Packet Input/Output

This example shows how to transfer data through UDP communication protocol using binary encoding. The model sends data within one computer, from one UDP port to another. You can modify the model to communicate between two computers by splitting this model into its send and receive parts and running the models on two computers. The yellow blocks are used to send the data, the blue blocks are used to receive the data. Then, please enter the host names or IP addresses of the two computers into the appropriate fields in the Board Setup dialog.

Run Model in Normal Mode

  1. To switch to normal mode if needed, on the Simulation tab, select Normal mode.

  2. To start the real-time execution, on the Simulation tab, click Run.

Run Model in External Mode

To start the real-time execution in external mode, on the Desktop Real-Time tab, click Run in Real-Time. The model builds, connect to external mode, and starts.

Open the Model

These commands open the model and suppress warning about board not installed.

w = warning('off', 'sldrt:blkgui:boardnotonlist');

Close Open Scopes
