TEACHING PLC IN AUTOMATION --A Case Study Dr. George Yang, Assistant Professor And Dr. Yona Rasis, Assistant Professor Department of Engineering Technology Missouri Western State College 4525 Downs Drive St. Joseph, MO 64507

Abstract Programmable logic controllers, PLCs, have become the industry standard, replacing the hard-wired electromechanical devices, in controlling process machines and driving the equipment of manufacturing. Varying in size and sophistication, these electronic devices are now produced by over 50 manufacturers. In our 2 and 4 credit- hours courses for manufacturing and electronic engineering technology students, relay circuits, fundamentals of sensors, and electrical controls are explained first. Then, the PLCs, from hardware structures, installation, wiring, to ladder logic programming are elucidated. Experience in teaching two different groups of students with different academic background and preparation are presented. Approaches taken in each class are discussed.

Introduction Manufacturing systems were controlled by electromechanical devices, such as relays, solenoid valves, and actuators, before the digital electronics came on the scene. Nearly all controllers were permanently hard-wired, making changes difficult and expensive. Programmable logic controllers, PLCs, have dramatically altered this picture since their initial applications in 1960s. Because of their functionality and versatility, PLCs are playing ever-popular and critical roles in modern manufacturing systems.

Missouri Western State College is a public, state supported institution providing a blend of traditional liberal arts and sciences and career-oriented degree programs. Professional education programs such as teacher education, nursing, engineering technology, and business have played an important role at Missouri Western for many years and have come to be seen as an area of strength for Missouri Western throughout the northwest Missouri region. The college has chosen to retain its open access policy while continuing its commitment to pursue academic excellence and quality teaching.
