Title: Buyer Beware!
Review: The title of this book, as well as the description, strongly suggest that it covers circuits. Unfortunately, it appears that in this case, the meaning of "circuit" has been hijacked by PLC industry practitioners and assigned a jargon definition that most closely approximates the existing words "Program", "Algorithm", "Procedure", or "Sequence".As you can see, none of these words has much to do with describing:a: the complete path of an electric current including, usually, the source of electric energy.b : an assemblage of electronic elements.which are both meanings of the word "circuit" that can actually be found in a dictionary.If you are a USER of certain families of PLCs, perhaps this book will be of some use. However, at $50, I would strongly suggest just reading the PLC manual.If you intend to DESIGN a PLC, this book will be of absolutely NO USE, whatsoever.
