PXI-7071 Error -1074118656 occurred at niDMM Initialize.vi

[skanagar]

Hello,

We have used 4071 DMM in the past with no issues. Recently, we transitioned to LV2016 and the MAX was also updated to v16.0.0f0 And even while running the Examples from NI (Ex: "C:\Program Files\National Instruments\LabVIEW 2016\examples\instr\niDMM\Single Measurements\Measure DC Current.vi") , we are getting Error -1074118656 occurred at niDMM Initialize.vi.

NIMAX however recognizes the instrument and it is able to pass self test and pings. Is there a fix for this issue or any root cause that is known?.

I have attached the error and IO_trace log for reference.

Thanks,

Sudharsan

That error code maps to constant NIDMM_ERROR_INTERNAL. Unfortunately that's pretty generic and lots of situations could be causing it. Please provide more detail:

• What version of NI-DMM are you using?
  • You don't mention it so I assume you didn't upgrade the driver? Please confirm.
  • How did you get the NI-DMM VIs on LabVIEW 2016?
• What Windows version are you on?
• What OS bitness are you on (32 or 64)?
• Please post a screenshot of the MAX window
• What version of LabVIEW were you previously using?

Thanks

Hello Marcos,

Please find the answers to your question

What version of NI-DMM are you using? (Is this is the PXI card or the NI-DMM soft front panel?. If it is HW , we use PXI-4071 card and if it is version of the I-DMM soft panel we use v16.0.0

• You don't mention it so I assume you didn't upgrade the driver? Please confirm. (no we did not update drivers
• How did you get the NI-DMM VIs on LabVIEW 2016?. It was part of the installation

• What Windows version are you on? Windows 7 Enterprise
• What OS bitness are you on (32 or 64)? 64-b
• Please post a screenshot of the MAX window (please refer to my original post, I have the screenshot)
• What version of LabVIEW were you previously using? LabVIEW 2014 was the previous version we were using, currently we upgraded to LV2016 Version 16.0f2 (64-bit)

Please note that the NI-DMM soft front panel works and even in Max, I am able to communicate with the PXI-4071 card. Its only when I use the standalone drivers from NI, they don't work. Please let me know if you need more information

Thanks for the reply.

In your screenshot, the device name you use is PXI1Slot6. Does this match the name as shown in MAX? None of the screenshots show this.

The only missing piece of information is whether LabVIEW was 32-bit or 64-bit. I ask this because both MAX and Soft Front Panel are 32-bit processes, so I'm wondering if NI-DMM ever worked on your system when called in a 64-bit process.

Regardless, this is strongly pointing to be an installation issue. Could you try repairing your installation or even upgrading to NI-DMM 17.1?

Thanks!
