The invention relates to a system and method called autotopology of a network or advertising based network management which enables the analysis and automatic graphical and hierarchical representation of any hierarchical or flat network topology, especially a switched Ethernet (SE). The autotopology can be used for self-configured networks (for example by using zeroconf) and for any otherwise configured networks, especially using DHCP or manually configured networks. The use of zeroconf is called autoconfiguration. Autoconfiguration and autotopology enable a comfortable and safe administration of a network. Administration of a self-configured network using the autotopology data proceeds in a separate and low-priority sub-network (link local) so that the productive operation of the network remains undisturbed. The topology of the network is used as a clear possibility of administering a network. Administration of the network is possible immediately after determination of the topology.

The invention relates to a method for planning an automation system project, a method for authenticating a user during access to an automation device in an automation system, an automation system and a computer program for planning an automation system project. To improve the security concept in automation systems, the provision of a single sign-on authentication method for an automation system is proposed. A user is thus able to simultaneously register at all automation devices within an automation project using a single authentication. A fundamental part of the invention is thus to centrally project plan the single sign-on method. In other words, the basic provision of the basis for the subsequent authentication already takes place during the project planning of the automation project based on a project database. This procedure allows the realization of a single sign-on method for the complete projected automation system and thus simultaneously for all automation devices contained in the automation system.

The invention relates to a method and a system for access licensing for an automation device. In order to simplify access licensing for an automation device it is proposed to use client-side licenses. Thus the license is no longer linked to the automation device.

There is described a method for the dynamic generation of internet pages, a computer program and a computer system for carrying out said method. Internet pages are thus mostly generated when requested by a client. Script languages such as ASP or PHP are used which have a high demand for hardware resources. Computer systems with limited hardware resources, in particular, integrated systems cannot however make use of the above. A flexible and resource-saving generation of internet pages has to be achieved. Said aim is achieved by means of preparing a static internet page for the client and to prepare an add-on for the variable content components. The add-on piece is generated with a standard parser, a data file and a template. The static internet page links to the data file and this to the template. Alternatively the static internet page links to both the data file and the template.

A method and a device for planning an industrial automation arrangement, where an object model is generated from data objects, which represent automation components, and from relationships between these objects, a sequence of control actions by a user is used to select the objects from an object library and to relate them to one another. A plurality of sequences of control actions and their respective effects on the object model are stored as respective entity control trees with control steps, where at least two of the entity control trees are selected and used to generate a generalized type control tree using a first comparison, and the type of control tree is used to automatically plan the industrial automation arrangement.

The invention relates to a method and a device, and to an automation device for the dynamic generation of data prepared in a markup language and displayable with a web browser. In order to provide a web server for the dynamic generation of web pages, which web server requires as few resources as possible on the target machine, it is proposed that with the aid of a first data processing unit (1) at least one executable program module is generated on the basis of at least one text file, the program module is loaded into at least one second data processing unit (2) and the program module is executed by the second data processing unit (2) for generating the data displayable with the web browser.

摘要:
To provide a bi-directional data connection via the Internet, even across firewalls and starting from a client which is not visible as a server on the Internet, a first connection request for establishing a first transmission channel is sent from a first data processing device of a client via a data connection to a server of an automation system. The server responds to the request using a second transmission channel. The data connection is thus kept open permanently, allowing data to be sent and received bi-directionally. The operations between the client and the server are temporally independent of each other by at least one data network, in particular, the Internet. To guarantee a temporally unlimited service life of a data connection, dummy data is transmitted, for example, at regular intervals from the server to the client, even if no useful data is present, to maintain at least one data connection.
