ABB Error 100000 — Firmware RobotWare — tout module fault

Error

ABB 100000 (“Firmware RobotWare — tout module fault”): This code comes in 12 variants (IRC5 / Omnicore · S4C / S4C+ / IRC5 · IRC5). Likely part: World Zones / Unité d'E/S DeviceNet (World Zones / Unité d'E/S DeviceNet).

What it means

This code comes in 12 variants (IRC5 / Omnicore · S4C / S4C+ / IRC5 · IRC5). Main case: Internal error: single, generic code of the "Internal" category of the log. The number carries no information; all the diagnostic value is in the text, in the form "<Module>.c <line> <message>" — the RobotWare firmware source file and the line that issued the error. Examples recorded in the field and in the community: Servo.c 2154, Hpjts.c 4791, Refsup.c 728, Wzone.c 1086, Servots.c 7016, pgmsym.c 3195.

What to check

  • Never treat "Internal error" as a diagnosis: note the complete module, line and message.
  • Then group by module to see the family involved (Servo = servo control, Refsup = reference supervision, Wzone = World Zones, Hpjts = manual jogging).
  • Correlate to the second with the other categories: the internal error often precedes the public message.
  • If an isolated module appears only once with no correlated event, a software reload is generally sufficient; if it recurs, trace back to the hardware.
  • Note: Does not exist in the ABB event manual: code not publicly documented, specific to the internal category. The source line varies with the RobotWare version (Hpjts.c 4713 in RW5, 4791 in RW6.08): compare modules, never line numbers, from one cabinet to another.
