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 light
fixtures. PLCs are used in many industries and 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-up
or non-volatile memory. A PLC is an example of a hard real
time system since output results must be produced in
response to input conditions within a limited time,
otherwise unintended operation will result.
