Mensajes
R2026aLos mensajes se utilizan para modelar la comunicación entre los componentes de Simulink con el fin de integrar el sistema. Se pueden utilizar mensajes para establecer la comunicación en un modelo de composición cuyos componentes ejecutan un conjunto definido de funcionalidades con límites de I/O.
La comunicación basada en mensajes entre componentes de software es necesaria en las arquitecturas de sistemas de control en las que las arquitecturas centralizadas se sustituyen por arquitecturas distribuidas debido a la complejidad del sistema. Un mensaje es un útil artefacto de modelado que combina eventos con datos relacionados. Utilice bloques de mensajes para gestionar la producción, el consumo y el almacenamiento de mensajes.
