II.        PREREQUISITE:      EET 251, and EET 252

 

III.       CREDIT HOURS:     Three (3) semester hours.

 

IV.       TEXTBOOK:

 

Rabiee, M., (2000). Allen-Bardley SLC500TM Programmable Logic Controller, Lincolnshire,

            IL. Energy Concepts Incorporated (ECI).

 

 

V.        COURSE OBJECTIVES:  Students successfully completing this course should be able to:

 

A.        List the essential components found in a Programmable Logic Controller (PLC) system.

 

B.        Read and use manufacturer specifications in the selection of PLCs for specific application.

 

C.        Describe the hardware characteristics of the SLC 500 series, Allen-Bradley family of Programmable Logic Controllers.

 

D.        Read and understand the specifications for the PLC Input/Output ports.

 

E.         Discuss the use of memory and I/O mapping in the SLC 500 Programmable Logic Controller system.

 

F.         Explain the difference between contacts, relays, and switches in the PLC system.

 

G.        Explain the difference between the Normally Open (NO), and the Normally Closed (NC) contacts, and switches.  Utilize the (NO) and the (NC) contacts and switches in an application.  

 

H.        Discuss the Temperature switch, the Limit switch, the Level switch, the Pressure switch, the Flow meter switch, and other Industrial Control switches.

 

            I.          Discuss the timer relays, the On-Delay timer contact, the Off-Delay timer contact, the Counter relays, and the counter contacts.

 

J.         Discuss the use of Solenoid in the Industry.

 

K.        Write, debug, and run PLC programs to implement the use of aforementioned relays, contacts, switches, timers, and counters.

 

L.         Discuss the use of PLC Programming commands SKIP, MASTER CONTROL RELAY (MCR), JUMP (JP), and JUMP SUBROUTINE (JSR).

 

M.       Discuss the DATA MOVE.

 

N.        Discuss Trouble shooting, and Servicing - Procedures and Techniques for the PLC systems.

 VII.    COURSE ACTIVITIES:       In addition to tests, there will be written assignments in the class relating to the course content.  Students are also expected to attend each lecture, attend each laboratory session and complete all reading and laboratory assignments on time.

 

 

VIII.    EVALUATION PROCEDURES:  Students will be evaluated as follows:

 

A.              Four one hour exams                                                                30%

B.              Final Exam  (Comprehensive)                                                 20% 

C.              Lab Assignments, Quizzes, and written assignments                   40%

D.              Attendance and class participation                                             10%

 

IX.       ATTENDANCE POLICY:     Students are expected to attend each class session to derive full benefits from the course.  If you must miss a class, let me know that you will be absent by calling my office or by email.  Each missed class will result in a reduction of ~ 3.33 points from the attendance grade.  Seven (7) absences or more will result in a zero (0) for the class attendance and participation portion of the grade. Also, three(3) tardies will count as one (1 ) absence.

 

X.        POLICY ON LATE ASSIGNMENTS:        Assignments are due by the end of the class session assigned. Any assignments turned in late will receive a lower grade (10 points for each day late). Assignments will not be accepted if more than 3 days late.

 

XI.       FORMAT FOR ALL ASSIGNMENTS:

A.     Name in upper right corner of each page

B.     Multi-page assignments to be stapled in the upper left corner

C.     Smooth edge standard (8.5” x 11”) paper only

D.     Use only one side of the paper

E.      Neatness counts “ALL papers are to be typed”!

XII.     GRADE DISTRIBUTION:  Grades will be distributed according to the following:

                        A.............. 100 – 94

                        A-............. 93.4 - 89.5

                        B+............ 89.4 – 86.5

                        B.............. 86.4 – 82.5

                        B-............. 82.4 – 79.5

                        C+............ 79.4 – 76.5

                        C.............. 76.4 – 72.5

                        C-............. 72.4 – 69.5

                        D+............ 69.4 – 66.5

                        D.............. 66.4 – 62.5

                        D-............. 62.4 – 59.5

                        F............... 59.4 – 0
