The main purpose of a
Programmable Logic Controller (PLC) is to control and automate industrial processes or machinery. It's essentially a computer used to monitor inputs (like sensors or switches) and control outputs (like motors, lights, or valves) based on a set of pre-programmed instructions.
PLCs are used in manufacturing plants, assembly lines, and other industrial environments to improve efficiency, accuracy, and safety. They can handle complex control tasks like starting or stopping machines, adjusting production speeds, and monitoring system conditions, all without the need for manual intervention.
In simple terms, PLCs help make machines and systems smarter and more efficient by automating their operation.
