The readers of this industrial automation book will learn the basics and specifics of PLC, SCADA, and DCS. Unlike previous books on PLC, SCADA, and DCS, the book is presented in a distinctive way. ? While not claiming to be completely groundbreaking, this book on Programmable Logic Controllers and Industrial Automation makes an effort to be seen from a different angle. For instance, the books that are often accessible on this subject either solely cover PLC or just mention SCADA and DCS in passing. All subjects are covered in this article. ? At the appropriate points in this book, the conceptual understanding of PLC, SCADA, and DCS is covered. Drawing ladder diagrams for industrial applications based on a conceptual grasp of a subject like programmable logic controllers (PLC) drawing ladder diagrams for industrial applications are also discussed. ? Readers will be able to understand the basics as well as applications of PLC programming, SCADA programming and DCS in this book. The programs and applications of PLC are discussed in deep length. Similarly basics of SCADA and DCS as well as their programming and applications are discussed in the book. ? This PLC and SCADA Book is also written for those students who want to design prototypes. ? The Industrial Automation Book is useful for Engineering students, Engineering colleges and to training Institutes.
