Abstract: A server (1) with a memory (7) that stores files for configuring an automation system. A remote client (4) accesses the files over communication links (2, 3, 5, 9, 10) via an interface (6, 8) in the server. The interface includes first means (8) for transmitting to one or more remote clients a copy of selected files in the memory. The interface further comprises second means (6) for receiving from remote clients files produced or modified by the remote clients. The first and second means of the interface convert the files between a format in the memory that can be processed by the server and a format for transmission that can be processed by the client.

Abstract: The invention concerns a device for developing, producing, engineering, and/or configuring an automation system. The device comprises a storage system wherein are recorded the required and/or produced files, during production and/or configuration. A remote client passes via an interface to access programme files and/or data files. The invention is characterized in that the interface includes first means for transmitting to one or more remote clients a copy of the or each file recorded in the storage system, the interface further comprises second means for receiving from the or each remote client files produced and/or modified.

Abstract: The invention relates to a device for provision of access to data in various data sources. Said device is provided with means which permit a user to gain a uniform central access to all data sources and a uniform visualization of the data from the corresponding data sources. The various data sources are automation devices, ERP devices, MES devices and other production relevant data sources.

Abstract: The present invention relates to a plant information system (1) with means (2) for acquiring a plurality of process information data (PI) from automation devices (5), systems (5), diagnostic devices (5), systems (5) and/or other devices (5) of a plant, and means 3b) for editing and/or presentation of the acquired process information data (PI). The plant information system (1) is characterized by means (1b) for selection, in accordance with criteria specified beforehand, of specific process information data from the plurality of process information data (PI). In this way, and with the corresponding inventive method, specific process information data from the plurality of acquired process information data (PI) which is of particular relevance for process execution or for a user can be selected, if necessary evaluated and displayed to the user.

Abstract: The present invention relates to a method for displaying information in an automation system, whereby the current information is displayed repeatedly in a ticker display pane (10), which is integrated within the human-machine interface (100). The current information displayed (11,12,13,14) is process data of the automation system that is displayed on an event-controlled basis in the ticker display pane (10).

Abstract: A process automation system includes terminals for operating and monitoring purposes, automation devices for executing control functions, and a host computer. Communication between the terminals and the automation devices is exclusively established via the host computer. The host computer may be installed remotely, in a computing center.

Abstract: A control program is provided on a network server, and a plurality of parallel instances of the control program are deployed to a respective plurality of thin client terminals over a network. A process is then independently controlled from each of the plurality of thin client terminals, thereby providing multiple terminal server-client operation.

Abstract: A rotary shift or slide valve (1) for power steering systems of motor vehicles contains a rotary slide (4) linked to a valve input element (23). A control bush (7) is guided in an axial bore (6) of the rotary slide (4) and rotatable by a limited angle. The control bush (7) forms a rotation-fixed link with a valve output element (18). Between the rotary slide (4) and the valve output element (18), there is a centering device, which contains two centering elements (32, 33), which can be rotated against each other, and at least one anti-friction element (36) located between the two centering elements (32, 33). One of the centering elements (33) forms a fixed link with the reaction piston (37) and a rotation-fixed but axially displaceable link with the valve output element (18) via a metal bellows (38). The other centering element (32) forms a rotation-fixed and non-displaceable link with the rotary slide (4).

Abstract: In a toothed-rack power-assisted steering, which is provided for motor vehicles in particular, a pinion (2) seated in a steering housing (1) is in engagement with a toothed rack (6). A servo motor (8) is disposed as a power assist, whose piston rod (10) is drivingly connected with the toothed rack (6). The two work chambers (12, 13) of the servo motor (8) are connected with a control device (18) via work lines (12, 13), which are connected with a cylinder (11) of the servo motor (8) and with the control device (18) via two connecting elements (24, 25). Each work line (14, 15) has a collar (32). Each line is held on the connecting element (24, 25) by a fastening clasp (34) which projects over the collar (32). The fastening clasp (34) has an essentially rectangular and flat base (35). An elongated slit (36), open toward one side, is located in the base (35), through which the fastening clasp (34) can be pushed from the side over the line (14, 15) and the connecting element (24, 25).
