Code: PLC

Duration: 40 Hours


Programmable Logic Controller (PLC) is the heart of all automated control systems. With a controlled application program in running, the PLC monitors the input status of the process and controls the output status based on a pre-determined requirement. The PLC is used to control a simple and repetitive task. It can also be connected to other controllers to control a more complex task.

This module is developed to enable learners to acquire knowledge and skills in performing Programmable Logic Controller that includes selecting appropriate control devices, integrating of logic controls, writing software program for the automated machines.
