Messages are used to model communication between Simulink components for the purpose of system integration. You can use messages to establish communication in a composition model whose components perform a defined set of functionalities with I/O boundaries.
Message-based communication between software components is necessary in control system architectures where centralized architectures are replaced by distributed architectures due to system complexity. A message is a useful modeling artifact that combines events with related data. Use message blocks to manage the production, consumption, and storage of messages.

Overview of the message-based communication workflow.
This example shows how to send, receive, and visualize messages.
This example shows how to model message-based communication between software components that run in different applications.
This example shows how to send and receive messages carrying bus data between model components.
This example shows how to synchronize execution with data availability in message-based systems.
This example shows how to use message communication within a distributed system where the controller manages multiple incoming messages from different senders in an iterative manner and sends messages to communicate commands to the different receivers.
This example shows how to use a Queue block to store and queue messages.
This example shows how to create common communication patterns using SimEvents®.
