Abstract

A method for communicating with an appliance has the following steps:

a) an embedded server (1) of the appliance, which has means for storing a control program (11) and a component loader (12), transmits the component loader (12) to an application server (2),

b) the component loader (12) in the application server (2) causes a business application (13) stored in a component server (3) to be transmitted to the application server (2),

c) the business application (13) is executed in the application server (2) and effects communication between a client program (14), which is executed on a client computer (4), and the control program (11), which is executed on the embedded server (1).

This permits communication between the client program (14) and the control program (11) to be set up and conducted, the business application (13) used for this purpose being automatically loaded into the application server (2).

Claims

1. A method for setting up a communication link between an embedded server (1) of an appliance and a client computer (4), where the embedded server (1) executes a control program (11) for controlling the appliance, and the client computer (4) executes a client program (14) for displaying data of the appliance and for entering control instructions to the appliance, and, when this communication link is operating, the control program (11) communicates with the client program (14) via a business application (13) which is executed on an application server (2), characterized in that the following steps are carried out to set up this communication:

a) a component loader (12) is transmitted from the embedded server (1) to the application server (2),

b) the component loader (12) causes the business application (13) to be transmitted from a component server (3) to the application server (2).

2. The method as claimed in claim 1, characterized in that the component loader (12) is transmitted from the embedded server (1) to the application server (2) using a network address stored in the embedded server (1).

3. The method as claimed in claim 1, characterized in that the component loader (12) is transmitted from the embedded server (1) to the application server (2) using a lookup server.

4. The method as claimed in claim 1, characterized in that, after transmission to the application server (2), the component loader (12) contains information about a network address for the embedded server (1).

5. The method as claimed in claim 1, characterized in that the component loader (12) contains information about a network address for the component server (3).

6. The method as claimed in claim 1, characterized in that the component loader (12) is executed on the application server (2), and thereby transmits the business application (13) from the component server (3) to the application server (2).

7. A computer program (12) for setting up a communication link between an embedded server (1) of an appliance and a client computer (4), where, when this communication link is operating, a business application (13) can be executed on an application server (2) and the business application (13) has means for communicating with a client program (14) on the client computer (4) and with a control program (11) on the embedded server (1), characterized in that the computer program (12) can be stored on the embedded server (1) of the appliance, the computer program (12) can be transmitted to the application server (2) and can be executed on the application server (2), and in that the computer program (12) has means for loading a business application (13) from a component server (3) into the application server (2).

8. The computer program (12) as claimed in claim 7, characterized in that the computer program (12) stores a network address for the component server (3).

9. The computer program (12) as claimed in claim 7, characterized in that the computer program (12) has means for loading the business application (13) from the component server (3) onto the application server (2).

10. The computer program (12) as claimed in claim 7, characterized in that the computer program (12) has means for communication between the business application (13) executed on the application server (2) and the control program (11).
