Issue Details

I am trying to open the NI-XNET Bus Monitor while using the NI-XNET Compatibility library, but I get: Error -1074384329 occurred at Check Runtime


When using the NI-XNET Compatibility Library, we can't access the same CAN or LIN port with both the NI-CAN application the NI-XNET Bus Monitor. Stop any currently running NI-CAN applications and you will be able to access the NI-XNET Bus Monitor.

If you want to monitor the CAN bus while the program is running, you can do one of the following:
  • Migrate your application to NI-XNET. With NI-XNET you will be able to run a VI as well as run the Bus Monitor for the same port. 
  • Integrate bus monitoring into the application itself. Existing examples for CAN can be found in the LabVIEW Example Finder: Help >> Find Examples >> Browse >> Hardware Input and Output >> CAN >> NI-CAN
