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