Using a CAN database with VeriStand

[vincentlg]

Hello,

I'm using a BMS which communicate via CAN with VeriStand. I've imported the device database with NI XNET (with 3 CAN nodes) and i can see under veristand correctly some acquisition parametres.

But now i want to order a state request and verify if the order is well transmitted.

For that I sent it from one node and try to see the information in an other node, and it doesn't works.

So is it the good way to check the CAN transmission or is there another way ?

Thanks a lot 🙂

Hi Vincent,

If I understand correctly, what you are doing is a loopback test. It is indeed a good practice for communication. Have you wired your CAN ports directly together? In some cases, depending on the hardware you are using, you may need some external power supply for the CAN transmission to occur.

In any case you can also check your good communication using the tool called NI XNET Bus monitor.

Does this answer you question?

Have a nice day,

Yes it's a Loopback i think. But finaly i've check some tuto with the NI support and i think it's ok. And yes i've set the correct power supply.

Thanks a lot 🙂
