Port/IO Device-specific Parameters

To apply a parameter globally to every device, place it under the [OMFINS] section of the Citect.ini file.

To apply a parameter to a specific device, or every device connected to a specific port, use one of the following sections in the Citect.ini file:

• [OMFINS.<PortName>]

  • <PortName> is the name specified for the port in your Plant SCADA project.

    For example, parameters set within the section [OMFINS.PrimaryPort1] impact every device connected to the port defined as "PrimaryPort1".

• [OMFINS.<PortName>.<DeviceName>]

  • <PortName> defines the name specified for the port in your Plant SCADA project.

  • <DeviceName> defines the name of the I/O device.

    For example, parameters set within the section [OMFINS.PrimaryPort1.PrimaryIODev128] only impact the device connected to the port defined as "PrimaryPort1" and named "PrimaryIODev128."

You can set the following parameters for a specific I/O device:

• Source

• Block

• Delay

• IgnoreNonFatalError

You can set the following parameters for a specific port:

• Source

• Block

• Delay

• IgnoreNonFatalError

• Retry

• Timeout

Example

The following Citect.ini file format is an example of specifying the source parameter differently for different I/O devices communicating with the OMFINS PLC.

Assume that there are two ports in use: PORT1 and PORT2.

• PORT1 has two I/O devices attached: DEV1A and DEV1B.

• PORT2 has two I/O devices attached: DEV2A and DEV2B.

The Citect.ini file contains the following entries:

[OMFINS]

Source = 1/0/0

[OMFINS.PORT1]

Source =1/0/1

[OMFINS.PORT2]

Source =1/1/0

[OMFINS.PORT1.DEV1A]

Source =0/1/0

[OMFINS.PORT2.DEV2B]

Source =1/1/1

The resultant sources for the I/O devices are as follows:
