Message Send

Description

The Send block reads the value of an input signal, and sends a message that carries this value. In message-based communication, a message is a discrete-item of interest that carry data of any type that Simulink supports. Send andMessage Send blocks are identical blocks.

Examples

Ports

Input

expand all

Input port to enable the block to send a message. For any input value that is greater than 0 send is enabled. For any value less than or equal to 0, the send is disabled.

Dependencies

To enable this port, select the box labeled Show enable port.

Data Types: double

This block accepts inputs of any type that Simulink® supports, including enumerated types and converts the input signal to a message. For more information, see Data Types Supported by Simulink.

Output
