14 LOG FILE DATA
When the EMB HubLite storage area on the flash starts to run out of space, the following action is taken:
•
When the 8 MB log file storage area is 75% full, the EMB HubLite will immediately compress the log files
and attempt to upload the data to the BMO website or user specified site. This action will not wait until
the next scheduled upload time.
•
When the storage area is 95% full, the EMB HubLite will immediately attempt to upload the data, and if
unsuccessful, will purge the oldest (rotated) log data file.
Log files are deleted automatically if the EMB HubLite has successfully uploaded the log file to a database
server using the HTTP/Post protocol. If you do not configure the EMB HubLite to automatically push the
log files to your server, you must manually delete them. To delete log files, refer to the FTP method of
downloading log files. One step detailed in the FTP section is how to delete a log file from the EMB HubLite.
14.4 Uploading data to the BMO website
After the EMB HubLite has been configured and has logged some data, you will want to collect the data
for analysis. There are several ways of collecting the data from the EMB HubLite including the Building
Manager Online service. Other methods are noted in the data collection FAQ. This section details
configuring the EMB HubLite for use with the BMO service.
14.4.1
First, use your browser to connect to the EMB HubLite. Select the Modbus/Setup section from
the menu on the left. In the field titled “Modbus Loop Name” enter a name for this EMB HubLite
to uniquely identify it on the BMO website. Because the BMO site can show multiple
EMB HubLite devices, it is important to have a descriptive name in this field.
14.4.2
Select the “Log File Data”, “Setup/Upload” menu option. The following features are available:
•
EMB HubLite Serial Number:
This is the serial number that uniquely identifies this
EMB HubLite. This number can not be changed. When uploading data to the BMO website,
this serial number is used to identify the EMB HubLite to the BMO server.
•
Scheduled upload time:
This option allows you to control when the EMB HubLite will
initiate the upload process. You can select any hour of the day, and the EMB HubLite will
select some time at random within that hour to start the upload. The random feature allows
multiple EMB HubLite devices to share a single dial up account or phone line by not starting
the dial out at the same time for all devices. If the EMB HubLite is on a LAN connection
(DSL, Cable Modem, T1, etc) an upload time of “hourly” may be selected.
•
Upload data on alarm status change
will cause the EMB HubLite to initiate the upload
process if any point on any modbus device enters or leaves an alarm state. This allows the
EMB HubLite to send data when an alarm is detected, and will upload that information to
the BMO website in a timely manner. The BMO website will then send email notifications if
necessary. If this option is disabled, the BMO website may not be able to send notifications
until the end of the day when the EMB HubLite calls in at its specified upload time.
•
Upload data on low disk alarm
: This feature will cause the EMB HubLite to attempt a data
upload immediately if the log file storage area is more than 75% full.
