Inserting timestamps after set time

[xXChazXx]

I am pritty new to labVIEW and am wondering how to insert a timestamp after a set time (say 30minutes) after the temprature has risen above a set level (in this case 30C).

Thanks

hi,

Sorry i didnt get u pls explain me in brief what exactly u want.

sorry...

I am unsure how to get a timestamp to be added after a set time has passed (30min). This 30minute timespan can only start when the temp is at or above 30 C. I can get it to insert a timestamp as soon as the temprature is above 30...

Hi Chaz,

Thanks for the post and I hope your well.

If I understand the question correctly (which Im not sure I do), you want to generate a time stamp after a certain condition?

If so, in the example below we time how long the loop has been running for. The trigger is the stop button. You could change this logic to produce a true when X amount of time had passed.

However, when you say time stamp - I assume you mean you want to time stamp your data? Now normally in DAQmx the waveform data generated already contains time stamps. If your trying to build your own waveform have you tried using the Build Waveform Node?

Or maybe your trying to do this?
