Basic Programmable Logic Controllers (PLC) (CPM-001)

Course Overview

The course is designed to provide the Delegates with basic PLC knowledge and understanding and the practical skills necessary to prepare and analyse basic programmes. Practical activities will provide Delegates with the principles and use of PLC’s used in conjunction with Instrumentation Systems and Plant Control. The course will include a minimum of 50% practical work. The course aims to give Delegates the necessary theoretical training and practical skill development opportunities to be able to undertake basic programming and gain an understanding of the input & output interfaces With plant control equipment.
