## Abstract

A field device for automation technology, which has a metal housing for accommodating a field device electronics. On the field device at least one opening is provided, which is closable via a lid composed at least partially of a non-metallic material, wherein an RFID chip and an RF antenna are arranged in the housing in such a manner that communication and energy exchange with an RFID reading device arranged outside of the field device can transpire, and wherein the reading device is so embodied that it provides sufficient energy to the RFID chip when the energy supply to the field device is interrupted, in order to read out via the RFID antenna the data stored on the RFID chip.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A field device for automation technology, comprising:
field device electronics;
a list;
a metal housing for accommodating said field device electronics, wherein on said housing at least one opening is provided, which is closable via said lid composed at least partially of a non-metallic material;
an RFID chip; and
an RF antenna both arranged in said housing in such a manner that communication and energy exchange with an RFID reading device arranged outside of the field device can transpire, wherein:
said RFID reading device is so embodied that it provides sufficient energy to said RFID chip when the energy supply to the field device is interrupted, in order to read out via said RFID antenna the data stored on said RFID chip.

### Claim 11 (depends on 10)

The field device system as claimed in claim 10, wherein:
said RFID chip and said RFID antenna are arranged on the inside of said lid.

### Claim 12 (depends on 10)

The field device as claimed in claim 10, wherein:
said RFID chip and said RFID antenna are associated with a display support;
a display arranged on said display support is externally visible via a transparent viewing window provided in said lid.

### Claim 13 (depends on 10)

The field device as claimed in claim 10, wherein:
said RFID chip and said RFID antenna are associated with said display support;
said display support is especially a circuit board; and
said RFID chip and said RFID antenna are arranged especially on the surface of said circuit board facing the inside of said lid.

### Claim 14 (depends on 10)

The field device as claimed in claim 10, wherein:
said field device electronics communicates with said RFID chip and said RFID antenna via a wire connection or via a radio connection; and/or
said RFID chip is supplied with energy via said wire connection or said radio connection.

### Claim 15 (depends on 10)

The field device as claimed in claim 10, wherein:
the stored data includes name plate data of the field device, information concerning hardware- and/or software components of the field device, and data stored before the interruption of the energy supply to the field device, such as measurement data, diagnostic data, counter reading, etc. and/or configuration/parameter data.

### Claim 16 (depends on 10)

The field device as claimed in claim 10, wherein:
selected data, such as the bus address or the starting parameters of the field device, are stored in said RFID chip and are effective in the case of activating the field device.

### Claim 17 (depends on 12)

The field device as claimed in claim 12, wherein:
said display is an E-paper display.

### Claim 18 (depends on 10)

The field device as claimed in claim 10, wherein:
said RFID components on said lid or on said display support are manufactured in MID technology, wherein MID stands for Molded Interconnect Device.
