Method for operating a sensor system and sensor system

A method for operating a sensor system having at least one controller and one sensor unit,

• wherein the controller and the sensor unit are connected to each other via a two-wire physics,
• wherein data communication between the controller and the sensor unit is implemented via the two-wire physics,
• wherein the controller comprises a first microcontroller unit and the sensor unit comprises a second microcontroller unit for carrying out the data communication;
• and
• wherein the method further comprises:
• receiving a trigger message sent by the controller via the two-wire physics with the aid of the sensor unit in a receiving step;
• determining a receipt time of the receipt of the trigger message via the second microcontroller unit of the sensor unit in a receipt time determining step;
• determining a transmission time for transmitting a response message from the sensor unit to the controller based on the receipt time with the aid of the second microcontroller unit of the sensor unit in an transmission time determining step, wherein the transmission time is temporally later than the receipt time by a first predefined delay period;
• processing the trigger message with the aid of the second microcontroller unit of the sensor unit in a processing step;
• generating the response message with the aid of the second microcontroller unit of the sensor unit in a message generating step;
• and
• transmitting the response message from the sensor unit to the controller at the transmission time with the aid of the sensor unit in a transmitting step.
