About this task

Add trend, totalization, alarm, load, and averaging extensions to increase the functionality of a field device or field point object.

After creating a field device object or a field point object, the Extension Wizard automatically starts (skip to Step 3).


  1. Select an object.
  2. On the Action menu, select Show Extensions. The Extension Wizard starts.
  3. Click New in the row next to the desired type of extension. Follow the prompts on the Wizard that appears. See Adding a Trend Extension, Adding a Totalization Extension, or Adding an Alarm Extension for more information.
  4. Follow the prompts to configure the extension and click Finish when done. The Extension Wizard appears with the new extension listed in the appropriate row.
  5. Click Done after adding the needed extensions. If the Extension Wizard launches automatically after creating the new field device object, the Field Device Extension screen opens next.
  6. Add field points under the newly created controller object by clicking New in the Field Points panel of the Field Device Extension Wizard. See Manually adding BACnet MS/TP (Field Bus) Field Devices (online or offline) for instructions on adding BACnet MS/TP points.
