3.1.3.6 Hardware address
Each Neuron-Chip in a WAGO LON fieldbus coupler is provided from the
factory with a unique and unambiguous physical address, the Neuron-ID. This
address is to be found on the rear of the coupler and on an adhesive tear-off
label on the side of the coupler.
By a press on the Service-Pin at the beginning of network configuration a spe-
cial network management telegram will be send out.
With this telegram the node informs the network management tool about his
Neuron-ID, a unique 48-bit number.
During the starting up, the Network Management Tool Software uses the Neu-
ron-ID for the unequivocal addressing of the node.
For network communication the NMT software assignes automatically in the
standard applications WAGO

each node a logical address. Thereby the encoder switches are without func-
tion.
Assigning a logical address via the encoder switch on the buscoupler is only
relevant when an independent application is written in Neuron-C, the address
can be freely assigned within the program, or in an application involving a
data exchange coupler (peer-to-peer).

More information
Please find information about the LON data exchange coupler (peer-to-peer)
in the catalogue information and the expanded data sheet under:
http://www.wago.com/wagoweb/documentation/navigate/nm0dcl_d.htm
The address is adjustable in the range of 0x00 and 0xFF and is used to create
the node address.
The value of the switch at the bottom is the most significant value of the ad-
dress (upper Nibble).
The value of the switch at the top is the least significant value of the address
(lower Nibble).
Example:
For the logical address 0x63 the switch at the top is set to 3 and the switch at
the bottom is set to 6.
During the initialization the chosen address is read. If the address is changed
during the running mode, the change has no effect until power is cycled.
