UDS HDA Problem

30 Views

Hi there,

we have a problem that a UDS HDA access does not deliver all data. For querying mass data we would like to reduce the amount of data via dividing the query time range into several intervals. Example configuration for the query:

Mode: Statistics

Method: AVG

Duration: 60

Duration Unit: M

Number Intervalls: 60

With this settings we would like to have back 60 values which are the average over one minute each. The number of rows given back is correct (60) but the last few values are missing! In the example for 60 Minutes these are the last 3 values having a value of "NA". The more data requested the bigger the effect! When requesting 8h (480 Minutes and 480 Intervals) the last 30 values are missing. The UDS logs show no errors. We also double checked with a query from Excel and get back all values.

Any clues?
