Abstract

A method for transferring static data and dynamic data from a measuring point at least comprising a field device of process automation technology containing a Web server to a Web browser having tabbed navigation. The static data comprises at least an identification of the measuring point, characterized in that the identification of the measuring point is displayed in the title of a tab of the Web browser having tabbed navigation. Also contemplated is a field device for performing the method.

Claims

1-13. -13. (canceled)

14. A method for transferring static data and dynamic data from a measuring point at least comprising a field device of process automation technology containing a Web server to a Web browser, comprising the steps of:

providing tabbed navigation, wherein the static data comprises at least an identification of the measuring point; and

displaying the identification of the measuring point in the title of a tab of the Web browser having said tabbed navigation.

15. The method as claimed in claim 14, wherein:

the dynamic data is at least a device state, and the device state is displayed in the tab, especially as a status signal.

16. The method as claimed in claim 15, wherein:

the device state is displayed as a favicon.

17. The method as claimed in claim 15, wherein:

the device state is given as one of the states, failed, check function, out of specification or maintenance required.

18. The method as claimed in claim 14, wherein:

the dynamic data is the identification of the measuring point.

19. The method as claimed in claim 14, wherein:

static data and dynamic data are transferred asynchronously.

20. The method as claimed in claim 19, wherein:

an Ajax application is used for asynchronous transfer.

21. The method as claimed in claim 14, wherein:

static data and dynamic data are transferred per JavaScript.

22. The method as claimed in claim 14, wherein:

HTML5 is used as markup language.

23. The method as claimed in claim 14, wherein:

at least the dynamic data is transferred as “

server push”

, especially dynamic data is sent upon a change.

24. The method as claimed in claim 14, wherein:

static and dynamic data is transferred encrypted.

25. A field device of process automation technology for performing a method comprising the steps of:

a method for transferring static data and dynamic data from a measuring point at least comprising a field device of process automation technology containing a Web server to a Web browser, comprising the steps of;

providing tabbed navigation, wherein the static data comprises at least an identification of the measuring point; and

displaying the identification of the measuring point in the title of a tab of the Web browser having said tabbed navigation.

26. The field device as claimed in claim 26, wherein:

the field device includes a data processing unit, especially a transmitter, and/or a sensor.
