NOTE! Be sure to follow the general ESD regulations when fitting plug-in cards.
When installing add-on system components in the form of plug-in cards, proceed as
follows:
WARNING! Danger due to mains voltage and DC voltage from solar modules.
The connection area and options area should only ever be opened by an
authorised electrical engineer, and only when the power is disconnected.
The FRONIUS IG supports many different add-on system components such as:
-
Datalogger (for using a PC to record and manage data from your photovoltaic
system), including datalogger and modem interfaces
- Various large-format displays (FRONIUS IG Public Display)
- Actuators / relays / alarms (FRONIUS IG signal card)
- Sensors (temperature / insolation / consumption meter)
- String control
NOTE! To analyse data, you will need FRONIUS IG.access Version 5.0 or later
These add-on system components are supplied in the form of plug-in cards (similar to
those for a PC). To increase flexibility, certain add-on system components can also be
supplied in an external version with a separate housing. The FRONIUS IG can accom-
modate four plug-in cards internally.
FRONIUS developed LocalNet to make these add-on system components flexible and
capable of being used in a wide variety of different applications. LocalNet is a data
network which enables one or more FRONIUS IGs to be linked up with the add-on
system components.
The nucleus of the LocalNet is formed by the datalogger. It coordinates the data traffic
and makes sure that even large volumes of data are distributed quickly and reliably.
To incorporate the FRONIUS IG into the LocalNet, the following add-on system compo-
nent needs to be installed in a slot in the FRONIUS IG:
The COM card, which is installed in the FRONIUS IG at the time of manufacture; this
allows the FRONIUS IG to establish a data interface with the LocalNet and the add-on
system components to which it is connected.
NOTE! A COM card is still required even if the datalogger is to be used to log
data from only one photovoltaic inverter. In this case, the COM card acts also as
a link between the internal network of the FRONIUS IG and the LocalNet
interface of the datalogger.
