Abstract: Method for integrated data handling for engineering and operation of a plant having a plurality of software applications with different functionalities, wherein the plurality of software applications are interconnected via a network, a common data model including data shared between at least two of the plurality of software applications is provided, the common data model is managed by a configuration data service, data specific to a single application is managed by an application specific configuration data service that is assigned to a number of applications such that flexible, consistent, performance-optimized and efficient management of the various heterogeneous systems in the plant is achieved.

Abstract: A method for controlling a grid of plants, wherein the method includes interconnecting distributed control systems via a network, providing a hierarchical tree structure having at least two levels (LN) for the network, assigning each distributed control system to a node of the tree structure, receiving a data request at a parent node control system, determining whether the data request is resolvable by the parent node control system, where a reply to the data request is sent if the data request can be resolved by the parent node, and where the data request is forwarded to at least one of the child nodes of the parent node if the data request is unresolvable by the parent node such that monitoring and controlling of the entire grid with respect to the inclusion of further units and the modification of already existing units is achieved in a flexible manner.
