Networking - Leuze multiNet plus BCL 301
i
In the Leuze multiNet plus network, up to 31 BCL 301
i
bar code readers can be networked together. The
respective network devices transmit the read data when requested to by the MA 31 or BCL 500
i
network
master. For this purpose, each BCL 301
i
is assigned its own station address, which is set using the
address switch in the MS 301, MK 301 or MA 100.
The master then transmits the data of all network devices via its host interface to a superior PLC control
system or a computer, i.e. it "collects" the scanner data in the network and transmits it to an interface on
the host computer. This reduces interface costs (CPs) and time spent programming the software.

Two-wire RS 485
The Leuze multiNet plus is optimized for fast transmission of scanner data to a superior host computer.
The multiNet plus consists physically of a two-wire RS 485 interface through which the
