SCADA

TECHNICAL DEFINITION

SCADA (Supervisory Control and Data Acquisition) is a control system architecture that uses computers, networked data communications, and graphical user interfaces for high-level process supervisory management, collecting real-time data from remote terminal units (RTUs) and programmable logic controllers (PLCs) to monitor and control industrial processes across large geographical areas or complex facilities.

BACKGROUND

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, also known as a distributed control system (DCS), which interface with process plant or machinery.

SYNONYMS & ALIASES

• Industrial control system
• ICS
• process control system
• remote monitoring

USAGE NOTE

SCADA systems are vital for managing critical infrastructure like power grids and water treatment plants.
