Signal name using 1 Sample (On Demand) in DAQ Assistant

Hello all,

 

I am still new to LabVIEW 2011 (LabVIEW in general, actually). I am trying to read data from a few thermocouples that I have and log the data in a text file. The way I did it was in a "table-formatted" text file were tabs are used to break between columns, and line breaks for rows. On the top of each column, I wanted to write the name of the channel/signal that is being measured. When I used continuous sample reading using the DAQ assistant, it worked pretty well (the signals had channel names that I was able to extract and use). However, when I switched the DAQ to "1 Sample (On Demand)", the signals seemed to lose all of their attributes. I attached a couple of pictures that might help clarify what I am trying to say.

 

... Any ideas?

Hi Oennasr,

 

Can you provide the code that you are using for this application?  Are you using a property node to get the channel attributes?  This should help to better troubleshoot your issue.  Thanks!

 

Regards,
