System Requirements

Each Plant SCADA I/O server needs to have a local installation of OPC Factory Server (OFS) version 3.33 or later.

Version 1.02.12.001 (or later) of the OFSOPC driver will only use the #PLCQualStatus tag to determine the status of a device.

OFS configuration file locations

At startup, the OFSOPC driver might need to access the OFS configuration file DeviceConfig.xml to gather push data information.

Once OFS has been installed, this file can be found in the following directory:

%PROGRAMDATA%\AVEVA Plant SCADA 2020 R2\OFS\<ver>

Where <ver> is the version of OFS installed.
