A programmable logic controller (PLC), or programmable controller is an industrial digital computer which has been ruggedised and adapted for the control of manufacturing processes, such as assembly lines, or robotic devices, or any activity that requires high reliability control and ease of programming and process fault diagnosis.
The CPU-Central Processing Unit. How PLCs work is down to the CPU, the CPU is the PLC part which is the brain of the whole PLC.
