Looking for a GREAT BOOK to
help you LEARN PLCs?

Well, guess what? You just found it!!!!!

It's been MANY years in the making. Now it's available for all to learn from!

Coming to you from the self-proclaimed "PLC guru" is the hottest new book-
Your Personal PLC Tutor...A Guide to Understanding PLCs.

Phil has, for years, personally taught thousands of people how to program and UNDERSTAND PLCs. His live seminars and tutorial web site have received rave reviews over the years. His work has been seen in top industry trade journals and he's proud to have received numerous awards including TOP 5 controls web site. (Hi, ISA!!)

The book is high-spirited and far from "dry-reading". It's written for the average person and assumes the reader has zero knowledge. It's definitely not like the manuals written for today's general software that sometimes requires a law degree to interpret. (Get the hint Micros**t??)

Finally Learn PLC Programming! No techno-talk used!!

Have you ever wondered how everyone else seems to know PLC programming?

Maybe you work with some PLC programmers... and like what you see.
Maybe you maintain PLCs in your plant but really "don't know how they work... just what they do".
Maybe you're a student taking a class... but the teacher thinks everyone is a "genius".
Maybe you're just thinking about taking a class... but want a jump start to learning.
Or maybe you just want to teach yourself.

Whatever your reason, you've finally found the help you need to get started on your way to PLC programming!

Write your first program! Learn enough information to program most all of the applications you're likely to come across.

What is a PLC? Sounds simple enough... but do you 'really' know what goes on inside the box? Read and learn.

What's the history of the PLC? They've been around for a while. See where they came from and WHY they came about.

What's the proper way to connect a sensor to the input? Find out about NPN and PNP devices.

How do I read a ladder diagram? It's quite simple once we understand the basics. See them here.

Features made for learning FROM experience

  • Numerous illustrations show the topic being discussed.
  • 15 "quiz yourself" sections with the answers included on a separate page immediately following the quizzes. No more going to the back of the book to find 1 word answers.
  • Pages that lay flat. Ever try to read a book and press the pages flat at the same time?? Enough said...
  • Text on 1 side of the page ONLY. The back of each page has been purposely left blank to allow the reader to write notes. I know I write notes when I'm trying to learn...
  • Tough plastic spiral binding to allow it to be thrown into the air upon completion. That's how I celebrate when I completely master a subject...
  • 96 pages of solid text. The text you'll find here at Your Personal PLC Tutor site. Learning text, not boring filler.
  • Knowledge. The knowledge to solve more than 80% of your PLC applications. Enough information is given to get anyone started programming ... immediately.
  • Experience. Learn from somebody who's already made mistakes and learned from them. Phil has taught people of all levels. From Engineering Directors of major corporations to general staff at "mom & pop" shops. From the experienced to the inexperienced. And all types of individuals in between!
  • Cost. How does $39.95 sound?? The price includes priority shipping within the US and Canada. ($44.95 ANYWHERE outside the US and Canada) Oops. Have you already paid $99 for OVER 1000 pages of outdated filler? How about $79 for a book written in the '70's? Was it a $69 book from the '80's that caught your wallet? We know, it was that manufacturers book for $50 that coaxed you. Too bad you didn't get the DETAILED info you NEED... let alone in a non-biased form.
