Let’s take a classic Webb project from the "upd" version and modernize it.
Problem: Design a PLC program for a three-story elevator. Webb’s Approach:
Modern Upgrade: Use the same principles but add an HMI page for fault diagnostics—exactly as the updated appendix suggests. Let’s take a classic Webb project from the
The book is structured to guide a student or professional from basic concepts to advanced system design. The authors utilize a "building block" approach:
Programmable Logic Controllers: Principles and Applications (often found in its various editions, such as the 5th Edition) by John W. Webb and Ronald A. Reis is a seminal textbook in the field of industrial automation. It serves as a bridge between theoretical electrical engineering and practical technician-level application. Modern Upgrade: Use the same principles but add
The text is renowned for its accessible writing style, comprehensive coverage of the Allen-Bradley PLC architecture (specifically the SLC 500 and ControlLogix families), and its heavy emphasis on the IEC 61131-3 programming standard. This paper provides an in-depth analysis of the book's pedagogical structure, core technical principles, and its relevance in modern industrial applications.
One of the book's strongest contributions to the field is its adherence to the IEC 61131-3 standard, which defines programming languages for PLCs. The text covers: here is the smart path:
I know the budget is tight (PLC textbooks are notoriously expensive). If you need the information but can't afford the $100+ price tag, here is the smart path:
