status in response to data point requests. After the Minimal Offline Time
elapses, the SmartServer sends a read/write request to one offline data
point. If the read/write request succeeds, the data point and its device
are marked online, and all cached read/write requests for the offline data
points on the device are executed. If you do not configure this property on
a power line repeating channel, it is set to 60 seconds.
5. Optionally, you can set the Use Offline Delay property to specify the
period of time (in seconds) that the SmartServer waits before marking a
data point and its parent device offline (red) in the SmartServer tree after
the LON driver detects that the data point is offline.
For example, if you poll a data point every 5 minutes and you set Use
Offline Delay to 1 hour, it takes 12 polls for the data point and its parent
device to be marked offline—even though the LON driver detected that it
could not communicate with the data point after the first poll.
6. Optionally, you can click Advanced to set the retry timer and retry counts
that determine the frequency in which network messages are re-sent to a
device after no confirmation of delivery is received. Although you can
change these properties, it is recommended that you use the default
transmit timer (512 ms) and the default retry count (3).
7. Click Submit.
Copying Resource Files
The Segment Controller needs a copy of the resource files for each device type
(luminaire and Street Light Bridge module) in the street lighting network. You
can obtain the appropriate resource files for the Street Light Bridge modules
from the Echelon Web site; you can obtain the appropriate resource files for each
luminaire type from the manufacturer.
To copy these files to the Segment Controller:
1. Open an FTP connection to the Segment Controller. See the
i.LON
SmartServer 2.0 User’s Guide
for more information about using FTP with
the SmartServer.
2. Copy the files from the downloaded (or otherwise provided) resource file
to the /lonworks/Import and /lonworks/types folders in the SmartServer.
For the /lonworks/Import folder, Street Light Bridge module files are
copied to the /Echelon subfolder. For a luminaire, its files are copied to a
folder defined by the manufacturer.
Automatically Discovering Devices
If you want the Segment Controller to automatically discover and commission
luminaires and Street Light Bridge modules within the network, you can place
the Segment Controller in Acquisition Mode. To enable this mode, 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
