UA19 Selection and Using Programmable Controllers

Pearson BTEC Level 3 Engineering – UA19 Selection and Using Programmable Controllers

This unit can be studied as a standalone TECOL unit in Engineering, or as part of an Edexcel accredited BTEC Level 3 qualification in Engineering.  

Aim and purpose

This unit will give learners an understanding of the use and applications of programmable logic controllers(PLCs), the hardware and software that makes up a PLC and the interaction needed between the component parts.

Unit introduction

This unit will consider programmable logic controllers (PLCs), control devices which aid the automation

of these processes. The capabilities of PLCs have developed over the years, with performance, reliability and operational resilience being key attributes to their continued success. In order to achieve automated monitoring and control, these devices can be used on their own or in conjunction with others through communication systems/links, which are themselves becoming more versatile.

The unit will introduce learners to the use and applications of PLCs, the hardware and software that makes up a PLC and the interaction needed between the component parts. Learners will develop their ability to use programming techniques to produce programs for modern PLCs. They will also gain an understanding of the different types of communication media used to link larger numbers of PLCs together, the networking architecture used and the associated standards and protocols.

On completion of this unit a learner should:

  1. Understand the selection, hardware and software requirements of a programmable controller

  2. Be able to use programming techniques to produce a program for a modern programmable controller

  3. Understand complex programmable controller applications

  4. Understand data communications media and networks used with modern programmable controllers.
