UDS using CAN Diagnostic Frame

[Brzhou]

Hi Sir, 

I am newer for this topic, so just would like to know some logic first.

For UDS, we also use can bus for communication, right ?

Then what is the general steps for UDS by labview ?

Step 1: for hardware, we can use USB 8502;

Step 2: we use Xnet or something else ?

Thanks.

USB-8502 provides the physical layer communication.

NI-XNET driver provides data link layer, on how the bits are encoded and decoded into CAN frames.

NI-ADCS provides the layers of network layer and above.

So the dependencies are: you use NI-XNET to control USB-8502 for low level CAN communication. NI-ADCS encapsulates NI-XNET API to do UDS communication.

Hi ZYOng, 

So NI-ADCS support UDS and XCP, right ?

UDS for diagnostic and XCP for measurement/calibration.

Thanks.

You need NI-ADCS for UDS and NI-ECUMC for XCP.

Thanks for your info.
