Hi,

 

One thing you can do is to go to block diagram of the VI, click 'Save for Previous Version' under 'File', and save to LV2011.

 

Thanks,

Hi,

 

Basically you may use the ARMA.vi if you have a time series of CV or use Stepwise regression.vi if you have the extracted features of testing data. Both of the methods require the prediction threshold based on historical data or experience.

Hi,

 

Does your toolkit provide the following functions?

 

  • Trend Prediction for proactive maintenance
  • Risk Radar Chart to prioritize maintenance decisions

 

Thank you.

I'm trying to get the toolkit to run under LV 13, but get tthe following error whenever the Basic Feature Extraction.vi is called:

_______________________________________________________________________________________________________________________________

Error 1 occurred at Invoke Node in signal process.lvlib:Basic Feature Extraction.vi->FE GUI_demo.vi

 

Possible reason(s):

LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
=========================
NI-488: Command requires GPIB Controller to be Controller-In-Charge.

Method Name: Control Value:Set

"Input Signal" not found

_______________________________________________________________________________________________________________________________

 

I've tried it out on 2 seperate PCs, but both running LV 13. Any ideas??
