Restrictions
- Delayed Alerts can be used for CAME delay, but not for GONE delay.
- The delayed alert functionality cannot be used and is not shown for the following alert config types:
- Multi-instance alert
- Summary alert
- Delayed alerting does not work for alerts that are manually triggered by the _event attribute or come from the PLC.
- The alert delay cannot be used in combination with a hysteresis by design.
Values of all alert config types for which a hysteresis can be used have a drop-down menu that allows selecting a hysteresis for all alert ranges:
Figure 1. Value Hysteresis 
- When an alert has multiple alert ranges with an alert delay and a value meets the higher alert range, then all intermediate alerts are triggered immediately.
Note: The additional configuration of a time smoothing (_smooth config) can be used to delay a GONE message.
