In one aspect, an electric field device for use in process automation is provided to simplify supply of an electric field device located at an installation site in the process with information originating from its process environment. At least one transponder is arranged in the area of the installation site. The transponder comprises a memory containing data with predetermined information on the process environment of the field device. The field device comprises a reader unit for contactlessly reading the data and an evaluation unit for processing the information for the functions to be carried out by the field device within the framework of process automation.

The invention claimed is: 1. An electrical field device for use in and installed at a site of a process automation system, the process automation system further comprising a transponder for storing data about the process environment of the field device and arranged in an area of the installation site, the field device comprising: a reader unit for non-contact reading of the data in the transponder, the reader unit and the transponder each having a fixed location and a proximate relationship, the reader unit capable of reading the data from the transponder at any time as required for operation of the field device; a read/write memory for storing the data read from the transponder; an evaluation unit for evaluation of the stored data as related to functions to be executed by the field device within the framework of the process automation system; and a transmitter unit for non-contact supplying of data to the transponder to be stored there as at least some of the data about the process environment of the field device, certain of the data having previously been supplied to the field device from a bus, the bus further for supplying power to the field device. 2. The electrical field device as claimed in claim 1, wherein the data represents an item selected from the group consisting of an installation site of the electrical field device, a bus address for the field device, specific process parameters for the installation site, and combinations thereof. 3. The electrical field device as claimed in claim 2, wherein the data includes a process parameter selected from the group consisting of dimensions of a container for accommodating substances, a material type of a container for accommodating substances, a type of a substance to be measured, a type of substance to be controlled, a type of substance to be regulated, and combinations thereof. 4. The electrical field device as claimed in claim 3, wherein the container is a process line. 5. The electrical field device as claimed in claim 1, wherein the transponder is a passive transponder to which energy is supplied from the field device via a magnetic field, an electromagnetic field or light. 6. The electrical field device as claimed in claim 1, wherein the data about the process environment of the field device is first supplied to the field device and then transmitted from the field device into the transponder in a non-contact manner. 7. A system for use in a process automation system, comprising: a field device installed at a site of the process automation system and comprising: a bus to communicate with other components of the process automation system, a first memory unit for storage of data, a reader unit for non-contact reading of data from a transponder at any time as required for operation of the field device, a transmitter unit for non-contact supplying of data to the transponder, the data having previously been supplied to the field device from the bus, the bus further for supplying power to the field device, an evaluation unit for evaluation of the data in storage as related to functions to be executed by the field device within the framework of the process automation system, the transponder arranged in an area of the installation site so that the reader unit and the transponder each have a fixed location and a proximate relationship, the transponder having a second memory unit for storing data about the process environment of the field device as supplied to the transponder from the field device, and wherein the transponder sends the processing environment data to the field device and the data is stored in the first memory unit of the field device. 8. The system as claimed in claim 7, wherein the transponder sends information about the process environment of the field device at specific points in time. 9. The system as claimed in claim 7, wherein the processing environment data includes an address of the bus. 10. The system as claimed in claim 7, wherein the processing environment data includes installation site information. 11. The system as claimed in claim 7, wherein the processing environment data includes process parameters for the installation site. 12. The system as claimed in claim 7, wherein the processing environment data includes dimensions of a container for accommodating substances. 13. The system as claimed in claim 12, wherein the container is a process line. 14. The system as claimed in claim 7, wherein the processing environment is a material type of a container for accommodating substances. 15. The system as claimed in claim 14, wherein the container is a process line. 16. The system as claimed in claim 7, wherein the processing environment data includes a type of a substance to be accommodated. 17. The system as claimed in claim 7, wherein the transponder is a passive transponder to which energy is supplied from the field device via a magnetic field, an electromagnetic field or light. 18. The system as claimed in claim 7, wherein the second memory unit is a read/write memory unit, and wherein the data is supplied to the field device from the transponder and transmitted from the field device into the transponder in a non-contact manner.
