How to get Alarm Count from 800xA?
I want to get number of alarms, Warning occurring in specific period in 800xA 5.1 RevD FP4.
I already configured Alarm Analysis, But here i could not find the Alarm Statistics, Such as Alarm count in specific period.
Is there any other option to collect the number of Alarms triggering in a day/period.
I know in KM, There is an event statistics, But there is not an option for Alarm Count.
Not:- i don't want to use data direct, I need it inside the 800xA.

I created a small test where I had some alarms created on cyclic basis (one every 14th second, another every 22nd second and a third every 26th second). Pure maths gives 9.3 alarms every minute or 46.6 every 5 minute.
I then deployed an Alarm Analysis with short term interval set to 5 minutes (intentionally fast to avoid having to wait hours for the results).
As you can see, the numAlarmRate is reflecting the alarms I created.
The numAverageAlarmRate and numMaxAlarmRate are statistics based on the numAlarmRate property.
The statistical OPC properties are updated on the Short term interval set on the Alarm Service Group in the Service Structure.
You may create additional Alarm Analysis service groups to be able to run analysis on varying intervals (hours, days, etc.) and specify them from each individual Alarm Analysis aspect.
