Core of Fronius
Solar Net: the Da-
talogger The core of Fronius Solar Net is the Datalogger. It coordinates data transmissions and en-
sures that even large volumes of data are distributed and stored quickly and securely. In
addition, the Datalogger also records data for the entire system over long periods of time.
The following devices have a Datalogging function:
-
Fronius Datalogger pro
The Datalogger pro can record data from up to 100 inverters and 10 sensor cards/
boxes.
- Fronius Datalogger easy
The Datalogger easy can only record data from the inverter and sensor card / box us-
ing Address 1.
- Fronius Datalogger Web
The Datalogger Web can record data transmitted via the Internet from up to 100 in-
verters and 10 sensor cards/boxes.
- Fronius Personal Display DL Box
The Fronius Personal Display DL Box can record data from up to 100 inverters and
one sensor card/box.
The Fronius Datalogger easy / pro has
-
two data interfaces for direct data transfer to the PC (RS232 and USB)
- one data interface for remote PC data queries via modem and telephone line (RS232)
The Fronius Datalogger Web has a 10/100 MBit Ethernet interface.
Fronius Com
Cards for con-
necting inverters
to Fronius Solar
Net Fronius Com Cards provide the data link from a Fronius inverter to Fronius Solar Net and
to the DATCOM components connected to it. In addition, Fronius Com Cards also offer gal-
vanic isolation between the photovoltaic ystem and the inverters providing additional safe-
ty. Fronius Com Cards must be installed in each inverter connected to Fronius Solar Net.
Each Fronius Com Card is equipped with two RS 422 interfaces - an input and an output.
The input is labeled „IN“ and the output is labeled „OUT.“
IMPORTANT! In the rest of this manual, the Datalogger pro, Datalogger easy and Data-
logger Web are only referred to specifically if the information relates solely to that version.
The term "Datalogger" is used on its own for information that relates to Datalogger pro, Da-
talogger easy and Datalogger Web.
NOTE! Every Fronius inverter to be monitored using a datalogger requires a
COM Card, even if the system only contains one Fronius inverter. In this case, the
Fronius Com Card serves as a link between the internal network of the inverter
and the Fronius Solar Net interface of the datalogger.
