Allen-Bradley PLCs: An Emphasis on Design and Application
Second Edition
by
Kelvin T. Erickson
Missouri University of Science and Technology

This book presents an introductory treatment of Allen-Bradley programmable logic controllers (PLCs) with an emphasis on program design. This text stresses an organized approach to developing PLC programs - "Given a set of operational specifications, how does one develop the PLC program?" This book develops the design process: the tasks involved, breaking the program into manageable pieces, standard code for the various parts, and handling the sequential parts of the problem. Throughout, the book contains example problems demonstrating good design practice and culminates in a full-length case study. There are more than 150 homework problems and the text is illustrated with about 600 figures. Due to its popularity, ladder logic is employed in the text. This language is covered for Allen-Bradley ControlLogix, CompactLogix, Micro800, MicroLogix, and SLC-500 processors.

Changes for Second Edition


The second edition primarily adds the Micro800 controller, but there are other changes:
  • Information on input and output buffering has been added to Chapter 2
  • Addressing for 5069- and 5094-series I/O modules has been added to Chapter 3.
  • Chapter 11 problems have been deleted, since most currently available analog input modules perform the conversion. The thermocouple and RTD conversion examples are retained in case the reader encounters an older system that performs the conversion in the PLC program.
  • Chapter 13 has extensive updates to reflect recent developments in operator interfaces, called "High Performance HMI."
  • The section on ControlLogix simulation in Chapter 15 has been revised to utilize I/O module inhibits to disable the I/O scan.
  • The appearance of the ControlLogix blocks has been updated to match the changes effective with Studio 5000 version 31.
  • All of the chapter problems have been replaced with new problems
Though obsolete, the MicroLogix and SLC-500 processors have been retained.
