Customizing a Project using Citect​.ini Parameters

The IEC870IP driver supports the following parameter categories:

• General Parameters

• Communication Parameters

• Data Interrogation Parameters

• Write Parameters

• Counter Parameters

• Time Synchronization Parameters

• Polling Parameters

• Logging Parameters

Note: At times during the life cycle of a driver, circumstances may call for the creation of specific citect.ini parameters that remain undocumented. Always seek the advice of Technical Support regarding the possible implementation of undocumented parameters before you make any changes to a citect.ini file.

Citect.ini parameters are used to tune the performance of the Plant SCADA IEC870IP driver, and to perform runtime maintenance diagnostics.

You can customize the way Plant SCADA communicates with the IEC870IP system (and even individual PLCs) by creating or editing the [IEC870IP] 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 IEC870IP configuration settings need to be included in the citect.ini file located on the computer acting as the I/O server to the IEC870IP system.

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

Note: The IEC870IP driver can be supported by an IOA configuration file that allows output points to be operated using output commands on a per-IOA basis. See Configuring Commands for Individual IOAs.

You can also set some parameters for every device connected to a specific port. See Port-specific Parameters.
