METHOD AND ARRANGEMENT FOR VISUALIZING AN ALARM OF AN AUTOMATION OR CONTROL SYSTEM IN A GEOGRAPHIC INFORMATION SYSTEM

摘要

A method and an arrangement are described for visualizing an alarm of an automation or control system on a screen of a human machine interface (HMI), wherein a map-based view is displayed by a geographic information system (GIS) on the screen. The map-based view indicates a geographic location of at least one technical component which is related to the operation of the automation or control system, by visualizing at least one GIS object associated to the at least one technical component. The method comprises the steps of transmitting information on a newly generated alarm to the GIS, identifying the GIS object to which the newly generated alarm is associated, determining whether the GIS object is currently visible in a viewport of the map-based view, if so, including or amending a graphic alarm item in the map-based view for visual representation of the newly generated alarm, wherein the graphic alarm item is shown in connection with the GIS object, and if not, including or amending a graphic direction item in the map-based view for visual representation of the direction in which the viewport needs to be panned for making the GIS object visible.
