PLIN accept frames with invalid PIDs

Hey

Im working on a project that uses LIN for communication. Unfortunatley the engineers who implemented the communication messed up the calculation of the parity bits. Now all the hardware communications with invalid PIDs (e.g. 0x04). There is one frame with correct PID, which is also displayed in PLIN. But the others with incorrect PID are not displayed. Unfortunatley, I cannot change our communication.
I know this is not a problem of PLIN, it is a problem of our project.
But is there a way I can bring PLIN to show the messages with invalid PID?

Thanks for your support!

Marc

Hello,

yes, PLIN-View Pro don't show wrong PID frames (there is a filter inplemented). However, if you use our PLIN-API you will get a kind of LIN error frame, which will show you that there is a wrong PID used:

So you will see the frame as an error frame, but with no ID or data.
