The PLC Workbook is designed for engineers and students wishing to learn about programmable logic controllers. It provides an invaluable guide to the practical application of programmable logic controllers in machine and equipment control. Only minimal prior knowledge of machine control, electronics or computers is assumed; the reader is led by means of simple explanations, worked examples and practical exercises from the rudiments of control system components to a reasonable level of PLC competency. After completing the book, the reader should be able to understand the operation of, specify, procure, design, install, operate and de-bug small- to medium-sized PLC installations.Safety should always be a prime consideration when designing the logic for PLC- controlled systems. A further example is now provided. 3.3.3 Use of latch circuit to control motors In order to conform to health and safety guidelines for theanbsp;...
