Within the FRONIUS IG, the plug-in cards communicate via its internal network. External
communication (LocalNet) is implemented using the COM cards. Each COM card has
two RS-485 interfaces as its input and output. RJ45 plug connectors are used to connect
to these cards.
The first FRONIUS IG with COM card can be up to 1,000 m away from the last FRONI-
US IG with COM card.
