Course Description

Develops the student's understanding of the complete operation of a variety of programmable controllers. The applications, operations, and programming of PLC's are the areas of study with the main emphasis on programming (computers will be used as programmers). This class can be used towards Continuing Education Units for Oregon State electrical licensing purposes. Audit available.

Intended Outcomes for the course

  • Know all the basic components and their functions that are common to all programmable controllers
  • Understand programming basics.
  • Use the computer as a programmer and properly configure communications for Upload and download.
  • To learn all of the basic programming instructions and their application as they relate to industrial controls and the manufacturing facility.
  • Create programs for different applications, utilizing the basic instructions.
  • Monitor and edit programs.
  • Download test and troubleshoot programs.
  • Review NEC and IEEE standards relating to proper wiring code techniques of low voltage controls including:
    • Motor Controls (two wire, three wire, start/stop etc)
       
    • Analog current loops for controls (4-20mA vs. 0-10vdc)
    • Contactor and Auxiliary Relay operation
    • Proper ground isolation and signal wiring for use with PLC communications
    • Identify related code articles and proper applications

Course Activities and Design

Using "Hands-On" Programming with a computer, the student will design, 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.
