A complex mechanism used to gather data and physical world metrics as well as perform measurement or management actions of the monitored systems for the purposes of automatic large complex real-world processes such as oil refining, nuclear power generation or water filtration. SCADA can provide automated control over very large complex systems whether concentrated in a single physical location or spread across long distances.
Supervisory control and data acquisition (SCADA) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes. It also covers sensors and other devices, such as programmable logic controllers, which interface with process plant or machinery.
