Setting Up the Segment Controller

4. If a network message fails, a data point and its device are marked offline.

You can select the Use Minimal Offline Time checkbox so that all the

data points on the offline device with pending network messages

(read/write requests, polls, or heartbeats) are marked offline and network

messages are not sent to them. Thus, network performance is not

impacted by an offline device.

You can also set the minimum period of time (in seconds) that the

Segment Controller waits before transmitting network messages to

offline data points. During this period, an offline device transmits an

OFFLINE status in response to data point requests. After the Minimal

Offline Time elapses, the Segment Controller 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 Segment Controller waits before

marking a data point and its parent device offline (red) in the Segment

Controller 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 CRD 3000 Street Light Bridge module) in the street lighting

network. You can obtain the resource files for the CRD 3000 Street Light Bridge

module from

. 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 User’s Guide for more information about using FTP with the

Segment Controller.

2. For the Street Light Bridge files, unzip the downloaded file to the

Segment Controller’s root folder. The files should unzip to the correct

subfolders.

3. For luminaire files, copy the files from the downloaded (or otherwise

provided) resource files to the folder defined by the manufacturer,
