FTP COMMUNICATION SETTINGS
The following setup information needs to be entered into the FTP Data File Transfer section of the UCM Setup web page for FTP file transfer. If
necessary, contact your IT administrator or FTP Server provider for the required information and how to download the files to your local computer. Blue Sky
Energy does not provide FTP download software or endorse any particular FTP download software. There are a variety of programs that can facilitate FTP
download, but a popular free program is FileZilla available at http://filezilla-project.org.
• Address of remote FTP server (e.g., www.myserver.com)
• User name to allow access to the remote FTP server
• Password to allow access to the remote FTP server
• Intervals between file uploads in hours; Range 0.0 ― 24.0 hours (setting of 0.0 hours disables FTP transfers)
• Selection of automatic file name increments, or overwriting of the same file name
¾ For the UCM to transfer files via FTP the Gateway IP Address in the Ethernet communications window of the UCM Setup
page must be set to the IP Address the UCM will use to access the external DNS Server. In router based systems this is typically
the IP Address of the router used for router setup. Refer to the your router’s documentation.
FTP FILE CONTENTS
The .csv format FTP file as viewed in an Excel spreadsheet is organized into two rows and multiple columns. The first row is the data name, with the
second row being the data values collected at the point in time the FTP file was sent. If a data value in a record is unavailable that cell will contain dashes (――).
A partial FTP data file is shown in Excel below.

TABLE 2
MODBUS
As part of the UCM’s communication capabilities, the industry standard MODBUS application protocol is provided both as isolated RS-485 serial and
as MODBUS/TCP (Transmission Control Protocol). MODBUS use described here assumes the user is familiar with the MODBUS protocol and its
terminology. The UCM supports RTU mode only. Refer to www.MODBUS.org for more information.
ELECTROSTATIC HANDLING PRECAUTIONS
The UCM cover must be removed to configure DIP switch and jumper settings. With the cover removed observe industry standard electrostatic handling
precautions to minimize the likelihood of electrostatic damage . At a minimum, discharge yourself by touching a water faucet or other electrical ground prior to
handling the unit and avoid touching components on the circuit board. The risk of electrostatic damage is highest when relative humidity is below 40%.
