SCADA stands for Supervisory Control and Data Acquisition. It is a computer-based control system architecture that collects data from industrial sensors and equipment in real time, allowing operators to monitor and control industrial processes remotely. SCADA systems are widely used in power grids, water treatment plants, oil and gas pipelines, and manufacturing facilities.
SCADA = Supervisory Control and Data Acquisition.
Used for real-time monitoring and control of industrial processes.
Applications: power grids, water treatment, oil & gas pipelines, manufacturing.
Key components: RTU, PLC, HMI, SCADA server, communication network.
Stuxnet (2010) was a famous cyberattack targeting a SCADA system.
SCADA is part of ICS (Industrial Control Systems) ā critical infrastructure.
Full Form: SCADA = Supervisory Control and Data Acquisition
What is SCADA? ā¢ A real-time industrial control system for monitoring and controlling remote infrastructure ā¢ Collects data from sensors (field devices) at multiple remote locations ā¢ Sends data to a central control room (HMI ā Human Machine Interface) ā¢ Operators can monitor, control, and receive alerts in real time
Components of a SCADA System:
| Component | Function |
|---|---|
| Field Devices (Sensors, RTUs) | Collect data from physical processes |
| RTU (Remote Terminal Unit) | Transmits data from field to control center |
| PLC (Programmable Logic Controller) | Controls automated machinery |
| Communication Network | Connects field devices to control center |
| HMI (Human-Machine Interface) | Visual dashboard for operators |
| SCADA Server / Historian | Stores and processes data |
Applications of SCADA:
Advantages: ā¢ Remote monitoring ā no need for on-site personnel ā¢ Real-time data collection and alerts ā¢ Reduces human error in industrial operations ā¢ Data logging for analysis and compliance
Cybersecurity Risk: ā¢ SCADA systems are critical infrastructure ā target of cyberattacks ā¢ Famous incident: Stuxnet worm (2010) attacked Iranian nuclear facility SCADA system ā¢ Industrial cybersecurity (OT security) is a growing field
Related Acronyms: ā¢ DCS: Distributed Control System (similar to SCADA, used in process industries) ā¢ PLC: Programmable Logic Controller ā¢ HMI: Human-Machine Interface ā¢ ICS: Industrial Control System (umbrella term including SCADA, DCS)
SCADA stands for Supervisory Control and Data Acquisition. It is an industrial control system that collects real-time data from field sensors (via RTUs/PLCs) and sends it to a central HMI (dashboard) for operators to monitor and control processes remotely. Applications include power grids, water treatment, oil & gas pipelines, and manufacturing. SCADA systems are critical infrastructure and are targets for cyberattacks.
