Messages

Establish message-based communication between Simulink® model components

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.

To learn more about Simulink messages, see Simulink Messages Overview.
