UDP 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:
SoC Blockset Support Package for AMD FPGA and SoC Devices

Description

Add-On Required: This feature requires the SoC Blockset Support Package for AMD FPGA and SoC Devices add-on.

The UDP Send block transmits an input vector as a user datagram protocol (UDP) message over an IP network port.

Examples

Ports

Input

Port_1 — Input data signal

N-by-1 array

Input signal of messages to be sent to the remote IP address and port.

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

Parameters

To edit block parameters interactively, use the Property Inspector. From the Simulink^® Toolstrip, on the Simulation tab, in the Prepare gallery, select Property Inspector.

To set the block parameter value programmatically, use the set_param (Simulink) function.

To get the block parameter value programmatically, use the get_param (Simulink) function.

IP address — IP address

'255.255.255.255' (default) | character vector

Specify the IP address which the block sends the message. To broadcast the UDP message, retain the default value '255.255.255.255'.

Programmatic Use

Block Parameter: localURL

Remote IP port — Remote IP port

25000 (default) | 1–65535

Specify the IP port where the block sends the message.

Programmatic Use

Block Parameter: remoteURL

Local IP port source — Local IP port source

Assign automatically (default) | Specify via dialog

To let the system automatically assign the port number, select Assign automatically. To specify the IP port number using the Local IP port parameter, select Specify via dialog.

Programmatic Use

Block Parameter: localPortSource

Local IP port — Local IP port

-1 (default) | 1–65535

Specify the IP port number from which the block sends the message. If the receiving address expects messages from a particular port number, enter that number here.

Programmatic Use

Block Parameter: localPort

Programmatic Use: Add Block

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

"zynqlib/UDP Send"

Example: add_block("zynqlib/UDP Send","myModel/myBlock",MakeNameUnique="on")
