Can we monitor the CAN bus load through a vi

[Raghu123]

Is there a way to monitor the CAN bus load through a vi? I am using USB 8473 to establish a CAN communication.

Thank You,

Hi Raghu,

Are you referring to fuctionality similar to the percentage bus load the NI CAN Bus Monitor shows?

If so, there are no built-in LabVIEW VIs that access this information.  You would have to use the available CAN VIs and implement it yourself. 

Alternativly, if you only need this for testing, you can use another NI CAN device on the bus to monitor the bus load and then simply remove this device for deployment.

Hope this helps!

Yes Michael, I am reffering to something like the % of load displayed in NI CAN Bus monitor. So is there any way that we can directly just get the percentage value from NI MAX (or CAN Bus moniotor). So that we can later feed it to a indicator.

Hi Raghu,

This is not possible.  As I said before, you will have to implement this functionality yourself.  Please see the Embedded Networks Performance Analysis for more information.
