In case a license (stored on CodeMeter) might be damaged or get lost or whatever custo diagnostic will not immediately stop working.
There is a "failure safety" this time can be used to rectify problems with the license.
For a NON-Clinical license the time to solve license problems is 72 hours.
For a Clinical license the time is even longer and you can work without a license for 120 hours from the moment the key has been seen last.
The time period until the notification is displayed can be changed in the service center under CSC->Sicherheits-System\MaxNofDefaultSecuritylessSeconds between 30 and 1800 seconds.
