EtherNet/IP overview
EtherNet/IP was introduced in 2001 and today is the most
developed, proven and complete industrial Ethernet network
solution available for manufacturing automation. EtherNet/
IP is a member of a family of networks that implements
the Common Industrial Protocol (CIP.) at its upper layers.
CIP encompasses a comprehensive suite of messages
and services for a variety of manufacturing automation
applications, including control, safety, synchronization,
motion, configuration and information. As a truly media-
independent protocol that is supported by hundreds of
vendors around the world, CIP provides users with unified
communication architecture throughout the manufacturing
enterprise.
There are two common use cases of Ethernet—devices
are “human to machine” and “machine to machine.” Basic
features are presented in the pictures below.
1. Human to machine (graphical user interface, relatively
slow communication)
