I am continuously acquiring real time 4-20mA data at the rate of 1 sample per second, set in the DAQ assistant using cDAQ 9188 & NI9129 analog input card. While the data display in waveform can be at 1 sample per second, I would however like to have just 1 sample saved/written every 10 minutes in the "Write to Measurement File" excel sheet. I tried doing this using a case structure and a elapsed time block to control the structure. I have simply out write to measurement file inside the true statement part and wired the signal to it. The case is controlled using an elapsed time block set at elapsed time setting of 10 minutes. The false case is kept blank. The same however doesn't seem to work.
So can someone kindly help me out how I can do this. Would be indeed great to hear from someone.
