Hi. I have the same problem with my VI. I use a WIKA P30 pressure sensure with a DAQ NI 9209. Can someone help me? (I added my pressure.VI and an image of the excel data file output. After n seconds the program repeats the same data!). Thanks!

Why did you use Convert from Dynamic Data Type to a scalar? The red dot is a coercion from a waveform to a blue dynamic datatype at the input of the blue express VI, which then converts it to a scalar which throws away most of the datapoints. Use Index Array if you want the first waveform. Do the math on that so you keep all the datapoints.

Start with one click That will clean up about half of the dynamic data and DAQmx will automatically pull in the channel names. Then look into Configure DAQmx LogginG When your vi looks like this you'll be finished

I started a new thread for you. replying to a 5 year old thread with a new problem makes it difficult to follow what is going on 😄 Then fixed your code with less than a dozen keystrokes. Select the collector Express vi, Ctrl+Space, Ctrl+R, Ctrl+U! Then deleted the Wait and the constant. The DAQ Read will throttle the loop since it has to wait itself for samples to become available.
