Lecturer

This course enhances students’ knowledge and understanding on electropneumatics control system used in industrial automation field. It also covers control and integration of electropneumatics components using programmable logic controller (PLC).

Course Synopsis

CO 01: Explain programmable logic controller (PLC) structure and configurations.

CO 02: Design ladder program to control electropneumatic system.

CO 03: Construct control operation system for industrial-based electropneumatics applications using PLC.

CO 04: Demonstrate the role of individual in the team to achieve task completion

Course Syllabus

Assessment MarksQuizzes (3) 3+3+4 = 10%Labs (2) 5+5 = 10%Tests (2) 40+40 = 80%TOTAL 100%

Mark Distribution

Student must attend each class right on time. If 80% attendance is not fulfill, the student maybe failed from the subject

Those who are absent must present an evidence of absences in order to retake any assessment that has been missed during the absence period

Any missed assessment without any evidence of absences will not be tolerate

Any take-home assessment must be passed up before the due date

A deduction of marks according to the situation will be applied to any late assessment submission
