Dry, many typos, no publisher noted
May 25, 2019
I did not expect an easy read for this type of book but the writing was overly dry, written by a programmer, not a book writer. There are many typos which are very distracting to a detailed person (who would be the type of person reading this book.) The book does not note any publisher nor is there any contact info. It is therefor not likely to ever get the thorough update that a technical book deserves. My book is very marked up with typos but every reader will suffer through them on their own. :-(
The book seriously deserves an index but alas, it has none. If you want to search for all the types of Timers that Step 7 has, you want to look in the index, see all the types, and know on what page each type is explained. Indexes are soooo easy to do with today's writing programs.
While the title of the book alludes to a very specific audience who are interested in Siemens Step 7, the book instead seeks to want admiration for it number of pages. With many, many pages detailing programming instructions that are widely used in every PLC environment (Return, Jump, Label, etc), the user is forced to search out the specific issues of the Siemens product. The title states 'Practical Approach'! Nope. This book could be great if it really spoke to the product it was declaring itself to be and left all of the universal PLC stuff to other 'beginner' books that abound and will likely have already been read before someone buys this book.
I end this mini review by sharing one of the non-edited statements in the book. Pg 85 "If forces are active, the Maintenance LED will blink (See Figure 3-58). Do not look to Figure 3-58 and expect to see the LED blinking. ;-) But you will find that the colour screenshots have been converted to grey scale and you won't really be able to see that the Maintenance LED is lit.
BTW, the opportunity for edits to the book are possible as there are not hundreds or thousands of the books sitting on the shelf from the last printing. Each book is individually printed when ordered! Ain't technology sweet?!
