This course is designed to present the origin and evolution of programmable logic controllers. Special emphasis is placed on the fundamentals of Relay ladder Logic (RRL) programming methods and the analysis of circuit operations as well as various applications of Programmable Logic Controllers (PLC’s) used in modern industrial applications. Students will receive the necessary hands on experience in lab to be able to design, program, construct, troubleshoot, and perform preventive maintenance of all components of a PLC controlled process. Students will be evaluated on troubleshooting techniques, terminations of input and output devices, and the proper maintenance of at least two different types of PLC Manufactures.
