Intended Outcomes for the course
Upon completion of the course students should be able to:
Apply a basic understanding of the components, functions, and programming common to all programmable logic controllers (PLC)
Use a computer to do basic programming of a PLC and properly configure communications for upload and download.
Apply basic programming instructions in a facilities maintenance, manufacturing, industrial, or processing work environment.
Create, monitor, edit, and troubleshoot basic programs for PLCs.
Apply basic National Electrical Codes (NEC) and Institute of Electrical and Electronic Engineers (IEEE) standards to low voltage controls including two-wire, three-wire, and start/stop motor controls; to analog current loops (4-20 milliamp vs. 0-10 Volts DC ); and to contactors and auxiliary relays .
Course Activities and Design
Using "Hands-On" Programming with a computer. The student will create, modify and test basic programs for different applications.
Outcome Assessment Strategies
Procedures will be discussed at the first class session and the instructor's grading policy will be referenced on the class syllabus. Assessment will be based on attendance, participation, personal improvement, homework, quizzes, and the final examination.
