needs more real examples

needs more realistic examples to be really useful for home study. other than that it was semi-useful but i went to another book to learn.

Good product, fast delivery

I am a beginner and I've read till Chapter 4 so far. Seems like a good book. It arrived in good condition (new) and the delivery time was as stated.

Didn't work for me

Was looking for more programing help. This is a good review of PLC's but light on programming. Still looking for help in that area.

Tired, dated and moribund

As a software engineer specialising in high-integrity systems and newly working on a safety controller project, I got this book to familiarise myself rapidly with PLCs and how they are used. What struck me immediately is how dated the book is. Almost all of the examples use ladder diagrams at a time when these are increasingly seen as outdated and being replaced by Function Block programs or Sequential Function Charts.Ladder diagrams have the crippling disadvantage that they lack the formal semantics that can be provided for more modern programming formalisms. Thus the only viable forms of verification are simulation and testing. Nowadays this is a long way removed from best practice, especially for safety controllers, where formal verification is now starting to be used. Today anyone programming a safety controller in ladder diagrams is deliberately choosing to ignore better, safer techniques. A PLC textbook that gives almost all of its examples in LDs therefore, IMO, fails to serve its readers well.While the author's prose style is basically clear, his exposition is excruciatingly repetitive, often giving three or four LD examples when it would be much better if it gave equivalent examples in different PLC programming formalisms. The grinding repetition left me wondering what sort of minds (mentalities?) the book was written for.Many diagrams are mislabelled and often the diagrams referred to in one text section actually appear in another. This smacks of desperate, shoddy editing to get out the current fifth edition of a book that is in my view now moribund in its field.

good

just right for the beginner and a refresher in PLC logic and applications as you can apply the information to any make of equipment

Needed to know more about PLC

working my way through this reference book, surprised how much I already knew,but its great to review your knowledge

Good as a basic guide for beginners

Good as a basic guide to the theory for beginners. If you have a background in electronics and understand logic principles this will offer little new insight.
