Error / Erreur

🇫🇷 Overlapping I/O signals with different values on ActionAtSysRestart

ABB — CATALOGUE PRODUCTION

What it means · Ce que ça veut dire

Overlapping I/O signals with different values on ActionAtSysRestart — ABB robot hardware event on the Overlapping I/O signals with different values on ActionAtSysRestart (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 overlapping bit(s) in the device map with the I/O signal arg . The I/O signal arg is using Signal Safe Level arg and the I/O signal arg is using Signal Safe Level arg . I/O signals with overlapping device mapping must have the same value on the Signal Safe Level parameter ActionAtSysRestart. The I/O signal arg 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 Overlapping I/O signals with different values on ActionAtSysRestart, 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 Signal Safe Level definitions for the overlapping I/O signals in the I/O configuration.
