Creazione di maschere del blocco

Creare un aspetto personalizzato, creare un'interfaccia definita dall'utente, incapsulare la logica e nascondere i dati per i sottosistemi e i blocchi personalizzati

Simulink^® consente di creare maschere del blocco. Una maschera è un'interfaccia utente personalizzata per un blocco.

Mascherando un blocco, si incapsula il diagramma del blocco in modo da avere una propria finestra di dialogo dei parametri con una propria descrizione del blocco, il prompt dei parametri e i testi di supporto.

È possibile mascherare un blocco personalizzato indipendente che può essere riutilizzato come blocco unico, come quelli definiti in Simulink.

Per informazioni sulla creazione di una maschera del blocco, vedere Create a Simple Mask.

Promote Block Parameters on a Mask

Blocks and subsystems can have multiple parameters associated with them. Block masks allow you to expose one or more of these parameters while hiding others from view. You can promote any underlying parameter of a block either to a block mask or to a subsystem mask. For any subsystem, you have a single view of all the nested blocks, the block parameters, and internal parameters. You can click on any node to access any promotable parameter within the nested blocks. By promoting parameters from the block dialog box to the mask you can:
