USB Stick as a Data Logger and for Updating Invert-
er Software
USB stick as a
data logger A USB stick connected to the USB A socket can act as a data logger for an inverter.
Logging data saved to the USB stick can at any time
-
be imported into the Fronius Solar.access software via the included FLD file,
- be viewed directly in third-party applications (e.g., Microsoft® Excel) via the included
CSV file.
Older Excel versions (up to Excel 2007) have a row limit of 65536.
Data on the USB
stick If the USB stick 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 customer. The file
must not be deleted separately; only ever delete all of the files (sys, fld, csv) in one go.
- 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® Excel)
Data structure on the USB stick
(1) USB root directory
(2) Fronius inverter (Fronius Galvo or
Fronius Symo)
(3) Inverter number - can be set in the
Setup menu under DATCOM
If there are several inverters with the same
inverter number, the three files will be sa-
ved in the same folder. A digit is added to
the file name as a suffix (e.g.: DALO_02.fld)
