Abstract: An electronic display apparatus comprising a control device and an electronic display panel that can be turned off by the control device. In order to support an energy-saving state in which information can continue to be displayed at least to a certain extent, an electrochromic display is additionally provided that is switchable into different display states by the control device. The invention furthermore relates to an installation appertaining to automation technology, and to a method for operating an electronic display apparatus.

Abstract: A method and arrangement for planning and/or programming a project of an industrial automation arrangement by a plurality of users, wherein a workstation having at least one application for the planning and/or programming is associated with each of the users, where the project comprises a plurality of objects and objects are accessed by workstations. At least a number of the objects are grouped into object groups, each of the object groups being associated with a workstation and stored in a respective physical memory of the workstation associated with the object group, a respective key being associated with each of the object groups and being stored in a data structure which is accessed by a workstation in order to access an object, the storage location information associated with the key of the associated object group being determined by the access, and the object being accessed via the storage location.

Abstract: System and method for structuring, storing and processing of data in accordance with a generic object model, with the object model featuring at least one first element which corresponds to the type Object, with the type Object having the following attributes: a unique identification of the object for absolute referencing of the object, a logical name to label the object, and at least one link to a second element, which corresponds to a type Feature, with the type Feature having the following attributes: a unique name in relation to the relevant linked object referenced and the option of linkage to further components of type Object, to further components of type Feature and to data.

Abstract: The invention relates to a method and a system for defining structures of object and/or data models, comprising at least one schema for describing the structures. An upward and downward compatible schema evolution is achieved in that a labeling of a version of the corresponding schema is carried out in a first attribute of a schema wherein the namespace used in the corresponding schema and the type and element name used in the corresponding schema are preserved regardless of the version, wherein the types and elements are expanded only while preserving the type or element name. Unexpanded types and elements are accepted in the schemas of a newer version unchanged from the types or elements of schemas of an older version.
