EtherNet/IP is an industrial networking standard, developed by Rockwell Automation and managed and maintained by Open DeviceNet Vendors Association (ODVA) and ControlNet International (CNI). EtherNet/IP (IP stands for Industrial Protocol), is part of the three open network standards (DeviceNet, ControlNet, and EtherNet/IP) that all use a common application layer, the Common Industrial Protocol, or CIP, while using different network media.
EtherNet/IP uses the same network media Ethernet runs over: twisted pair Ethernet cables, for example. DeviceNet runs over 120-Ohm shielded twisted pair (signal/power pairs) and ControlNet uses a low-loss, RG-6 quad-shield coaxial cable to do its work.
