I will try to get to this in the next day or so, depending on my schedule (very busy until next week).  Could you post one or two real data files so I can verify things are working before I post code?  Thanks!

Hi Gray,

I am sending you the data file, please let me know if you need anything else.

I need this work to be done please help me.

Thank you

Hi Gray

I tried out in doing the Vi in a different way with very simple concept which is working up to an extend but I am not able to reset the count to 0 after 60 seconds.

can you tell me or edit this vi, so that the count after 60 seconds should come to zero and start the count again.

can you also tell me how I can average this counts after 2 minutes or 5 minutes.

Please let me know if you have any questions.

Here is the attachment of new VI

Thank you

Hello Brian,

I have plotted your data and attached the picture below.  The thing I am having a problem with is that there are several "peaks" in the data.  Are you wanting to increment by 1 every time there is a local peak?  Or just when there is a major spike (like in the middle)?

I read the data out from your file and ran it through modified VI attached to get a certain number of beats based on the threshold you specified.  Is this what you are trying to do?

Hi Reg,
Thanks for the consideration but I am not able to view the VI because I am using Labview 7.1, and the one you send me is in Labview 8.2, can you please send it in 7.1.
For the question you asked, I am concentrating only on the major spike.
Thank you.

Hi Gray,

I have posted my Vi in the earlier post, can you have a look at it and can you give me any suggestions on how to get the average of the number of beats calcualted per 5 minutes and constantly display it until the next average of 5 minutes come in to the existance.

Thank you.

Brian.

Hi Reg,

Can you please give me your VI in Labview 7.1.

Thank you.

Thanks for the ping.  Things have been busy...

Attached is something that shows to basic idea.  It will fail when the millisecond timer rolls over (about every 50 days).  Just restart and it will work or fix the logic so you account for this.  The timing is only as good as your data acquisition period.  You can improve this by using the locations of the peaks, but with this application, that may not be necessary.  It depends on how long your data acquisition takes and how many beats you get with each set of data.

Brian,
Sorry for the late reply.  Here is what I was using to measure when the threshold was reached.

Hi Reg,
Sorry for the late response, I want to know how you can program the vi to get the waveform(
