Existing diagrams to extend:

  • [MCB] System Capabilities:
    • add FDIR capability
  • [SFBD] Root System Function Breakdown
  • [SAB] System Architecture

(check comments)

New diagrams to create:

  • [ES] Subsystem Hard Reset Scenario:
    • some system failure state
    • placeholder for failure identification
    • note: failure characterisation as solvable by hardware reset only
    • tackled by hard reset signal GPIO -> RST line

Next steps:

just model a placeholder function for system failure and identification, to expand as part of #38
(use involved states to convey system failure)

at the System Analysis level, let's actually have a path to represent the telecommand/execution/report pattern, leading to "system does X" not unlike the fault identification placeholder:

  • operator issues X t/c
    • g/s sends X t/c
      • system receives X t/c
      • (switch to a Downlink mode: through change mode, collect telemetry -- thanks @muhamedshaheenar for pointing this out!)
      • system does X
      • system sends X report
    • g/s receives X report
  • operator interprets X report

at the other end of "system does X", a link to telemetry generation should also be made for when this function is triggered automatically and there is no option to immediately downlink the report.

[FEATURE] HARD RESET @ SYSTEM LEVEL
6380d97 
in [SFBD] Root System Function Breakdown:
- add functions to issue, send and receive HR requests.
- add error detections post HR command execution
- add error report downlink request functions
- rename O-S/S to general HR for simplicity
- add two functional chains to denote telecommanded and automated
functions, hid them from view in the [SFBD]

create clones of main [SAB] to highlight those functional chains:
- [SAB] System Architecture View of hard reset commands
-highlighted the created funtional chains
