Hi,

I did below modifications of your code and it responds accordingly to data published by slave, see attached video.
- uncomment lin_dal_timeout_service(LI0) in Lin_Schedule_Ctrl
- check Motor1Temp flag and read its data in lin_master_task

I used PLIN View and load ldf there to work as Motor1 slave

Hi @PetrS

Thanks for your reply. I checked and normal working.

Sorry for late check. Because I'm out of office last week.

When I checked code, OsIf_internal.h file below need to be modified manually in the lin_commontl_proto.c ?

Thanks,
