This book is oriented to the people that work on and troubleshoot PLCs on the factory floor. It is directed at the actual problems and conditions that will be encountered within a realistic setting. The text is designed to present a clear, concise picture of how PLCs operate to the person that wishes to learn more about them.

Programmable Logic Controllers (PLCs) are the backbone of today's Industrial Automation systems. They are more and more often included in Technical curricula nowadays. This basic guide will take you from the very basic concepts, to put PLC code together, all the way up to briefly explore the steps to a successful project! No previous PLC coding experience is needed to begin exploring this fascinating technological world!

Programmable logic controllers (PLCs) are increasing in use, and technicians in all fields must be familiar with the fundamentals of installing, programming, and troubleshooting digital and analog PLCs. Introduction to Programmable Logic Controllers is a text/workbook that provides a solid foundation in PLC theory, installation, programming, operation, and troubleshooting. Many large, detailed drawings of commercial and industrial PLC systems are used to support the information in the textbook. Although hands-on training on industrial equipment is the best training method, teaching the use of digital and analog PLCs is often a challenge because of the high costs of equipment. This training package provides several alternatives to these costs.

What makes a powerful and results-driven Professional Learning Community (PLC)? The answer is collaborative work that expands the emphasis on student learning and leverages individual teacher efficacy into collective teacher efficacy. PLC+: Better Decisions and Greater Impact by Design calls for strong and effective PLCs plus—and that plus is YOU. Until now, the PLC movement has been focused almost exclusively on students and what they were or were not learning. But keeping student learning at the forefront requires that we also recognize the vital role that you play in the equation of teaching and learning. This means that PLCs must take on two additional challenges: maximizing your individual expertise, while harnessing the power of the collaborative expertise you can develop with your peers. PLC+ is grounded in four cross-cutting themes—a focus on equity of access and opportunity, high expectations for all students, a commitment to building individual self-efficacy and the collective efficacy of the professional learning community and effective team activation and facilitation to move from discussion to action. The PLC+ framework supports educators in considering five essential questions as they work together to improve student learning: Where are we going? Where are we now? How do we move learning forward? What did we learn today? Who benefited and who did not benefit? The PLC+ framework leads educators to question practices as well as outcomes. It broadens the focus on student learning to encompass educational equity and teaching efficacy, and, in doing so, it leads educators to plan and implement learning communities that maximize individual expertise while harnessing the power of collaborative efficacy.

A text covering fundamental programmable logic controller (PLC) programming and interfacing methods. Included is a collection of sample ladder logic program segments to perform specific tasks in any PLC program such as flashers, non-standard clocks, timed counters and sequencers, flip flops (RS, D, T, JK), majority decision networks, and one-shots. Topics then move into interfacing methods, discrete sensors, linear transducers, encoders, motor controllers, PID, system safety, and pneumatics. The text can be used in any community college or university-level Engineering Technology PLC course and is also an excellent addition to an engineer's or technician's technical reference library. Readers should have a thorough understanding of fundamental dc and ac circuits, electronic devices (including thyristors), and a knowledge of college algebra and trigonometry.

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.* Thoroughly practical introduction to PLC use and application - not device specific, ensuring relevance to a wide range of courses* New edition expanded with increased coverage of IEC 1131-3, industrial control scenarios and communications - an important aspect of PLC use* Problems included at the end of each chapter, with a complete set of answers given at the back of the book
