Simulate CAN signal

[svall88]

Hello,

As part of a University project it is my task to try and access the CAN bus of an inverter.

The inverter is being programmed at the moment to operate as required.

I have a USB-8473s which will be used to acquire data from the inverter when it is programmed.

I was wondering if there is a way that I may be able to simulate a CAN signal (possibly by an NI hardware device) and input that into the USB-8473s in such a way that I can create some Labview VIs and test them.

Thanks

Hello svall88,

You can use the USB-8473 to write to the CAN bus and read from the CAN bus. You could always get a second USB-8473 to "simulate" the inverter.

Let me know if that helps.

Thanks for the suggestion, I have thaught about it and I think this will be the way I will go.

This will allow me to understand how CAN communicates and how to use the signals.

Thanks

I think buying a new usb-8473s is an expensive solution. You can use a micro controller to do this job. (As an example PIC18F4580)

With NI-CAN, you could use the virtual devices. Just make sure that you only use the API available on the USB-CAN to emulate your 8473 (network interface).
