ABB Error 71414 — Concurrent changes of signal value

What it means · Ce que ça veut dire

Concurrent changes of signal value — ABB robot hardware event on the Concurrent changes of signal value (IRC5). Specific to this controller generation. Severity: Major. Field diagnosis below (French); your robot's own manual remains authoritative.

Concurrent changes of I/O signal arg value have been detected. A signal value change of I/O signal arg is aborted due to another value change of the same I/O signal. 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 Concurrent changes of signal value, 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.
• probable : The concurrent value change is due to an undesired signal change sequence in a program.
• Multiple changes of I/O signal arg might appear when a I/O signal is pulsed, e.g.
• SetDO arg , 0; PulseDO /High /PLength = 0.01, arg; WaitTime 0.01; SetDO arg , 1; The I/O signal arg will be 1 at the end, but at rare occasions there will not be any visible pulse.
• This type of sequence should be avoided.
• Verify that concurrent value changes are desired of I/O signal arg , otherwise modify the signal change sequence.
