This is the introduction to PLCs for which baffled students, technicians and managers have been waiting. In this straightforward, easy-to-read guide, Bill Bolton has kept the jargon to a minimum, considered all the programming methods in the standard IEC 1131-3 - in particular ladder programming, and presented the subject in a way that is not device specific to ensure maximum applicability to courses in electronics and control systems.Now in its fourth edition, this best-selling text has been expanded with increased coverage of industrial systems and PLCs and more consideration has been given to IEC 1131-3 and all the programming methods in the standard. The new edition brings the book fully up to date with the current developments in PLCs, describing new and important applications such as PLC use in communications (e.g. Ethernet – an extremely popular system), and safety – in particular proprietary emergency stop relays (now appearing in practically every PLC based system).The coverage of commonly used PLCs has been increased, including the ever popular Allen Bradley PLCs, making this book an essential source of information both for professionals wishing to update their knowledge, as well as students who require a straight forward introduction to this area of control engineering.Having read this book, readers will be able to:* Identify the main design characteristics and internal architecture of PLCs* Describe and identify the characteristics of commonly used input and output devices* Explain the processing of inputs and outputs of PLCs* Describe communication links involved with control systems* Develop ladder programs for the logic functions AND, OR, NOT, NAND, NOT and XOR* Develop functional block, instruction list, structured text and sequential function chart programs* Develop programs using internal relays, timers, counters, shift registers, sequencers and data handling* Identify safety issues with PLC systems* Identify methods used for fault diagnosis, testing and debugging programsFully matched to the requirements of BTEC Higher Nationals, students are able to check their learning and understanding as they work through the text using the Problems section at the end of each chapter. Complete answers are provided in the back of the book.
