Hey I'm using NI USB-8473 adapter. Am I able to send command message to can bus with USB-8473? I have a battery charger which need to be configured via CAN bus.
Here is an example message:
m e 0x0240f010 3 0x01 0x80 0xFF sets current at 50 % and voltage at
100 %.
DLC CMD ID PARAM 0 PARAM 1 Meaning
3 0x01 I U Set current and voltage
I've used a program that is attached and not sure did it work. Is there any example program which fit to this purpose or something?
Thanks!

I don't see anything wrong with the VI you attached, other than the overly bright colors. The sample command looks straightforward: you're sending three bytes with arbitration ID 0x0240f010. Those bytes are the command ID (0x01), the current (0x80, which is half of 0xFF = 50%), and the voltage (0xFF = maximum value for one byte, 100%).
Have you looked through the CAN examples provided with LabVIEW? Look at the Example Finder under the help menu, search for CAN.
