Note: Where there are several devices on a bus system, to provide
a clearer differentiation between them it is advisable to enter
a symbolic name in each device by way of parameter

LustBus interconnection OF INVERTER MODULES
By way of the serial service interface (RS232) a bus system can be set up
based on the proprietary L
USTBUS PROTOCOL. The basic layout is shown
in the graphic below. For protocol information relating to the interconnec-
tion of inverter modules refer to the detailed documentation: “Data trans-
fer protocol, L
USTBUS”.

USTBUS via bus interface TK100
LUSTBUS interconnection
By way of the bus interface T-coupler TK100 an electrically isolated bus
system is set up based on the serial interface to RS485 standard. Bus
users can be connected up via interfaces of type RS485 or RS232.
