Send TCP/IP message from server

Add-On Required: This feature requires the Simulink Support Package for Arduino Hardware add-on.


Simulink Support Package for Arduino Hardware/Ethernet Shield

  • TCP/IP Send block


Send TCP/IP messages from a server over a wired network.

Use this block when your model has the following requirements:

  • Reliable message transmission

  • Unchanged message order

  • Acceptable compromise on the transmission speed

The TCP/IP server created by this block can accept four socket connections on the Arduino® board.

This block input accepts uint8 values.

During simulations without the hardware, this block does nothing.


Server port

Enter the port number through which you want the TCP/IP server to send the messages. The server port numbers range from 0 to 65535.
