You have almost nothing to do. The soft PLC includes with So Machine is modbus TCP server and it uses internal boolean variable %Mi. If in your FIO scene with the driver modbus TCP client, you use for instance “coil 3” for one sensor (input), it is going to be %M3 for So machine. In addition, if you use “input 17” for one actuator (outputs), it corresponds to %M17 in So Machine. The one and only thing to do is to take different adresses for FIO inputs and outputs in the configuration of the driver modbus TCP client.
Do not hesitate if you have any problem.
