DS6x00 EtherNet/IP Scanner 

Rev  1.02 

 

II. EtherNet/IP 

Overview 

 

A LITTLE BACKGROUND 

 

Most people who work in an office associate the term “Ethernet” with the physical cable behind 
their desk. This cable connects their office PC to the printers and servers of the local network and 
the infinite web sites on the Internet. This cable is only the physical part of Ethernet, the media 
carrying Ethernet messages to your PC. On this wire is a whole series of communication 
protocols such as IP, the Internet Protocol; TCP, the Transport Control Protocol; and various 
Microsoft protocols such as NetBEUI. This suite of protocols works well for the office 
environment. It allows users to share files, access printers, send email, search the Internet and 
perform all the other communications used in the office environment. 
 
The needs of the factory floor are much different with some very special requirements. Instead of 
accessing files and printers, factory floor controllers must access data embedded in drive 
systems, operator workstations and I/O devices. Instead of letting a user wait while a task is 
being performed, factory floor data communications needs are real-time or very close to real 
time. Terminating the fill operation on a bottle requires much more time-precise communications 
than accessing the next page of an Internet site. 
 
Traditionally, Ethernet had only limited acceptance in Industrial Automation. Until recently the 
expense, lack of intelligent switches and routers and the domination of large vendors with 
proprietary protocols prevented the wide acceptance of Ethernet on the factory floor. Now with 
prices falling, PCs with inherent Ethernet capability moving in droves onto the factory floor and 
intelligent switches and routers, Ethernet is gaining acceptance. Only the lack of a widely 
accepted, flexible application layer targeted to Industrial Automation has prevented its complete 
acceptance. 
 

ETHERNET/IP 
 

Ethernet/IP is the application layer protocol that can meet this challenge. Four independent 
groups have joined forces to develop and promote EIP as a public domain Ethernet application 
layer for Industrial Automation. These groups include the Open DeviceNet Vendor Association 
(ODVA), the Industrial Open Ethernet Association (IOANA), Control Net International (CI) and 
the Industrial Ethernet Association (IEA). The goals of this effort illustrate how EIP provides a 
wide-ranging, comprehensive, certifiable standard suitable to a wide variety of automation 
devices: 
 
Ethernet/IP uses all the transport and control protocols used in traditional Ethernet including the 
Transport Control Protocol (TCP), the Internet Protocol (IP) and the media access and signaling 
technologies found in off-the-shelf Ethernet interface cards. Building on these standard PC 
technologies means that EIP works transparently with all the standard off-the-shelf Ethernet 
devices found in today’s marketplace. It also means that EIP can be easily supported on standard 
PCs and all their derivatives. Even more importantly, basing EIP on a standard technology  
platform ensures that EIP will move forward as the base technologies evolve in the future.
