Hello, LabVIEW community, I am new to LV and have developed a VI which stores data in a .csv file. I am running into an issue to which I am not able to find a solution. I want my data to look like what it is in "Expected.csv", currently looking like "Actual.csv" I am reading data from different devices, all works well when all devices are connected and running but if anyone of the device is not operational the data shifts to the left and does not stick to the column I wanted it to be in. I am not sure if I can share the VI as a whole so I decide not to but here is a snip that I have attached. Thank you for your help.

You are mixing two separate statements!(1) Your shift register should be initialized with zero, else the time will not start at zero if you do a second run during the same session. It will start at whatever accumulated time was left in the shift register from the previous run. (2) Your FOR loops can be eliminated as follows. Now just pad the array to 10 elements as already shown in my earlier message and you'll get an array of 10 zeroes if the array is originally empty. If the array already contains 10 elements, they will be left untouched. If the array contains fewer than 10 elements, it will be padded with zeroes and if it contains more than 10 elements, it will be truncated to 10. "Reshape array" is a wonderfully useful function! And if you would pad after the formatting, you would get an array of 10 empty strings, which might be a better option if zero can also be a valid entry.
