USB Stick as a Data Logger and for Updating In-
verter Software
USB flash drive
as a datalogger
If a USB flash drive is connected to the USB A socket it can function as a data-
logger for an inverter.
The logging data stored on the USB flash drive can be viewed at any time in
third-party programmes (e.g Microsoft® Excel) using the CSV file logged at the
same time.
Older versions of Excel (before Excel 2007) are limited to a maximum of 65,536
rows.
Data on the USB
flash drive
If the USB flash drive is being used as a data logger, three files will be created
automatically:
-
FRONIUS.sys system file:
This file stores information from the inverter that is irrelevant to the custom-
er. The file must not be deleted separately. Only delete all of the files (sys,
fld, csv) at one time.
-
DALO.fld log file:
A log file for reading the data in the Fronius Solar.access software.
Further details on the Fronius Solar.access software can be found in the
"DATCOM Details" operating instructions at http://www.fronius.com
-
DATA.csv log file:
A log file for reading the data in a spreadsheet program (e.g.: Microsoft® Ex-
cel)
Data structure on the USB flash drive
(1) USB root directory
(2) Fronius inverters (Fronius
Galvo, Fronius Symo, Fronius
Primo or Fronius Eco)
(3) Inverter number - can be set in
the Setup menu under DAT-
COM
If there are several inverters with the
same inverter number, the three files
will be saved in the same folder. A digit
is added to the file name as a suffix
(e.g.: DALO_02.fld)
