Automating with PROFINET: Industrial Communication Based on Industrial Ethernet

Very satisfied.

There are very few books available on Profinet, outside of the standards groups. I have lots of experience with industrial networking, sw & h/w development and other prerequisites to appreciating this topic. Thus, I thought those things, combined with this book, would hopefully provide enough information get a good start on understanding current devices, and then ultimately providing a good base on which to develop a compatible device. As a bonus, I thought that I might learn about a wider array of other profinet-compatible devices.Unfortunately for me, the coverage was at once too broad and too focused. For instance, the book provides information on high-level topics in networking, ethernet, I/O and so forth, but without a lot of detail. This overview may be helpful to some readers, but seemed to me to be review for those in deep enough to be tackling this sort of work.At the same time, Siemens specific topics - primarily programming - are covered in extreme depth. If that's what you're after, this might be just what the doctor ordered.Bottom line for me: I know that "Siemens" is clearly printed on the cover, so I expected a bias. Where it runs off the rails is the PROFINET portion of the title. I feel it was disingenuous to make that big and bold, when so little of the book - hardly any - describes the protocol itself. This is a technical book, covering a specific topic, and I expect that to be addressed directly, before diving into ancillary topic, however useful they may be.The book is beautifully typeset, and effective images are used throughout. It appears to be well edited too. It's very readable - great. Again, in my view, the only serious issue is the contents are not what the cover and description claims them to be. For that reason, I just have to give 4 stars instead of 5.
