Device and method for diagnosis in multi-channel-CAN-applications |
摘要 |
A CAN-network comprises several CAN-systems each having a CAN-bus and a CAN-interface which are connected to host-CPU by the CAN-bus. At least one CAN-interface is a selector interface which allows selective access to CAN-busses of other CAN-systems. Thereby it is possible to monitor data exchange on a bus by operating the selector interface in a so-called 'mirror mode' in which data of a monitored bus are automatically transferred to the bus of the selector interface. A connection to diagnosis units allows a diagnosis of the data exchange on the monitored bus.
