5.0 out of 5 stars Interesting and Unique treatment of PLCs
Although some of the material (such as discussion of the A/B PLC-2) is somewhat dated, the fundamentals of PLCs is covered so well that it more than makes up for this short-coming.

Its a well-written book by an author who obviously has a lot of experience in the field. I particularly liked the chapter on sequencers and found the introductory chapters to be very...

2.0 out of 5 stars Good basic text, but dated material
I've used Simpson to teach PLC basic at a community college in Vancouver, WA. It is a good solid text that covers much of the basics of PLCs and PLC applications.

2.0 out of 5 stars Good basic text, but dated material, February 26, 1999
This review is from: Programmable Logic Controllers (Paperback)
I've used Simpson to teach PLC basic at a community college in Vancouver, WA. It is a good solid text that covers much of the basics of PLCs and PLC applications. The book does not focus on one PLC brand, but uses programming examples from Modicon, Allen-Bradley and Texas Instruments controllers. Simpson has some good programming examples, but could use more.

There are two issues I have with the text. The most important is that the information is dated. For example the Allen-Bradey information is all relevant to the PLC-2, a product that was obsoleted not long after the publication date, if not before. (Very confusing for my students who are trying to learn AB SLC-500 addressing which is completely different.) Second, there is very little about I/O types (AC, DC, triac, FET, etc.) and some of the important characteristics of each. If this book were revised with an eye to current industry practices, I would give it a much stronger recomendation.
