Hi,

If you mean the Bus Monitor, which is integrated into MAX, there is a KB available, showing how to call the BM programaticaly. See the following Link:

Howto

If you need to access the data within your programm, you need to programm your own busmonitor using our NI-CAN api. The driver brings some examples showing the basic concept for this.

You didnt mention which development environment you are using, but normaly the driver brings examples for LabVIEW, CVI, Borland C, VB and C++.

Attached you can find a basic monitor example for LabVIEW.

The BUS Monitor can be called as shown in the KB above but you can not use the data within your program. But the monitor is able to log the data to your disc.
