A sensor device includes: a sensor module mounted on a conductor board; a sensitive element which is sensitive to a variable; a self-test control unit implementing a self-test program, the self-test control unit applying a self-test variable to the sensitive element, taking the self-test program into account; a detection unit detecting a characteristic of the sensitive element which is altered as a result of the applied self-test variable and providing an actual self-test response, taking the altered characteristic into account; and a comparator unit provided on or in the sensor module, the comparator unit comparing the actual self-test response to at least one specified setpoint self-test response and providing comparative information.

Sensor device with self-test capability

A method for transmitting data frames between a master device and one or more slave devices via a bus system having at least one request line for transmitting request data frames from the master device to the slave devices, a response line for transmitting response data frames from the slave devices to the master device and at least one selection line for activating the slave devices, the request data frames and the response data frames being transmitted together with at least one address bit for addressing one of the slave devices, the useful data bits and at least one length-indicating bit for indicating the data frame length.
