OPCUA

The OPC UA interface is an interface between Plant Simulation and control and automation technology systems for accessing and exchanging data. It allows access to process monitors, such as PLC controls via the OPC Unified Architecture The OPC UA Interface acts as a client and can read and write control variables and the signals of PLC controls. OPC stands for Open Platform Communications.

You should run the simulation in Plant Simulation in real-time, as controls work with a real-time-timer and do not provide a fast forward function. When the PLC sets the value of a variable to right, then Plant Simulation calls a callback method in which you can react to the value from the external application.

To add the OPC UA interface to the Class Library, click Manage Class Library > Basic Objects > InformationFlow on the Home ribbon tab.
