Hello to All, Friends I have Stuck to setup modbus tcp/ip communication in Mitsubishi FX5U CPU as a Master. Picture is, we have 4 Energy meters. Each Energy meter have node address and have Modbus RTU communication. We Have Connected all energy meter in Parallel with MODBUS RTU to TCP/IP Converter. We Have also Fetch the data of each Energy meter by Modbus Poll 32 software. But I need to read all this data in PLC. I know Basic how to setup Modbus, but not able to get where to assign Node address of each device, since all device connected to single IP address. Or someone Please Help to send sample program with predefine protocol program. I have done research but not able to found. Finally forum is my last hope....
