Alarm Card Properties

Field Name	Description
View All Alarms by default (Disabling this option will display context based alarms)	This is a default setting to show all alarms irrespective of context when the page loads at runtime. If using the bread crumb widget along with the alarm card, then alarms are displayed according to the context. If an alarm contains an OPC UA tag that is not associated with a model property, then the source server of the tag is displayed in the alarm grid.
Asset Name (Optional Override)	Select your own asset to display alarms. The selected asset overrides the default asset name at runtime.
Data Source (default data source used to filter alarms on page load)	Select a data source to set as default for filtering alarms on page load at runtime.
Page Size - Number of alarms to display per page	Enter a number to specify the number of alarms that appear on a page at runtime. The maximum number of alarms you can display per page is 100.
Auto Hide Columns	Select to automatically hide the table columns if screen space is a constraint. Note: This option is enabled by default. To hide any of the other columns at runtime, you must clear the check box for this option.
Hide Acknowledge Column	Select to hide the Ack. column at runtime. This column contains the status to indicate whether the alarm is acknowledged in the HMI/SCADA system or not. A check mark in this column indicates that the alarm is acknowledged.
Hide Severity Column	Select to hide the Severity column at runtime. This column contains the icon that indicates the alarm severity status.
Hide Start Time Column	Select to hide the Start Time column at runtime. This column contains the start time and date for the alarm.
Hide Source Column	Select to hide the Source column at runtime. This column contains the tag associated to the alarm.
Hide Current Value Column	Select to hide the Current Value column at runtime. This column contains the query value such as whether the alarm is running or stopped.

Hide Property Column	Select to hide the Property column at runtime.
Hide Description Column	Select to hide the Description column at runtime.
Hide State Column	Select to hide the State column at runtime. This column contains the alarm's current status.
Hidden	Select this check box if you want to hide the plug-in. To show the hidden plug-in in Operations Hub new layout, go to Page Visuals and under Action column, select for the hidden plug-in. See Page Visuals Tab.

Alarm Card at Runtime

To acknowledge alarms, you must have the permission to do so in the supporting HMI/SCADA system.

Select to filter alarms based on specific conditions.

Each icon has a corresponding number to indicate the number of alarms currently active for that severity level. The alarm count in the banner shows the number of alarms per severity level for all assets in the model, whereas the alarm card displays the number of alarms per severity level for the selected context.

The severity of an alarm is based on the priorities set in the HMI/SCADA system (iFIX or CIMPLICITY). Each alarm icon is color-coded and contains a specific number of dots to indicate its severity level, as shown in this table.

Note: The alarm severity ranges are hard-coded in the application. Access the application.properties file to modify alarm severity ranges.

You can modify the property rank.ranks in C:\Program Files\GE\Operations Hub\webhmi-tomcat\webapps\alarm-microservice\WEB-INF\classes\application.properties and restart webHMI tomcat service.

Icon	Description
	Alarm is critical.
	Alarm is high priority.
	Alarm is medium priority.
	Alarm is low priority.

Alarm information is not displayed if data sources are disconnected. Select to get more information.

Note: Currently, if a data source is deleted from Operations Hub, the alarms configured to the deleted data source are still displayed at runtime. To clear such alarms, restart the data distributor service.
