About the Book
Programmable Logic Control (PLC) is one of the most important foundations of modern industrial automation. This book starts with the electrical and control concepts needed by beginners, then moves into PLC architecture, scan cycles, digital and analog I/O, ladder logic, timers, counters, data handling, communication, HMI integration, motion concepts, troubleshooting, commissioning, and advanced design practices.
The emphasis is practical: understand the reason behind each instruction, predict how the controller will behave, and build programs that are readable, diagnosable, safe, and maintainable.
About the Author
Chetan Singh Sendra is the author of this practical PLC learning guide. His goal is to present industrial automation concepts in a clear progression, connecting textbook principles with the kind of reasoning used during commissioning, troubleshooting, maintenance, and production support.
The book is written for electrical and instrumentation students, technicians, engineers, maintenance professionals, automation learners, and working personnel who want to strengthen their PLC fundamentals and move toward advanced applications.
The author's approach is based on a simple principle: a good automation engineer should not only know how to write logic, but should also understand the machine, the electrical signals, the process sequence, the failure modes, and the people who must maintain the system.
