A programmable logic controller (PLC) or programmable
controller is a digital computer used for automation of
electromechanical processes, such as control of machinery
on factory assembly lines, amusement rides, or lighting
fixtures. PLCs are used in many industries and machines,
such as packaging and semiconductor machines. Unlike
general-purpose computers, the PLC is designed for multiple
inputs and output arrangements, extended temperature
ranges, immunity to electrical noise, and resistance to
vibration and impact. Programs to control machine operation
are typically stored in battery-backed or non-volatile
memory. A PLC 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.
