Modbus/TCP protocol. When user connects the serial
Modbus device running in Modbus/RTU Slave mode, the
WM-112 converter can receive connection requests from
Modbus/TCP Master device. Also when user connects the
serial Modbus device running in Modbus/RTU Master
mode, the WM-112 converter can connect to Modbus/TCP
Slave device.
