Keeping Up with John Rinaldi

A few months ago we mentioned that John was working on a new book about OPC UA “OPC UA - Unified Architecture: The Everyman's Guide to the Most Important Information Technology in Industrial Automation”. I was one of the early reviewers and certainly liked what I saw.
Here is a great review from another reader on

I have followed John Rinaldi's writings for years as a consultant who has a client in the automation engineering industry. I appreciate John's ability to give detailed information in a format that is easily understandable even for the novice. I recommend his books to professionals in the industry on a regular basis. For anyone who is new to OPC UA or would like to get a concise summary I highly recommend getting this book and encourage you to read the chapter on "10 Things to Know About OPC UA." It is straight forward and to the point. John has great wit and a sense of humor you rarely find when reading information on engineering principles. If you have any kind of personality you will find John's commentary on his personal preferences in life entertaining. For those of you who want details, John goes in depth with specifics that will satisfy any veteran in the engineering field. I give "The Everyman's Guide to OPC UA" my highest recommendation.
