15 RETRIEVING DATA FROM THE DAS
Overview of how the system was designed to work.
Now that you have installed your DAS and configured it to collect data from your meters and sensors, you will
want to collect the data from your DAS. This document will provide an overview for collecting data from the
DAS. Processing the data for billing reports, summaries, and other data processing are beyond the scope of this
document.
Three basic ways to collect data from the DAS:
•
HTTP download from the DAS with a browser (pull)
• FTP download from the DAS (pull)
• Enertrax DL download from the Energy Monitoring Hub. (pull)
• HTTP Post: The DAS uploads data to a database/webserver. (push)
15.1 HTTP Direct from the DAS
The DAS has the ability to export log file data to a web browser directly from the setup web pages.
To use this feature, access the DAS setup menu with your web browser. Select the “Log File Export” page from
the Log File Data menu on the left side of the page.
For each device, a separate log file will be saved. Select the device from the dropdown list provided. Specify Comma
or Tab delimited data, and indicate if column headers are required. Click the download button to download the data.
The log file format is the same as is provided by FTP and by the BMO web site. Note: All timestamps are in UTC.
When importing log files into Microsoft Excel, be sure to specify the log data is comma separated, and use a
single quote mark as the text delimiter.
15.2 FTP Direct from the DAS
The DAS will allow inbound connections for transfer of log data files using the FTP protocol. FTP to the DAS and
log in using the system admin password. Files are located in /var/log/modbus. For further information on FTP log
file transfer, please review the technote and FAQ section of the Leviton website.
15.2 Enertrax download direct from the DAS
Leviton provides a free tool called Enertrax DL that can automate the process of downloading log data from
the DAS to your Windows PC hard drive. Enertrax DL can merge new log data into existing log files on your
computer as well as provide configuration information about the DAS. Enertrax DL can also be configured to
make LAN or Dilaup calls to one or more data acquisition servers. Enertrax DL can be obtained by contacting
[email protected].
