A SCADA system is a combination of hardware and software that enables the automation of industrial processes by capturing Operational Technology (oT) real-time data. SCADA connects the sensors that monitor equipment like motors, pumps, and valves to an onsite or remote server.
SCADA systems are used to control and monitor physical processes, examples of which are transmission of electricity, transportation of gas and oil in pipelines, water distribution, traffic lights, and other systems used as the basis of modern society.
