With the Alarm Analysis object, you can create a custom alarm color scheme that provides the user with visual cues. You create the color scheme by selecting foreground colors for alarm statuses and background colors for alarm priorities. If you do not select the Alarm Status or Alarm Priority columns when setting the data source, the threshold colors will have no effect.
When a color is applied to alarm statuses, all the data (text) in the row for a specific alarm status will be displayed in that color.
The background color determines the color of the area of the row the alarm text is displayed on and indicates the alarm priority. For example, low priority alarms could have a white background, medium priority alarms could have a gray background, and high priority alarms could have a red background. By combining the foreground and background colors, you can create a very effective display. For example, white text on a red background makes locating priority High alarms very easy.
When you insert an Alarm Analysis object into a display, the default threshold is automatically loaded and enabled. You can create a new threshold by using the Save As function, or you can load a different pre-configured threshold with the Load function. The default threshold for the Alarm Analysis object is set on the Component Preferences dialog box, where you can also make changes to the default threshold, if required.
