A Programmable Logic Controller – PLC, also known as programmable controller, is the name given to a type of computer commonly used in commercial and industrial control applications. PLCs can differ from office computers in the types of tasks that they perform and the hardware and software they require to perform these tasks.
All PLCs monitor inputs and other variable values, make decisions based on a stored program, and control outputs to automate a process or machine.
