Programmable Logic Controllers: Principles and Applications

Programmable Logic Controllers: Principles and Applications covers the fundamentals of installing, programming, and troubleshooting PLC-embedded systems used in industrial control applications. This text/workbook provides a foundation for PLC troubleshooting using software and test instruments while adhering to electrical safety. It also covers the use of discrete and analog input and output device installation, programming, and operation. Large, detailed illustrations of nano-, micro-, and modular PLCs, ladder and programming diagrams, and industrial control cabinets are depicted to support the information presented. Real-world examples allow the learner to follow PLC circuit and system wiring easily and understand the information displayed on PLC screens during the programming process for TECO, Allen-Bradley, and Siemens products.
