A common critique of the Webb & Reis text is that it was written before the explosion of Industry 4.0. However, the principles remain unshaken.
One PDF snippet that circulates heavily online is Webb’s – a step-by-step guide to checking power supply, CPU fault LEDs, backplane connections, and I/O fuse status.
Few textbooks have left as lasting a mark on industrial automation education as Programmable Logic Controllers: Principles and Applications by John W. Webb and Ronald A. Reis. For decades, this book has served as the go-to resource for students, technicians, and engineers stepping into the world of programmable logic controllers (PLCs). Whether you are searching for a PDF copy, exploring its contents, or simply curious about its legacy, this article covers everything you need to know.
A: Yes. Level I of the CCST exam heavily relies on the fundamentals taught in Webb’s Chapters 1 through 8. A common critique of the Webb & Reis
