I need to make a serial connection between a modicon 984-145 CPU and a win95 PC running modsoft. but I'm having no joy, keep getting error 199..revise modbus address...
I know the modbus address is correct.
I've no problem using an old pre windows laptop running the same version of modsoft to talk to the same CPU using the same modbus address with the same comms lead. Why won't the win95 PC talk to the CPU? Any suggestions would be greatly appreciated.
