Programmable Logic Controllers: Principles and Applications by John W. Webb - A Comprehensive Guide

2. Fundamentals (Chapters 1–3)

What is a PLC?

• A ruggedized industrial digital computer designed for real-time control of manufacturing processes, assembly lines, robotic devices, or any activity requiring high reliability and ease of programming.
• Key differences from PC: No keyboard/mouse as primary input; uses input modules (sensors, switches) and output modules (actuators, motors); real-time deterministic scan cycle.

Applications Across Industries

PLCs excel in environments requiring reliability, ruggedness, and ease of modification. Webb and Reis detail applications such as: you must layer these skills with:
