Author: John W. Webb (with Ronald A. Reis in later editions) Publisher: Pearson / Prentice Hall Subject: Industrial Automation, Control Systems, and PLC Programming Hardware Agnostic: It teaches ladder logic

3. Manufacturer-Neutral but Example-Rich

The PDF uses generic instruction names (e.g., "Examine if Closed" rather than "XIC"), making it compatible with Allen-Bradley, Siemens (with slight translation), and Modicon. However, Webb frequently references the Allen-Bradley PLC-5 and SLC 500 as de facto examples, reflecting the US market of the 1990s–2000s.

Key Features of the Webb & Reis Approach:

• Hardware Agnostic: It teaches ladder logic, I/O systems, and programming structures that apply across any platform.
• Practical Troubleshooting: Extensive chapters on fault diagnosis and maintenance.
• Progressive Difficulty: Moves from basic relay replacement to advanced PID (Proportional-Integral-Derivative) control.

For anyone searching for the PDF version, the goal is usually immediate access to these core concepts without the weight of a physical textbook.

Who Is This Book For?

• Trade school or community college students – Especially if your lab uses older PLCs (MicroLogix, SLC-500, TI505).
• Maintenance technicians moving from relays to PLCs.
• Self-learners who want theory before touching a software IDE.
