Abstract: Sensor device, control system and method of communication between a sensor device and a control system. Sensor devices, control systems and methods for communication between sensor devices and control systems are provided. In these, sensor data are transmitted via first interfaces and redundant sensor data and/or other data are transmitted via second interfaces.

Abstract: A sensor device includes a first sensor element that generates a first sensor signal based on a varying magnetic field; a second sensor element that generates a second sensor signal based on the varying magnetic field; a signal processing circuit configured to generate a first pulsed signal based on the first sensor signal and generate a second pulsed signal based on the second sensor signal; a fault detector that detects a fault and generates an error signal indicating the fault; and an output generator that receives the error signal based on a first condition that the fault detector detects the fault, and simultaneously outputs a first output signal and a second output signal. In response to the first condition being satisfied, the output generator maintains the first output signal in a steady state and outputs the second pulsed signal as the second output signal.
