Abstract
A method for a deterministic selection of a sensor from a plurality of sensors, having a control unit and multiple sensors connected to the control unit by means of a three-wire bus, wherein the sensors are connected to the three-wire bus through at least two lines in parallel to one another, and a protocol frame in conformity with the SENT specification is used between the control unit and the sensors for a data exchange, and a particular sensor is selected within the protocol frame by the control unit through the predefined duration of a selection signal, wherein the duration of the selection signal is determined by the interval between a first falling signal edge and a second falling signal edge.

A method for a deterministic selection of a sensor from a plurality of sensors having a control unit and multiple sensors connected to the control unit by a three-wire bus, the method comprising:
- connecting the sensors in parallel to one another to at least two lines of the three-wire bus and a protocol frame in conformity with a SENT specification is used between the control unit and the sensors for a data exchange;
- selecting a particular sensor within the protocol frame by the control unit through the predefined duration of a selection signal;
- and
- determining a duration of the selection signal by an interval between a first falling signal edge and a second falling signal edge.
