Leuze multiScan over Ethernet/PROFINET
The multiScan over Ethernet/PROFINET operating mode links individual bar code readings of multiple bar
code scanners into a single decoding result. This is used, for example, on a packet conveyor system on
which the label can be affixed on either the right or left side, thereby requiring two read stations. To prevent
the host from having to always process two readings for a single packet, i.e. a decoding result and a No
Read, a multiScan arrangement is used which transmits only one reading from the two read stations to the
host; this single reading is transmitted by the multiScan master.
For this purpose one multiScan master and one or more multiScan slaves are connected together via
Ethernet/PROFINET.

Thus, from the perspective of the host, the scanner network appears to be just a single bar code
reader!
The multiScan function for Ethernet/PROFINET is possible for a minimum of 2 and maximum of
32 devices!
