Connect to PLCs, energy meters, VFDs, and sensors via Modbus TCP (Ethernet) or Modbus RTU (RS-485/RS-232). Poll intervals from 100ms.
Drag-and-drop gauges, number displays, trend charts, status indicators onto a canvas. Build your plant view without coding.
Watch multiple tags trend live. Zoom into any time window, compare tags, and export data to CSV.

No. Core functionality — Modbus polling, dashboards, alarms, and the historian — works entirely offline. The only optional internet use is sending alarm emails via SMTP, which you configure with your own SMTP server.
SCADA Desktop supports Modbus TCP (Ethernet, default port 502) and Modbus RTU over RS-485 or RS-232 serial. All four function codes — FC01 (coils), FC02 (discrete inputs), FC03 (holding registers), FC04 (input registers) — are supported.
All tag data is stored in a local SQLite database on your Windows machine. Nothing is sent to any cloud service or external server. You control your data completely.
After 15 days the application prompts you to enter a license key. You can purchase a license from the in-app store. Existing data and configuration are retained — nothing is deleted.
Yes. Some teams use SCADA Desktop for local plant-floor HMI and SCADA Cloud for remote management and multi-site dashboards. They are independent products and do not share data.
