24 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 with power line repeating
enabled. Standalone 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 that a message must
travel on the PL-20 or RF channel from the Segment Controller to one or more
repeating devices (luminaires or CRD 3000 Street Light Bridge modules) before
reaching the target device (a luminaire or a CRD 3000 Street Light Bridge
module).
In standalone mode, the Segment Controller controls the network management
commands sent to the devices attached to its channel. In this 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 Segment Controller Web pages,
perform the following steps:
1. Open the Segment Controller Web pages, as described in Chapter 3 of the
i.LON SmartServer User’s Guide.
2. Click the Net network to display the Lon Network Property page.
3. From the Setup tab, select Standalone.
4. Click Submit. A dialog appears informing you that the Segment
Controller is switching to standalone mode.
It could take several minutes for the Segment Controller to switch to standalone
mode. After the Segment Controller has switched to standalone mode, the dialog
closes and you can continue preparing your Segment Controller 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
(luminaires and CRD 3000 Street Light Bridge modules).
