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 a microprocessor based programming unit used to perform several functions in industrial processes. But it differs in some ways from a computer. Unlike desktop computers, PLCs have multiple inputs and outputs, and are designed for the rugged operation under extreme industrial conditions. PLC is similar to a computer as it has a central processing unit and generates outputs on the basis of some inputs.
