This book could deal with a general overview of some supposed PLC controller. Author has had an opportunity to look over plenty of books published up till now, and this approach is not the most suitable to the purposes of this book in his opinion. Idea of this book is to work through one specific PLC controller where someone can get a real feeling on this subject and its weight. Our desire was to write a book based on whose reading you can earn some money. After all, money is the end goal of every business!
