Sir I want to communicate 2 different plc, Siemens S7-1200 with Omron CJ2m, I've been write function block MTCP_ETN_Server(modbus server in Omron cj2m) and MB_CLIENT(modbus client in Siemens S7-1200) but it's not still connect/transfer the data. Should i use another device to connect 2 different plc like prosoft(profibus) or ethernet to profinet converter? does anyone can help me to solve this problem or have example/documentation program? ------------------------------------------------------------------------------------------ |

hi, Do you have any errors on the MB_CLIENT block? You could also use a converter, but it should be possible without it. There is a application sample for Modbus TCP in S7-1200 controller: How do you program and parameterize Modbus/TCP communication between two S7-1200 CPUs? hope this helps, regards, |
