Issue Details

I'm currently using VBAI with the VBAI LabVIEW interface API

My LabVIEW program runs fine but if I connect or disconnect from the network, the VBAI engine will crash. When I reboot the computer it works fine from that point forward. What is happening and how do I fix this?


This is a know issue under CAR 629493. When using the VBAI API in LabVIEW, you can not change any network information while the VBAI engine is running. This means you need to ensure every Ethernet port has a solid physical connection to the comptuer itself and you should not add any network interfaces during the application execution. 

For more information, please contact NI support.
