PCI6229 card - DIsplays NaN on all channels

The setup is a test equipment running on Windows 11 + 2 Nos PCI-6229 and 1 No PCI-6514 cards + LV2024. 

 

All going good for a few months and suddenly there is a power tripping and the UPS also crashed simultaneously. The PC just went through a forced power down in the middle of a test. 

 

Once the power resumed and we started the PC, nothing worked and we tried to open MAX which responded with a message " NI-MAX could not launch because the required library mxrmcfg.dll failed to load " 

 

We then did a fresh install of DAQMX 24 drivers and LV2024 run time and started again.  This time it worked and the test started - but our happiness was short lived.  Randomly after a few hours of running suddenly the system crashed reading "NaN" on all 25 analog  channels and the only way to recover was a reboot. 

 

System is working like this as we are unable to resolve the issue whatever it is . 

 

In such situations is there is any supervising software or tool kit available to log events , so that we can later find out what went wrong ?  Any ideas ??

 

( Something like  Windows ProcMon help ? If yes I need to ask the System Administrator permission to install and run the same !) 

 

Thanks

I'm not completely sure what you're saying the problem currently is.

 

Is it

 

"Every time we reboot, it works for a few hours, then changes to all NaN outputs"

 

or

 

"It worked for a few hours one time, then changed to NaN on all outputs permanently, even after a reboot"

 

?

 

Also, are you really running PCI (not PCIe) DAQ cards?  If those are PCI, then it would indicate that your hardware is possibly quite old and it might be related to general hardware fatigue, exacerbated by the power down incident.
