Field device for determining or monitoring a physical or chemical process variable in automation technology

1. A field device for determining or monitoring a physical or chemical process variable in automation technology, comprising:

a first transmitting/receiving element in the form of a spiral;

a second transmitting/receiving element in the form of a spiral; and

an FPGA (Field Programmable Gate Array) component having existing internal connecting lines, wherein:

said first transmitting/receiving element is configured in the form of said spiral from said existing internal connecting lines;

the spiral of said first transmitting/receiving element transmits data inductively to said second transmitting/receiving element;

at least a first portion and a second portion are provided on said FPGA component;

in said first portion, a first digital measuring path composed of a plurality of software based and/or hardware based, function modules is partially dynamically reconfigured;

in said second portion a second digital measuring path composed of a plurality of software based and/or hardware based function modules is partially dynamically reconfigured;

said first transmitting/receiving element in the form of a spiral is associated with the said first measuring path; and

said second transmitting/receiving element in the form of a spiral is associated with said second measuring path.

2. The field device as claimed in claim 1 , wherein:

said spiral of said first transmitting/receiving element is configured from said connecting lines, which are arranged in a plurality of connecting line planes of said FPGA component.

3. The field device as claimed in claim 1 , wherein:

at least the spiral of said first transmitting/receiving element is configured permanently on said FPGA component; or

at least the spiral of said first transmitting/receiving element is dynamically reconfigurable on said FPGA component.

4. The field device as claimed in claim 1 , further comprising:

a control/evaluation unit, which partially dynamically reconfigures the function modules in said measuring paths, respectively in the portions, as a function of a defined, safety-critical application, so that the field device meets a required safety standard.

5. The field device as claimed in claim 4 , wherein:

said first portion and said second portion are isolated from one another by at least one spacing.

6. The field device as claimed in claim 5 , wherein:

the one or more spacings are so embodied that there is achieved between said first portion and said second portion a potential isolation in such a manner that a temperature- and/or a voltage change in one of the individual portions does not influence a neighboring individual portion, respectively the neighboring portions, and that, in the case of a defect, no connection occurs between the individual portions.

7. The field device as claimed in claim 4 , wherein:

said control/evaluation unit is permanently configured in said first portion and/or a second portion of said FPGA component.
