About this task

The Engineering View allows a detailed examination of the integration items. Although mapped devices and points are shown, the Engineering View also provides details for objects that are not mapped into the Integration.

Note: Only viewing and commanding are applicable in the Engineering View; there is no option for mapping.

Relearn uses Auto Discovery and requires that the network engine be online with the LonWorks network of devices being discovered.

To add Integrated LonWorks objects to the Integration Tree using Relearn:


  1. Select the LonWorks Integration object in the Navigation tree.
  2. Click the Engineering tab, and then click the Relearn button that appears underneath the Summary tab.

  3. The discovery begins automatically and finds all new LonWorks devices on the network. The Relearn screen appears. The Restart button repeats the discovery process.
    Note: Discovery by Relearn removes from the Integration Tree devices that are unmapped and not communicating with the network engine. After discovery, the newly found devices appear in the Integration Tree in the Engineering view.

  4. When discovery is complete, close the Relearn screen.
