Network operation BCL 301
i
in the Leuze multiNet plus
In Leuze multiNet plus network operation, the incoming bus is connected to BUS IN and the outgoing bus
to BUS OUT. If the network address of the BCL 301
i
is not 0, the device starts up in multiNet slave mode
and attempts to make contact with a multiNet master.
If BUS OUT is not used for the continuing connection to the next participant, BUS OUT must be terminated
with a terminating resistor. For this reason, a terminator plug is available for the MS 301 (see chapter 13.5
"Accessory – Terminating resistor"); in the MA 100 and the MK 301, termination is activated by a switch.
The device address is set in multiNet via the slide or rotary switch provided for this in the MA 100, MK 301
or MS 301.
NOTE
The left side of the housing of the MA 100 features a metal bracket for connecting functional
earth FE to the installation surface (e.g. metallic equipment).
The MA 100 contains a shielding terminal for the shielding connection of the KB 301-3000.
NOTE
The bus is looped through the MA 100, i.e. the bus is not interrupted when the BCL 301
i
is
removed from the KB 301-3000. The bus is terminated via slide switch T in the MA 100. If the
termination is activated (slide switch T in the ON position), the downstream bus is disconnected.
NOTE
Due to the lack of the address switch, the KB 301-3000 cable hood connection variant is not
possible on the BCL 301
i
without the MA 100 terminal box, in contrast to the BCL 300
i
