    The Notifications pane appears.
    The alarm notifications that appear in the Notifications pane are displayed based on the scenarios described in the following table.
    ScenarioAlarm Notification Behavior
    When the variable value violates an alarm condition for the first time.
    • A new alarm event is added for the alarm condition and the notification for the alarm condition is added to the Notifications pane.
    • The time when the alarm was added appears in the Start field. The date and time is displayed in the format is mm/dd hh:mm (Example: 09/29 09:20) or dd/mm hh:mm (Example: 29/09 09:20) based on the localization settings. When you hover over the date and time, the complete date and time appears on the tool tip in the format mm/dd/yyyy hh:mm:ss or dd/mm/yyyy hh:mm:ss based on the localization settings.
    • The End field appears blank for the open alarm.
    When the variable value is within the specification limits for all current and past events. The alarm event is deleted for the alarm condition, and the alarm notification is removed from the Notifications pane.
    When the variable value is modified to be within the specification limits for an event. However, any past or current events still include variable value violating the alarm condition. The time when the variable value was modified to be within the specification limits for an event appears in the End field. The date and time is displayed in the format is mm/dd hh:mm (Example: 09/29 09:20) or dd/mm hh:mm (Example: 29/09 09:20) based on the localization settings. When you hover over the date and time, the complete date and time appears on the tool tip in the format mm/dd/yyyy hh:mm:ss or dd/mm/yyyy hh:mm:ss based on the localization settings.The number of batches for which the alarm notification is still unacknowledged also appears.
    When a closed alarm event is reopened because the variable value was modified to a value that violates the alarm condition.
    • The closed alarm event is reopened for the alarm condition and the notification for the alarm condition appears in the Notifications pane.
    • The time when the alarm was added initially appears in the Start time option. The date and time is displayed in the format is mm/dd hh:mm (Example: 09/29 09:20) or dd/mm hh:mm (Example: 29/09 09:20) based on the localization settings. When you hover over the date and time, the complete date and time appears on the tool tip in the format mm/dd/yyyy hh:mm:ss or dd/mm/yyyy hh:mm:ss based on the localization settings.

  3. In a notification, select Show More.
    A detailed view of the notification appears, displaying a sparkline (a line chart without axes or coordinates) between the two dash lines that indicate upper and lower reject or warning limits of the variable value as configured in the alarm template. If there is a product change associated with the variable, the dash lines appear modified, indicating the upper and lower reject or warning limits of the variable value for the new product.
    By default, the sparkline plots a line graph based on the variable values trending four hours before and after the variable value on which the alarm was created. The actual variable value on which the alarm was triggered is indicated by a red dot.
    Note: You set the duration of the time range for the variable value in the BorderDuration site parameter for Alarms in Plant Applications Administrator. By default, the value of the BorderDuration site parameter is set to 240 minutes.
    Tip: In the Notifications pane, select Expand All to access the detailed view of all notifications. You can then select Collapse All to go back to the summary view of all notifications.
