Saving cumulative hours into a file.

[gkrn]

Hi all,

I have a query. I am using labview 17.

I know how to store all the analog channels data acquired at the rate of 50 ms using nidaqmx device to a tdms file. But I need to know how to save the running cumulative hours in one particular test  between start and stop event. The minimum test total running time is around 100 hours. 

Also I want to know how should I retrieve and plot the saved analog channels data against this cumulative hours using tdms viewer

Thanks

So you already know how to save data to TDMS files.

Now you want to know how to save one more channel? Calculate your "running cumulative hours" value and also save it in this TDMS file…

TDMS viewer usually plots data over time. When you want to implement an "X vs Y" plotting you could create your own TDMS file viewer…

Thanks. Already I got the idea and working on it.
