How can you establish OPEN MODBUS / TCP communication via the CP343-1 or CP443-1 and where can you find further information? In communication (FC50.FC60,FC5 FC6) blocks what status word do you receive? Did you check your cable? Give us more details about what have you done? best regards

J_Bell Posts: 5822 Rating: (411)	Hello, I would mention two points to think about. Change the length at the AG_SEND in the OB1 of the CPU 315 from 4 to 100. I would strongly recommendchanging the Connection type from TCP Connection to ISO on TCP Connection. This would ease your situation a lot. Best regards J_Bell
