Object PmaOpcDaClient (OPC client)

The object connects the PROMOTIC application (as OPC client) to the OPC server.

In the PmaOpcDaClient object it is possible to create the PmaOpcDaClientGroup object where required data are defined. There can be more PmaOpcDaClientGroup objects in the PmaOpcDaClient object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
The usage of the PmaOpcDaClient object requires purchase of the "PmOPC" licence. With the freeware version PmFree, or when developing the application (with development environment for testing purposes), this component is always functional.

The PmaOpcDaClient 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 "Run on computer" configurator), then it is necessary to set the DCOM network service correctly. See: Configuration of the DCOM interface for OPC-DA server.
This object adopts properties and methods of the PmaObject object.
