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. It emerged due to the high demand for using the Ethernet network for control applications. The EtherNet/IP network uses off-the-shelf Ethernet communication chips and physical media.

The EtherNet/IP network provides excellent drive and I/O control performance along with HMI information processing and many commercial technologies.


Select an EtherNet/IP Interface

Select the appropriate controller and EtherNet/IP interface depending on the application and how the controller interacts with the devices.

If your application uses Select for a 1769-L23x controller Select for a 1769-L3x controller Select for a 1768-L4x controller
• Controls I/O modules
• Requires an adapter for distributed I/O on EtherNet/IP links
• Communicates with other EtherNet/IP devices (messages)
• Bridges EtherNet/IP links to route messages to devices on other networks
