NI-CAN CAN Receive with Bus Load Monitoring

[mr-vizsla]

Overview

This example demonstrates how to receive CAN frames via the Network Interface. 

Description

It also calculates the bus load as done in Measurement & Automation Explorer's Bus Monitor.

Requirements

LabVIEW 8.6 "or compatible"

NI CAN 2.3.6 "or compatible"

Steps to Implement or Execute Code

1.) Download and open the attached example

2.) Select your CAN device and Baudrate

3.) Run the LabVIEW example

Additional Information or References

This example displays the same arbitration ID on multiple lines if it is received more than once.  If you would like formatting like Measurement & Automation Explorer's Bus Monitor, refer to CAN Receive Frame and Display Current Arbitration Data Instead of Multiple Lines.  This example uses the Frame API.  NI-CAN driver must be installed as well.

can u please suggest me where i can find missing sub vi files for this code

I would like to see the information on the calculation, is there any way of getting that? I use Lab Windows, so please don't reply with Lab View stuff. Also, the calculations that Bus Monitor uses is way off. Has someone ever looked at that, and measured what Bus Monitor reports versus something else, like Vector CANalyzer? Here is a table I made showing the NI Bus Monitor bus load percentages compared to the Vector CANalyzer bus load percentages: NI Vector 44 83.5 37 69.7 33 63 29 55.7 22 41.7 15 27.8 11 20.8 7 13.9 4 8.4
