56 Managing a Street Lighting Network
The direct communication devices (proxies that can directly receive
messages from the Segment Controller without any repeating) are listed
in the Direct Communication column (in the example above, the
Segment Controller can reach both Lamp 1 and SLB 1 directly). The
direct communication devices can relay messages to proxies and target
devices further down the power line (in the example above, SLB 2 and
Lamp 2).
The proxies and target devices are listed under the Proxy Zone columns
(in the example above, SLB 2 is Proxy Zone 1, and Lamp 2 is in Proxy
Zone 2). The last repeating device in the chain before the target device is
referred to as the “proxy agent”.
For example, if a target device uses four hops to receive a message, you
would observe:
a. The proxy in the repeating chain that directly communicates with
the Segment Controller is listed in the Direct Communication
column.
b. The next proxy in the repeating chain, which does not have direct
communication with the Segment Controller, is listed in the
Proxy Zone 1 column.
c. The proxy that can directly communicate with the target device
(the proxy agent) is listed in the Proxy Zone 2 column.
d. The target device is listed in the Proxy Zone 3 column.
If a target device requires the maximum of eight hops, you can scroll to
the right to Proxy Zone 7 column to view the target device and its
repeating chain to the left.
4. You can display statistics related to the power line signal at the hop
between a device and its proxy by selecting the following checkboxes at
the top of the Web page (you can view all the statistics by clicking the
Display All Standard Information checkbox).
