Exporting historical data to text file with MAX misses columns of data?

[IngvaldB]

I am using Labview 7.1 with DSC module 7.1 and wants to export data to either excel format or .txt.

I have tried this with the historical data export in MAX, and also programmatically with the "write traces to spreadsheet file.vi" available in the DSC module. All my tags in my tag engine file (*.scf) are defined to log data and events. Both the update tag engine deadband and the update database are set to 0 %.

My exported excel or text file seems reasonalbe except that some columns of data are missing. I dont understand
why data from these tags are not in the exported files since they have the same setup in the (.scf) as other tags which are okay exported?

All defined tags can be seen using the NI hypertrend or MAX. Also the ones that are not correctly exported to file.

Appreciate comments on this.

Best regards,

I am with the same problem. Besides, some colums of data shows value which don't make sense.

Hi,

Just so you know you'll usually get more responses if you start a new thread and if you give more information. Are you using the same versions of LV and DSC? What version of MAX do you have? What do you mean by values that don't make sense? Thanks!

I am using LV and DSC 7.1 with PCI-6251 and max 4.2. In fact, just one column of values does not make sense. In attachment, follows the excel exported file. The last of column called ...V-002 that is the problem. I put probes for checking values but them shows correct. When the file is exported that to show values wrong.

The problem of missing values in column i solved putting 0% in field of deadband.

thank you for your help

The values does not make sense, because that values displayed in .vi are different the values storing in database.
