Programmable Logic Controllers provides the student with a general working knowledge of the various PLC brands and models. Programming concepts applicable to virtually all controllers are discussed, and practical programming problems are presented throughout the text. A basic understanding of AC/DC circuits, electronic devices (including thyristors), basic logic gates, flip-flops, Boolean algebra, and college algebra and trigonometry is a prerequisite. The PLC simulation CD that accompanies the text provides hands-on programming experience.https://digitalcommons.odu.edu/engtech_books/1002/thumbnail.jp
