The Canvas Simulator can operate a project with an Alarm Summary object that displays up to 150 alarms reliably. Likewise, a physical Xpanel can reliably do the same with up to 1,000 alarms. The operating speeds of both the Simulator and a physical Xpanel will depreciate with the creation of more alarms. Click Insert > Alarm Summary,or the Insert Alarm Summary icon in the toolbar, and click and drag on the page to bring up the Alarm Summary object as shown to the right:

The Basic Properties window allows changing the displayed content and formatting within the object. The object’s name will show up in place of Basic Properties, as displayed to the right:

The Appearance pane enables the use of colors and selections to alter visible characteristics.

The Transform tab provides adjustable properties that reshape or move the object.

There are currently no applicable actions for the Alarm Summary object. This is intended, and there are no plans to add this capability.

Notifications that a user set up for an alarm action or label will display as a pop-up at the bottom of an Alarm Summary object when triggered. If clicked, the expand button on the right side of the pop-up will bring up a screen showing all notifications. An example of a notification in an Alarm Summary object during runtime is shown on the right:

When running the program, the user can select the Label Filter option in the Alarm Summary to display the alarms with a specific label. Multiple labels may be applied simultaneously. All active, cleared, and all active acknowledged alarms with the selected labels will be displayed in the active tab of the Alarm Summary. If an active alarm has more than one label, that alarm will be displayed when any of its labels are selected. The same can be done in the historical tab for the historical with active, cleared, acknowledged, and shelved alarms.

The user can acknowledge alarms to confirm that they have been seen and to trigger Acknowledge actions. If a cleared alarm is acknowledged, it will move from Active to Historical. Otherwise, any alarm will stay on the page until deleted. Users can check or uncheck the boxes for “Active”, “Cleared”, “Active, Ack.”, and “Cleared, Ack” to show or hide certain statuses.

The Historical Alarms tab creates a new record whenever an alarm status changes. The user can check a past alarm along with the status it was changed to, the time it was changed, and the value it had when it was changed. The logged alarms are filterable and deletable for better organization.
