Abstract:
A look-up function and query capability of aspects associated with aspect objects is enabled in a client device. A web client application, such as a web browser, executes in the client device. The aspects are associated with functions of real world objects such as pumps, motors, mixing units, compressors, conveyors, transformers or switchgears. The client device does not need to be pre-loaded with any specific software relating to a control system other than the web browser.
Abstract:
A method to provide access to Aspects of Aspect Objects from a standard web browser. A web browser sends a request of access to a certain Aspect of an Aspect Object. The request includes a URL address. The URL address specifies the Aspect, the Aspect Object. The method enables the use of thin clients to access Aspects of Aspect Objects representing functions of real world objects connected to a control system.

Abstract:
Embodiments of the invention are directed towards providing safe updating of objects in a computerized object-based system for process and manufacturing control. Some methods in some embodiments of methods may include providing a production environment within the system comprising operative versions of computer objects and at least one related engineering environment isolated from the production environment. Some embodiments of such methods may also include importing versions of objects to the engineering environment from a related environment, allowing a group of system-modifying users to modify the imported objects for creating modified versions of these objects and barring other users from modifying the imported objects, and exporting objects from the engineering environment to a related environment, where the exporting involves replacing current versions of objects in the related environment with modified versions for making the modified versions current versions.
Abstract:
A method and arrangements in a computerized system for control operations is disclosed. The computerized is adapted for processing data associated with real world entities based on objects representing the real world entities. In the method at least one formal instance is created, the at least one formal instance containing information regarding instantiation of at least one object. At least one formal instance is associated with one or more formal instances or groups of formal instances based on information of the type of said at least one object or the at least one formal instance.
Abstract:
A computer-implemented method for the replacement of equipment in a process control system for an industrial plant, in which a replacement operation is conducted at least in part by means of a first software application component for conducting e-procurement operations whereby one or more replacement devices complying with a defined specification may be procured from one or more external suppliers, which component is functionally linked with at least one second software application component for managing runtime operational data associated with said equipment, such that e-procurement operations may be initiated via said at least one second software application component.
Abstract:
A method and system for a client application (1) to request a data item from an access server (3) in a computer controlled control system. The control system includes objects and a plurality of access servers, which said objects represent various entities that have a defined functional meaning in the control system. Each access server, such as an OPC server, may provide access to one or more real-time data, historical data, and alarm and event data items. In an embodiment the method provides means, which enables the Access Service Handler (2) component, by querying a said object, to obtain a reference for a desired data item, to find out which access server handles the said data item. The Access Service handler then makes request to the identified access server.

Abstract:
A blood treatment apparatus comprising: a blood treatment unit; a blood line configured to extract blood from a blood source, pass the blood through the blood treatment unit and deliver treated blood to a target vessel; and a fluid line configured pass treatment fluid through the blood treatment unit and deliver used treatment fluid to a fluid sink. A flow divider is arranged in the fluid line separates treatment fluid into to a first fluid section and a second fluid section, thereby electrically isolating the fluid sections such that electrical current flowing in the fluid line between the fluid sections is limited. Related manufacturing and verification methods are also described.
