Abstract

A field device for automation, comprising: a housing; arranged within the housing, a field device electronics, to which a maximum power is made available via a two-wire line; a memory element for storing of data, wherein the memory element, for exchange of data and/or for energy supply, is electrically connected with the field device electronics and, at least in the case of storing the data, requires a power, which at least at times is higher than the maximum power available via the two-wire line; a first, NFC antenna, which is adapted wirelessly to receive an auxiliary energy and to provide the auxiliary energy to the field device electronics; a second antenna, which is adapted to communicate the data wirelessly and to exchange such with the field device electronics; wherein the field device electronics is adapted to supply the memory element with the auxiliary energy.
