Version 3.5.1.21 of Doors.NET supports what is known in the industry as Pop-Up Alerts.

When a hardware object (input, reader, controller, etc) is configured with this setting it will cause the Doors.NET user interface to become the 'Top-Most' application and the alerts grid will also come to the front (even if the Alerts grid has been closed).This feature works well with Sound Alerts for a greater level of event notification.

This article explains how to setup an input on a 4x4 as a Pop-Up Alert trigger when it is activated.

Setup Procedure

• Got to Setup >> Hardware Setup >> All.
• Add an NXT 4x4 module to one of the controller's buses.

• Expand the 4x4 inputs and rename that one that will be used as the pop-up event trigger (the alert will be generated when the input goes active).
• Save.

• Go to Setup >> Device Types.

• Click the Add Device Type button and rename the new device type.
• Select Make Active Window (Top Most) and Must Confirm.
• Save.

• Next, go to Setup >> Filters.

• Click the Add Filter button.
• Rename and then save the new filter.
• Click the Messages tab and select the specific Monitor Point - Alarm and Monitor Point - Secure message types.
• Save.
• Go to the Acknowledge tab and place a tick against Monitor Point - Alarm.

• Save the filter settings once more.

• Now, you would need to go to the hardware tree again and select the input on the 4x4 which you have dedicated.
• Ensure Advanced View is enabled so you can see all the hardware properties.

• Scroll down the input properties and locate Monitoring (near the bottom of the grid).
• Apply the Filter and Device Type that you recently created.
• Set Require Acknowledgment to Yes.

• Save the input settings.
• Activate the input while Doors.NET is minimized and you will see the user interface become the top-most application.
• Close down the alerts grid and just have the Hardware Setup page open, for example. The Alerts page will then automatically open when the alert is generated.
