A Windows SCADA application for engineers who want local dashboards, historian, and alarms without cloud lock-in. Connect directly to PLCs over Modbus TCP or RTU and keep the entire workflow on your own machine.
From $199 one-time · No credit card · No registration · Windows 10/11 (64-bit)
Plant-floor HMI, engineering stations, local historian logging, and teams that need one-time licensing with no internet dependency.
You need browser access from outside the local network, multi-site visibility, or shared dashboards for distributed teams.
SCADA Desktop runs entirely locally. No cloud accounts, no internet dependency, no recurring fees after purchase.
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.
Set threshold alarms on any tag — high, low, or equals. Alarms log with timestamps and trigger email notifications via SMTP.
All tag readings are stored in a local SQLite database. No cloud upload, no data leaving your plant. Trend back to any point in history.
Core functionality — Modbus polling, dashboards, alarms, historian — requires zero internet. Works in air-gapped networks.

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 30 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.
