Abstract

An exemplary servicing system for a field device in an automation engineering installation. The servicing system is equipped with at least one sensor for converting a physical variable into an electrical variable and/or with at least one actuator for converting an electrical variable into a physical variable and also with a display device for presenting graphical characters. To dynamically provide a relatively high density of information, at least one subregion of the display device outputs a two-dimensional code, the content of which is alternatively made dynamic on the basis of the respective operating state of the field device and can be scanned by a mobile reader.

Claims

1. A servicing system for a field device in an automation engineering installation, comprising:

at least one of;

at least one sensor for converting a physical variable into an electrical variable; and

at least one actuator for converting an electrical variable into a physical variable; and

a display device for presenting graphical characters, wherein at least one subregion of the display device is designed to output a two-dimensional code, the content of which is alternately dynamic on the basis of the respective operating state of the field device and can be scanned by a mobile reader.

2. The servicing system as claimed in claim 1, wherein the reader includes at least one camera for recording the two-dimensional code and a display apparatus for presenting detailed information items and also processing means that are suitable for decoding the two-dimensional code and for conditioning its content for display.

3. The servicing system as claimed in claim 1, wherein the two-dimensional code provides at least one information item that refers to a location at which detailed information items can be retrieved, the detailed items being unsuitable for display on the display device of the field device based on scope or type.

4. The servicing system as claimed in claim 3, wherein the reader includes at least one camera for recording the two-dimensional code and a display apparatus for presenting the detailed information items and also processing means that are suitable for decoding the two-dimensional code and for conditioning its content for display.

5. The servicing system as claimed in claim 4, wherein the two-dimensional code refers to a location at which detailed information items are kept for retrieval.

6. The servicing system as claimed in claim 5, wherein the reader has a communication interface that is suitable for setting up a communication link to the location on the Internet at which the detailed information items are kept for retrieval.

7. The servicing system as claimed in claim 5, wherein the reader is equipped with a database that contains the detailed information item from the location at which the detailed information items are kept for retrieval and provides it offline.
