Communication with Telemecanique PLC devices
For the communication of the PROMOTIC application with the Telemecanique
from the Schneider-Electric
the following methods can be used:
Communication by Modbus protocol
devices support the communication by the Modbus protocol
For this communication in the PROMOTIC system can be used: PmModbusMr - Driver for communication by 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:
Communication by OPC server
An OPC server
(e.g. from the Schneider-Electric
and the PmOPCClient
can also be used for these PLC's.
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.
