Error -1074384718: The XNET Driver Can No Longer Communicate with the Device

Issue Details

I'm occasionally seeing an XNET error from my NI 9862 module when I run my LabVIEW program as follows:

Error -1074384718: The XNET Driver can no longer communicate with the device.

When I restart the chassis and start my LabVIEW program again, everything works fine. Resetting the chassis in MAX also mitigates the error. When this error happens in MAX, the XNET module has a red X on it until the chassis is rebooted.

Solution

There are a few ways to work around this error.

Disable sleep for the network devices if the 9862 is connected to the computer via direct ethernet.
Detect this error in your code and programmatically reset the CompactDAQ or CompactRIO when it occurs.
If you're using a network switch, try directly connecting to the host computer instead.

Additional Information

This error is likely caused by an interruption of network communication between the XNET device and the computer.
