Modbus Gateways

Modbus Gateways or Modbus Serial Device Servers act as an interface, or 'Gateway', between Modbus devices and computer hosts running Modbus/TCP. These Gateways bridge Modbus devices to the Ethernet network and are a convenient solution to connect existing devices or controllers running Modbus/ASCII or Modbus/RTU to an Ethernet network.
