Communication with PLC devices by the Yokogawa company

Basic information:

For communication of the PROMOTIC application with the Yokogawa devices the OPC server is available.

Then the PROMOTIC application will communicate as a client by the OPC interface.

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 tersting purposes), this component is always functional.
