6.2 Modbus Net ID
The tGW-700/GW-2200 series module is a gateway that can be used to convert between the
Modbus TCP/UDP protocol and the Modbus RTU/ASCII protocol. Consequently, SCADA/HMI
applications is able to access each Modbus RTU/ASCII slave device via the tGW-700/GW-2200
gateway by specifying correct Net ID of the intended slave device in each Modbus TCP request.
Note that the Net ID of the tGW-700/GW-2200 gateway is reserved for specific control purposes, and is
not used to access slave devices.
