3.2.3.7 Hardware address

Each Neuron-Chip in a WAGO LON fieldbus controller 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 controller and on an adhesive tear-off
label on the side of the controller.
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 application WAGO TOPLON
Thereby the encoder switches are without function.
With the address setting via the encoder switches in WAGO TOPLON
the first byte of the Location ID (information on the fieldbus node location) is
generated.
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:
If the logical address 0x63 is set with the switch at the top to 3 and the switch
at the bottom to 6, the first byte of Location ID is generated to 01100011.
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.
