Before the advent of PLCs, industrial processes were controlled by massive banks of hard-wired relays. These systems were cumbersome, difficult to troubleshoot, and required complete rewiring whenever a process change was needed. John W. Webb’s text begins by tracing the transition from these rigid relay-logic systems to the flexible, software-based environment of the PLC. By understanding this history, readers appreciate the efficiency and modularity that PLCs bring to the factory floor. Core Principles of PLC Technology

The book is famous for its clear explanation of Ladder Diagram (LD) programming. By mimicking the look of electrical schematics, it allows those with a background in electrical wiring to transition smoothly into programming.
