Course Description

Covers advanced features of Programming controllers including designing, monitoring, troubleshooting and editing techniques with practical hands-on experience. This class can be used toward Continuing Education Units for Oregon State electrical licensing purposes. Audit available.

Addendum to Course Description

This course will be presented by means of lecture/discussion sessions, demonstrations, and heavy emphasis on the "Hands-On" laboratory exercises. *Allen Bradley SLC500 and AB Micrologix 1000 Programmable Controllers will be used in conjunction with RS Logix 500 software over RS-232 communications protocol.

Intended Outcomes for the course

  • Students will demonstrate data table design and layout (assigning I/O)
  • Create, edit, document, and troubleshoot PLC programs for inception to completion.
  • Determine the requirements of the application to be programmed.
  • Demonstrate knowledge of the PLC program flow using subroutines and multiple files.
  • Demonstrate field device inter-connections as they relate to the PLC I/O.
  • 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

Course Activities and Design

Using "Hands-On" Programming with a computer, the student will design, create, modify and test basic programs for different applications. Students will be adding to their library of routines developed in pre-requisite classes.

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, homework, exams, and project performance and quality.
