Introduction
Industrial Automation SCADA Systems (Supervisory Control and Data Acquisition) are centralized platforms that monitor, control, and automate industrial processes across manufacturing floors, utilities, energy grids, water treatment plants, transportation systems, and critical infrastructure. They collect realโtime data from sensors, PLCs, RTUs, and edge devices; visualize that data; enable operator control; and log historical trends for analytics, alarms, and reporting.
In an increasingly automated world, SCADA systems serve as the nerve center of industrial operations โ ensuring uptime, safety, and efficiency while enabling rapid response to process anomalies.
