Write to File with Time Stamp for LVM

[Kelsey1923]

Hello,

I am relatively new to LabVIEW and thus would really appreciate your assistance/patience. I am trying to do something that seems to be very simple but I have not found a solution that has worked in manuals and online. I want to write to a LVM file in two columns one with a time stamp and one with data. I am using the express VI for Write to File. Is there a simple way to do this?

Turn your tunnel into concatenating mode so it creates a 1-D array instead of a 2-D array.

How long will this VI run?  You don't want to continually build an array at a loop boundary eating up all your memory if it runs a long time.

What's an LVM file?

I find it a lot more useful to save data in a "standard" format like CSV or better yet a tab delimited text file.

Both of these types can then be easily opened in Excel for data analysis.

A LabVIEW Measurement File (LVM) is a text based file. The specifications for the file are here.

All the separate file formats have their strengths, for Excel viewing, the .xlsx file works well too.
