you have to add a second generic bus on the same port and set it to 11 bit.

Yes, as long as both are generic type and same baud rate.

I know they work on the bus. My question is for IQAN part. I have tried. If I set bus as 29bit ID, then it will not read anything in IQAN for the 11bit module.

Is this still allowed in 7.00? It is now giving me an error that I was not previously getting "Multiple buses of same type" for two generic buses on same CAN node. Both are set to same baud rate, one set to 11-bit and the other set to 29-bit. As I said this has been working in 6.0 and is not working after updating to 7.0.

This was a bug that is fixed in 7.01.
