Messages & Events
R2026bUtilice bloques de la biblioteca Messages & Events para modelar comunicaciones basadas en mensajes entre componentes. La comunicación basada en mensajes es necesaria en las arquitecturas de sistemas de control distribuidas en las que la complejidad del sistema no permite aplicar un enfoque centralizado. Un mensaje combina un evento con datos relacionados y permite que los componentes se comuniquen sin necesidad de una ejecución simultánea.
Para añadir bloques de esta biblioteca al modelo, consulte Add Blocks to Models.
Bloques

 | Message Merge | Combine message paths |
 | Message Triggered Subsystem | Subsystem whose execution is controlled by message input (Desde R2022a) |
 | Queue | Enqueue messages and entities |
 | Receive | Receive messages |
 | Send | Create and send message |
 | Sequence Viewer | Display messages, events, states, transitions, and functions between blocks during simulation |

Schedule Time Hits and Function-Call Events During Simulation
Use the Hit Scheduler block to schedule time hits and function-call events based on the runtime behavior of a system. The model in this example represents a traffic camera system that captures images of speeding vehicles. The Hit Scheduler block schedules time hits for the simulation based on runtime computations that determine when the camera should capture an image.
Model Effect of Temperature and Jitter on Crystal Oscillation Frequency
Use the Hit Scheduler block to model temperature drift and jitter in crystal oscillator frequency.
Model Conveyor Belt as Cyber-Physical System
Model a variable-speed conveyor belt as a cyber-physical system by combining continuous-time, discrete-event, and finite-state modeling techniques. The model in this example integrates the modeling techniques required to represent the cyber-physical system into a single simulation environment by using Simulink®, SimEvents®, and Stateflow®.
