Addressing in the network

Addressing via ASCII address
Addressing the individual barcode readers or devices is necessary for the functioning of the
network so that the data read can be matched to a station. Leuze uses 2-byte ASCII
addressing in multiNet plus. This addressing is included in each data telegram. This address
must be selected at the stations via software or hardware (rotary switch).
The following rules apply:
Master (MA 30):
Slaves:
No address may occur twice in the network. The numbering must be without gaps, i.e. all
addresses up to the last slave address (=last subscriber in the network) must be occupied.
Notice!
Be careful to select the network addresses correctly during commissioning.
The logical order of the assigned addresses does not have to correspond to the physical or-
der of the read stations in multiNet plus.
