Abstract: The disclosure relates to a method and to corresponding systems for visualizing an address space and for organizing automation-related data, wherein according to a first method variant the user interface of a display device of a computer system is divided into a plurality of configurable address space display regions. Each address space display region is divided into a first partial region and into a second partial region, wherein the address space display regions all represent a same address space that can be chosen by a user. In the first partial regions, the node network of the address space is visualized in different display modes. In the second partial regions, details of a node chosen by the user are displayed. When the user navigates in one of the first partial regions and carries out a change to the node network, the structure of the node network and relations between the nodes in all first partial regions are automatically synchronized.

Abstract: A method and device are provided for integrating single sign-on (SSO) mechanisms in a client/server system using communication according to the standard protocol OPC UA, and for performing SSO for user authentication and authorization in the system. A client is connected to an aggregating server, and the aggregating server is connected to subordinated servers via a communication network. To integrate SSO mechanisms, the aggregating server is provided with an SSO component for mapping user legitimation data used in a service call to identities in the form in which the identities are stored in the subordinate servers. To perform SSO using the SSO component, user legitimation data associated with a service call are used to automatically search for corresponding mapped identities and affected servers, and to call up an active session service for each match in each server via the mapped identity, to establish the desired access to data from the user's service invocation.

Abstract: A method is disclosed for preprocessing and providing data and information of an automation system, wherein temporally variable first data or information and temporally invariable second data or information are acquired by using at least one standardized interface. The acquired first data and the acquired second data are read in, processed, via at least one standardized interface, and reproduced for display as a whole, and/or provided for further utilization and for operating a technical installation.
