ABB Error 71499 — I/O signals in cross connection has overlapping device map

What it means · Ce que ça veut dire

I/O signals in cross connection has overlapping device map — ABB robot hardware event on the I/O signals in cross connection has overlapping device map (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

The I/O configuration of cross connection arg is invalid. The resultant I/O signal arg has an overlapping device map with the inverted actor I/O signal arg . Using I/O signals with overlapping device map in a cross connection can cause infinity signal setting loops. The cross connection has been rejected, and no functions depending on it will work. 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 I/O signals in cross connection has overlapping device map, 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.
• Correct the device map or define one of the I/O signals as simulated.
