Since the late 1960s, industrial automation has undergone a revolutionary transformation. At the heart of this change lies the Programmable Logic Controller (PLC), a ruggedized digital computer designed to control manufacturing processes, assembly lines, and robotic devices. John W. Webb’s Programmable Logic Controllers: Principles and Applications provides a comprehensive foundation for understanding how PLCs replaced older relay-based control systems and became indispensable in Industry 4.0. This essay examines the basic principles of PLC operation, their key components, and their wide-ranging applications in modern industry.
