged In the Tags in Model tab of the Data Log Models editor, you specify which tags will be scanned for data for the data log model. Log models can contain up to 10,000 tags. For more information, see Help.

Editing the data log model You can edit a model during development or run time, using either RSView Studio™ or the RSView Administration Console. If you change a model at run time, the changes will not take effect until you stop data logging and then restart it. IMPORTANT

13–8

Q

If a tag that you delete from a data log model is used in a trend object, be sure to remove all references to the deleted tag from the trend.

RSView Supervisory Edition User’s Guide

Changing log paths using the RSView Administration Console You can change the log paths after an application has been deployed by using the RSView Administration Console (you don’t need to use RSView Studio). You can change the primary and secondary paths for file sets, and the backup path for ODBC data log models. You cannot change the ODBC database using the Administration Console.

Working with ODBC data sources Using an existing ODBC data source You can log data to an existing ODBC data source, but its tables must contain fields that are formatted for the RSView data log. There are two ways to prepare tables for data logging to an existing database: „

„

set up the RSView data log fields in the existing ODBC tables before setting up a data log model. create new tables automatically or manually in the existing database using the Data Log Models dialog box.

To use the tables in an existing ODBC data source 1.

Add fields for the data log data to the tables in the ODBC database. The section “Data log tables” on page C-5 describes the order and type of fields needed to log data to an ODBC database. Edit the tables as described in the documentation for the ODBC database you are using.

Using data logging

Q

13–9

2.

Set up a data log model, as described in Help. Specify the existing ODBC database as the ODBC Data Source, and then specify the tables you edited.

To create new tables in an existing ODBC data source 1.

Specify the name of the existing ODBC data source in the ODBC Data Source field of the Data Log Models editor. For more information, see Help.

2.

Click Create Tables. RSView automatically creates new data log tables in the existing database. You can also create tables manually.

3.

Set up the rest of the data log model, as described in Help.

Creating a new ODBC data source To create a new ODBC data source, use the ODBC Data Source Administrator in Control Panel. For details about using the ODBC Data Source Administrator, click Help in the ODBC Data Source Administrator window. You can create the tables for the new data source using either method described previously.

Switching log paths at run time RSView lets you specify a secondary or backup path to use if the primary path for file sets or the ODBC database becomes unavailable. This could happen because of network failures, or because of lack of disk space on the computer where the data is being logged. If the primary data log location becomes unavailable, RSView begins to store the data in a buffer. The buffer can hold up to 64 Kb of data. If the primary location is still unavailable when the buffer fills, or when the maximum amount of time to buffer data has elapsed, RSView switches to the secondary path. 13–10

Q

RSView Supervisory Edition User’s Guide

RSView checks periodically to determine whether the primary file path has become available again. If it has become available, RSView switches back automatically. RSView also checks the status of the primary path if the secondary path becomes unavailable, and will switch back if possible. If both paths are unavailable, RSView buffers the data. If the buffer fills and both paths are still unavailable, RSView empties the buffer (the data in the buffer is lost) and begins storing new data in the buffer. RSView continues checking both paths until one becomes available. If the data log file is locked, data is buffered for the time specified for Maximum time to buffer data in the Advanced Configuration dialog box, and then a new set of files is created on the primary path. If the secondary path is not set up, the data is buffered for 10 minutes (the default value for maximum time). If the maximum time is set to 0, a new file is started immediately. If the model is logging to the secondary path and the file is locked, the behavior is the same: the data is buffered, and then a new file is created when the specified time period has elapsed. You can also switch back to the primary path or ODBC database manually, using the DataLogSwitchBack command (see page 13-11) or the DataLogMergeToPrimary command (see page 13-12). You cannot switch manually from the primary path or ODBC database to the secondary or backup path. For models that use the file set format, RSView creates a new file set each time the logging path changes.

Using the DataLogSwitchBack command You can switch back to the primary path manually using the DataLogSwitchBack command with these parameters: or * (asterisk). DataLogSwitchBack (where is a data log model name) switches logging for the specified data log model. DataLogSwitchBack * switches logging for all data log models Using data logging

Q

13–11

that are currently running. You can use this anywhere you can enter an RSView command or macro. The switchback is performed only if the model is running, RSView is logging data to the secondary or backup path, and the primary path or ODBC database is available. For file sets, RSView creates a new set of files when it switches back to the primary path. To enable operators to issue this command at run time, you could create a button object and use the DataLogSwitchBack command as the press action. In order to prevent an adverse effect on performance, data is not moved from the secondary or backup path when you switch back to the primary path or ODBC database. You must move it manually using the DataLogMergeToPrimary command.

Using the DataLogMergeToPrimary command When you begin writing to, or reading from a data log model, RSView sends a message to the FactoryTalk™ Diagnostics log if there are files on the secondary or backup path. You must move data manually from the secondary or backup path to the primary path or ODBC database using the DataLogMergeToPrimary command with these parameters: or * (asterisk). DataLogMergeToPrimary (where is a data log model name) moves data for the specified data log model, whether or not the model is running. DataLogMergeToPrimary * moves data for all data log models whether or not they are running. You can use this command anywhere you can type an RSView command or macro. If a model is running when you issue the command, RSView also performs a switchback to the primary path or ODBC database for the specified model or all running models. If a model uses file sets, RSView moves all files on the secondary path (including the current file set) to the primary path, begins a new file set on the primary path, and then continues logging to the new file set. If a model uses the ODBC 13–12

Q

RSView Supervisory Edition User’s Guide

format, RSView merges the data in the ODBC backup files into the ODBC database, and then continues logging to the ODBC database. To restore the secondary or backup data, give operators a way to issue the DataLogMergeToPrimary command at run time. For example, you can create a button object and use the command as the press action.

Using the DataLogNewFile command You can create new ODBC backup files and new file sets using the DataLogNewFile command with these parameters: or * (asterisk). DataLogNewFile (where is a data log model name) creates a new file set for the specified data log model. DataLogNewFile * creates a new file set for all data log models that are currently running. You can use this command anywhere you can type an RSView command or macro. If a data log model uses the ODBC format, the command creates a new set of backup files if RSView is logging to the backup path when you issues this command. If RSView is logging to the ODBC database, RSView logs an End Snapshot and then a Begin Snapshot when you issue this command. If a data log model uses file sets, DataLogNewFile starts a new file set regardless of when new files have been set up to start for the data log model. The new file set is created in the same location that RSView is currently logging to. DataLogNewFile records two snapshots of data: an End Record in the old file, and a Begin Record in the new file. It is not necessary to use the DataLogSnapshot command in this case. To enable operators to issue the DataLogNewFile command at run time, you could create a button object and use the command as the press action. Using data logging

Q

13–13

Using the DataLogSnapshot command You can record tag values using the DataLogSnapshot command with these parameters: or * (asterisk). DataLogSnapshot (where is a data log model name) records tag values for all tags in the specified model at the instant the command is executed. DataLogSnapshot * records tag values for all tags in all running models at the instant the command is executed. You can use this command anywhere you can issue an RSView command or macro. For example, enter the command as the action for an event. Operators can also use this command at run time. For details, see “Providing a way to log on demand” on page 13-15.

Example: Creating an event for on-demand logging To create an event that will trigger logging when an alarm occurs: 1.

Click the On Demand log trigger.

2.

Open the Event editor. Create an expression such as: If alm_in_alarm(motor_fault) and new_batch_started then 1 else 0

3.

In the Event editor’s Action field, type DataLogSnapshot where ‘component’ is the name of the data log model.

When the tag called motor_fault goes into alarm, and the tag called new_batch_started is 1, the DataLogSnapshot command runs. All tags in the model will then be logged (not just the tag in alarm).

RSView Supervisory Edition User’s Guide

About the maximum update rate The maximum update rate is the fastest rate at which event expressions in the event component can be evaluated. It also determines the fastest rate at which data servers can send changes in tag values. Set the maximum update rate separately for each event component. Set the update rate as fast as, or faster than, the rate at which the values of tags used in the expressions change, unless it is desirable to miss changes in tag values.

Editing events You can edit events during development or when you run the application. If you change the event component while running the application, the changes don’t take effect until the component is stopped and then restarted.

Starting and stopping event processing There are many ways to start and stop event processing. Choose the way that works best for the application. For an explanation of RSView command syntax, see Appendix A, RSView commands, or see Help.

How security works Security can be set up to prevent unauthorized access to certain parts of the application, or to the application itself. Access to individual commands, macros, graphic displays, and HMI tags in an application via the RSView SE client, is set up by assigning security codes to users and to application components. Only users with the specified security code can run the secured commands, open a graphic display, or write to secured HMI tags. In this way, the security code determines the user or group’s level of access to the system. Setting up security

n

15–1

At design time in RSView Studio™, or in the RSView Administration Console, a user can be granted or denied access to an application, but security for components in the application is not in effect.

Security codes RSView has 17 security codes: an asterisk (*) and the letters A through P. The asterisk is for unlimited access, and the letters are for limited access. The letters are not hierarchical—all letters provide the same level of security. You do not have to use all of the security codes, nor do you have to assign the codes in a particular order. For example, you can choose to use only the codes D and P, and you can assign P before you assign D.

Before you begin, make lists Before you begin, list: „

„

the users or groups of users requiring accounts. User groups are recommended over using individual users. the RSView commands and macros to be secured. For a complete list of RSView commands, see Help.

„

the graphic displays, OLE objects with verb animation, and tags to be secured.

Summary of the steps to set up security Complete these steps to set up security: 1.

In the User Accounts editor: „

15–2

Q

add users or groups to the RSView User Accounts list from Windows® network domains and local workstation domains.

RSView Supervisory Edition User’s Guide

„

assign a security code (A through P) to each user or group. You can assign combinations of security codes (for example B, D, and E) to users or groups, allowing each user or group to access a different set of features. If a group or user is not assigned any letters, they cannot open displays, run commands, or write to tags even if a component has an asterisk (*) assigned to it. THis is because the asterisk means codes A through P, not ‘free access’.

2.

In the Secured Commands editor, assign security codes to commands and macros.

3.

In the Graphics Displays editor assign security codes to graphic displays.

4.

In the Tags editor, set up security for the HMI tags that will require it. IMPORTANT

5.

You cannot assign a security code to data server tags, to prevent their values from being modified. To secure a data server tag, map its address to an HMI tag, and set up security for the HMI tag.

Assign a security code to the application. Only users with the specified security code can open the application in RSView Studio, or the RSView Administration Console.

Example: Assigning security codes The following security codes are set up: „

A graphic display named Boiler is assigned security code B.

„

The DataLogOn command is assigned security code D.

„

A tag named BoilerTemp is assigned security code E.

„

The application is assigned security code P. Setting up security

Q

15–3

In the User Account editor, the following security codes are assigned: „

„

The Operators group is assigned security codes B and D. The Shift Supervisors group is assigned security codes A through O.

„

Administrator is assigned all the security codes.

„

The Guests group is assigned security code B.

This means that: „

„

„

„

users who belong to the Operators group can access the Boiler graphic display and the DataLogOn command. This group can also access any graphic displays that have unlimited security assigned to them. users who belong to the Shift Supervisors group can access everything at run time when they are using the RSView SE client, but they cannot open the application in RSView Studio, or the RSView Administration Console. the Administrator has full access to the system at run time, and can open the application in RSView Studio, or the RSView Administration Console. users who log on to the system as Guest can only access the Boiler graphic display and any displays that do not have security assigned to them.

Setting up user accounts In the User Accounts editor, you create a list of the users and groups that will have access to the application, and specify the level of security for each. You cannot create users or groups in RSView. Instead, you add Windows® users and groups from Windows network domains and local workstation domains, to the RSView User Accounts list in the User Accounts editor. Any users not in the RSView User Accounts list will not have access to the secured parts of the application or be able to open an RSView SE client.

Setting up security

Q

15–5

Once you have added users to the user accounts list, specify security access for each user by assigning one or more security codes to them. Use the RSView User Accounts editor to add Windows users or groups to the list of users in RSView, and to assign RSView security codes to users and groups.

To create new users you need to set up new accounts in Windows. For details about creating users and groups in Windows, see Windows Help. To open the User Accounts editor X

In the Application Explorer, double-click the User Accounts icon or right-click the icon and then click Open.

Ensuring the administrator always has access When setting up accounts, first create a ‘super user’ account for the system administrator. Be sure to select all security codes (A through P).

Setting up default access In the forms section of the User Accounts editor, the security codes A through P are displayed in the Security Codes frame with a check box beside each. The default is for all check boxes to be selected. When you add a user to the RSView User Accounts list, the default security codes are assigned to them, which you can edit as needed. 15–6

Q

RSView Supervisory Edition User’s Guide

You can edit the default set of security codes to represent the level of access most users will have. This will eliminate the need to edit the security codes for each user or group manually. Since all users will probably not have the same level of access, you will still have to edit some user’s access manually. To edit the default user codes 1.

On the Setup menu, click Default User Codes.

2.

In the Default User Codes dialog box, clear the check boxes beside the codes that average user will not have access to.

3.

Assigning login and logout macros Each person with a user account can have a login and logout macro. Any macro component can be a login or logout macro and can contain any RSView command. For example, a login macro could contain a command to bring up a graphic display for an area of the plant. A logout macro could contain commands to redefine sensitive keys. For the login and logout macros to be executed, they must be in the area from which the Login or Logout command was executed. For more information about macros, see Chapter 22, Creating macros. To assign a login or logout macro to a user account 1.

In the User Accounts editor, click the name of the user or group to be assigned a login or logout macro.

4.

Repeat steps 1 through 3 for each user to be assigned a login or logout macro, and then click Close.

Setting up security for commands and macros In the Secured Commands editor, create a list of the RSView commands and macros whose access is to be restricted, and then assign a security code to each. Only users assigned the same security code as a particular command or macro, will have access to it. 15–10

Q

RSView Supervisory Edition User’s Guide

You can also set up security for commands using the Signature button in a graphic display to control the actions an operator can perform at run time, for example: „

setting the value of a tag.

downloading values to programmable controllers or devices.

For details about using the Signature button, see page 17-67. To open the Secured Commands editor X

In the Application Explorer, double-click the Secured Commands icon, or right-click the Secured Commands icon and then click Open.

The Unspecified_Command The first record in the Secured Commands list is called Unspecified_Command. Any commands or macros that are not in the list use the security code selected for the Unspecified_Command. You can change the security code for the Unspecified_Command. Initially, it is an asterisk (*), which means a user will have access, provided they have at least one security code assigned. A user must possess at least one security code for * access to work. Setting up security

Q

15–11

If you leave it as an asterisk, you have to list all RSView commands and macros to which access is to be restricted. This is referred to as security by inclusion. If you change the security code for the Unspecified_Command to a letter, it means that any item not in the Secured Commands list, will have that letter as their security code and only users assigned that letter will have this broad access. In the Secured Commands list, you have to list only those commands users to have access to. This is referred to as security by exclusion.

Setting up security by inclusion Security by inclusion means all RSView commands and all macros requiring security are listed in the Secured Commands editor. To set up security by inclusion 1.

For Unspecified_Command, leave the security code as *.

2.

In the Command box, type the command or macro you want to assign security to. If you assign security to the Login and Logout commands, be sure to give all users, including Unspecified_Command, access to these commands. Otherwise, users might be locked in or out of the system. It is recommended that Login and Logout keep the * security code.

15–12

Q

3.

Logging in and out Logging in at run time When the RSView SE client opens, it attempts to log the current Windows user into the client. If the current user is not in the application’s list of user accounts, the Login dialog box appears. The user name should include the domain name. If there is more than one domain in the user list, the domain name must be specified when logging in. 15–18

Q

RSView Supervisory Edition User’s Guide

If the user does not provide a domain name, the first user in the user accounts list, minus the domain name, that matches the user name in the dialog box, is verified.

The syntax for user name is: DomainName\UserName

To allow different users to log in when an RSView SE client opens, ensure you include a way for users to issue the Login command. For example, include a button that executes the Login command on the initial display. To force all users to log in when an RSView SE client opens, the account of the Windows user that is logged in must not be in the application’s list of user accounts.

Logging out at run time To allow users to log out at run time, include a way for them to issue the Logout command. For example, create a button and use the Logout command as the press action. You can also set up an RSView SE client to log out automatically after a specified period of inactivity. For details, see Help for the SE client wizard. When a user logs out, the following sequence of events occurs: 1.

All displays are closed (including cached displays).
