: There is a newer textbook with the same title, Programmable Logic Controllers: Principles and Applications (3rd Edition) , published by ATP Learning in 2021 and authored by Glen A. Mazur and William J. Weindorf. This is an entirely different book from the Webb & Reis edition. Ensure you are searching for the correct authors (Webb and Reis) to avoid confusion.
A fundamental principle detailed in Webb’s book is the cyclic operation of a PLC. Unlike standard computers that run multiple applications concurrently, a PLC executes a strict, continuous three-step loop called the .
By mastering the principles laid out by John W. Webb, aspiring automation professionals gain a rock-solid foundation that allows them to easily adapt to any modern PLC system they encounter in the field.
Solid-state components eliminate the mechanical wear and tear associated with physical relays. : There is a newer textbook with the

Liquid level control, temperature control, and pressure regulation.
Reviewers frequently note it is "clearly written" and "easy-to-understand," making it ideal for maintenance training programs.
The enduring strength of Webb and Reis's work lies in its logically structured, building-block approach to a potentially intimidating subject. The book is organized into eight major sections, each focusing on a key area of PLC knowledge. This careful design allows readers to progress from fundamental concepts to advanced topics without becoming overwhelmed. A detailed outline of its chapters includes: and pressure regulation.
Understanding the foundational concepts outlined in Programmable Logic Controllers: Principles and Applications remains essential for any engineer looking to master these modern, interconnected automation ecosystems.
This comprehensive guide explores the core concepts of Webb’s seminal work, providing an expansive overview of PLC principles, practical applications, and the architectural frameworks that define industrial control systems. 1. Introduction to the PLC Revolution
