Supervisory Control and Data Acquisition (SCADA)

Definition

SCADA is a system used for remote monitoring and control of industrial processes, gathering real-time data from various sensors and devices to facilitate centralized management. This technology is vital in managing operations across multiple locations, providing operators with the tools to analyze, control, and optimize systems such as water treatment, electrical grids, and manufacturing lines.
