Method and control device for starting up a in a daisy - chain - topology configuration of the sensor and a series circuit, sensor series circuit in daisy - chain - topology and restraining means

摘要

The invention relates to a method for starting up a in a daisy - chain - topology configuration of the sensor and a series circuit (106), wherein the sensor and a series circuit (106) at least one first sensor (200) with a first switch and a second sensor (202) with a second switch, wherein the second sensor (202) in a direction of a flow of current (210) through the sensor and a series circuit (106) the first sensor (200) is connected downstream of a closing of the first switch and a supply of the second sensor (202) with an electrical voltage, for the second sensor (202) to be initialized. The method comprises a step of providing a first switch signal to the first sensor (200), in order to close the first switch, wherein the first switch signal in response to a successful initializing of the first sensor (200) is provided, a step of monitoring a function of the second sensor (202) during the initializing of the second sensor (202), in order to determine whether the second sensor (202) has an error in the initializing or error-free is initialized and in order to provide an error signal if it is found that the second sensor (202) an error in the initializing, and a step of issuing a suppression signal (212) to the first sensor (200) when the error signal was provided, in order to prevent the first switch is closed.
