Programmable Logic Controllers
Author: James A Rehg
Emphasizes the Allen Bradley SLC 500 PLC, covers all three Allen Bradley PLCs (PLC 5, SLC 500, and ControlLogix); as a result, it is the most comprehensive PLC book on the market. Numerous Allen Bradley manuals are included on th enclosed CD to support PLC experiments and problems that demonstrate the use of idustrial reference material. The primary focus of this book is ladder logic programming, but chapters on switches, sensors, output actuators, process control, industrial networks, and three other PLC languages (Function Block Diagrams, Structure Text, and Sequential Function Charts) are also included. Operation and programming for two generations of Allen Bradley PLC softwarel rack/slot-based addressing in the PLC 5 and SLC 500 and tag-based addressing in ControlLogix system. Standard ladder logic building blocks are developed for PLC instructions in Chapters 4 through 11, 13, 15 and 16. Troubleshooting is integrated into each chapter. Descriptions of the five IEC 61131 programming languages with example problems for the four supported in Allen Bradley PLCs. This book describes the technology so that readers can learn PLCs with no previous experience in PLCs or discrete and analog system control.

Designer's Guide to VHDL
Author: Peter J Ashenden
VHDL, the IEEE standard hardware description language for describing digital electronic systems, has recently been revised. This book has become a standard in the industry for learning the features of VHDL and using it to verify hardware designs. This third edition is the first comprehensive book on the market to address the new features of VHDL-2008.
* First comprehensive book on VHDL to incorporate all new features of VHDL-2008, the latest release of the VHDL standard...helps readers get up to speed quickly with new features of the new standard.
* Presents a structured guide to the modeling facilities offered by VHDL...shows how VHDL functions to help design digital systems.
* Includes extensive case studies and source code used to develop testbenches and case study examples..helps readers gain maximum facility with VHDL for design of digital systems.
