Industrial
Ethernet - The use of Ethernet as an industrial network
is a subject for which still very little documentation is available. This
publication focuses entirely on this type of usage of Ethernet, and how this
relates to the operation of Ethernet. A difference between an office-user of
Ethernet and an industrial user of Ethernet is that the former is not interested
in (seemingly trivial) details of internal Ethernet operation, while the latter
must sometimes know all the details in order to assure that the network operates
correctly under all circumstances. Despite many publications in the trade press
about industrial Ethernet, it is difficult to find relevant technical
information void of marketing hype and commercial interests. This excellent 100
page publication addresses this - thanks to Rob Hulsebos
Industrial
Ethernet -Another Emerging Technology
The
Industrial Ethernet University- The purpose of the university is to educate
the public on the benefits of deploying Industrial Ethernet in a variety of
solutions for applications. Students will be taught the basics of Industrial
Ethernet from the physical and data link layers up through the network,
transport and application layers. The material presented will be vendor-neutral
since the purpose of the university is to educate the public for the benefit of
the industry. The cost of this...free.
The
Case for Industrial Ethernet - From "the Industrial Ethernet Book"
Charles
Spurgeon's Ethernet Web Site- This site provides extensive information about
Ethernet (IEEE 802.3) local area network (LAN) technology. This includes the
original 10 Megabit per second (Mbps) system, 100 Mbps Fast Ethernet (802.3u),
1000 Mbps Gigabit Ethernet (802.3z/802.3ab), and 10 Gigabit Ethernet (802.3ae)
Industrial
Ethernet Handbook for Engineers - Engineers working to
understand the nuances of Ethernet topologies, interconnection schemes, and
application guidelines will find HARTING’s Industrial Ethernet Handbook a
valuable engineering reference source. The detailed, 168-page handbook covers
the technical details of Ethernet, comparing it to other fieldbus systems, and
explaining its Open System Interconnection (ISO/OSI) Reference Model. Its Annex
details pertinent standards and application guidelines, such as EN, IEEE, IEC,
UL, and HD/VDE. This Annex also contains an extensive bibliography on fieldbus
and Ethernet technology, along with Internet links to other resources.
The HARTING Handbook explains:
• Open System Interconnection (ISO/OSI) Reference Model
• Comparison of Ethernet to other fieldbus systems
• Power over Ethernet (PoE) connectivity
• 26-page glossary of terms/acronyms
Ethernet
Basics - This Industrial Ethernet Basics Guide defines
all of the basic network building blocks like hubs, switches, routers, bridges,
terminal servers and gateways; it explains issues in selecting cables for
demanding applications, and issues regarding software drivers and network speed.
It explains network design rules for hubs and repeaters; and it explains the
7-Layer networking model in plain English - from B&B Electronics.
The
Ethernet Buzzword Guide - This Guide gives you the
lowdown on network & TCP/IP Terms: What does 10BASE-T mean? How about half-
and full- duplex? What's the difference between a hub and a switch? A port and a
socket? What is CSMA/CD?
You'll find answers to all these questions, and concise definitions on this
simple 3-page guide - from B&B Electronics.

Redundancy
in EtherNet/IP systems - Alain Grenier - As with any
Ethernet-based industrial protocol, in EtherNet/IP, redundancy—the repetition
or duplication of messages to circumvent transmission errors—is required to
maintain maximum uptime while still enabling the system to deal with minor
outages and potential failures to the environment. Redundancy plays a critical
role in determining the reliability of the entire system, from the very edge
devices, through the network core, to the plant backbone - from ISA.

Power
Over Ethernet - POE is a technology that provides
electrical power to a Powered Device using conductors in a CAT5 cable. Power is
delivered by means of a DC voltage and maximum current rating. Typical Power
Sourcing Equipment devices are network switches. Even though there is a standard
(IEEE 802.3af) there are a number of factors you should watch for as this
technology emerges and evolves because as usual the devil is in the detail -

to access them.
Industrial
Ethernet, an Introduction - Industrial Ethernet use is
growing rapidly. If your plant does not already use it, chances are good
that it will soon. Prepare yourself by understanding the basics of
Ethernet.
Industrial

first and second of a three-part series on the basics of Ethernet, especially as
they relate to industrial automation.
Industrial
Ethernet, Advanced Ethernet Architecture -This is the
third in a three-part series to give you the basics of Ethernet, especially as
they relate to industrial automation.

PROFINET proxies, creating an all-encompassing network architecture that brings
the now ubiquitous industrial Ethernet into the process plant.

Ethernet
on the Floor - There is a proper time and place for industrial
communications deployment - Mark Fondl - There is no doubt about
it: Ethernet continues to grow from year to year throughout the automation
industry. But the real issue is why aren't users adopting it at a more rapid
pace? From the InTech and ISA.
Industrial
network integrity- New-era industrial network communications require fresh
skills and tools -Ian Verhappen and Eric Byres - If the
reliability of the process rides under a veil of question and uncertainty, there
is big trouble. With industrial communications networks playing a critical role
in today’s control systems, it is vitally important these networks have the
highest level of reliability possible - from the ISA and InTech.
Ethernet
Based Instrumentation - While extending Ethernet
to a PLC or DCS I/O block is very common, the idea of using it to connect to
individual process or discrete sensing devices is relatively rare. But is that
assessment changing? In this article, Control Engineering magazine's Peter
Welander discusses the role of Ethernet based instrumentation in device-level
networks.- from Control Engineering and Moore
