Terminating resistor
R 120 Ohm
Multi-meter sys-
tem
If several Fronius Smart Meters are installed in the system, a separate address must be
set for each meter. The primary meter is always assigned address 1. All the other meters
are numbered consecutively with the address range from 2 to 14. Different types of
Fronius Smart Meters can be used in combination.
Location of the primary meter in the consumption branch
Location of the primary meter at the feed-in point
The following must be observed in a multi-meter system:
-
Each Modbus address must only be assigned once.
-
Terminating resistors must be positioned individually for each channel.
-
The primary meter and any other Modbus device must be on different channels.
-
The remaining Modbus nodes must be distributed equally.
