Programmable Logic Controllers

A programmable logic controllers (PLC) is a real-time system that is optimized for use in severe environments. Mechatronic devices such as sensors and actuators.

Programmable Logic Controllers, Fifth Edition, continue to be a straight forward, easy-to-read book that presents the principles of PLCs while not tying itself to one vendor or another. Extensive examples and chapter ending problems. Uses of a specific technology. Ladder programming is highlighted with detailed structures, structure lists, and structured text. Methods for fault diagnosis, testing and debugging are also discussed. This edition has been enhanced with I / Os, logic, and protocols and networking.

For the UK public only: This book is fully aligned with BTEC Higher National requirements.


* New material on combinational logic, sequential logic, I / Os, and protocols and networking
* More worked examples throughout with more chapter-ending problems
* As always, the book is a vendor, agnostic allowing for a few concepts
