Troubleshooting LabVIEW Error with DAQ USB 6002

[Jane_42]

Hello Everyone,

I am new to Labview and recently, while working with LabVIEW, I've encountered an error that has been quite perplexing. The error message reads: "Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another property. Task Name: _unnamedTask<42>." Despite following the provided error links and troubleshooting steps, I haven’t been able to resolve the issue.

Interestingly, this problem seems to be associated with the DAQ device I'm currently using. The code being used was running perfectly fine with the previous DAQ, USB 6346, but the new DAQ, a USB 6002, triggers this error. This leads me to believe that the issue may be related to compatibility or configuration differences between the DAQs.

I've considering that there may be specific property settings or configurations unique to the USB 6002 that need to be adjusted. Alternatively, there could be conflicts in the task settings that were not an issue with the previous DAQ but are now relevant due to the differences in the new hardware.

If anyone has experience troubleshooting similar errors or has insights into the configuration requirements for the USB 6002, your input would be greatly appreciated. I'm eager to resolve this and get the system running smoothly again.

I'm looking at a 6002 on my desk, and remember seeing "_unnamedTask" somewhere while debugging, but don't remember the context (except it was either an A/D or D/A task).

I would venture to guess you are asking the USB-6002 to do something that it can't do.  Of course, I have absolutely no idea what you asked it to do (you didn't say), no idea how experienced you are with LabVIEW, what DAQ (A/D, D/A, Digital I/O, Counter/Timer, etc.) hardware you are hoping to use, etc.

Have you tried plugged the USB-6002 into your PC, starting MAX, and opening a Test Panel to do whatever mysterious task you want to do?  Can MAX do it?  Do you know the song "Anything MAX can do, Jane can do better"?

USB-6002 is a low-cost DAQ and does not support some features available in the high-end X Series DAQ USB-6346.

What is the full message of the error? It should tell you the name of the unsupported property.
