Issue Details

I am acquiring data from hardware and writing it into a file using the 'Write To Measurement File' Express VI. I am creating a set of header information for this file including information such as units, weight, volume, area or similar information. I want to change this information programmatically, how can this be done?


The easiest way to edit header information for an Express VI (which outputs Dynamic Data), is to use a Set Dynamic Data Attributes VI. The example bellow shows how add the unit and weight headers. To include more column headers just add more Set Dynamic Data Attributes VI instances as needed.
