Programmable Logic Controller

Basics

• Often abbreviated as PLC
• A Digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly lines, amusement rides, or light fixtures
• 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.
