Customizing a Project using Citect​.ini Parameters

You use Citect.ini parameters to fine tune the performance of the Plant SCADA OPC driver and to perform runtime maintenance diagnostics.

• Common Driver Parameters

• Driver-specific Parameters

• Logging Parameters

• OPC Device-specific Parameters

• OPC Access Path Parameters

• OPC Status Tag Parameters

Note: Always seek the advice of Technical Support personnel for this product regarding undocumented features.

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

There are some common Plant SCADA driver settings, and custom Plant SCADA OPC driver settings.

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

Note: By default, Plant SCADA looks for the ini file in the Plant SCADA project \bin directory. If it can't find it there, it searches the default Windows directory.

The default values for these parameters have been determined by driver development and testing to be optimal for the Plant SCADA OPC driver. Parameters default to a value tested to work in common configurations. Do not adjust these default values except on the direct advice of AVEVA Global Customer Support.
