Alarms not displayed in Citadel database in MAX

[hema]

I am using LabVIEW DSC 7.0. In the Tag Monitor, i can see the Alarm condition of the tag. In the VI front panel also , the alarms are listed on the Alarm and Event Display table. But When open historical data in MAX, the Alarm Display is blank.Why is this.
And when i use Alarm and Event Query to SpreadsheetFile.vi, the file (that is in text or HTML format) is not created. What to do.
Thank you,

LabVIEW DSC 7.x's DSC Engine has an "internal" alarm server and can now distinguish between "live" alarm and logged historical alarm. In Tag Monitor, the Alarm and Event Display you see the "live" alarms. However, if you query in MAX an A&E database you will get the logged alarms from the MSDE SQL Server database.

In LV DSC 6.x all alarms had to be logged to Citadel to appear.

Therefore, DSC 7.x has the advantage to use properly the setting in the Tag Configuration Editor (TCE), where you can enable the Event/Alarm to be logged/printed.

Can you check if all your Tags have in TCE>Operations correctly enabled Log/Print Events?

Let me know

I have the same problem and discussed this with NI. But they couldn't reproduce this bug in
Labview 7.0. With Labview 6.1 I had no problems with alarm logging, but after upgrading to
Labview 7.0 only some alarms appear in the historical alarm view, but not all. I have not
changed my TCE configuration file since LV6.1(all alarm bits are set to log/print events).
I solved this problem with the following procedure: I installed parallel to my existing
Labview 7.0 runtime installation the Labview 7.1 runtime.Then I loaded one time the .scf
file with the Labview 7.1 TCE (I don't no if this is necesarry). After this I started my
application in Labview 7.0 Runtime and all alarm were dispayed in historical alarm view.
Has any one an idea which component I must
change in LabView 7.0 to solve this problem,
so that I don't have to install the Labview 7.1 runtime?

Did you ever get this resolved? I'm having exactly the same problem with LV 7.0 DSC / Citadel 5.

No, this is an open NI-request until yet. They want that I should reproduce the issue with the Demo OPC Server
that ships with LabVIEW. But I have no time to do this. The only solution they recommend me is to install LV 7.1.
