A method for control in a process control system, where a graphical user interface of said process control system is arranged with graphic representations of one or more control objects for monitoring and/or control of a process or an equipment. The control system GUI is displayed by a control system client application on a computer or workstation. In addition, one or more applications for monitoring and/or controlling at least one said control object are run in a computing process environment separate from said process control system. No code components execute in the same processing space as that running the GUI for the process control system. Any flaw or error in the extended applications cannot affect the control system program controlling an industrial process in real-time. A control system and a computer program are also disclosed.

Method for control in a process control system implemented in part by one or more computer implemented run-time processes

A computer-implemented method for creating software objects in a process control system. The method is performed by a processing tool. The method includes creating a process object in the process control system, the process object having at least two aspects. The method includes instantiating at least one instance of the process object in the process control system. The process object is defined by a control device object type having at least two aspects. The control device object type inherits at least one aspect of the at least two aspects from a control object type and inherits at least one other aspect of the at least two aspects from a device object type. There is also provided a processing tool, a computer program, and a computer program product.

Object creation in process control systems

A method for controlling real world objects in an industrial installation, which is performed in a server node and includes the steps of: receiving a connection establishment request having a user identity; authenticating the user identity; establishing a connection; receiving a service request, wherein the service request includes a reference to an aspect object and a reference to an aspect of the aspect object; forwarding the service request and the user identity to a service dispatcher module; determining a target service provider from the reference to the aspect object by querying a directory server module; and sending the service request and the user identity to the target service provider.

Controlling real world objects in an industrial installation

A setup control unit is configured to get activated via a first computer that is to become a node in the process control system and which activation is initiated by a setup tool being brought to the first computer. The setup control unit contacts a configuration control computer, supplies a setup tool identifier to the configuration control computer, accesses system information elements in the configuration control computer, presents system nodes to an operator using the system information elements, receives an operator selection of a system node, sends the node selection to the configuration control computer for registering, based on a setup tool identifier investigation, receives node parameter data associated with the selected system node from the configuration control computer and supplies the first computer with the node parameter data for making it into the selected system node.

Joining a computer to a process control system

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.

Method for accessing a function of a real-world object

A software object is positioned in structures, such as a functional structure, location structure and order structure, where each structure consists of a hierarchy of software objects. In each structure the software object inherits security from other software objects in the hierarchy. Since the software object is inserted into multiple hierarchical structures the security of the software object is inherited from software objects in multiple hierarchical structures. The user authority to interact with a software object is, in addition to the identity of the user logged in, dependent on the inherited security of the software object. As a software object is inserted, deleted and moved in a hierarchical structure the security of the software object changes.

Method and apparatus for executing industrial manufacture

The invention relates to a method for evaluating an application for controlling a process within an automation system. The application is stored within a controller, and at least two versions of it are present within the controller. The method comprises the steps of: inputting to the different versions of the application an input signal obtained from the process; executing, in the controller, tasks based on this input signal for the different versions; generating a report comprising comparisons of the outputs from the different versions of the application; and evaluating, based on the generated report, the version(s) not used for controlling the process. An improved way of revising an automation system is thereby achieved. The invention also relates to such controller and an automation system.

Method for evaluating, an automation system and a controller

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.

Distributed query of real world objects

A method and system for a client application () to request a data item from an access server () 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 () 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.

Data access method for a control system

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.
