Dear All,
We currently using LG PLC (Type K120S; Model K7M-DR60U). The unit already has built-in RS-485 communication port. This unit then connected to Foxboro DCS via RS422/485 to FO (use MOXA product)using Modbus protocol. The problem is the Foxboro DCS didn't read data anything which send by our PLC.
I already try using Modbus tester and looks work well
Does anyone please help us to solve this problem
Thanks
