Abstract

A display and operating unit having a web application for operating a field instrument and a method of operating a field instrument having a display and operating unit having a web application, wherein the display and operating unit is connectable to the field instrument; wherein at least one parameter of the field instrument is visualized on the display and operating unit by means of the web application and a parameterization of the field instrument s made possible and the web application for the visualization and/or parameterization is executed in a browser; wherein the browser is executed on the display and operating unit; and wherein the browser and/or the web application has/have an interface with which direct access to components or operating system components of the display and operating unit, to components of the field instrument and/or to external units is carried out.

Claims

1. A display and operating unit having a web application for operating a field instrument, wherein the display and operating unit is connectable to the field instrument;

wherein at least one parameter of the field instrument is visualized on the display and operating unit by means of the web application and a parameterization of the field instrument is made possible and the web application for the visualization and/or parameterization is executed in a browser; and

wherein the browser is executed on the display and operating unit,

wherein at least one of the browser and the web application has an interface that is configured to carry out direct access to components or operating system components of the display and operating unit, to components of the field instrument and/or to external units.

2. The display and operating unit in accordance with claim 1, wherein the field instrument has a web server.

3. The display and operating unit in accordance with claim 1, wherein the web application is written in HTML, JavaScript and CSS.

4. The display and operating unit in accordance with claim 1, wherein the interface is a JavaScript interface.

5. The display and operating unit in accordance with claim 1, wherein the display and operating unit has a web engine and a JavaScript interface for executing JavaScript code.

6. The display and operating unit in accordance with claim 1, wherein the web engine has a program library.

7. The display and operating unit in accordance with claim 1, wherein the web engine is implemented in the programming language C++.

8. The display and operating unit in accordance with claim 1, wherein the operating system components comprise at least one driver for a file system, at least one driver for the display and operating unit and/or at least one driver for a network.

9. The display and operating unit in accordance with claim 1, wherein the display and operating unit is an engineering tool, a smartphone, a tablet PC, a notebook or a desktop PC.

10. The display and operating unit in accordance with claim 1, wherein the display and operating unit is connected to the field instrument via an Ethernet connection.

11. The display and operating unit in accordance with claim 1, wherein the external unit is a mobile pluggable USB memory.

15. A method of operating a field instrument having a display and operating unit having a web application in accordance with at least one of the preceding claim 1, wherein the display and operating unit is connected to the field instrument via an Ethernet connection.

12. A method of operating a field instrument having a display and operating unit having a web application, wherein the display and operating unit is connected to the field instrument;

the method comprising the steps of;

visualizing at least one parameter of the field instrument on the display and operating unit by means of the web application;

making possible a parameterization of the field instrument; and

executing the web application for the visualization and/or parameterization in a browser;

wherein the browser is executed on the display and operating unit, wherein at least one of the browser and the web application has an interface with which direct access to components or operating system components of the display and operating unit, to components of the field instrument and/or to external units is carried out.

13. The method of operating a field instrument in accordance with claim 12, wherein the JavaScript interface has a web engine for executing JavaScript code.

14. The method of operating a field instrument in accordance with claim 12, wherein the display and operating unit is connected to the field instrument via an Ethernet connection.
