This outstanding book for programmable logic controllers focuses on the theory and operation of PLC systems with an emphasis on program analysis and development. The book is written in easy-to-read and understandable language with many crisp illustrations and many practical examples. It describes the PLC instructions for the Allen-Bradley PLC 5, SLC 500, and Logix processors with an emphasis on the SLC 500 system using numerous figures, tables, and example problems. New to this edition are two column and four-color interior design that improves readability and figure placement and all the chapter questions and problems are listed in one convenient location in Appendix D with page locations for all chapter references in the questions and problems.This book describes the technology so that readers can learn PLCs with no previous experience in PLCs or discrete and analog system control.
