Empty task out from DAQmx Create Virtual Channel (VI)

[sifeet]

Hi, 

I'm using a NI USB_6008 in my project and I use ao0 to provide my device with supply-voltage. And I use ai1 to measure voltage on my device. The thing is that I have been using another identical USB_6008 before, and everything worked just fine, but now when I want to use this new DAQ, it doesn't work at all and I get "empty" or "unnamed" task out. I have the right serial-number and device-number in my hardware initiation. And I have used the test panel in    "Measurement & Automation Explorer to check that the channels works properly. I have also changed the USB-port and also updated my drives. But nothing has helped. 

Unfortunately I can not send the code here since it's too big and complicated but I'll attach a screen-shot of the part the I'm stucked in with the "probe" values. 

I'll really appreciate it if someone could explain for me why I get "unnamedTask".

Hello,

I was wondering if you were able to resolve this issue.   I'm encountering the same problem.  I run the VI as part of a TestStand Sequence file.  First pass the VI runs without issue, however, all subsequent passes fail due to "Unnamed Task."   Were you able to come up with a solution?

Thanks

Just came across this while looking for something else.

Your tasks are unnamed because you haven't named them .  You can name your task when you call DAQmx Create Task.vi:

In the case of the first VI, the task is being implicitly created when the channel is created, so an "unnamed" task is the result.

Best Regards,
