Issue Details

I am using NI-XNET Bus Monitor to monitor the communication on the CAN bus and I notice that the update in Monitor tab is lagging.

Solution

At high bus loads, CAN or FlexRay messages are received at a high rate. You can reduce the Monitor update rate by setting the Update Rate Monitor in the Display Settings dialog to 500 ms or slower..
If you are monitoring NI-XNET devices on RT targets, you can also set the Data Transfer Rate in TCP/IP Settings dialog to 500ms or slower.
You may refer to High Bus Load Measurements section of Launching the Bus Monitor - NI-XNET Tools and Utilities Help for more recommendation.
