Board io device (dictionary item)
For automation interface information about a Board IO Device, see Board io device (automation interface).
A Board IO Device is a piece of hardware that handles inputs to and outputs from a Board.
You can create a Board IO Device through the context menu of a Board Type, and through the Board IO Device tab of a Board Type's Property Pages.
When used on a System Architecture Diagram, a Board IO Device's notation is as follows:
In the Modeler panes, a short-cut symbol on the Board IO Device's icon indicates that the item is a stub. For more information, see ‘Stubs.
Note that you cannot link a Board IO Device directly to a Board. A Board uses the Board IO Devices from a linked Board Type.
To see how a Board IO Device is used when defining a Board, see .

If you select the Proprietary\Board IO Devices folder in the Dictionary pane, the Contents pane displays the following information about each Board IO Device in the model: Memory Start Address, Memory End Address, Memory Size, Port Address and IRQ.
The following sections provide information about how a Board IO Device is used in the model. For more information about a property, item, model part or diagram, click it.

Comment
Constraint
Dependency - The Dependency is owned jointly by the Board IO 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 Board IO 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.
Point-to-point Connection - The Point-to-point Connection is owned jointly by the Board IO 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.
