Ethernet: A Pocket Guide
covers just the things you need to know,
with simple terminology, concise format and vital information for control
What people are saying about
"The Pocket Guide is one of my desk
reference books since I got an advance copy of it. It is written so even
idiots like me can understand it, and use it. I think it is in the same
league as Glover's Pocket Ref, and the Pocket Pal for graphic artists. If
you work with Industrial Ethernet, you better buy this book, and stick it
in your pocket, briefcase, tool box, or whatever you carry around on the
job with you.
If you think you need to know about
Industrial Ethernet, buy this book and carry it around in your pocket for
when you have a chance to catch five minutes and read a few pages. This is
the best book published by ISA this year. And that includes my own book,
"eBusiness in Manufacturing" so that says a lot."
SPITZER AND BOYES, LLC
"Perfect Work! A
must have! I strongly recommend this book to anybody who deals with
Industrial Ethernet in any way."
Indiver Divedi, IBM
"If you have not installed or maintained an Industrial Ethernet
installation yet, you will soon and this guide is a perfect overview to
get you started as, well as a handy reference for the "expert".
This book has already helped me solve one "real world" problem
and has become part of my commissioning/troubleshooting kit."
Kevin J. Mahoney, SI Solutions
"The only problem with this book is that someone else picks it up
every time I lay it down. I'm going to order a few more so I don't have to
keep chasing this one."
Glenn Boston, Steel Dynamics
"A must-have reference guide. This book has become one of the few
reference guides I keep in my toolbox. Being a former computer network
technician (now PLC programmer and technical support) who is very familiar
with ethernet, I can say this book contains vast amounts of information
organized in a very logical fashion. It's written so even without a PC
background a reader can understand everything clearly. There are examples
and many tips to follow. It's well worth every penny."
Chris Kellock, Auburn Armature
"A pocket guide worth keeping in my pocket."
Daniel Chartier, Logitrol
"Great reference and easily understood by the neophyte. A must have
for any one working in the controls environment."
Robert Dusza, Manchester Water Department
"This has been a great book to read and will remain in the front of
book case for some time. It was great to read a book that explains the
basics very clearly and in terms anyone can understand. If you are just
learning and / or involved in a plant with an ethernet network, this book
is a must. The section on industrial ethernet protocols is a must
for someone just setting up a network. Great work, Perry."
Steve Godfrey, Weyerhaeuser
"Excellent! The chapter on basic precautions for network
security has some good guidlines that you should consider before
installing a network."
Gary Law, Emerson Process Control
"Even though I had planned on using this just for reference, I found
so many interesting things in it that I started reading it. I really
enjoyed the writing style which, unlike other books, didn't put me to
sleep. This book is easy to read and understand, even for an old timer
Dan Elsner, SMT Industries

“Finally, An Ethernet
Book For The Rest of Us!”
you’re putting Ethernet in your factory, there are some very important
things you need to know before you get started. Criteria for selecting cables, hubs, switches and network cards.
Important facts about system layout.
Questions you should always ask your vendors about application
layer protocols. Assignment
of IP addresses and best practices for maintaining a healthy system over
the long haul.
things matter a lot!
frankly there are many things about Ethernet that you don’t need
to know. You don’t need to
know how to write a TCP/IP software stack for some real-time operating
system. You don’t need a
dissertation on the inner workings of TCP, UDP or TELNET.
You don’t need a manual on designing Ethernet circuitry.
I own a few 400-500 page tomes on those subjects myself, and
although they’re important as reference tools, they mostly just sit on
the shelf. Too big.
Too heavy. And too
much information for the guy who just wants to control a machine.
things that you need to know every day should fit in a pocket-sized book,
and you’ll carry around a book like that in your pocket.
So that’s exactly the kind of book I wrote.
Whether you’re using Ethernet for I/O, linking controllers
together, or just sending production data to the accounting department, Industrial
Ethernet: A Pocket Guide gives you just the information you really
need about Ethernet and TCP/IP for automation and process control.
It fits in the palm of your hand and easily travels with you in
your toolbox or fits in a control panel.
are some of the topics that are covered in this book:
quick and dirty checklist of the questions you need to ask yourself
before you get started on a project.
very brief tutorial on digital communication – how networks work,
what the major topologies and data formats are, terminology and
definitions for the most essential system components.
What’s the difference between a protocol and a network?
What do all networks and fieldbuses have in common?
What are the major arbitration mechanisms for competing
messages? After reading this chapter you’ll be network-literate.
You’ll have a handle on the basics.
very short history of Ethernet and TCP/IP, and a rundown on all the
major Ethernet formats and terms.
You’ll know where terms like 10BASE2 and 100BASE-T come from
and which ones apply to you. How
long can a cable run be? How
many repeaters can you use in a system?
What about half duplex and full duplex?
What about collisions on the network?
What do the LED’s mean?
What information is in an Ethernet packet?
How about a working man’s definition of that 7 layer model
everyone’s always talking about?
Chapter 3 gives you just what you need about all of those
things, and closes with a handy reference on all the different
connector pin-outs, including DB-9’s and the new M12 “euro”
– Doesn’t the very term sound intimidating? TCP/IP a complex beast, but it’s also the #1 network
protocol in the world. And
there are some things you will need to need to understand – what it
does, what it doesn’t do, how IP addresses are assigned, subnet
masks, ports and sockets. There’s
a bullet list of the most important flags in a TCP/IP packet,
the major services in TCP/IP (DHCP, SNMP, FTP, TELNET and
And functional descriptions of the major utilities: PING,
Traceroute, ARP and Netstat.
Ethernet building blocks: Hubs (Workgroup, Segmented, Multi-Speed,
Managed Hubs and Repeaters), Bridges, Switches (Full Duplex,
Multi-Speed, and different ways that switches prioritize messages),
Routers, Gateways and Network Interface Cards.
and controversial issues: Determinism, the performance of software
drivers, and the cost issues of embedded “smart devices” compared
to PC’s. What are the
most likely bottlenecks for network speed?
You’ll find out in Chapter 5.
health, monitoring and system maintenance: What is it that makes a
network run well? Did you
know that studies show that the best run networks have 35 times less
down time with less staff-per-user than poorly run networks? What makes the difference?
Chapter 6 tells you how to manage the process, plan and prepare
for success, quickly isolate problems, and how to properly invest in
tools and training. It
talks about the major types of network monitoring tools and analyzers,
and their strengths and weaknesses.
It explains the importance of systematic documentation and
tells you what you should track over time.
And there’s a list of popular PC-based Ethernet utilities,
software and tools.
Troubleshooting and Maintenance Tips: Ethernet grounding rules,
linking buildings together, major cable types, reducing Electro
Magnetic Interference, and subtle issues you’ll encounter when
choosing cables. Did you
know that sometimes a higher speed cable can have worse performance
than a “low speed” cable? Did
you know that obscure issues like capacitance imbalance can wreak
havoc in your system? What
precautions should you take when pulling cables?
What about raceways with power lines?
Should you ground one end or both?
What do you do if codes require you to make less than
optic cables: What are the distance limitations? How do you clean fiber connectors? What are the major connector types?
Chapter 7 covers these topics.
Industrial Protocols, Fieldbuses and Legacy Networks: Here’s a huge
issue that’s particular to our industry.
You won’t find this information at Barnes & Noble, and
most likely you’ll find yourself cobbling together dozens of
articles from industry trade journals to fully understand the issues
in automation & process control.
Chapter 8 saves you
that time. It talks about the questions you must ask before
selecting any network, whether it’s a serial link, a fieldbus
or Ethernet. Then it
gives you a very user-friendly summary of all the major Ethernet
application layer protocols. Did
you know that Modbus/TCP and EtherNet/IP were designed with a
completely different purpose in mind than, say, PROFINet?
What’s the difference between Foundation Fieldbus High Speed
Ethernet, and the European IDA protocol?
This section tells you what these protocols do, what they
don’t do, and how they organize information.
And it tells you what to expect when it comes to compatibility
issues. The chapter
closes with a quick discussion of Embedded Web Servers and the cost
factors of Ethernet intelligent appliances.
Precautions for Network Security: How should you mix your office LAN
with your Industrial Control LAN?
Where do problems most typically come from?
Guess what: The most probable source of disasters for you
isn’t likely to be a hacker in Budapest – it’s well-intended but
mistaken actions taken by your own staff.
Chapter 9 covers the most likely scenarios and tells you how to
on Ethernet: Did you know that the telecommunications industry has
developed a clever method for powering Internet Appliances with
existing Ethernet hardware? There’s
a brief appendix that points the way to powered automation devices.
book is certainly not the last word on Ethernet, TCP/IP or all the
possible issues that you might encounter in automation.
And it’s probably not the only Ethernet book you would ever care
to own. However, I bet
you’ll refer to this book more often than most of the others, and a few
months from now the pages will be dog-eared with use...and isn’t that what you’re hoping for whenever you buy a book?
Industrial Ethernet: A Pocket Guide and you’ll have your hands on
a simple, concise, informative reference tool for designing, installing,
maintaining and trouble shooting real-world Ethernet networks!
