Group Nodes
Important: Although hierarchies can be created and edited within the Group Service (GRP) by means of the GRP editor, this is strongly discouraged. Instead, use the Group Manager utility to create and edit group hierarchies. See Group Manager Utility for more information.
The GRP is a database service that stores group hierarchies based on facility and device attributes. Hierarchies are made up of nodes, each of which has its own set of properties and attributes. The GRP can store numerous hierarchies and their nodes, which are available to the various CygNet services they interact with, like the Point Service (PNT) and Facility Service (FAC).
Although the GRP powers group hierarchy creation and storage, the GRP is largely a behind-the-scenes service. Hierarchies stored in the GRP are typically created and edited using the Group Manager utility. Its interface is friendlier than the GRP editor and it enables both high- and low-level interaction with group hierarchies (and the GRP).
For maximum usefulness, use the Select Search feature in the GRP service pane in CygNet Explorer to expose, sort, and access information within the GRP. To do so, right-click in the GRP service pane and choose Select Search. Right-click in the GRP service pane to display the Select Search option. Multiple search property combinations appear.
The following table lists and describes the context menu options that display when you right-click in the Group service pane.
