External connector (dictionary item)
For automation interface information about an External Connector, see External connector (automation interface).
An External Connector is used to link an Actor with an Interface Device or Subsystem on a System Architecture Diagram.
You create an External Connector through the System Architecture Diagram. Modeler creates an External Connector when you add a Link between an Actor and an Interface Device or Subsystem.
When used on a System Architecture Diagram, an External Connector's notation is as follows:
The direction of an External Connection is represented as follows:
In the Modeler panes, a short-cut symbol on the External Connector's icon indicates that the item is a stub.
The access permissions you have to an External Connector are determined by the access permissions you have to the source item.
The following sections provide information about how an External Connector is used in the model. For more information about a property, item, model part or diagram, click it.
Properties
In addition to the standard properties, an External Connector has these properties:
• Constraints
• Direction (Flow Direction through the automation interface) — Specifies None, Start-End, End-Start or Bi-directional.
Owned by
Actor
Interface Device
Subsystem
* 
An External Connector is owned jointly by the Actor and the Interface Device or Subsystem it links, that is, if either item is deleted the External Connector is deleted as well. The access permissions you have to an External Connector are determined by the access permissions you have to the source item.
Owns
Comment
Dependency — The Dependency is owned jointly by the External Connector and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.
