Saving data at every 10 seconds

[Beginnermna]

Hi

I am getting 4 waveforms from my program, 2 time domain and 2 frequency domain. Currently I have to save them manually. What I need to do is make it automatic so that when I run the program it saves the 4 waveforms every 10 seconds. Is that doable? Can anyone please help?

It would be easier if you could add your code. Then we can make better suggestions as to what you should add and where.

Also, how do you want to save them? E.g. TDMS, binary, csv as text, ...?

Please have the code

I opened your block diagram.  Then I closed it right away.  It's way too messy for me to deal with.

I abhor messy code.  I cleanup up one of your subVIs (Sum Waveforms .vi) just to illustrate the difference between clean and messy code.

Here is your original:

Here it is after I cleaned it up:

I cleaned up one more.  The original:

Inexcusably bad.

The code really is bad…

One more cleanup (RollingAverage):

Hint: In case of "Rolling Average"=FALSE the average calculation might be wrong…

After implementing all those cleanups you should learn to use the ElapsedTime ExpressVI: it will give you a simple way of getting a boolean TRUE signal after each 10s…

Hello

Thanks for your help. Can you please tell me where I can find the Elapsed Time Express VI?

The VI can be found under the Express VIs palette when right clicking on the block diagram, in the Execution Control subpalette.

Documentation can be found online here: https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/vi-lib/express/express-execution-control/e...

Have you had a look into the time functions palette?
