Abstract (en)

[origin: DE102005061392A1] The unit has an interface e.g. serial peripheral interface (SPI) (18) for realizing a query response communication with a communication controller (6). The interface approves the access of the communication controller to a data bus only when the query response communication offers normal functioning of the communication controller. The bus guardian monitors whether a number of received, decoded and synchronization messages is large and/or same of quorum, within the communication. An independent claim is also included for a subscriber of a communication system including a data bus.
