The best comments I can make about this book can be taken from the book itself:From the Preface: The [OPC UA] specification primarily defines how to do things and to a lesser extent explains why it was designed that way. This is the way specifications have to be written to be widely applied by many developers and to guarantee interoperability between different applications. As a result, the OPC UA specification is hard to read for someone new to OPC UA. This is also true for other specifications such as SQL or UML. With this book, we want to fill this gap and provide an easy to understand introduction to OPC UA. We will not provide the same detail as the specification, but rather introduce and explain the main concepts of OPC UA.--> The book has delivered on this.From the Acknowledgments: Thanks to [...] the native speakers who greatly improved our English.--> The grammar is annoying at times, especially when you need to read a sentence twice to understand it.
If I need this book, it is because I don't understand OPC architecture. Unfortunately, the author writes in such an obtuse manner that you need to understand it already to understand what he is talking about. Anybody know of a "for Dummies" equivalent?
The authors participated in the elaboration of standards and present it with clarity and substance. Essential for implementation of the standard.
Go over the concepts, start kind of slow and it is a dry reading, so get some coffee and a quiet place.
This book was written by technically qualified authors who have been involved in developing the OPC UA specification, so I'm assuming the information it contains is correct. Unfortunately I think this is the only thing I can say in it's favour.The book only covers the concepts. There are no details, in fact there are insufficient details to even be able to troubleshoot a UA system effectively, let alone implement one. Of course this book is intended as a handbook, not a detailed spec, so to a limited extent that is acceptable.On the other hand it is written and laid out as a specification, and is just as unreadable.The official OPC UA specifications are not generally available and I am not able to see them. However I can't help get the feeling that if I could see them there would be a haunting familiarity. I get the impression that the book has been written by taking the specifications and changing any detailed information into vague and general statements. Then extra info, such as historical info or other background stuff,has been thrown in for good measure.The book appears to list the concepts in a linear manner, rather than explain the big issue in a drill down manner, as a handbook should do.The quality of the English is understandable, but very poor. This is really a reflection on the translation rather than the original text, as I believe the original was German.I find it difficult to recommend this book, and the high price tag adds insult to injury. On the other hand there does not appear to be any alternatives, and perhaps the real problem is that there is simply insufficient market to justify a book written by a professional author.
I regard this book as the first one you should read if you are new to OPC UA. It explains the concepts good and is understandable if you are a technical IT person (bear in mind that it is intended for IT specialists). It lays the concepts well and has a few examples that make things alot easyer. For the information it delivers it is well priced.Do not be frightened if you are at the middle of the book and things are still a little blurry, as things will start to clear out. Maybe the only thing that is a little troublesom is the organization of the chapters. The author shows a little bit of architecture in the beginning but jumps to modelling and services/transport. Only at the last quarter of the book more architecture is explained, I think that he should have kept more architecture in the beginning to make a more fluent tranition from general specifications to detail.
