How to select specific data measurements to save in text files?

[Bombbooo]

I have the problem with saving data. I have more than one measured data but I need to save the data which are only selected. I tried to create the boolean lights for each data measurement to define if I want to save in the text file, but I do not know how to program it. I tried to use case structures but not sure if it's the correct way to do it.

In the attacted file, there are 2 measured data, Flow 1 and Pressure 1. I also created the boolean light for each one to select "save or not save". Does anyone have any suggestions?

Hi Bombbooo,

first you should consider going through the basic courses offered by NI to learn about dataflow programming.

As your VI is written now, you will have to stop the loop handling the buttons before the Acquire/Save loop will start to run...
