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 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 an alarm processing system for deciding what alarm, out of a number of alarms generated in an industrial plant or process, to present to a system operator. The method includes creating hiding rules, associating each hiding rule with a real-world object, storing these rules in a storage means, receiving an alarm related to a real-world object, determining if a hiding rule is associated with the real-world object evaluating the hiding rule, deciding from the hiding rule whether to present or hide the alarm, selectively and actively hide such alarms that are decided to be hidden and not presenting the alarm to the system operator. The invention also includes an alarm processing system and a computer program for carrying out the method.
