# Alerts
ACRON offers the facility to create and edit [alert groups](#alarmgruppe), subgroups and [alert variables](/acron-9.3/en/anlagenkonfiguration/alarme/alarm.md). Alert variables can be moved within the [groups](#alarmgruppe) by [drag & drop](/acron-9.3/en/erklaerung_zur_bedienung.md#drag-drop).
There are two kinds of alert in ACRON:
* Alerts automatically imported from the control system.
* Alerts generated by ACRON on the basis of the user's definition.
The alert variables for control system alerts are created automatically and stored by default in the [Default group](#standard). They can be moved to any user-defined groups. Within ACRON, these alerts can only be assigned one [alert status](/acron-9.3/en/anlagenkonfiguration/alarme/alarm.md#alarmstatus).
If you want ACRONto generate custom alerts, they can be defined in the '[Alert generation](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/variablengruppe/register_alarmgenerierung.md)' area of the external variable. Note that the assigned alert variable should be a previously created individual variable.
## Alert group
[Alerts](/acron-9.3/en/anlagenkonfiguration/alarme/alarm.md) are organized into groups. Grouping brings multiple alerts together to form a larger unit, making structures clearer and more concise when there are large numbers of alerts. Alert variables can be moved within the [groups](#alarmgruppe) by [drag & drop](/acron-9.3/en/erklaerung_zur_bedienung.md#drag-drop).
Note
All alert variables automatically provided by the control system are assigned to the 'Default' group.
The 'Default' group cannot be deleted.
