Exception occurred: "AI Group Config"

[Robert Bestel]

Recently I have gotten a problem with my LabVIEW VI, used to acquire data from a MEA-Chip. As soon as I try to change the setup of my

PCI 6071 E I get he following error:

Exception occurred within the external code called by a call library function Node. This might have corrupted LabVIEWs memory. Save....

After closing the popup: The VI was stopped at node 0x214 of sub VI "AI Group Config".

I use "AI Config" to initialize and change the setup of the PCI 6071 E. While the initialization works without any problems, an attempt to change any parameter (for example the sample rate), by resetting the device and calling "AI Config" again, leads to that particular exception. 

Yet the actual problem is, that the VI worked perfectly for months until last week. There haven't been any changes to the measurement system, but suddenly this error pops up and I have not found any solution so far.

I even tried the PCI 6071 E on an older PC, which had formerly been used, but the problem remains.

The LabVIEW version is 7.1, both PC's run on windows XP, whereas the hardware components are fairly different, but that should not be a problem I suppose.

If anyone knows what might suddenly cause this problem please let me know.

Thanks and regards

Hello Robert Bestel,


when reading your post my first guess was that a reinstallation of the traditional DAQ driver might fix this problem.
After some research i found some similar cases in the past. Most of the time reinstalling the driver didnt fix the problem, but its worth a try.
Other users had the same problem when their PC Hardware (RAM) got corrupt. To eliminate this possiblity i suggest to run "Memtest" and "Scandisk".
Here is another Forum thread dealing with a different issue, but the suggestions might work here was well:

Its also possible that this problem might have been caused by some faulty Windows Update. So a complete reinstalltion of windows as well as all NI software could help as a last solution.
