 A programmable logic controller (PLC) is a rugged computer used in industrial automation. These controllers can automate specific processes, machine functions, and even entire production lines. 

 

How does PLC work?

The PLC receives information from connected sensors or input devices, processes the data, and triggers output according to pre-programmed parameters. Based on the input and output, the PLC can monitor and record runtime data, such as machine productivity or operating temperature, automatic start and stop processes, and generate alarms when the machine fails. Programmable logic controller is a flexible and powerful control solution suitable for almost any application.

 A programmable logic controller (PLC) is a specialized computer used to control machines and process.
It uses a programmable memory to store instructions and specific functions  that include On/Off control, timing, counting.
