Communication conflict caused by the same ID in PM803F 3BDH000530R1

In a CAN network, it should be ensured that the message IDs of each node are different; If two message IDs are found to be the same, it is impossible to arbitrate which message has a higher priority, and each conflict will cause the error counter to increase by 1.
/Solution/

You can use the trace recording function and error frame recording function of PCAN Diag FD to search, or use PCAN View/PCAN Explorer software to monitor online and find which CAN messages have conflicts.
CAN FD messages appear in traditional CAN networks

The PM803F 3BDH000530R1 network will report CAN FD messages as errors because the structure of the CAN message frame has changed. The CAN FD controller can simultaneously parse and transmit both CAN FD and traditional CAN messages. The error passive display interface can be seen on the Hongke PCAN-View online monitoring or Hongke handheld PCAN-Diag FD equipment.
Same baud rate but different clock frequencies

This is mainly aimed at the CAN FD network, where the higher the baud rate, the closer it will be to the physical limit. So it is not recommended for users to use different clock frequencies on the same network.
