A PLC (programmable logic controller) is a kind of common purpose in computer industry which manages the factory automation equipment or processes or operation of industrial in compliance with a saved program for executing particular functions for example timing, sequencing, counting, logic, and arithmetic to control throughout analog or digital inputs and outputs, a variety of types of processes or machines. A characteristic PLC system contains at least one alternative module that carries out the functions of input/output (I/O). When doing operations with the input signals, the PLC develops and produces output signals which are send out through PLC output points to a variety of output devices, for instance relays and actuators, to control the process. The processor and circuitry of input/output in the system PLC are normally designed as divide modules that can be introduced in a chassis and linked together via a general backplane with releasable or permanent electrical connectors.
