Alternative Configurations of Send Block:
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 and Message Send blocks are identical blocks.

Ports

Input

Port_Enable — External enable signal

scalar

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

Port_1 — Input signal

scalar | vector | matrix

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.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | enumerated | bus | fixed point

Output

Port_1 — Output message

scalar | vector | matrix

The block outputs a message with constant priority 20.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | enumerated | bus | fixed point

Parameters

Show enable port — Display the enable port

off (default) | on

Select this check box to display enable port. 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.

Programmatic Use

Block Parameter: ShowEnablePort

Type: character vector

Values: 'on' | 'off'

Default: 'off'

Block Characteristics

Data Types	Boolean | bus | double | enumerated | fixed point | integer | single | string
Direct Feedthrough	no
Multidimensional Signals	yes
Variable-Size Signals	no
Zero-Crossing Detection	no

Alternative Configurations

Message Send — Create and send message

The Message Send block differs from the Send block in name only.
