Enable External Mode for ROS Toolbox Models

External mode enables Simulink^® on your host computer to communicate with a deployed model on your robotics hardware during runtime. External mode allows you to tune block mask parameters and to visualize signals on your model while your model is running. For ROS Toolbox, deployed models are ROS nodes running on the target hardware that communicates with Simulink over TCP/IP.

To use external mode with ROS Toolbox models:

1. On the Apps tab, under Control Systems, click Robot Operating System (ROS).

2. In the Robot Operating System (ROS) dialog box that opens up, select Robot Operating System (ROS) from the ROS Network drop-down. This opens up the ROS tab in the toolstrip which shows the specified ROS Network in the Connect section.

3. In the Connect section, specify Deploy To option as Remote Device, from the drop-down. To configure the remote device details such as IP address and user details, select Manage Remote Device from the drop-down.

4. In the Prepare section, click Hardware Settings to open the model configuration parameters dialog box. In Target Hardware Resources, set the External mode parameters. Click OK.

5. In the model, set the Simulation mode to External for the model.

6. Run the model.

Your model connects to the Device Address specified in the Connect to ROS Device dialog box which is used to connect to your ROS device when deploying the model.

To configure signal monitoring and data archiving, go to the Apps tab and select External Mode Control Panel. You can also connect to the target program and start and stop execution of the model code.
