offsite during the network design phase, yet it provides the flexibility to change the network
configuration while onsite. This scenario is often used for building and industrial automation systems,
in which the original network design closely matches the actual installation.
With an ad-hoc system, you both design and install the network onsite. Network configuration data is
incrementally loaded into the physical devices as you add, configure, and install more devices with an
OpenLNS tool or the SmartServer. If you use the SmartServer to install an ad-hoc system, you can add
and install the devices either using the OpenLNS tree provided that an OpenLNS Server is attached to
the LAN and the LNS proxy is enabled on it, or you can use the SmartServer tree with the SmartServer
running in standalone mode. The ad-hoc system provides installers with the flexibility to make design
decisions onsite. It is most appropriate for small, simple networks in which the details of the system to
be installed are not known prior to arriving onsite.
You can also install a network under a combination of both engineered and ad-hoc system scenarios.
For example, you can partially design a network offsite, install the devices onsite, and then
incrementally add devices to the network design onsite and install them.
The following sections describe the steps required to install a network:
1. Acquiring the Neuron ID of the devices to be installed.
2. Selecting the devices to be installed.
3. Installing the devices using Smart Network Management.
Acquiring the Neuron ID
In order to install a device, you must first acquire its Neuron ID. The Neuron ID is a unique 48-bit
number manufactured into the Neuron chip of the device. Acquiring the Neuron ID broadcasts the
device’s Neuron ID and program ID over the network so that a logical address (Subnet/Node ID) can
be assigned to the device.
You can acquire the Neuron ID of a device automatically using device discovery or manually by either
pressing a service pin on the device, manually entering a 12-digit hex string, or scanning in a bar code
on the device.
Automatically Acquiring the Neuron ID
You can automatically acquire the Neuron ID of uncommissioned L ON W ORKS device using device
discovery. You can do this from the Overview – Devices Web page or from the Setup – LON Device
Driver Web page.
Automatically Acquiring the Neuron ID with Overview - Devices Web Page
To automatically acquire the Neuron ID of a L ON W ORKS from the Overview – Devices Web page,
follow these steps:
1. Verify that the devices for which you are acquiring the Neuron IDs are uncommissioned.
2. Click Driver.
3. Right-click a network or channel, point to Overview, and then click Devices on the shortcut menu.
