TCP/IP Send block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink Coder Support Package for BeagleBone Blue Hardware / Communication
Raspberry Pi Blockset / Network
Simulink Support Package for Android Devices / Communication
Simulink Support Package for LEGO MINDSTORMS EV3 Hardware

Description

Add-On Required: This feature requires one of these add-ons.

• Simulink Support Package for LEGO MINDSTORMS EV3 Hardware
• Simulink Support Package for Android Devices

Send data to a remote host/another hardware board over the network. You can set the connection mode of the block as a server or a client. When you set connection mode as TCP/IP client, you must provide the remote address and the remote IP port of the TCP/IP server to which you have to send the data. When you set the block as a TCP/IP server, you must provide the local IP port of the TCP/IP server. This IP port acts as the listening port of the TCP/IP server.

Examples

Ports

Input

Port1 — Input port to accept data

[Nx1] array

The block accepts data as an [Nx1] array.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean

Parameters

Main Tab

Connection mode — Option to set the block as client or server

Client (default) | Server

Select this option to set the block as TCP/IP client or TCP/IP server.

Local IP port — Local port acting as the listening port of the server

25000 (default) | scalar

Enter the local port number which acts as the listening port of the TCP/IP server. This parameter appears only when you set the Connection mode to Server.

Remote IP address — Remote address of the server to which to send the data

127.0.0.1 (default) | scalar

Enter the remote server address to which to send the data. This parameter appears only when you set the Connection mode to Client.

Remote IP port — Remote port of the server to which to send data

25000 (default) | scalar

Enter the remote server port. This parameter appears only when you set the Connection mode to Client.

Advanced Tab

Manually specify local IP port — Manually specify the number of the local IP port

off (default) | on

Allow manual specification of local IP port from which to send data. This parameter appears only when you set the Connection mode to Client.

Local IP port — Local port from which to send the data

25000 (default) | scalar

Enter the local port of the client to send data. This parameter appears only when you set the Connection mode to Client and select the check box Manually specify local IP port.

Wait until previous packet transmitted — Option to set for the block to wait for the data to be sent

off (default) | on

Select this option to specify for block to wait for the current data to be sent. Selecting this check box enables the ‘blocking mode’.

Timeout in seconds — Time to wait until the data is sent

0.1 (default) | scalar

Specify the time the block waits for the data to be sent during each simulation time step. This field is unavailable, if you have not selected Wait until previous packet transmitted parameter. Enter inf value in this parameter, if you want the block to wait indefinitely until it sends the data.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
