SolarNet - Basics
SolarNet is the basis for unlimited, individual application of DATCOM
components. SolarNet is a data network used to exchange data between
several FRONIUS IG or Fronius IG Plus devices and DATCOM compon-
ents.
The SolarNet data network operates as a ring-shaped bus system. A
single data link between the individual components enables communicati-
on between one or more Fronius IG or Fronius IG Plus devices and DAT-
COM components. This minimizes the cabling effort for the individual
DATCOM components.
DATCOM components are available as plug-in cards (similar to the PC).
The Fronius IG and the Fronius IG Plus can be equipped with up to three
plug-in cards within the housing.
For increased flexibility, DATCOM components are also available in versi-
ons with an external housing (box).
