ABB Error 71405 — Duplicate unit mapping

What it means · Ce que ça veut dire

Duplicate unit mapping — ABB robot hardware event on the Duplicate unit mapping (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The I/O signal <arg> has the same unit mapping as another signal. Mapping more than one signal against the same bit(s) in the unit map can cause unpredictable values for these signals since their order of evaluation cannot be controlled. E.g. if an inverted group output signal is mapped to the same bits as some digital output signals, the status of these bits are depending on the order the signals are set. Le texte constructeur de ce code n'existe qu'en anglais dans les manuels ABB dont il provient. Il est reproduit tel quel ci-dessus ; le manuel de votre robot fait foi.

What to check · Que vérifier

• Inspect the Duplicate unit mapping, its wiring and connections first.
• Match this code against your robot's event-log timeline before swapping parts.
• Follow the French field checks below — they are the tested sequence for this fault.
• It is highly recommended that mapping of several signals to the same bit(s) is avoided.
