Code: PLC-1
Duration: 18 Hours
Synopsis:
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 is a fundamental PLC training course designed for learners with no prior PLC programming experience to create a PLC program.
Course Objective:
On completion of this course, learners will be able to write programs for simple PLC operations.
Course Outline:
