Programmable Logic Controlling System is a digital computer that is used for automation of electromechanical processes. The PLC is designed for multiple inputs and output arrangements, extended temperature ranges, immunity to electrical noise and resistance to vibration and impact. The PLC stores the programs to control machine in a battery backed or non – volatile memory. Programmable Logic Controlling System is an example of a real time system since output results must be produced in response to input conditions within a bounded time, otherwise unintended operation will result.
