Prentice Hall, Upper Saddle River, NJ

The first edition of this textbook appeared in the mid-1980ís.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.
