Communication with Yokogawa PLC devices

Basic information:

For communication of the PROMOTIC application with the Yokogawa devices the OPC server is available (information from the year 2006).

Then the PROMOTIC application will communicate as a client by the OPC interface, i.e. by the PmaOpcClient object, the PROMOTIC will be connected to the OPC server and thus communicate with the devices.

Usage of the PROMOTIC OPC client component 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.
