+Service Interface Examples
+==========================
+
+Before running these examples, ensure that to :ref:`start the vcan0 interface <quick-start-setup-can-controller>`. 
+You can find these examples in the ``canopen_test`` package.
+
+Proxy Driver Examples
+---------------------
+A proxy driver provides a simple way to forward CANopen functionalities for a specific device using ROS2 services and messages. For more details on the proxy driver, see :doc:`../user-guide/proxy-driver`.
+
+Configuring ``bus.yaml``
+~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration for the proxy driver is specified in the ``bus.yaml`` file. Here's an example configuration:
+
+.. code-block:: yaml
+    
+    options:
+        dcf_path: "@BUS_CONFIG_PATH@"
+
+    master:
+        node_id: 1
+        driver: "ros2_canopen::MasterDriver"
+        package: "canopen_master_driver"
+
+    defaults:
+        dcf: "simple.eds"
+        driver: "ros2_canopen::ProxyDriver"
+        package: "canopen_proxy_driver"
+        polling: true
+        period: 10
+
+    nodes:
+        proxy_device_1:
+            node_id: 2
+        proxy_device_2:
+            node_id: 3
+
+For further details about the configuration, refer to :doc:`../user-guide/configuration`. Additionally, add ``cogen_dcf(simple)`` in the *CMakeLists.txt* file to generate the necessary artifacts for the proxy driver.
+
+Running the Proxy Driver Examples
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+To launch the proxy driver setup, use the following command:
+
+.. code-block:: bash
+
+    $ ros2 launch canopen_tests proxy_setup.launch.py
+
+Verify that all services are available by running the ROS2 topic and service list commands. To conduct a test:
+
+.. code-block:: bash
+
+    $ ros2 topic pub /proxy_device_1/tpdo canopen_interfaces/msg/COData "{ index: 0x4000, subindex: 0, data: 200 }"
+
+Check the output by running:
+
+.. code-block:: bash
+
+    $ ros2 topic echo /proxy_device_1/rpdo
+
+.. note::
+
+    These examples use a fake slave device. Running on actual hardware may yield different results. 
+    Always refer to the device's documentation for specific details.
