EtherNet/IP Overview
Ethernet Industrial Protocol (EtherNet/IP) is a frame-based computer
networking technology for local industrial area networks. It follows the seven
layers of the Open Systems Interconnection model:
Use of the Common
Industrial Protocol
EtherNet/IP implements the Common Industrial Protocol (CIP), the
application layer protocol specified for EtherNet/IP.
EtherNet/IP uses the CIP on the process layer. The 842E encoder meets the
requirements of the EtherNet/IP protocol according to IEC 61784-1 and the
requirement of the encoder profile.
