Interface device (dictionary item)
For automation interface information about an Interface Device, see Interface device concurrency model.
An interface device is a piece of hardware that interacts with an Actor, another Subsystem or a different system entirely. Typically, the internals of an Interface Device are of no interest. If this is not the case, then a Subsystem should be used instead.
You can create an Interface Device through the context menu of a Package: right-click the Package, point to New, point to Proprietary, point to Concurrency, and then click Interface Device. In addition, you can create an Interface Device through a Concurrency Diagram, Sequence Diagram and System Architecture Diagram.
In addition, you can also create an Interface Device by copying an existing Interface Device. Modeler copies the Interface Device's links. For more information, see Copying items.
When used on a diagram, an Interface Device's notation is as follows:
In the Modeler panes, a short-cut symbol on the Interface Device's icon indicates that the item is a stub.
The following sections provide information about how an Interface Device 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 Interface Device has these properties:
• Number of Instances
• Visibility
Owned by
Model
Package
Owns
Comment
Constraint
Dependency —The Dependency is owned jointly by the Interface Device and the other associated item. The access permissions you have to a Dependency are determined by the access permissions of the dependent item.
Drop —The Drop is owned jointly by the Interface Device and the associated Multidrop Bus. The access permissions you have to a Drop are determined by the access permissions you have to the source item.
External Connector —The External Connector is owned jointly by the Interface Device and the associated Actor. The access permissions you have to an External Connector are determined by the access permissions you have to the source item.
Point-to-point Connection —The Point-to-point Connection is owned jointly by the Interface Device and the associated item. The access permissions you have to a Point to Point Connection are determined by the access permissions you have to the source item.

Can be linked to these dictionary items
In addition to the owning Package or Model, an Interface Device can be linked to the following items.
Interface Device Type —The linked Interface Device Type specifies technical features of the Interface Device.
Stereotype
Subsystem —Note that an interface Device cannot be linked to both a Package and a Subsystem.
