Programmable Logic Controllers:
Fifth Edition
John W. Webb and Roland A. Reis
Prentice Hall, Upper Saddle River, NJ
The first edition of this textbook appeared in the mid-1980’s.
With the price reductions and technical advances, PLC applications
have mushroomed. Programmable Logic Controllers (PLCs) are now
used in almost every segment of industry where automation is required. The latest PLC models have more functions and
more networking capabilities. In response,
the fifth edition of this textbook addresses the new developments in PLC technology.
This textbook comprises 28 chapters. The topical coverage of these chapters ranges
from an overview of PLCs to plant floor communication and PLC networking. Although ladder logic programming is emphasized
in this textbook, alternative programming languages such as state languages
are briefly described in Chapter 25 of the book. Chapter 20 of this textbook focuses on the control
of a robot using a PLC.
Each chapter of this book starts with learning objectives
and an introduction. Each chapter concludes
with exercises covering topics as they are presented in the chapter.
The sequence of chapters in this textbook is appropriate for a 3 credit-hour
introductory PLC course taught in a two-year or a four-year engineering technology
program.
