Error -1967362041, DSC module, Read historical traces

[keptat]

Hi.

I'm trying to read some historical traces, but I get error -1967362041 and the message: 

HIST_ReadNumericTraceCORE.vi, \\hostname\library\Variable : IAK_SHARED:  (Hex 0x8ABC7007) Out of range.

This happens when I use VI server to execute my remote application, if I run the application locally it works normally.

Is the VI server interfering with DSC?

Any ideas?

Hi Keptat;

This error can occur if you have an incorrect Path specified under your Bind to Source section for the shared variable - this could be as simple as a typographical error in the defined path. You may also see one of the following more descriptive messages if you are autodeploying the shared variable when running a VI:

Error -1950679035 occurred at ni_tagger_lv_Read
The shared variable does not exist.

Error -1950679035 occurred at ni_tagger_lv_Write
The shared variable does not exist.

Why don't you check out this link; it explains quite well how to use shared variables with LV

Good luck

Hi, Marisol.

Thanks for yor reply. 

I just found the error: I created an "Options" control for ReadTraces.vi but somehow left the default interpolation interval as 0.

I never thought this was a problem since interpolate data was False.

I wonder why is the interval required if there's no interpolation...

Hi Keptat;

That would depend on the order of the code; if you are asking for the interpolated data in the beginning, then this problem would occur (maybe you are calling it from the beggining and then placing it inside a while or a case loop.

Glad to hear it's working now
