Check: Reference Object Optional check whether the technical object to be switched is not already the reference object for an active lockout/tagout .
The check is purely informative and does not have any influence on switching.
The system logs the corresponding reference object from start to finish of a lockout/tagout. If the system notices during the check that the technical object to be switchedis already a reference object in another active lockout/tagout, a message appears on the screen to this effect.
You can also deactivate the check.
