Programmable Logic Controllers: Principles and Applications by John W. Webb and Ronald A. Reis

Programmable Logic Controllers: Principles and Applications by John W. Webb and Ronald A. Reis

Programmable logic controllers (PLCs) are electronic devices that control industrial processes and machines. They are widely used in manufacturing, process control, and automated testing. PLCs can be programmed using various languages, such as ladder logic, function blocks, sequential function charts, and structured text. PLCs can communicate with other devices using different protocols, such as Ethernet, Modbus, Profibus, and CAN.

Programmable Logic Controllers Principles And Applications By John W Webb Pdf Free 16

Programmable Logic Controllers: Principles and Applications is a book that provides both fundamental and advanced coverage on PLCs. It was written by John W. Webb and Ronald A. Reis, who are both professors of electrical engineering at Clemson University. The book was first published in 1994 and has been updated several times since then. The latest edition was published in 2003 by Prentice Hall.

The book covers the following topics:

  • The history and evolution of PLCs

  • The hardware components and architecture of PLCs

  • The programming languages and methods for PLCs

  • The input/output devices and interfacing techniques for PLCs

  • The troubleshooting and maintenance of PLCs

  • The applications and examples of PLCs in various industries

  • The trends and future developments of PLCs

The book is intended for students, technicians, engineers, and managers who want to learn about PLCs or improve their skills in PLC design and programming. The book is also suitable for self-study or as a reference for professionals. The book includes numerous industry examples, exercises, review questions, and case studies to illustrate the concepts and applications of PLCs.

Programmable Logic Controllers: Principles and Applications is available in PDF format for free download from various online sources[^1^] [^2^] [^3^]. However, the quality and legality of these sources may vary. The book can also be purchased from online retailers or bookstores.PLC Applications and Examples

PLCs have a wide range of applications and examples in various fields and industries. Some of the common PLC applications and examples are:

Industrial Applications of PLC

PLCs are used to control and monitor industrial processes and machines, such as:

  • Transportation systems, such as conveyor belts, escalators, and elevators

  • Packing and labeling systems in food and beverage, pharmaceutical, and other industries

  • Automatic bottle or liquid filling systems

  • Industrial crane control systems for operation of overhead traveling cranes

  • Glass, paper, cement, and other manufacturing industries for production and data recording

  • Automatic drainage water pump monitoring and controlling systems

  • Time and count-based control systems for industrial machines

  • Temperature or humidity controllers using sensors input to the PLC system

  • Fault detection and protection of industrial machines, such as induction motors

  • Wind turbine systems for maximum efficiency, data recording, and safety purposes

  • Energy management systems, such as boiler, ball milling, coal kiln, shaft kiln, etc.

  • Oil and gas industries for controlling the purging procedure

Power Station Applications of PLC

PLCs are used to perform operation, maintenance, and analysis functions in the power plants and the smart grid system, such as:

  • Smart grid system to monitor and detect fault conditions

  • Power generation, transmission, and distribution system

  • Power substation auto assembly line system
