Most OEE vendors require expensive industrial middleware to talk to your PLCs. EdgeSense is a ~$500 Raspberry Pi that speaks Modbus natively, runs a local GTK (GIMP Toolkit) display, and syncs automatically when the network returns. One less six-figure line item.

Device Management

  • Device Registration & Trust Model
    Secure device registration with trust model... devices must be provisioned before they can post data.
  • USB Provisioning API
    Provision EdgeSense devices from a USB drive on first boot... no keyboard or network setup required.
  • Real-Time Device Status
    Device online/offline/syncing status visible in the admin UI and broadcast via SignalR.
  • GPIO Button Monitor
    Monitor physical Andon button presses via GPIO for operator-triggered call initiation.

Cycle Counting & Local HUD

  • GPIO Cycle Input
    Count machine cycles from any GPIO input... press events, proximity sensors, or PLC digital outputs.
  • Local SQLite Queue
    Cycle data queued locally in SQLite when the network is unavailable... no cycles lost.
  • Batch Transmission on Reconnect
    Buffered cycles transmitted in batch when network connectivity is restored.
  • Target Cycles Display
    Local GTK touchscreen shows target vs. actual cycle counts for the current shift.
  • Asset Status HUD
    Local touchscreen displays live asset status (Down, Running, Planned) with active call information.
  • Shift Information Panel
    Shift start, current run, product, and operator information displayed on the local screen.
  • Offline-Capable Operation
    Full cycle counting and local display continue when the ProAlert cloud is unreachable.
  • Modbus TCP/RTU Native Support
    Direct PLC communication over Modbus TCP and RTU without any additional middleware layer.
