writing single data point from a producer consumer loop or write to measurement file

[n3ow]

Good day

I am looking for a method to record a single reading of a continuous running accusation loop.

I have tried to use the write to measurement file but I get multiple data points.

I was looking to use a producer consumer loop configuration but cannot figure a way to only record a single point.

I have included a copy of my VI.

Any feedback will be great

Thank you

Hi Jay,

I am looking for a method to record a single reading of a continuous running accusation loop.

When you want to save just a single sample of your data then you need to save exactly a single sample!

I have tried to use the write to measurement file but I get multiple data points.

Because you are writing an array of samples…

You use the "N samples" mode of DAQmxRead: Use IndexArray to pick a single sample from your data array. (Or use a mean function on the array.) Then save that single sample…
