Reviews

Anyone involved with exploring the world of Step7 would do well with this book.
I have been involved with PLC technology since 1979 and even today there are too few available reference manuals. (Amazon)
...
If you program with Step 7 or plan to, this book will save you a lot of headaches since little in Step 7 is as intuitive as Allen Bradley or Modicon.
