Course Description

Covers the highly advanced features of programmable logical controllers (PLC). Includes advanced design, monitoring, troubleshooting, and editing techniques coupled with practical, hands-on experience. Focuses on the use of Allen Bradley Micro-Logic 1100 Series PLCs using a PC for programming. Audit available.

Intended Outcomes for the course

Upon completion of the course students should be able to

  • Demonstrate and complete data table design and layout (assigning I/O).
  • Create, edit, document, and troubleshoot highly advanced PLC programs from inception to completion.
  • Determine the requirements of the advanced 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.
  • Interpret 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

Using "Hands-On" Programming with a computer, the student will design, create, modify and test advanced  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.
