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 below shows how the units from a Simulate Signal Express VI can be changed using a Set Dynamic Data Attributes Express VI.
