What are PLCs and how do they work? PLCs are often defined as miniature industrial computers that contain hardware and software that is used to perform control functions. A PLC consists of two basic sections: the central processing unit (CPU) and the input/output interface system.
A PLC is similar to a computer as it has a central processing unit and generates outputs on the basis of some inputs. The logic or sequence of operation for a process is executed as per a control logic program or software. PLC may be seen as a digital industrial computer control system mainly used for automation of industrial processes, like controlling machinery or factory assembly lines.
