Object PmOpcClient (OPC client)

The object connects the PROMOTIC application (as an OPC client) to the OPC server.
In the PmOpcClient object it is possible to create the PmOpcClientData object where required data are defined. There can be more PmOpcClientData objects in the PmOpcClient object. This object can be created in the PmRoot, PmFolder and PmPrototype objects. Multiple objects of this type can be created in such objects.

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 PmOpcClient object can be connected to the OPC server. For the OPC standard description see Communication by OPC DA interface.

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.

This object adopts properties and methods of object PmObject.
