Communication with Mitsubishi PLC devices
In the PROMOTIC system there are available two communication drivers via serial link
For both drivers, there is a common license PmMelsec. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
For communication of the PROMOTIC application can be used the OPC server
- see Communication by OPC interface
. Then the PROMOTIC application will communicate as a client by the OPC interface
