Programmable Logic Controllers

Rapid technological advances have made the PLC an important part of many industries, from petrochemicals to food production. At the same time, the study of PLCs has moved into lower academic levels - first year BSc/BEng modules, HNC/D, and Advanced GNVQ. It has been written specifically for current courses, including the BTEC Advanced GNVQ Additional Unit in PLCs, and the City & Guilds 2300 course in Computer Aided Engineering. It also closely matches the new HNC/D unit.



Identify the main design characteristics and internal architecture of PLCs
Describe and identify the characteristics of commonly used input and output devices
Explain the processing of inputs and outputs by PLCs
