Chapter 1 ControlLogix EtherNet/IP Network Device Overview
EtherNet/IP Network
The Ethernet Industrial (EtherNet/IP) network protocol is an open industrial-
networking standard that supports both real-time I/O messaging and message
exchange. The EtherNet/IP network uses off-the-shelf Ethernet
communication chips and physical media.
If you need to Select this interface
Control I/O modules and drives
Act as an adapter for I/O on remote EtherNet/IP links
Communicate with other EtherNet/IP devices (messages and HMI)
Bridge EtherNet/IP links to route messages to devices on other networks
