About The Book of CODESYS

[GaryPratt]

The Book of CODESYS is the ultimate guide to PLC programming with the CODESYS IDE and IEC 61131-3. The Book of CODESYS is a self-paced version of the highly rated CODESYS Intensive Training Course, in a significantly lower cost format. This book serves as both a training manual with over 60 hours of detailed instructional text, graphics, and lab exercises; and as a comprehensive reference book with an online full-text search.

The Book of CODESYS makes extensive use of detailed graphics to help new users transition to CODESYS while also providing substantial detail, tips, and best practices for experienced users wishing to take their expertise to the next level. It includes numerous structured and unstructured hands-on labs to solidify the knowledge gained in each chapter. The Book of CODESYS points out the best aspects of each IEC 61131-3 language and where each is best applied, covers traditional PLC programming as well as next generational techniques, and is applicable to all controls industry segments.

With over 7000 hours in the making, The Book of CODESYS is the most comprehensive CODESYS and IEC 61131-3 training and reference resource available. In book form, it is much easier to skip over areas already mastered, reread areas for better understanding, and skim for specific pieces of information. The Book of CODESYS is ready to help you in every stage of your mission to master CODESYS and IEC 61131-3.

A sample chapter and lab, detailed table of contents, full-text search, lab files, and other supplemental material are available at www.BookOfCodesys.com. An instructor package is also available to qualified educators.

CODESYS and IEC 61131-3 are leading the charge towards platform independence in the automation industry (similar to the same advance in the PC and Smartphone industries of the 1980s and 2000s). The Book of CODESYS is a key resource to gain an early lead in this market shift.

About the Author
Gary Pratt is a licensed Professional Engineer and president of ControlSphere Engineering. He began his career in 1982 designing instrumentation and control systems for Chevron Corporate Engineering in San Francisco. Gary ventured into PCB/FPGA design for medical imaging systems and marketing for integrated circuit design tools before returning to his roots in instrumentation and controls on the first PLC system to control a GE gas turbine engine. From there Gary discovered CODESYS and its significant superiority over other development systems and became an instant evangelist - first for an innovative manufacturer of an extreme cyber secure CODESYS-based PLC, and eventually serving as founding president for CODESYS North America. These days Gary dedicates his time to passing his knowledge on to the next generation and helping CODESYS users get started in the right direction.

Dear Sir,

I get this information from LinkedIn and there is no so many books to explain about PLC,IEC61131-3.
My location is in japan and i am really very like to play with codesys..!
I am finding way to buy the book and ship it ..
Anyway, please keep to go forward!
Having a good day.

Irasshaimase ChrisChung,

Thank you for your interest in The Book of CODESYS. Please send an email to "sales at bookofcodesys dot com" with your mailing address, and I will respond with the current purchase and shipping options for Japan.

Unfortunately, the book is too big to qualify for international distribution, but in February, a two-volume version of the book will become available for international distribution. Your favorite online retailer in your country should be able to get you those books. Volume 1 retails for $195 and Volume 2 for $185.

I take this change to thanks Gary for fixing the login to this forum.

I am 61 years old and working on controls in-and-out for some 20 years. I tried to self-learn ST on IEC61131-3 a year ago with CODESYS version 2.3 on my Win2000 laptop, and a lot of Googling, but the learning curve is not picking up. This is why I bought The (ultimate) Book of CODESYS. I am reading Chapter One and it is just fascinating.

The first thing in my mind -- is it possible to port CODESYS IDE to Linux.

Best regards,
Patrick

Hello Patrick.
I'm pleased you are finding value in the book.
There are runtimes available for Linux on X86 and ARM. The IDE only runs on Windows. I believe CODESYS has a long-term plan for some sort of web-based IDE, but I don't believe that will be out anytime soon. For now its Windows or a Windows VM on Linux.

My first goal is to learn how to map I/O as array.
Array on Chapter Three is of great feature, but I yet found it out in the Book.
I use to command pumps from Lead to lags like:
/
task main

FOR R := 1 to NOE DO

IF ( R <= NOPD ) THEN
PC[ PTR[R] ] = 1 ; // start pump
/ delay 5-seconds
ELSE
PC[ PTR[R] ] = 0 ; // stop pump
/ delay 2 seconfs
ENDIF

End_For

endtask
/

Where:
R is index
NOE is number of equipment (count)
NOPD is number of pump demand
PTR holds the equipment-ID ... PTR[1] that holds 3 means Lead is pump-3 ... PTR[2] is First Lag
PC is the physical pump ... PC[1] is pump-1; PC[2] is pump-2 ...

The Traffic-light logic in P95, Chapter Five
Text in illustration is so small that I cannot read in naked eye, that I have to use magnify glass (back and forth) multi times to retype the ST code:

Inspect := (( GrantyCmdLeft AND GrantyIsLeft ) OR
( GrantyCmdRight AND GrantyIsRight ) OR Manual )
AND ( Interlock OR Override ) AND ItemPreset;

I use to format text in graphical hirachy:

Inspect := ( ( GrantyCmdLeft AND GrantyIsLeft )
OR ( GrantyCmdRight AND GrantyIsRight )
OR Manual
)
AND ( Interlock OR Override )
AND ItemPreset;

This chapter has mentioned accurately -- engineers tend to be graphically oriented ...
My colleaques use to hand me hand drawings, then I code them all in text, like that above.

Have a nice day,
Patrick

Hello Patrick,

Thank you for your input.

I am not aware of any way to map I/O data as an array, if the I/O vendor has not set up their Device Description file to accommodate arrays. The data type of your destination variable must match exactly the data type that is specified on the I/O mapping tab. You could map the data to a Union, and then map that to an array (similar to the remapping mentioned in the Union section of the UDT/DUT chapter). But, that is a two-step process. I am working on a way to completely bypass the I/O tree (parameterized section of the device tree), and provide the programmer with complete control on how they want to map the I/O (as well as to allow I/O changes in an online-change, and to allow I/O to be more object-oriented). Please subscribe to ooip-foundation.org to be notified when that library becomes available.

As I mention in the Preface section, I do admit to struggling with the tradeoff between consolidating information and readability. I personally find it easier to understand a single overly-detailed graphic versus spreading the information over several graphics and then swapping back and forth between the graphics in order to understand the big picture. But, I also admit this can make the graphic difficult to read at times. This is why the book is printed with the highest quality possible (at significantly higher cost than standard quality). I’m pleased the magnifying glass approach is working for you.

While formatting Structured Text can help the readability of a complex Boolean equitation somewhat, I’m confident a contest between experienced ST users and experience LD or CFC users would clearly show the graphical languages to be easier and faster to understand. But that is the beauty of IEC61131-3. You are free to choose whatever language(s) you prefer. I urge my students to use the best language for its purpose, but IEC61131-3 does not force this. You are free to follow the methodology you find best.

Regards,

Gary Pratt
