Chapter 5 Communication Networks
EtherNet/IP Network
Communication
The EtherNet/IP network offers a full suite of control, configuration, and data
collection services by layering the Common Industrial Protocol (CIP) over the
standard Internet protocols, such as TCP/IP and UDP. This combination of
well-accepted standards provides the capability required to both support
information data exchange and control applications.
The EtherNet/IP network uses commercial, off-the-shelf Ethernet components
and physical media, providing you with a cost-effective plant-floor solution.
