Communication with Mitsubishi PLC devices
In the PROMOTIC system there are available two communication drivers
for the serial
communication with Mitsubishi
For both drivers, there is a common licence PmMelsec. With the freeware version PmFree, or when developing the application (with development environment for tersting purposes), this component is always functional.
The OPC server
and the PmOPCClient
PROMOTIC component can also be used for the communication. Then the PROMOTIC application will communicate as a client by the OPC interface
, i.e. by the PmOpcClient
object, the PROMOTIC will be connected to the OPC server and thus communicate with the devices.
