EthernetIP - EtherNet/IP Network Overview

EtherNet/IP Network Overview



The EtherNet/IP network offers a full suite of control, configuration, and data collection services by layering the Common Industrial Protocol over the standard protocols used by the Internet (TCP/IP and UDP). EtherNet/IP uses TCP/IP for general messaging/information exchange services and UDP/IP for I/O messaging services for control applications. This combination of well-accepted standards provides the functionality required to support both information data exchange as well as control applications.

Another key feature of EtherNet/IP is that it uses commercial, off-the-shelf Ethernet components and physical media. This provides a cost-effective plant floor solution using a familiar and well-understood infrastructure.

The EtherNet/IP network is most often used in these types of configurations:

• as an economical solution for connecting many computers
  
• as the best choice when you want to connect many devices
  
• as the standard network for connectivity to enterprise systems
  
• as the least expensive HMI option when used with PanelView Plus
  
• in a star topology when nodes are grouped closely together
