## The only SCADA system in the world that runs from a single HTML file.
**awtSCADA** is a complete industrial SCADA/HMI system that runs entirely in a web browser. No installation, no server — just open the file and start working.
### Key Features
| Feature | Details |
|---------|---------|
| 🔌 **Industrial Protocols** | IEC 61850 (MMS, GOOSE, SV), OPC UA, OPC DA, Modbus TCP, MQTT, SNMP |
| ⚡ **Function Blocks** | 53 blocks: logic, math, timers, PID, filters, interlocks |
| 🎨 **Graphic Elements** | 65 elements: pumps, valves, motors, tanks, pipes, sensors, gauges |
| 📊 **Database** | Built-in SQLite: trends, alarms, operator log, CSV export |
| 🔒 **Zero Installation** | Any browser: Chrome, Firefox, Edge, Safari. Fully offline. |
| 🐍 **Python Gateway** | Real PLC/RTU/IED connection. REST API (15 endpoints). WebSocket. |
| 📱 **Cross-platform** | Windows, Linux, macOS — any device with a browser |
| 🏭 **IEC 61850** | Full MMS/GOOSE/SV stack — unique for browser-based SCADA |
