Customizing a Project using Citect​.ini Parameters

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

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

There are some common Plant SCADA driver settings as well as custom MODBUSA driver settings.

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

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