Messages

Send messages to pass data between charts

Send, receive, and forward messages that carry data to communicate between Stateflow^® charts and other Simulink^® and SimEvents^® components. Unlike events, messages are queued until the receiving component can process them. For more information about using messages in Simulink, see Simulink Messages Overview (Simulink).
