AER errors in journal

I have a PCAN-M.2 Single Channel (IPEH-004083) in an Intel NUC7i7DNBE that shows the following error in the journal: Jun 2 15:06:54 NUC7 kernel: [165382.171662] pcieport 0000:00:1d.0: AER: Multiple Corrected error received: 0000:00:1d.0 Jun 2 15:06:54 NUC7 kernel: [165382.171670] pcieport 0000:00:1d...

Re: PCAN-M.2 CAN errors in combination with a IFM RM9000

So I think I found the root cause. When configuring the PCAN-M.2 to 501 kbit, it would choose tq 400 instead of tq 12. There would be no problem in that case. When changing SJW to 2 instead of the default 1, there seems to be no problem. When measuring the bit timing using an oscilloscope, I found t...

Re: PCAN-M.2 CAN errors in combination with a IFM RM9000

Today I tried using a PCAN-USB adapter (IPEH-002022) and it didn't show any error. What is the difference between PCAN-USB and PCAN-M.2? Edit: So I noticed that the bit timing that is used by PCAN-USB when configured to 500 kbit are the following: bitrate 500000 sample-point 0.875 tq 125 prop-seg 6 ...

Re: PCAN-M.2 CAN errors in combination with a IFM RM9000

Hello, The bus is properly terminated. As I mentioned in my message there is no problem when the PCAN-M.2 is connected with the 2 custom boards. This morning I experimented a bit more with the setup, also having an additional RM9000 encoder available for testing. I found the following: When encoder ...

PCAN-M.2 CAN errors in combination with a IFM RM9000

Hello, I'm using a PCAN-M.2 interface on a Intel NUC7i7DNBE to communicate with a machine over a 500 kbit CAN bus. The CAN bus on this machine has 2 custom boards and 3 IFM RM9000 CANOpen encoders connected, so combined with the NUC there are 6 nodes on the bus. The bus is properly terminated at bot...
