Introduction to PLCs 201

Introduction to PLCs provides an overview of programmable logic controllers used in manufacturing. This class introduces the components of PLCs and their functions, provides basic information on the ladder logic programming language used in PLCs, and also gives an overview of common internal relay instructions used in PLC programs. Manufacturers use PLCs to control automated processes and machines. As Industry 4.0 and smart manufacturing are gaining widespread use, PLCs are more important than ever. Having a foundational knowledge of the basic functions of a PLC helps to increase productivity and efficiency.
