Connectivity associations

Connectivity associations allow you to model the connectivity between two point features that are not coincident.

Conceptual view of connectivity associations in a network

In the diagram above, the transformer is connected to a connection point on an electric distribution line. This establishes a connection without the transformer needing to be coincident with the connection point. This connection represents the physical jumper between the transformer and the connection point in the real world.

About connectivity associations

A junction-junction connectivity association is used by two points and supports connectivity between terminals on device features. Junction-junction connectivity rules manage this type of association. You can define connectivity associations for device and junction feature classes in a domain network as long as network rules exist to support the association.

Two points that are not coincident can be offset from each other by x and y or z. The two point features maintain connectivity to each other through a connectivity association. For example, a transformer and a fuse are side by side. The fuse can also be located above a transformer and be connected. Some types of point features can be located in the same x, y, and z location. Points that cannot be coincident receive error features when the network topology is validated or enabled. To learn more, see Error feature management.

Device features with terminal configurations allow multiple connectivity associations as long as they are using unique terminals.

Point features that are located near each other in the field are offset from each other in a map. For example, an electrical fuse and a transformer may be only inches apart in the field. For clarity in a map, they are moved a couple feet apart to avoid the overlap of symbology. This is a common practice in utility maps where parts of a utility system can be quite dense. For example, in a substation.

Work with connectivity associations

Connectivity associations can be created using the Modify Associations pane. This is an interactive pane that allows you to select existing features in the map to establish connectivity associations between features.

Once connectivity associations are established, you can inspect the connectivity of features with connectivity associations using several methods. You can run a connected trace that will show you which features are connected. You can make connectivity associations visible on the map by using the View command. You can also generate a network diagram that will display connectivity associations in the diagram view.
