To introduce the basic programming of PLC

To introduce the methods of communication between PLC and other solid-state devices, e.g. variable frequency drive, servo motor drive, etc.

To develop the necessary skills to design and implement a simply servo control system to drive a servo motor.
Learning outcomes 
A. Describe typical motor control methods, including traditional control (hard-wired electromagnetic relay control) and modern control (based on solid-state devices, e.g. a PLC).

B. Demonstrate knowledge of design simple motor control circuits, including both traditional control and modern control based circuits.

C. Demonstrate knowledge and skill of PLC programming

D. Demonstrate knowledge and skill of implementing network communication among PLC and other devices, e.g. lower level drives (variable frequency drives, servo motor drive) and upper level PCs, etc.

E. Demonstrate knowledge and skill of design, integration and testing of a simple servo control system.
Method of teaching and learning 
This module will be delivered through a combination of formal lectures and supervised laboratory sessions. There are totally three pieces of coursework that will be assigned across the semester.
