Send UDP message
The UDP Send block transmits an input vector as a UDP message over an IP network port.
Note: Some Simulink® blocks and .exe files built from models that contain those blocks require shared libraries, such as .dll files on Windows®. The UDP Send block requires networkdevice.dll. To meet this requirement, open the packNGo topic, and follow the example to package the code files for your model. The resulting compressed folder contains the .dll files that the model requires, including networkdevice.dll. To run this type of .exe file outside a MATLAB® environment, place the required .dll files in the same folder as the .exe file, or place them in a folder on the Windows system path.
Specify the IP address or hostname to which the block sends the message. To broadcast the UDP message, retain the default value, '127.0.0.1'.
Specify the port to which the block sends the message. The value defaults to 25000, but the values range from 1–65535.
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.
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.
