Overview

ControlLogix Network Device Features

EtherNet/IP™ networks are communication networks that offer a
comprehensive suite of messages and services for many automation
applications.

This open network standard uses commonly available Ethernet
communication products to support real-time I/O messaging, information
exchange, and general messaging.

The ControlLogix® EtherNet/IP network devices:

• Facilitate high-speed data transfer between some Logix 5000™
controllers and remote I/O modules.

• Connect to multiple EtherNet/IP network topologies.
