Alarm indicators and alarm flags are defined using Global conditions, and are included within a composition to be made visible to the user via the Presentation Options dialog box.

Given below is the code snippet for the Global condition that defines an alarm indicator.

Alarm indicators can be displayed on a Composite Genie and/or the related equipment associated with it (shown below).

Given below is the code snippet for the Global condition that defines an alarm flag and its positioning.

Alarm flags need to be included in a composition within the Alarm Indicators for them to displayed in the Presentation Options dialog box.

The triggers are used to define FlagStyle conditionally. When none of the When conditions is satisfied, the FlagStyle is set to the fallback value specified by <AlarmIndicator FlagStyle="<fallback_value>"> element.

You can also set up the FlagStyle attribute within <AlarmIndicator> without Triggers. The FlagStyle attribute is "Hidden" by default if it is not specified.

An alarm flag can be positioned at one of the following locations:

  • None: Alarm flag is not displayed. This is the default.

  • Top Left

  • Top Center

  • Top Right

  • Center Left

  • Center Right

  • Bottom Left

  • Bottom Center

  • Bottom Right

    Note: If you change the size of an alarm flag and run the Update Pages command, the Composite Genie instances are re-sized to accommodate the size of the alarm flag.
