Abstract

A computer requests information that is available in an automation system, coupled to the computer, concerning the system and the information is transmitted to the computer, or prepared for the latter by the automation system. In addition to the requested information, the automation system transmits data to the computer or prepares data for the latter, which provides a definition of the requested information.

Claims

1. A communication method for an automation system (1) having a computer (4) which is coupled to the automation system (1), where the computer (4) requests information about the automation system (1) which is available in the automation system (1), the automation system (1) transmitting the requested information to the computer (4) or making it available thereto,

characterized

in that, in addition to the requested information, the automation system (1) transmits or makes available to the computer (4) data which describe the significance of the requested information.

2. The communication method as claimed in claim 1,

characterized

in that the requested information and the data are combined into information data pairs.

3. The communication method as claimed in claim 2,

characterized

in that the information data pairs are transmitted on the basis of a protocol for the worldwide web.

4. The communication method as claimed in claim 3,

characterized

in that the protocol is the HTTP protocol.

5. The communication method as claimed in one of the above claims,

characterized

in that the information and the data have been coded using a coding which is customary in the worldwide web.

6. The communication method as claimed in claim 5,

characterized

in that the protocol is the XML protocol.

7. The communication method as claimed in claim 5,

characterized

in that the protocol is the HTML protocol.

8. The communication method as claimed in one of the above claims,

characterized

in that the information also comprises configuration data about the automation system (1) and/or a technical system (10).

9. A computer program product for an automation system (1) for carrying out a communication method as claimed in one of the above claims.

10. An automation system,

characterized

in that it has been programmed using a computer program product (7) as claimed in claim 9.
