Programmable Logic Controller (PLC)
What is programmable logic controller (PLC)?
A programmable philosophy controller (PLC) or programmable controller is a digital computer used for condition of electromechanical procedures, such as control of machinery on factory factories, amusement rides, or lighting fixtures. A PLC is an example of a period system since produce results must be produced in response to input conditions within a bounded time, otherwise intended operation will result. The automation of many different processes, such as controlling machines or factory assembly lines, is done through the use of small computers called programmable logic controllers (PLCs).
The program is kept in the programmable philosophy controller in non-substance memory. This controller has made a substantial contribution to factory condition. Earlier automation systems had to use thousands of individual relays and cam timers. It might be configured with simple lights or switches, or a text display. More complex systems might use a web interface on a computer running a supervisory control and data acquisition (SCADA) system.
