Customize a Project Using Citect​.ini Parameters

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

• Common Driver Parameters

• Driver-specific Parameters

• OPCLX Device-specific Parameters

• OPCLX Access Path Parameters

• Status Tag Parameters

• Logging Parameters

  Note: Support for array parameters in the OPCLX driver has been deprecated in Plant SCADA version 7. To use similar functionality, you should use the procedures described in Arrays Support.

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 [OPCLX] section of the Citect.ini file for your project.

There are some common Plant SCADA OPCLX driver settings, and custom Plant SCADA OPCLX driver settings. When Plant SCADA starts at runtime, it reads configuration values from the Citect.ini file stored locally. Therefore, any OPCLX 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 cannot 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 OPCLX driver. Parameters with a default value are tested to work in common configurations. Do not adjust these default values except on the direct advice of customer support.
