The plant hierarchy name and asset folder names come directly from the Asset Server and cannot be renamed. They can be deleted. If you delete a plant hierarchy or asset folder from the hierarchy in the DeltaV Explorer, all subordinate objects are also deleted. Be aware that if an asset is deleted from the Explorer hierarchy but remains configured on the external asset server, it will show up again in the DeltaV Explorer when the configuration is resynchronized unless it is deleted during synchronization. Configuration options for the plant hierarchy and asset folders include adding a description and associating alarms and events with a DeltaV plant area. When alarms and events are associated with a plant area from the plant hierarchy or asset folders levels, all subordinate asset alarms are included in the association. This enables large groups of asset alarms to be easily assigned to a single area. However, an area can also be associated with a lower level asset folder. In addition, an individual asset can be associated with a control module for area association. Association at a lower level takes precedence over a higher level.
