Simulation server and the OPCClient object

The simulation server uses the OPCClient object as its basis. If your Galaxy does not include the simulation server object, you can configure one from the $OPCClient template. The OPCClient object can be used with the I/O Auto Assignment feature. In simulated environments, application objects in your Galaxy that contain I/O references are linked with the simulation server. In a production environment, these references would be linked to actual PLCs.

To use the simulation server, you must link instances to one of the simulation server's scan groups in the IO Devices view (the default scan group is Fast). The simulation server will return integer values for all supported data types. See View simulated data for the list of supported data types.

When you view simulated run-time data, a snap shot value is provided for each attribute that has I/O Auto Assignment. Since the simulation server tests I/O Auto Assignment references, references verified as good with the simulation server will automatically reconfigure when you associate the instances with the appropriate DI object and deploy the Galaxy in your actual environment.
