EtherNet/IP to Modbus RTU Gateway

GW-7472

The GW-7472 (EtherNet/IP adapter to Modbus RTU Master Gateway) is helpful for data-exchanging between the Modbus RTU network and the EtherNet/IP network. It reads the register data from the Modbus RTU slaves and publishes these data to the input register data of the EtherNet/IP scanner. The output data transmitted by the EtherNet/IP scanner are updated to the register data of Modbus RTU slaves via the GW-7472. Through the GW-7472, all of the Modbus slaves can be regard as one EtherNet/IP adapter.
