NI-XNET Bus Monitor does not update while monitoring

I have 2 NI 9862 High-Speed CAN ports connected together and externally powered. I have a simple CAN XNET LabVIEW application that continuously writes frames to the CAN1 Port. I am monitoring the CAN2 PORT with the NI-XNET Bus Monitor. The Bus monitor only displays the payload data being transmitted when I first run the LabVIEW applicaton, it will not update the payload Frame CAN info as I update the payload in real time. I have to stop the LabVIEW application to see the changes in the payload data displayed in the NI-XNET BUS  MONITOR. File attached.

Hi sfrosty,

 

Are the two 9862 modules in a cDAQ or a cRIO?

 

What version of XNET and LabVIEW are you using?

The two 9862 modules are in a cDAQ-9132 running embedded windows 7.

 

What version of XNET and LabVIEW are you using?

NI-XNET Runtime 15.5.0f0

LabVIEW 15.0.0

Just to confirm, you're only writing to CAN1, then monitoring on CAN2? 

 

I ask this because I know that the XNET Bus Monitor acts as a streaming session, so it can only access a port that isn't being streamed to.

 

Is your end goal to be able to monitor CAN2 with the Bus Monitor? Or is this just to verify what is being written during development?
