ORSO2001 Posted February 24, 2018 Report Share Posted February 24, 2018 Dear Alls, I have to set up my Unistream to works at same time as Slave by Modbus RTU TCP and Masert by Modbus RTU RS485. I already wrote the program part about slave (Modbus TCP) than I set PLC communications->Protocols->MODBUS->Slave->Panel Ethernet...I have set the registers and "wrote" the code...now I am approcing the Slave side...my question is: I must use/set the same PLC communications->Protocols->MODBUS->Master->RS485 or I can mix/use the first with the PLC communications->Physical->Serial COM ? I hope that my qestion is clear enough. thanks Quote Link to comment Share on other sites More sharing options...
