Running CAN examples without CAN card?

[Ghost.]

Hello!

Is it possible running the CAN examples, CAN programs of NI in Labview on a machine without CAN card?
My home computer haven't got a CAN card, but I am going to test my application at home, too.

Thanks:

Hi ghost,

the NI-CAN driver 2.3 or later comes with a virtual interface. (CAN256, 257). These virtual ports can be used without any CAn Hardware.

Read the handbook for further restrictions.

Would anyone happen to have an example of how to do this?  I set my can interface to CAN256 and I get the following error from my code:

-1074388457 which is generated by:
CAN Initialize.vi

I have version 2.3.3f0 installed of the drivers.

Hi,

If the error number is correct it means:

" You initialized a CAN channel that is represented as an integer larger than 52 bits in the CAN message. The limit for integer channels is 52 bits. Solution: Reduce the number of bits for the channel to 52 bits or less."

That means the virtual port works but your channel seems to be to large?

The reason I posted this initially was because my vi works when hardware is present.  Still doesn't mean I am using it incorrectly, but I guessed that if it worked with hardware present, it would work with it not present.  Anyhow, if I get to figuring out why it isn't working correctly, I will post something. 

I still think an example is needed for how to use this functionality  as it could greatly enhance the ability to develop applicaitons witout requiring hardware present.
