Hi,
I'd like to write some signals to a file, where I mark each phase in the execution with a tag (the user can select what tag to apply during the execution) . I am trying to use the feature of LabView's Write To Measurement File express VI that adds a comment to the current chunk of data (most of the code in the below snapshot is not really important, but I highlighted the part where I add the comment):
Later I would like to read from the file and to retrieve the comment, so I am using again an express VI - this time Read from Measurement File:
(when the phase as exctracted from the "Comment" column changes, I want to do something).
The problem is that the extracted comment is almost always an empty string, since this is the way Write To Measurement File does it - it writes it only once per chunk of data, as can be seen with the "happy" comment in the below example:
So, unless I magically happen to read my data in exactly the same chunks as it was written, I most of the time get an empty Comment, which makes this feature pretty useless to me.
Anybody has any idea how to achive something like that?
Thanks in advance!
