Abstract: There is described a backplane with connections for connecting functional units. The backplane has hardware resources to handle software tasks, wherein the hardware resources are redundantly implemented or comprise essentially identical hardware modules, and wherein the hardware resources are organized in such that the software tasks are dynamically assigned to the hardware resources.

Abstract: There is described an automation network, a remote access server for an automation network and a method for transmission of operating data between an automation system with one or more automation devices and a remote computer with the operating data of the automation device being transmitted via the Internet or an intranet and displayed and/or changed on the remote computer by an Internet browser. The remote access server provides the operating data for the remote computer and, for a session-oriented access, creates a software object as an image of the automation device and, if changes are to be made to the operating data by the access, a software object for simulation of the automation device and/or of the process to be controlled by the automaton device, so that any changes can be checked for permissibility and/or validity before being forwarded to the automation device.

Abstract: There is described an automation network, an access service proxy for an automation network and a method for transmitting operating data between a programmable controller and a remote computer, wherein the operating data of the programmable controller can be transmitted via the Internet or an intranet by means of the HTTP protocol and displayed and/or modified on the remote computer by an Internet browser. The access service proxy here contains a server for supplying the web pages containing the operating data of the programmable controller to the Internet browser of the remote computer, an interface, to which an engineering system can be connected so that operating data of the programmable controller can be transmitted using a communication mechanism for automation-engineering field communication via the connection between access service proxy and engineering system, and a synchronization unit for updating the content of the web pages if the operating data is modified by the engineering system.
