A programmable logic controller (PLC) is a type of general purpose industrial computer which controls the operation of industrial or factory automation equipment or processes in accordance with a stored program for implementing specific functions such as logic, sequencing, timing, counting, and arithmetic to control through digital or analog inputs and outputs, various types of machines or processes. A typical PLC system includes at least one option module that performs input/output (I/O) functions. In typical programmable logic controller applications, a variety of input and output (I/O) signals, including analog signals, are processed using addressable I/O modules communicatively coupled to a processor. When performing operations using the input signals, the PLC derives and generates output signals which are transmitted via PLC output points to various output devices, such as actuators and relays, to control the process. The processor and input/output circuitry in PLC system are normally constructed as separate modules that can be inserted in a chassis and connected together through a common backplane using permanent or releasable electrical connectors.
