• 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

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.

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.
