CAN Messages Transmission Diagnostic Analysis of Avionic System

Jiří PAŘÍZEK, Přemysl JANŮ


Digital communication bus Controller Area Network (CAN) that was originally designed for the automotive industry considering its excellent features has become to apply in the aerospace industry. In general one of the requested properties of the aerospace products is
high dependability and maintainability. The paper summarizes CAN diagnostic equipment, which enables to detect, locate and indicate errors and failures and provide characteristics required for the airborne applications. Further the paper analyses transmission CAN
messages behavior of an aircraft electronic system consisting of several modules based on the time-triggered communication mode of the CAN with CANaerospace protocol.
