System and method for remote maintenance and/or remote diagnosis of an automation system by means of electronic mail
First Claim
1. A data transmission system for at least one of remote maintenance and diagnosis of an automation system, which is provided with an electronic firewall, said system comprising:
- a first transmit/receive device disposed at a location of a remote user which sends a first e-mail message, via a data transmission system, to the automation system, wherein the first transmit/receive device includes an instruction encoder which packages at least one instruction in the first e-mail message; and
a second transmit/receive device disposed at a location of the automation system to receive the first e-mail message sent by the remote user, wherein the second transmit/receive device includes an instruction decoder which automatically identifies the instruction in the first e-mail message, and which transmits the instruction to an application of the automation system for which the instruction is intended.

Abstract
The invention relates to a system for remote maintenance and/or diagnosis of an automation system (2), which is provided with an electronic firewall (12). To access the automation system, for instance via the Internet from any computer connected to the Internet, it is proposed to transmit an e-mail message (16) to the automation system via a data transmission system (18) with a first transmit/receive device (3) which is disposed at the location of a remote user (1). To this end, an instruction (8) to be executed at the location of the automation system is packaged by an instruction encoder in the e-mail message to be transmitted. At the location of the automation system, a second transmit/receive device (5) is provided to receive the e-mail message sent by the remote user (1). The second transmit/receive device has an instruction decoder (11) to automatically identify the instruction in the e-mail message and forward the instruction to the application (6) for which the instruction is intended.

13. A data transmission system for at least one of remote maintenance and diagnosis of an automation system shielded by an electronic firewall, said system comprising:
-
first transmit/receive means disposed at a location of a remote user for sending a first e-mail message to the automation system, wherein the first transmit/receive means includes instruction encoder means for packaging at least one instruction in the first e-mail message to be transmitted; and
second transmit/receive means disposed at a location of the automation system for receiving the first e-mail message sent by the remote user, wherein the second transmit/receive means includes instruction decoder means for automatically identifying the instruction in the first e-mail message, and transmitting the instruction to an application of the automation system for which the instruction is intended. - View Dependent Claims (14)

15. A data transmission system for at least one of remote maintenance and diagnosis of an automation system that has at least one application and that is provided within an electronic firewall, said system comprising:
-
a first communication device disposed at a location outside the firewall and communicating with the automation system through at least one of a first e-mail message and a second e-mail message, wherein the first communication device comprises;
an instruction processor that at least either (a) packages at least one instruction for the application into the first e-mail message or (b) receives result information generated by the application in the second e-mail message; and
a second communication device disposed at a location inside the firewall and relaying at least one of the instruction and the result information between the first communication device and the automation system, wherein the second communication device comprises;
an instruction processor that at least either (a) receives the at least one instruction for the application in the first e-mail message and (b) forwards the at least one instruction to the automation system, or (a) packages the result information generated by the application into the second e-mail message and (b) transmits the result information in the second e-mail message.
