Communication with PLC devices Telemecanique

For communication of the PROMOTIC application with PLC devices Telemecanique by the Schneider-Electric company (, for example, the following methods can be used:

Communication by the Modbus protocol

The Telemecanique devices support the communication by the Modbus protocol.

For this communication in the PROMOTIC system can be used: PmModbusMr - Driver for communication by the Modbus Master protocol.

For easy integration of this driver into the application it is handy to use:
For this driver, it is recommended to set the configurators:
- PmaCommGroup > Parameters > Special Parameters > Area base addresses:
- base address "Bo = Coil/output bits" = 1
- base address "Bi = Input bits" = 10001
- base address "Ro = Holding/output registers" = 40001
- base address "Ri = Input registers" = 30001
- PmaCommGroup > Parameters > Special Parameters > Max. number of variables received in one message:
- max. number "Bo = Coil/output bits" = 64
- max. number "Bi = Input bits" = 64
- max. number "Ro = Holding/output registers" = 32
- max. number "Ri = Input registers" = 32

Communication by OPC server

An OPC server can also be used for these PLC's (for example by the Schneider-Electric company) - see Communication by OPC interface. Then the PROMOTIC application will communicate as a client by the OPC interface.
