Abstract

An automation system with a data processing device and an automation device connected to a network, with the automation device including a network server, a current operating system and an application program running under the current operating system, can be updated by transmitting a new operating system to the automation device via the network. The network can be the Internet and/or an intranet.

Claims

1. A method for updating an automation system with a data processing device and an automation device, which includes a network server, a current operating system and an application program running under the current operating system, comprising the steps of:

connecting the data processing device with the automation device via a network, and

transmitting a new operating system to the automation device via the network.

2. The method of claim 1, wherein the new operating system replaces the current operating system of the automation device.

3. The method of claim 1, wherein the current operating system is protected before the new operating system is installed.

4. The method of claim 1, wherein the data processing device operates as a client and the automation device operates as a server.

5. The method of claim 1, wherein the data processing device operates as a server and the automation device operates as a client.

6. The method of claim 1, wherein the network comprises the Internet or an intranet.

7. The method of claim 1, wherein the new operating system is transmitted via the network via a SSL-encrypted connection.

8. The method of claim 1, wherein the new operating system is transmitted via a POST command.

9. The method of claim 1, wherein the operating system is transmitted via a PUT command.

10. The method of claim 1, wherein transmission of the operating system requires authentication of the user.

11. The method of claim 1, wherein the operating system is signed with a certificate stored in the network server.
