Add nE2 Device Extension in Niagara
The nE2 device extension is only required to program or commission an nE2 device.
It is not required for integration of a nE2 devices' points over BACnet in a Niagara station.
Therefore, when programming is finished, the nE2 device extension can be removed, to reduce the load on a station.
- In Workbench, navigate to the nE2Link module in the Palette sidebar.
- Open the Programming folder in the palette and locate the nE2DeviceExt.

The nE2DeviceExt has sub-components, but they will only be used once the extension is applied to
an nE2 device in the station:
- Poll Scheduler: manages communication between the Niagara Framework and the nano EDGE ENGINE controller;
- Software Manager: allows for managing libraries on the controller;
- Libraries: by default, the container is empty and requires a real-time connection to upload
the libraries available on the device.
Once connected, the device's library will be populated with data from the device
and load all the libraries available on the nano EDGE ENGINE device;

- Add nE2DeviceExt to Device:
Drag the nE2DeviceExt extension from the nE2Link palette
and drop it onto the BACnet or Modbus device that represents the nE2 controller in the Niagara station.

In nano EDGE ENGINE devices, such as the RAC18-IP, the native BACnet support guarantees that it can be discovered on the BACnet IP network out of the box.
- Accept or change the predefined name for the nE2DeviceExt.

The nE2 device extension is now ready and can be used to connect to the device for programming or commissioning
