Abstract

A method for changing an operating mode of a processing unit of a network node is described. The processing unit is connected to a communication and supply line for providing data communication and for providing a supply voltage. The method includes an establishing of a communication connection of the processing unit of the network node via the communication and supply line, a determination of a change of the supply voltage of the communication and supply line by the processing unit, and a setting of an operation mode of the processing unit based on the determined change of the supply voltage.
