Method for providing data for a mobile device from a field device, computer program and arrangement for executing same

1. A method for providing static data and dynamic data of a service/display menu for a mobile device from a field device of process automation, wherein the field device contains identification data, especially field device type and firmware version, and, associated therewith, a total amount of static data and dynamic data, the method comprising the steps of:

upon query of the mobile device, dynamic data and/or static data are transmitted with a data transmission rate from the field device to the mobile device via a wireless interface, especially via Bluetooth or WLAN, especially according to a standard of the IEEE 802.11 family;

static data required for application, especially for representation, and/or changing of transmitted dynamic data are transmitted from the field device to the mobile device, when the static data corresponding to the identification data are not already present in the mobile device, wherein these static data make up only a portion of the total amount of static data in the field device; and

an application, especially a representation, and/or changing of the transmitted dynamic data by the mobile device is enabled with the portion of the static data, wherein these static data are stored in a memory in the mobile device.

2. The method as claimed in claim 1 , wherein:

the static data concern the structure, especially hierarchical structure, of a service/display menu embodied for servicing the field device, visibility of the service/display menu, value ranges of parameters, dependencies of parameters, texts of the service/display menu in at least one standard language, especially texts of the service/display menu in English, and/or visibility of parameters, especially as a function of the field device and/or as a function of hardware connected to the field device.

3. The method as claimed in claim 1 , wherein:

the dynamic data concern measured values and these are displayed on the mobile device; and/or

the dynamic data concerns parameters and these are displayed on the mobile device, changed and/or transmitted back to the field device for the purpose of changing settings of the field device.

4. The method as claimed in claim 1 , wherein:

a point-to-point connection is established between the field device and the mobile device.

5. The method as claimed in claim 1 , wherein:

at least the dynamic data are transmitted by means of a binary communication protocol.

6. The method as claimed in claim 1 , wherein:

other static data different from the static data already transmitted are transmitted from the field device to the mobile device in the background in the case of a not fully utilized data transmission rate.

7. The method as claimed in claim 1 , wherein:

especially after an initial connection between field device and mobile device, other static data of the total amount of static data still lacking are downloaded to the mobile device from another device, especially a network server, via a second wireless interface, especially via a mobile radio connection or per WLAN, especially according to a standard of the IEEE 802.11 family, or via a mobile data carrier, especially a USB flash memory or an SD card.

8. The method as claimed in claim 7 , wherein:

expanded media contents, especially texts of the service/display menu in additional languages, operating instructions, photos and/or videos are transferred to the mobile device via the second wireless interface or the mobile data carrier.

9. The method as claimed in claim 1 , wherein:

the visual representation of the service/display menu is calculated in the mobile device.

10. The method as claimed in claim 1 , wherein:

additional data are sent by the field device to the mobile device and displayed on the mobile device, independently of the static data and dynamic data currently displayed on the mobile device, when parameter and/or measured values assume certain values.

11. A computer program, which has software means, which serve for performing a method as claimed in claim 1 , wherein:

the computer program is executed in a field device and/or a mobile device.

12. An arrangement comprising:

at least one field device and at least one mobile device for performing a method as claimed in claim 1 .

13. The arrangement as claimed in claim 12 , wherein:

the field device has a connection to a fieldbus, especially based on HART, wireless HART, PROFIBUS PA, PROFINET, ModBus, FOUNDATION Fieldbus or EtherNet/IP, and/or the field device has a 4 . . . 20 mA interface.

14. The arrangement as claimed in claim 12 , wherein:

the field device is a two conductor device.

15. The arrangement as claimed in claim 12 , wherein:

the field device is embodied for use at least according to Ex ib.
