Using self_reception, can I differ the received messages between received and transmitted ones

[revillo]

Hi,

i have a NI-CAN PXI 8464 card series 2 (well, at least I hope it's series 2 🙂 ) and want to use self_reception, for that I can receive incomming messages and my one sent one. Is there a way how I can tell if a received message is a incomming one, or a transmitted one.

I'm using the Frame API with CVI and the latest NI-CAN Driver

Thanks in Advance

There is no special treatment of these frames, they are seen on the CAN bus by the receive portion of the transceiver just as any other frame transmitted on the CAN bus. So unfortunately you cannot differ them from frames received normaly over the CAN bus. The only way would be to create a logic which stores transmitted frames and are compared agains frame received in the read queue.
