Week 14: Programmable Logic Controllers: (Introduction to PLCs, Advantages of PLCs)

PLC

A programmable logic controller, commonly known as PLC is a specialized computer mainly used for automation in various
industries. It is used in place of automation of a car manufacturing company where robotic arms are used, places where motors needs
to be driven on reception of a command signal, in electrical power system for the operation of circuit breaker, etc. PLCs are
programmable hence a single unit can be used for different kind of operations based on where it is used making it a versatile device.
The major advantage of a PLC over the conventional controllers its robust nature. It has high fidelity in most dynamic environments.
PLC is reluctant to noise from the peripherals and hence is a reliable device for automation where accuracy and correctness is
prominent. Another major advantage of a PLC is its ability to handle multiple input and output ports which processes analog as well as
digital signals
