SCADA (Supervisory Control and Data Acquisition) is an industrial supervision system that allows monitoring, controlling, and recording physical or logical processes in real-time. It connects sensors, actuators, PLCs, controllers, and databases in a graphical operation interface, usually centralized.
SCADA is the bridge between the shop floor and corporate systems, offering operational visibility, remote control, and data traceability.
🔧 Main Components of a SCADA System
| Component | Function |
|---|---|
| PLCs and RTUs | Field devices that execute commands and collect data |
| HMI/Interface | Operation screen displaying variables, alarms, and commands |
| SCADA Server | Processes, records, and distributes plant data |
| Database | Stores histories, alarms, events, KPIs, and reports |
| Protocols | Communication with devices: Modbus, OPC UA, DNP3, PROFINET, EtherNet/IP |
🧩 Typical SCADA Applications
- Monitoring of industrial plants, production lines, utilities
- Remote supervision of pumping stations, energy, water, and gas
- Control of clean rooms, HVAC, critical systems
- Recording of process histories and events for traceability
- Integration with MES, ERP systems, maintenance, and management dashboards
⚙️ Advanced Features
- 📊 Custom dashboards with KPIs, trends, and alarms
- 📦 Data storage in SQL, NoSQL, cloud, or local servers
- 🔄 Bidirectional communication with devices via OPC, Modbus, MQTT
- 📈 Automatic reports by shift, batch, product, or variable
- 🔐 Security with authentication, access logs, encryption, and redundancy
