Automating with STEP 7 in LAD and FBD: SIMATIC S7-300/400 Programmable Controllers 2nd Edition

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.Franky I am disappointed with the Step 7 products particularly the software. I find it primitive in many ways and much more difficult to use than it needs to be.Programmers should spend their time solving automation problems not struggling with the intracacies and peculiarities of the platform.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.
