Using Unslave as a Modbus TCP Simulator

A concept of mode has been introduced. Unslave can now operate either in RTU or TCP mode. In RTU mode it will function as a Modbus RTU slave and listen to the serial port specified in config.json:

{
    "mode": "RTU",
    "port":{
        "name":"COM1"

        ...
    }
}

To activate TCP, simply change mode to TCP. The serial port settings will be ignored and Unslave will operate as a Modbus TCP node:

{
    "mode": "TCP"
    ...
}

Unslave uses the default Modbus TCP port - 502, unless you specify a different tcpPort in config.json:

{
    "mode": "TCP",
    "tcpPort": 9000
    ...
}
