Hi Marvin,
Eventually I was able to replicate the fault that the customer sees in the lab.
The issue is time related because the power supply of the PCAN opto-adapter goes lower than the PCAN opto-adapter threshold and this makes it to complain.
When I reduce the TPDOs then the needed power is ...

Strange CAN BUS waveforms when using the PCAN optoadapter
Hi all,
I have 3 devices in a CAN bus system.
1st device is isolated from the others by using the PCAN optoadapter.
CAN BUS data rate is 250kB/sec
1st sends 4 TPDOS at 100ms.
2nd device sends 1 TPDO at 10ms
3rd device sends 4 TPDOs at 100ms.
Cable length 2-3meters.
