Many published books on PLC lack clear expression of concepts, principles and programming. Finding new control and designing PLC relay logic to control industrial and non-industrial processes are challeging and require to be clearly addressed. The aim of this book is to enable the readers to draw PLC relay logic even for very complex processes. Two advanced PLC programming methods, called the FSM Diagram Method and the Petri Net Method, are discussed with several practical examples. It also provides an overall new perspective on PLC programming. This book is highly useful for PLC professional programmers, researchers and students needing PLC programming as well as those with no prior knowledge of PLC. The book has been written on the assumption that the reader has no prior knowledge of PLC systems and its programming methods. For more details, please visit https://centralwestpublishing.com
