Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Use more advanced software to correctly program PLCs.
  • Demonstrate knowledge of the more advanced instructions for PLCs and their uses in the manufacturing facility.
  • Create programs from scratch and design small programs based on electrical schematics or functional descriptions of machine operation.
  • Monitor and edit programs to troubleshoot more advanced industrial control systems.
  • Review and follow NEC and IEEE standards relating to proper wiring code techniques of low voltage controls including:
    • Motor Controls (two-wire, three-wire, start/stop).
    • Analog current loops for controls (4-20 milliamps vs. 0-10 volts DC).
    • Contactor and auxiliary relay operation.
    • Proper ground isolation and signal wiring for use with PLC communications.

Course Activities and Design

This course will start with a quick review of ELT 125 - Basic Programmable Controllers. With “Hands-On” programming using RS Logix on a Windows 2000 computer, the student will design, create, modify and test programs utilizing some of the more advanced instructions.

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.
