Introduction to Programmable Logic Controllers

Book excerpt: 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.
