Frank Petruzella's Programmable Logic Controllers (now in its 6th edition, McGraw Hill, 2023) is the other major player in the PLC textbook market.
Jon Stenerson's Programmable Logic Controllers (with emphasis on Control Logix) is more manufacturer-specific, making it less suitable for schools that use multiple PLC brands but excellent for those standardized on Rockwell Automation.

While John W. Webb’s text heavily emphasizes due to its historical dominance and intuitive design, the International Electrotechnical Commission (IEC) 61131-3 standard defines five major programming languages used in modern PLCs: Webb and Ronald A
For decades, the textbook "Programmable Logic Controllers: Principles and Applications" by John W. Webb and Ronald A. Reis has served as a foundational resource for engineering students and automation technicians. It bridges the gap between theoretical automation concepts and practical, real-world applications. Core Principles of Programmable Logic Controllers
The book provides a comprehensive introduction to Programmable Logic Controllers (PLCs), covering their principles, applications, and programming. PLCs are widely used in industrial control systems to automate and monitor various processes. 4-20mA). Examples include temperature sensors
Increments its accumulated value by one each time the rung makes a false-to-true transition.
Dedicated to fault diagnosis, testing, and debugging. The book covers both hardware troubleshooting (I/O modules, power supplies, field devices) and software debugging (forced inputs/outputs, program monitoring, error logs). Safety issues are also addressed, including proprietary emergency stop relays.
: Handles continuous voltage or current signals (e.g., 0-10V, 4-20mA). Examples include temperature sensors, pressure transducers, and variable speed drives. The Power Supply
