Does Unity Pro simulator supports Modbus communication.

How can we help you today?

The PLC simulator only supports TCP/IP based communication (Schneider Port 502). In other cases a Modbus error is returned. Modbus, Modbus Plus or Uni-TE are not supported by the PLC simulator. The PLC simulator has no communication timeout and communication network such as Uni-Telway, Ethway, Fipway, Modbus, Modbus Plus, etc., are not supported by the PLC simulator.
