KWP2000 over CANopen, J1939

Hello,

I have may have asked this question earlier, but I have still not been able to get a clear answer for this.

From what I know, KWP2000 (ISO 15765) is standard for Diagnostics over CAN. CANopen, J1939 are one of the many application layer implementations.

Can KWP2000 be used on CANopen, J1939 or do they have a separate protocol for diagnostics over CAN? I searched over the net, but did not find anyone using CANopen or J1939 in conjunction with KWP2000, so am a bit confused.

We have implemented a simple protocol in our module for diagnostics over CAN. Now a customer is asking us to follow the KWP2000 protocol for the same. Also there are couple of other customers who want CAN communication to be as per CANopen and J1939 respt. So can I go ahead and implement the KWP2000 protocol stack and use it in my product irrespective of CANopen, J1939, etc.

Rgrds,
