Getting time stamp value for Digital Input data when configured for change detection

Hi,

 

I am using PCI 6528 card. I need to acquire Digital input from this card whenever there is change in value. i.e from 0 to 1 or 1 to 0.

I need to plot all these data on graph along with its timestamp value. currently with LabVIEW options I am getting only instances for change detected and not a timestamp. I think t0 and dt will also not in this case since dt will vary. Refer attached sample VI. Sequence followed is Configure-> Start->Read. After completion Stop and Clear.

Let me know if any solution.

 

Thanks
