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.

Abstract: A method for synchronizing a first control device and a second control device of a redundantly structured automation device that controls a technical process is provided. The first control device and the second control device are connected to each other. The first and second devices include functional components which implement the functions that control the technical process. The first control device performs the functions in the functional components for controlling the technical process in cycles, thus creating internal states of the functional components. During control of the technical process by the first control device, information about the internal states of the functional components is transferred, distributed over several cycles, to the second control device. The second control device assigns the transmitted information about the internal states to the functional components. In addition, a corresponding redundantly structured automation device is provided.

Abstract: A central control and instrumentation system with a plurality of functional modules interconnected by data transmission is provided. The functional modules are monitored by a central control module. Functional modules with a data output after completing a predefined number of action cycles, which are specific to each module, allow a provision of a fast motion functionality for simulation purposes and are subjected to a correction parameter of the number of action cycles for a user-controlled variation of the respective cycle to be completed.

Abstract: The invention relates to a method and a device for exchanging data on the basis of the OPC communications protocol, wherein at least one OPC-ready server is connected parallel to a master OPC server. An OPC client is connected to the master OPC server over a first communications link and to at least one OPC-ready server via at least one second communications link. The OPC client exchanges data over the first communications link and the master OPC server, and over at least the second communications link and at least one OPC-ready server with automatic devices, and evaluates the data transmitted by the master OPC server and at least one OCT-ready server. In the event of failure, the master OPC server is at least partially switched over from the OPC client to at least one OPC-ready server such that the program continues to run smoothly in the same place.

Abstract: A central control and instrumentation system for a technical installation is provided. The central control and instrumentation system for a technical installation includes a plurality of functional modules which are interconnected for data transmission, monitored by a central control module and activated, when needed, as a function of a triggering parameter. The triggering parameter provided for activating the functional modules by the control module is predefined by a user.
