Issue Details

When using an XNET device (NI-9866 for example) in the cDAQ-9171, I receive the following internal error in NI-MAX. 

When I look in the error log file, I see Error 0x859080B7 hundreds of times. What should I do to resolve this issue?


This is a known issue with NI-XNET 17.5, which has been addressed by Corrective Action Request (CAR) #679472. If you are using NI-XNET 17.5, upgrade the driver to a newer version.
