Re: Alarm index
An alarm in WinCC OA is unique by its DP element ID, the time for the alert and the count parameter.
Can you please describe in detail what you want to use the unique index for.

Re: Alarm index
We are looking for a consecutive number of alert (malfunction number).
"Count parameter" satisfies the above?
Which WinCC OA alert_hdl properties idenfies "Count parameter"?
Thanks.

Re: Alarm index
There is no number available which counts the alerts and is increased if a new alert occurs.
The count parameter only counts the alerts for the same dp element for a pair of alert instances. If a new came alert is raised the count parameter is again 0. So it is not a count for the number of alerts for a single dp element.
What shall the alert counter be used for?
