A programmable logic controller (PLC) is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes . This type of computer is the most widely used type in the world.
PLCs combine hardware and software to provide highly flexible automation systems for manufacturing plants. In contrast with PC-based systems, the design of PLCs can not be changed by users. The PLC must be programmed to perform desired tasks, and its functions are limited to what programmers tell it to do.
