Abstract: A system is provided for performing remote services for a technical installation comprising a first remote service system having a first tunnel connection for transmitting data between a first device at a distance from the installation and a first device internal to the installation, and a second remote service system having a second tunnel connection for transmitting data between a second device at a distance from the installation and a second device internal to the installation, wherein the second tunnel connection runs through the first tunnel connection. Performing a plurality of remote services in an installation can thereby be enabled at a high level of IT security and a high level of operational reliability of the installation, wherein the administrative effort on the part of the installation operator call be kept small.

Abstract: A method for operating, monitoring and/or configuring an automation system of a technical plant from a remote device may include a control software ensuring that the software processes of an operating and monitoring software and/or a configuration software relevant for a communication via a public network are terminated. After setting up a secure communication link from the device to the automation system via the public network, an endpoint of the communication link in the remote device is assigned a network address and the software processes of the operating and monitoring software and/or configuration software relevant for a communication via the public network are started. The data packets sent by the operating and monitoring software and/or configuration software for operating, monitoring and/or configuring the automation system are diverted to the network address by the control software.
