Credit Hours: 3
Lecture Hours: 20

Lecture/Lab Hours:

Lab Hours: 30

Requisites: RET 141

Grading Options:

Special Fee: N/A

Course Description:
The student will understand the 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 and manual methods will be used to program PLC’s.)

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 SLC5000 series and other Programmable Controllers will be used in conjunction with RS Logix 5000 software over network and RS-232 communication protocol.

Course Outcomes:

• Know all the basic components and their functions that are common to all programmable controllers.
• Understand programming basics for Allen Bradley and other types of PLC’s.
• Understand and implement input and output modules.
• Use the computer as a programmer and properly configure communications for “Upload” and “download”.
• Learn all of the basic programming instructions and their application as they relate to industrial controls and the wind energy industry.
• 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.
• Understand and implement motor Controls (two wire, three wire, start/stop etc) related to PLC control.
• Understand and implement analog current loops for controls (4-20mA vs. 0-10vdc).
• Implement contactor and Auxiliary Relay operation.
• Implement proper ground isolation and signal wiring for use with PLC communications.
• Identify related code articles and proper applications.


Outcome Assessment Strategies:

Assessment methods are to be determined by the instructor. Typically, in class exams and quizzes along with homework assignments are used. Lab work is typically assessed by informal and formal lab reports, oral presentation, and possibly a lab exam.

Text & Materials:  (suggested and/or required)

Course Activities & Design:
Using "Hands-On" Programming with a computer, PLC and hardware, the student will design, create, modify and test basic programs for different applications.
