Usage of the PmOpcClient object requires purchase of the PmOpcClient license. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
The OPC server can be on the same or on another computer as the PROMOTIC application. If it is on another computer (see the configurator "Run on computer"), then the DCOM network service has to be set correctly. See: Configuration of the DCOM interface for OPC server.
