This informative book provides a comprehensive theoretical and practical look at all aspects of PLCs and their associated devices and systems.

Practical and up-to-date, TECHNICIAN'S GUIDE TO PROGRAMMABLE CONTROLLERS, 6E, International Edition provides readers with the most comprehensive introduction to PLCs available on the market today. Theory, hardware, instructions, programming, installation, startup, and troubleshooting are discussed in detail in a way that is easy to understand and apply. In addition, supplementary programming examples utilizing the PLC instructions in the book give readers a better understanding of the various instructions and how they can be combined to create simple yet effective control logic solutions for today's world.

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.

A programmable logic controllers (PLC) is a real-time system optimized for use in severe conditions such as high/low temperatures or an environment with excessive electrical noise. This control technology is designed to have multiple interfaces (I/Os) to connect and control multiple mechatronic devices such as sensors and actuators. Programmable Logic Controllers, Fifth Edition, continues 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 utilize several popular PLCs currently on the market highlighting understanding of fundamentals that can be used no matter the specific technology. Ladder programming is highlighted throughout with detailed coverage of design characteristics, development of functional blocks, instruction lists, and structured text. Methods for fault diagnosis, testing and debugging are also discussed. This edition has been enhanced with new material on I/Os, logic, and protocols and networking. For the UK audience 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 vendor agnostic allowing for general concepts and fundamentals to be taught and applied to several controllers

Andrew Parr's Programmable Controllers provides a thoroughly practical introduction to the use of PLCs in industry, covering programming techniques alongside systems-level design issues. In the third edition a masterclass series of real-world case studies have been added to illustrate typical engineering challenges - and model solutions. New material also includes the new IEC-61508 functional safety standard, use of Windows-based software on programming terminals, an expanded section on Scada, and extended coverage of networks and fieldbus. Andrew Parr works at ASW Sheerness Steel where the plant control is based on approximately sixty programmable controllers. - The practical guide to PLC applications for engineers and technicians - Systems-level design and control covered alongside programming techniques - Coverage matched to introductory college programs

The third edition of Fundamentals of Programmable Logic Controllers, Sensors, and Communications retains the previous edition¿s practical approach, easy-to-read writing style, and coverage of various types of industrial controllers while reflecting leading-edge technology. Since the programmable logic controller has become an invaluable tool in American industry, it responds to the substantial need for trained personnel who can program and integrate these devices. Covers new and emerging technologies and techniques—IEC 61131 programming; Industrial automation controllers; ControlLogix; Embedded controllers; Supervisory control and data acquisition; Fuzzy logic; Step, stage, and state logic programming. Features process control and instrumentation—Process Control, PLC Addressing, PLC Wiring, and Robotics. For trained personnel using programmable logic control devices.

Useful for an undergraduate-level course on PLCs or Electronic Controls, this book provides coverage on programmable logic controllers. It discusses applications for each PLC function, and includes an array of examples and problems that help students achieve an understanding of PLCs.
