Customizing a Project using Citect​.ini Parameters

Citect.ini parameters are used to tune the performance of the Plant SCADA OPC UA driver, and to perform runtime maintenance diagnostics.

You can customize the way Plant SCADA communicates with the OPC UA system (and even individual PLCs) by creating or editing the [OPCUA] section of the Citect.ini file for your project.

When Plant SCADA starts at runtime, it reads configuration values from the Citect.ini file that is stored locally. Therefore, any OPC UA configuration settings must be included in the Citect.ini file located on the computer acting as the I/O server to the OPCUA system.

• Connection Parameters

• Subscription Parameters

• Security Parameters

• Logging Parameters

Note: Any parameters placed under the [OPCUA] section of the Citect.ini file will apply globally to every device using the OPCUA driver. However, you can also set parameters for a specific device, or for every device connected to a specified port. For more information,see Device-specific Parameters.
