| PLC Programming for Industrial Automation |
I have been teaching PLC programming for fifteen years and the question that I hear most often from students is “Can you recommend a book on this?” In response I have trotted out the titles of various standard text books but I have never come across a book that really develops the skill of PLC programming instead of telling the reader what PLCs are all about. I have finally decided to fill this gap in the market myself.
“What sort of PLCs do you use?” is another popular question. It implies that familiarity with one make and model of PLC will leave the programmer struggling when asked to use a different type. I deliberately teach a generic style of programming that allows the learner to switch between types of PLC as easily as between different makes of electronic calculator. Every skill needs practice however and my thanks are due to TriLogi for permission to use their excellent PLC simulator software throughout this book. The students can load the software onto a computer and practice the examples and exercises provided.
