28 Setting Up the Segment Controller
Placing the Segment Controller in Standalone
Mode
A street lighting network is a power line repeating network, which requires that
the Segment Controller operate in standalone mode. This mode allows the
Segment Controller to operate as the exclusive network manager of the system,
and to establish and maintain the appropriate repeating chains. A
repeating
chain
is the path a message must travel on the PL-20 or RF channel from the
Segment Controller to one or more repeating devices (luminaires or Street Light
Bridge modules) before reaching the target device (a luminaire or a Street Light
Bridge module).
In standalone mode, the Segment Controller controls the network management
commands sent to the devices attached to its channel (note that for a network
operating in LNS mode, LNS would handle these commands). In standalone
mode, the Segment Controller can directly download the application image file to
the devices and commission, set the application state (online/offline), wink, test,
and reset the devices attached to its channel.
Placing a Network in Standalone Mode
To set a network to standalone mode using the SmartServer Web pages, perform
the following steps:
1. Open the SmartServer Web pages, as described in Chapter 3 of the i.LON
SmartServer 2.0 User’s Guide
.
2. Click the Net network to display the Lon Display Property page.
3. From the Setup tab, select Standalone.
4. Click Submit. A dialog appears informing you that the SmartServer is
switching to standalone mode.
It could take several minutes for the SmartServer to switch to standalone mode.
After the SmartServer has switched to standalone mode, the dialog closes and
you can continue preparing your SmartServer for the network installation.
Network Limitations in Standalone Mode
Managing a power line repeating network in standalone mode has the following
restrictions:
• Network is limited to a maximum of approximately 200 devices.
• Network is limited to a single channel.
