Real-Time Data Streaming

WebSocket-based data delivery with sub-second latency. Values update continuously in the browser exactly as they do on native SAMMI consoles.

  • Sub-second end-to-end latency
  • Automatic reconnection
  • Multiple simultaneous sessions

40+ Industrial Widget Types

Every SAMMI DDO type renders faithfully in the browser — meters, gauges, trends, bar charts, push buttons, alphanumerics, FSLs, plots, and more.

  • Arc meters, gauges, thermometers
  • Real-time trends and plots
  • Interactive push buttons and toggles
  • Dynamic objects (DOBJ) with animation

Zero-Change Migration

Your existing SAMMI formats convert automatically to web pages. Your peer applications continue running unchanged — no recompilation, no protocol changes.

  • Automated batch conversion tool
  • All existing peers supported
  • Background images and graphics preserved

Any Browser, Any Device

Chrome, Edge, Firefox, Safari — desktop, laptop, or tablet. No plugins, no Java, no X11 forwarding required.

  • All modern browsers supported
  • No client-side installation
  • Secure HTTPS/WSS connections
