Could you give me some project example for tia portal or advice how to establish data exchange? Navnag AutoGen_685927 I have tried with modbus TCP to modbus serial convertor, Its working fine. Now I think I dont have any choice other than replaciing it. We normally use Moxa MGate™ MB3180/3280/3480 Modbus TCP to Modbus RTU Convertors without any issues. Cheers Navnag ------------------------------------------------------------------------------------------ Split from Modbus RTU over TCP.
