Can bus activity

[bus monitor]

Hi all,

I'm using all ports of a PCI series 2 CAN card and I would like to monitor the bus activity using without opening bus monitor.

Does anyone know how to detect if the CAN bus is still sending messages or not using channel-API?

Sometimes the bus seems to freeze after a while and not showing any changes at all. I have to stop the vi and run again to see the change value.

I am trying to read lots of messages (each contain maximum 64 channels). I use Multi-Chan Single-Samp 1D Dbl type to read.

Thank you

On the Read task, there is an output "number of Samples Returned" look at that when running your VI.

A second thing to try is to right click on the CAN Read, click on select type, and change the output type to something with a timestamp.  If the timestamps do not change, then the messages have stopped.
