nents. Fronius Solar Net is a data network which enables several Fronius inverters to ex-
change data with DATCOM components.
The Fronius Solar Net data network operates as a ring-shaped bus system. A single data
link between the individual components enables communication between one or more Fro-
nius inverters and the DATCOM components. This minimizes the cabling effort for the in-
dividual DATCOM components.
DATCOM / Plug-in
DATCOM components are available as plug-in cards (similar to the PC). Depending on the
card principle
country setup, Fronius inverters can be equipped with up to three plug-in cards within the
housing.
Plug-in cards communicate within the inverter via its internal network. External communi-
cation to Fronius Solar Net takes place via Fronius Com Cards.
DATCOM compo-
For increased flexibility, DATCOM components are also available in versions with an ex-
nents with exter-
ternal housing (box).
nal housing
DATCOM components with external housings are designed in accordance with degree of
protection IP 20. For this reason, they are suitable for interior applications only or must be
placed in an appropriately rated weather-proof housing.
If required, the base of an external housing can be clipped onto a commercially-available
DIN rail.
DATCOM components with external housings are equipped with an input „IN" and output
„OUT" for data communication within the network.
