Systems (SYS)

The Systems functional area (F4) provides access to vehicle subsystem status, diagnostics, and configuration.

ASLAV System View

The Systems display shows a 3D interactive vehicle model with real-time subsystem status:

HUMS Sub-Screen (F3)

Pressing F3 from the SYS overview enters the HUMS (Health and Usage Monitoring System) sub-screen, which reports the platform's UACM-monitored resources.

Monitored Resources view

The default view lists every UACM-monitored resource with its RAG health status, resolved name, and an issue-count badge:

HUMS Monitored Resources

Column Description
Status RAG health (Monitored_Resource.A_healthStatus), LRU-authoritative — see UACM Service — RAG rollup
Resource ID resourceId:instanceId
Resource Name Resolved from the resource's own Monitored_Resource_Specification/registry data instead of a raw ID
Description The resource's descriptor text
Issues Count of active faults + threshold exceedances for that resource (e.g. 2E = 2 exceedances)

Rows are sorted by RAG severity band first, then by active-issue count within each band, so the resources needing attention surface at the top.

Active Issues popup (Enter)

Selecting a row and pressing Enter opens a merged detail pane showing every active fault and threshold exceedance for that resource:

HUMS Active Issues popup

Column Description
Kind EXCEED (Threshold_Exceedance_Event) or FAULT (Fault_Event)
Description The monitoring requirement or fault identifier that fired
Detail The measured value that triggered the exceedance, or fault detail
Since Time the issue became active

Press Enter again (or select a different row) to close/refresh the popup. It is only available from the Monitored Resources view.

Faults view (F4)

F4 toggles to a flat table of all Fault_Events across every monitored resource:

HUMS Faults view

Column Description
Status RAG severity of the fault
Event ID resourceId:instanceId of the originating Fault_Event
Fault Description Free-text fault description
Occurrence Time the fault became active
Rectified Time the fault cleared (blank while still active)

Features

The Systems display provides:

  • Subsystem health status — Visual indicators for each vehicle subsystem
  • Component connectivity — Network and bus status for CAN, Ethernet, and serial devices
  • Configuration parameters — Vehicle configuration and preset management
  • Diagnostic information — Fault codes, maintenance status, and system logs

3D Vehicle Model

When built with HAS_OPENGL_VEHICLE, the SYS screen renders an interactive 3D model of the vehicle. The model shows:

  • Colour-coded subsystem status (green = OK, amber = degraded, red = fault)
  • Wheel/track sensor readings via the WheelsWidget
  • Clickable components for drill-down diagnostics
