For the Reader
What is the purpose of this guide?
You are implementing EtherNet/IP™. Where do you start? What are your options? What issues should
you consider? What do you need to know about the protocol? How should you proceed with your
development?
This guide gives basic answers to the above questions. It provides an overview of the steps needed
to implement EtherNet/IP, and offers practical guidance to help lead you to a successful EtherNet/IP
implementation.
Who should read it?
Development engineers, development managers, product managers, and marketing will benefit from
reading this guide. You are not expected to be an expert in EtherNet/IP or the Common Industrial
Protocol (CIP™).
Technology Overview
What is EtherNet/IP?
EtherNet/IP is the name given to the Common Industrial Protocol (CIP), as implemented over standard
Ethernet (IEEE 802.3 and the TCP/IP protocol suite).
EtherNet/IP was introduced in 2001 and today is the most developed, proven and complete industrial
Ethernet network solution available for manufacturing automation, with rapid growth as users seek to
harness the advantages of open technologies and the internet. EtherNet/IP is a member of a family of
networks that implements CIP at its upper layers (Figure 1).
EtherNet/IP and CIP are managed by ODVA. ODVA publishes
The EtherNet/IP™ Specification
and helps
ensure compliance through conformance testing.
What is CIP?
The Common Industrial Protocol (CIP) is a
media independent, connection-based, object-
oriented protocol designed for automation
applications. It encompasses a comprehensive
set of communication services for automation
applications: control, safety, synchronization,
motion, configuration and information. It allows
users to integrate these applications with
enterprise-level Ethernet networks and the
Internet. Supported by hundreds of vendors
around the world and truly media-independent,
CIP provides users with a unified communication
architecture throughout the manufacturing
enterprise. CIP allows users to benefit today
from the many advantages of open networks
while protecting their existing automation
investments when upgrading in the future. CIP

Minimized investment in system engineering, installation and commissioning
Freedom to choose best of breed products, with the assurance of competitive prices and low
integration cost
The “IP” in “EtherNet/IP” refers to “Industrial Protocol”. EtherNet/IP utilizes CIP over standard IEEE
802.3 and the TCP/IP protocol suite (Figure 2). Since EtherNet/IP uses standard Ethernet and TCP/IP
technologies, it allows compatibility and coexistence with other applications and protocols.
EtherNet/IP-enabled products have been developed using pre-existing hardware platforms, with existing
TCP/IP stacks with multiple protocol support. A few vendors simply chose to provide a firmware update
to an existing Modbus TCP interface, demonstrating the ease of integration and interoperability of CIP,
without the need to develop specific hardware.
