    Default Alarm storing

    Hi, I'm trying to report all the alarms in a plant.
    The AML is working well and I'm reporting in Report-viewer the alarms.
    I can only report alarms in the buffer ring, so as soos as someone resets the alarm, the data about that alarm is lost and it isn't saved in the report.
    I'm looking for the way to store and report ALL the alarms, not only the active ones in the buffer ring.
    I tried to set in project/AML the property "Save AML data" to "ring buffer and historic data" but also with this configuration it doesn't work and I lost not active alarms.
    Thank's for your help.

    Hi!

    Check your filter for the AML dataset. There is a choice between alarmbuffer and historical alarms.


    Best regards

    Thank you Fredrik! Fast and clear.
    I succeded in counting my alarms but I need to report the total duration for each alarm.
    Do you have any suggestion? I tried to do something like "Fields!TIMEGOES.Value-Fields!TIMECOMES.Value" in my chart but it doesn't work, is there a simple way to display the duration of my alarms as I did for the counting?
    I attach an example of what I mean, thank you again!

    Good Morning,

    you can use the function "datediff" in your expression instead of "-".

    See MS-Technet for details: https://technet.microsoft.com/en-us/library/aa337092(v=sql.100).aspx

    Regards,
