Go to [libiec61850 GitHub page](https://github.com/mz-automation/libiec61850) to download the source code, follow the instructions on the project page to compile the source code, here is a demonstration of the compilation and installation on Ubuntu systems.

```sh
$ cd libiec61850
$ mkdir build
$ cd build
$ cmake .. && make -j4
$ cd sudo ./examples/server_example_61400_25/server_example_61400_25
```

## Configure Neuron

1. Adding an IEC61850 device to the Neuron southbound device management;

2. Change the **Device IP Address** to the IP address of the **server_example_61400_25** server listening in the device configuration.

3. Change the **Device Port** to **server_example_61400_25** in the device configuration for the port the server is listening on.

4. Leave the other configuration parameters as default and submit the settings form.

6. Add **Group**, add from test **Tag**.
