Abstract

The present disclosure relates to a method for transferring data between an automation field device and a communication box, wherein the method comprises: voltage modulation of the supply voltage of the field device by the communication box such that a first communication signal is produced and the supply voltage has the first communication signal; demodulation of the first communication signal from the supply voltage applied to the field device by means of the two-wire line such that the first communication signal is separated from the supply voltage; current modulation of an output current of the field device by the field device such that a second communication signal is produced and the output current has the second communication signal; demodulation of the second communication signal from the output current by the communication box such that the second communication signal is separated from the output current.
