Log slowly changing data

[Linf]

Hi

I'm using Labview 8.2 with the DSC module

I want to log continuously a shared variable that updates very slowly (maybe as slow as once a day). In my program I use the historical VIs in the DSC module to retrieve data from the citadel database which is used at the end of a week to generate a report. When I look at the historical data using MAX, the slowly changing shared variables appear to be logged for a short time after they have changed and then they are no longer logged until the next change, maybe the following day. Logging deadbands have been set to zero to log any change. A feature in previous versions was the "maximum time between logs" setting in Configure>>Historical menu. I think this would have solved my prob but according to the FAQ on http://www.ni.com/labview/labviewdsc/faq.htm , this has been removed in LV8.2 as it is no longer required.

Is there anything I have to do to force the same "maximum time between logs" behaviour in Labview 8.2?

Thanks

Is this variable connected to hardware?  If so, what?

The shared variable is bound to a tag from an OPC server. The OPC server reads data from an industrial motor variable speed inverter drive unit. The parameter giving me trouble is the reading for the run time of the drive which is measured in years and days and thus updates very slowly (once a day!).

Attached is a MAX screenshot of my logged data showing the large gaps between recordings. Other logged data will record continuously leaving no break in the trace.

Any help would be appreciated.
