Visa Write Error -1073807265

[physicist.in.training]

Hello!

I'm working on a VI in labVIEW that turns off the output of a Keithley 6482. I'm getting an error that says "VISA:  (Hex 0xBFFF005F) No listeners condition is detected (both NRFD and NDAC are deasserted)" when I call the Visa write and close functions. The most obvious solution is that I'm calling the wrong Visa Resource Name. But I've used this resource name elsewhere in my code and it has been fine. Interestingly enough if I manually select the status of the vi as okay the code runs and turns off the Keithley output without issue, which makes me think I have the right resource name.

 

Any ideas? Thank you so much!

Does that error occur right from start of you rapplication or only after some time?

Why do you need to open/close the VISA reference with each call? (This often can lead to other problems…)
