ECU MC problem PXI-8513

[Madottati]

Hello,

I have created a LabVIEW tool which implements XCP under CAN. I have an ECU, and my tool is working fine with a NI 9862.

Now I transferred my software to another system with PXI-8513. A normal CAN communication with XNET is working (rest bus simulation), but the XNET 'CONNECT' command goes to timeout error -301096, and after this I see only error frames in the bus monitor.

What is the difference regarding ECU MC between PXI 8513 and cDAQ 9862? Any idea?

Hello Madottati,

which version of ECU and LV you are using?

Have you checked the port name?

Have you increase the timeout for an test?

Hi Duffy,

I am using ECUMC 15.0 and NI-XNET 15.0. LabVIEW version is 2014.

I tried that solution from the knowledge base, but I haven't found information about timing factor. Which value should I try for PXI 8513?

Hello Madottati,

can you please lock into the CAN busmonitor to see, if the acknowledge from the ECU was sent to the card.

Hi Duffy,

how can I see that? If the ECU does not send its ACK, there must be an ACK error frame on the bus monitor. I don't see acknowledge error.

Please check the can termination :

Hello lnagl,

I checked that, that was the problem 😉
