When you use the NI-CAN Transmit sample receive the same Harbor; can a virtual CAN channel (RCA or 257) be used?

I work for a company that produces and transforms electric parts. We strive to get in remission at nine of the ECU, experiences, Instrument clusters etc. I'm trying to learn how to use LabVIEW to write commands and read the data on the CAN bus. I have downloaded the NI-CAN driver. I am currently 'play' with the same reception Port.VI show in the basic frame of the finder example API folder OR. I am not able to send the number in the data to write the table that it be read by the ncReadNet Mult .vi. When I put the parameter to 'Pending entries reading' the ncGetAttr.vi returns a 0 to indicate that there are no frames to read. As a result, the Mult.vi ncReadNet does not run.

I don't have any connected equipment, I use the virtual CAN channel CAN256. Is this the reason why I can't get data frames in my queue for the Mult.vi ncReadNet to read?

CAN carry 256 and 257 are connected to eachother through software.  When you write about 256, you can read the data on 257 and vice versa.  I think the example you mention is a writing and reading on the same port, but what you want is to probably to make a copy of this VI, in order to run two at once, where it opens 256 and the other opens 257.  Then, when you write one that you will see on the other.  I think you might be able to use the test panel CAN too read an and use the example of the other.
