OPC Client Driver

Setting the Poll Rate

Selecting a poll rate to use depends on whether you are using asynchronous or synchronous I/O.

Poll Rate and Asynchronous I/O

If you are using asynchronous I/O, we recommend setting the poll rate to 5 minutes (5:00). Also selectthe Enable Asynchronous Watchdog check box so that the client can periodically request data from theserver. If you do not select this check box, the client must rely on asynchronous callbacks from theOPC server in order to refresh its data cache.

Poll Rate and Synchronous I/O

If you are using synchronous I/O, set the item’s poll rate shorter than your scan time. For example, ifyou have a database block with a scan time of 10 seconds, set the poll rate for the item it accesses to 5seconds. Likewise, set the update rate to be shorter than the scan time and the poll rate.

Keep in mind that if you set poll and update rates for groups to values that are shorter than needed, youimpose unnecessary stress on your system.

Example

• Database block scan time: 10 seconds

• Poll Rate: 5 seconds

• Update Rate: 2 seconds

Using a Zero Poll or Update Rate

Setting the poll rate to zero forces the driver to run at its maximum rate.

Setting the update rate to zero requests the OPC server to update its group at its maximum rate. TheOPC server will return the actual, or revised, rate that it can run at. This revised rate is displayed in theActual Rate field on the group’s statistics display in the OPC Client’s Power Tool.

The Most Common I/O Driver Problems

Some of the most common problems encountered when setting up and using I/O drivers are caused byone or more of the following:

• Failing to match the communication parameters of the process hardware in the OPC server.For information about appropriate values for these fields, consult your OPC server’sdocumentation.

• Failing to run SAC. You cannot access data from your I/O driver in the Event Viewer or theiFIX WorkSpace until SAC is running.

OPC Client Driver

• Attempting to communicate to areas of memory not defined in the controller. Verify that eachitem’s address is valid.

• Setting an item’s access time to be larger than its poll time so that OPC Client never polls fordata.

• Not enabling the server, group or item in the OPC Client.

• Leaving the item ID blank.

Tools for Troubleshooting the OPC Client

• View the I/O Server program in the I/O Server

• Close the I/O Server program

Statistics View in the OPC Client Power Tool

The Power Tool displays communication statistics for each item, group, server, and the entire driver.Displaying these statistics is useful for narrowing down which part of the driver is not functioning. Toview the statistics, select an item, group, or server from the Tree Browser and then select Stats Modefrom the Display Mode menu.

Statisti cs in iFIX Mission Control

Mission Control is the main iFIX tool for monitoring background tasks, such as SAC, HistoricalCollect, and I/O drivers. Using Mission Control, you can start and stop a driver, and view driver errornumbers. This is useful for quickly determining if the driver is having a problem.

Mission Control also provides a summary of driver-level statistics. To see the statistics for each server,use the OPC Power Tool.

Windows Event Viewer

The driver reports any major errors to Windows Event Viewer. To learn more about using thisapplication, refer to Using the Event Viewer.

Alarm History in iFIX

Because the I/O driver reports event messages to the Alarm History application in iFIX, you can usethis program for debugging your driver. The events reported include when the driver:

• Starts and stops.

• Connects and disconnects.

• Fails to connect with the OPC Server and subsequently recovers.

Refer to the iFIX documentation for details about enabling alarm services.

OPC Client Driver

Message Log in the I/O Server Program

The message log in the I/O Server program tracks the following events:

• The date and time a configuration file loads.

• Which configuration file loads. If the driver is not loading the configuration file you want,you can change the default file name and location in the Power Tool’s Setup dialog box.

• The date and time other applications attach to the server. This data can help you determine ifsomeone is attached and making changes to the server you are working on.

• CSV import errors.

To view t he I/O Server prog ram in the I/O Server:

1. Open the Power Tool.

2. Select an object from the Tree Browser.

3. Press A LT + SHIFT + S.

The options in the Server’s View menu let you choose the types of messages to display. The message priority is as follows:

Server View Displays...

Errors Connection errors, run-time errors, and any exceptions caused by the driver orOPC server.

Warnings General warnings.

Information General information such as loading files or .CSV activity.

Debug1 The connection status of the driver to an OPC server when the server isenabled. Debug1 messages also contain information about any OPC interfacethat was not obtained when the driver connected to the OPC server.

Debug2 Information about asynchronous transactions between the driver and the OPCserver.

Debug3 Information about failed writes to the OPC server.

OPC Client Driver

The default setting for the Server is to display errors, warnings, and informational messages. However,you can also enable any debug message you want more information about.

To close the I/O Server program:

1. Select an item from the Tree Browser.

2. Press Alt + Shift + S.

iFIX Process Database Log File

The driver reports all actions performed to add items and database blocks to the iFIX process database.For more information, see Use the iFIX Process Database Log File.

Use the Windows Event Viewer

GE Intelligent Platforms’s Version 7.x drivers take advantage of a Windows feature known as the

Event Viewer. This feature allows software to write messages and data to the Windows Event Log.These messages can then be viewed using the Windows Event Viewer application. Version 7.x driversuse this ability primarily to log information about problems that arise during execution, particularly inthe lowest layers of the driver where reporting the problem to users is more difficult. It also allows themessages logged to include specific information about the error. For instance, if the memory objectencounters a problem while mapping an area of global memory via the "CreateFileMapping()" Win32function, it not only reports that the error happened, but it can also translate the error code returned byWindows and include that text as well.

The Windows Event Viewer contains three different categories of messages: System, Security, andApplication. The OPC Client writes its messages to the Application log.

To view messages that mi ght b e generated by the driver:

1. Start the Windows Event Viewer.

2. Select the Application log from the Log menu. All the log messages associated with theApplication log appear. Any message specific to your driver contains the driver’s acronym(OPC) in the Source column.

3. Select a message and press the Enter key;

- Or -

Highlight a message and choose Detail from the View menu;

- Or -

Double-click the message.

Information that may be helpful for troubleshooting your I/O driver includes:

• Time – The time that the message was logged.

• Computer – The name of the computer that the message was logged on.

• Type – The severity of the message. Options include: Error, Information, and Warning.

• Description – The actual message logged.

OPC Client Driver

• Data – The specific data associated with the message. The OPC Client rarely uses thisinformation.

Error Codes

Creating a Custom Client Application

The OPC I/O Server is an OLE application that you can control programmatically. It exposes itsfunctionality to other OLE applications through its interfaces, which means you can create customOLE applications to access or control the driver. For example:

• You can use Visual Basic to programmatically enable servers, groups, or items depending onuser input.

• You can use VBA in Excel to create a program that generates reports comparing groupstatistics within a driver.

OPC Client Driver

• You can write programs that control the driver with higher performance using C or C++.

Refer to the following topics for steps on getting started with creating custom applications:

• Creating a Custom Application Using Microsoft Visual Basic

• Creating a Custom Application Using C or C++

Create a Custom Application Using Microsoft Visual Basic

Microsoft Visual Basic is one of many applications that you can use to develop custom OLEapplications for use with the OPC Client.

To start designin g a Visual Basic application t hat accesses the OPC Client objects:

1. Start Visual Basic and from the Projects menu, choose References. The GE IntelligentPlatforms OPC Client 7.10 Library should display in the Available References list box. If itdoes not, browse your directories for .TLB files and add OPCDRV.TLB to the AvailableReferences list box.

2. From the View menu, choose Object Browser and then from the Libraries/Projects list at thetop of the browser, select OPCDRV.

3. Select a property or method and press F1 to learn how to use it.

The type library, OPCDRV.TLB, is installed in the same path that you installed the OPC Client.

NOTE: To use Visual Basic for Applications (VBA) instead of the VB Compiler, select References fromthe Tools menu in step 1 and follow steps 2 and 3 above.

Create a Custom Application Using C or C++

You can create a custom client application for use with the I/O Server using Microsoft Visual C orC++.

To get started creating an client applic ation wi th C or C++:

1. Add a call to CoCreateInstance to load the server and get a pointer to the driver interface.

2. Include InterfaceDef.h in the source from your driver.

3. Add Interfacedef_i.obj to the project.

You can obtain copies of InterfaceDef.h and Interfacedef_i.obj from GE Intelligent Platforms. Contactyour local sales representative for more information.

The OPC Client as a Data Source in iFIX

Refer to the following sections for more information regarding Data Sources in iFIX:

OPC Client Driver

• Access the OPC Client as a Data Source in iFIX

• Access String Data with the OPC Client

Access the OPC Client as a Data Source from iFIX

You can access any item in the OPC Client as a data source in iFIX. Using this method, the valuesfrom your OPC server can be displayed directly to an operator without the overhead of using the

process database. Typically, this approach is best when you only want to display the data and do notneed to alarm or historically trend the information.

To access an item in t he OPC Client as a data source:

1. Configure the OPC Client as needed. For more information about configuring the client, referto Choosing a Method for Configuring Your Driver.

2. Register the OPC Client as a data server with the Data Server Installer.

a. From the Base path (C:\Dynamics, by default), double-click the icon for the DataServer Installer (DataServerInstaller.exe).

b. Click Add or double-click the data server you want to modify.

c. In the Data Server box, enter a name. Make sure the name is not already in use.

d. From the OPC server list, select an OPC driver.

e. Select the Set as Default Server check box to make the server the default.

3. Start iFIX and add a Data link to any picture you have in your Pictures folder. The Data linkdialog box appears.

4. Click the Browse button to the left of the Source field. The Expression Builder dialog boxappears.

5. Click the Data Servers tab.

6. Select the OPC Client and navigate to the item you want to use.

7. Click OK to accept your selection and close the Expression Builder.

8. Click OK to close the Data link dialog box.

Access String Data wi th the OPC Cli ent

You can read string values in the OPC client by using the following syntax as your data source:

• server;group;itemid|bytes (ASCII values)

Where:

• server is the name of the OPC server you want to access.

• group is the name of the group that you want to read data from.

• itemid is a itemID of the string data to read.

• bytes is the number of bytes (characters) you want to read. Specifying the number of bytes isoptional. When omitted, the client reads 20 bytes. You can specify a maximum of 256 bytes.

OPC Client Driver

SAC – The Scan, Alarm, and Control program (SAC) is a iFIX system task that runs on a SCADAserver. SAC transmits and receives data back and forth between the process database and the I/Odriver’s common memory.

• SAC performs the following tasks:

• Fetches data from the I/O driver’s common memory.

• Translates the data into the format expected by the process database.

• Checks the data against the alarm limits and generates alarm messages.

• Executes the control logic.

• Detects exceptions.

• Makes requested writes to the driver’s common memory.

Signal Conditioning – The method by which a raw process data value is scaled.

SIM Driver – An I/O driver used to simulate input and output of the process database for iFIXapplications. SIM values are saved in the process database itself but are cleared when SAC is started or

when you reload the process database. SIM registers range from 0 to 2000 for analog values and 0:0 to2000:15 for digital values.

Time-Based Scan Time – With a time-based scan time, SAC retrieves data at set time intervals. Usetime-based scanning when your data changes frequently.
