From NI Max 18x, clicking on Test Panels for either a NI PXIe 4140 or a NI PXIe 4113, brings up the Instrument Studio, which proceeds to show an initialization error -1074106671. Our code errors out with the same error when calling "niDCPower Initialize with Channels". Instrument Studio claims "Error description not found", our code claims "An internal error has occurred".
This setup used to work, some equipment on GPIB/USB and USB was moved around but the PXI mainframe wasn't touched. I've updated NI-488, VISA, Switch, DCPower and DAQmx to the latest, but no luck.
How does one track this error down?
Slightly different error code, with the problem manifesting itself on machines with 256 to 512 MB RAM. I don't think we have any with less than 8 GBytes now, the latest have 16.
If you remove the GPIB/USB component of your set up completely, do you still see this error?
Try moving your PXI cards to a different slot or use different cards to see if it's a problem with the hardware.
