EtherNet/IP is one of the open network standards, like DeviceNet and ControlNet. It is an industrial application layer protocol for industrial automation applications. It uses all of the protocols of traditional Ethernet including the Transport Control Protocol (TCP), the Internet Protocol (IP) and the media access and signaling technologies.
EtherNet/IP converters and gateways are useful in transferring data between Modbus RTU, Modbus TCP, and EtherNet/IP networks. Data is read from the registers of Modbus RTU slave devices and Modbus TCP servers and fed into the input registers of EtherNet/IP scanner devices.
