SCADA
SCADA (Supervisory Control and Data Acquisition) is a control system architecture used for high-level process supervisory management in industrial and infrastructure environments. It enables centralized monitoring and control of remote equipment and processes, such as in manufacturing, water treatment, or power distribution, by collecting real-time data from sensors and devices. SCADA systems typically include a human-machine interface (HMI), remote terminal units (RTUs), programmable logic controllers (PLCs), and communication infrastructure.
Developers should learn SCADA when working in industrial automation, critical infrastructure, or IoT applications that require real-time monitoring and control of distributed systems. It is essential for roles involving operational technology (OT), such as in energy, utilities, or manufacturing, to manage processes efficiently, ensure safety, and optimize performance. Use cases include controlling power grids, managing water treatment plants, or automating production lines in factories.
