9.2 EtherNet / IP

9.2.1 Introduction

EtherNet/IP (Ethernet Industrial Protocol) is an open industrial standard that
is based on the standards for normal Ethernet (IEEE 802.3) and that expands
on them with an industrial protocol. EtherNet/IP can be used to connect
devices from different vendors to each other, as well as to have these
devices communicate with each other.
The EtherNet/IP protocol supports communications between various control
products, enabling devices to transfer time-critical application data between
each other in an industrial environment.
The spectrum of supported devices ranges from simple I/O devices (e.g.,
sensors) to complex controllers.
EtherNet/IP supports the TCP/IP protocol family and expands it for controller
applications with the Common Industrial Protocol (CIP).
CIP is used as a real-time application protocol for inputs/outputs.
