Abstract

The invention relates to a method for implementing an operating and observation system for field devices (FG1-FGN) A server device (HS1-HSN) is provided in each field device and the field devices are connected to a proxy server device (1). Said proxy server device is connected to a user device (N1-NN) on which a browser device is installed. The proxy server device interrogates the field devices in order to automatically identify the field devices which are connected to the proxy server device, and allocates a network address to each field device. A basic information message is produced by the proxy server device, said information message comprising specific electronic information about each field device, based on the results of the interrogation thereof. The respective electronic information comprises link information concerning the respective server device of each field device, such that after the basic information message has been transmitted to the user device, respective device information messages are emitted in a graphical manner, by means of the browser device, for the observation/operation of the field devices. Said device information messages can be requested from the respective server devices of the field devices.

Claims

1. A method for starting up an operating and observation system for field devices, where the field devices each include a server facility, and the field devices are connected to a proxy server facility, and the proxy server facility is connected to a user facility on which a browser facility is installed, comprising:

polling the field devices by the proxy server facility for automatically identifying the field devices connected to the proxy server facility;

detecting a respective network address for the field devices by the proxy server facility; and

generating a basic information item by the proxy server facility, the basic information item comprises respective electronic information about the field devices based on the polling of the field devices, and the respective electronic information comprises a link information item for the respective server facility in the field devices.

2. The method as claimed in claim 1,

wherein the link information item is configured such that transmission of the basic information item to the user facility is followed by the browser facility being used for graphically outputting respective device information relating to the observation/operation of the field devices which are configured for retrieval from the respective server facility in the field devices.

3. The method as claimed in claim 1, wherein basic information is stored in a memory facility in the proxy server facility.

4. The method as claimed in claim 1, wherein

basic information comprises a respective alarm status information item for the field devices.

5. The method as claimed in claim 1, wherein

basic information comprises electronic data for automatically generating a graphically outputtable control tree using the browser facility after the basic information item has been transmitted from the proxy server facility to the user facility.

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

field devices are polled by the proxy server facility for automatically identifying the field devices connected to the proxy server facility using a “

broadcast”

query.

7. The method for starting up an operating and observation system for field devices, the method for use in power plants.
