Setting the Network and Device Addresses
You must assign a new IP network address to the NIE29, so it can communicate on the IP Ethernet network. The
NIE29 MAC address is fixed and is printed on a label on the housing.
The NIE29 is always the SA Bus supervisor and, therefore, always has a fixed device address of 0 on the SA Bus.
The supervisory controller on NIE29 models that support an (MS/TP) FC Bus is always an FC Bus supervisor and
has a fixed device address of 0 on the FC Bus. The field controllers in all the NIE29 models have fixed device
addresses of 4 on the NIE FC Bus.
Refer to the
MS/TP Communications Bus Technical Bulletin (LIT-12011034)
for more information on device addresses
on (MS/TP) FC Buses and SA Buses.
NIE29 models that support an N2 Bus are always bus supervisors on the N2 Bus, and they do not require a user
assigned device address to communicate on the N2 Bus.
NIE29 models that support a L
ON
W
ORKS
network trunk are assigned a unique, factory-assigned Neuron
®
ID. A
network management tool, such as LN Builder, uses this Neuron ID to set the domain, subnet, and node address
of the NIE29 for communication with L

ORKS
devices.
The NIE29 Modbus integration always serves as a Modbus master and does not require a user-assigned device
address.
Binary Output Source Power Selection Jumpers
The BO source power selection jumpers determine whether a BO provides internal power (sourced from the NIE)
to the output load (INT position) or requires an external power source (EXT position) for the output load.
shows an example of the NIE controller BOs and the associated power selection jumpers next to the BO terminal
blocks.
Position the jumpers next to the BO terminals to provide either internal 24 VAC power to the BO load or act as a
switch for an externally powered BO. Each NIE29 BO wired in an application must have the jumpers positioned
properly for the application. See
.
Important:
Do not connect an external power source to a BO when the BO power source jumper is in the internal
power (INT) position. Connecting external power to a BO that sources internal power can damage the
controller and void any warranties.
