Hello

You have a legitimate problem in your system, but it is not a bug in the nidcpower Python module. The Python module is loading the driver runtime and calling into it correctly and the driver runtime is returning this error.

The more appropriate forum for this sort of issue is NI Discussion Forums or to contact NI support directly.

We have seen lots of problems with buggy Thunderbolt implementation in several vendor PCs. When you reach out to support be sure to include enough information where they can help you:

  • PC this running on
  • Operating System
  • NI-DCPower driver runtime version
  • Screenshot of what you see in MAX when you select the board (the screen where calibration data is shows)
  • Can you reset in MAX?
  • Can you self test in MAX?
  • Have you used this NI hardware in any other configurations successfully?

FYI @tobiasgordon

Closing the issue.

YES, using C# language, qty 3 PXIe-4163s work flawlessly, together, in a homebrew silicon photonics test station here at Cisco.

Can you run a C# program that uses NI-DCPower .NET API on the same system in which you see the Python failures? That would be very strange!

I did notice the error that the Python driver reported indicated an IVI: Unrecoverable Failure.
I don’t know IVI, but there is a separate tab in MAX for a configuration one can setup using NIDCPOWER.
Is IVI required?

NI-DCPower uses IVI under the hood for some things, and the error code is either coming from IVI or is coming from the driver but using an error code defined by IVI.

I have qty 3 SMUS here in NJ. And qty SMUS in CA.
They are $33K each, so maybe I am the first trying the python driver….

You are most definitely not the first one using PXIe-4163 with out Python module.

Whatever I can do on this end to assist, let me know.

What I asked before: Can you run a C# program that uses NI-DCPower .NET API on the same system in which you see the Python failures?

Yes.

Ok, so a problem with the nidcpower Python module is completely ruled out. I think you should go through NI support, Please provide as much detail as you can including troubleshooting steps. Good luck!
