Network Node of INDIV-5 AMR
Application
The INDIV-5 AMR network node is used to receive
and handle the data transmitted by INDIV-5 Heat
Cost Allocator of the AMR system. In small plants,
one network node suces as a data collector. In
larger plants, or when consumption data shall be
read out from a remote location, an M-bus
interface for connection to a gateway is required.
The NNB-Std network node is battery powered,
the mains powered version is available for special
applications.
meters installed in the building. Communication
between several network nodes is via radio also
so that no wiring is required. All measured values
acquired by the consumption meters are
continuously exchanged within the network,
which means that every network node stores the
current consumption values, the values read out
at the end of the month, and the set day values of
all metering devices on the network. Owing to
this operating principle, all network data can be
read out at any of the nodes, or a INDIV-5 AMR
gateway for remote data transmission can be
used with any of the nodes.
Functions
• Reception and storage of the data transmitted
by the consumption meters
• Automatic creation of a network with up to 12
network nodes (with a maximum of 500
consumption meters)
• Passing on all relevant consumption values to
all network nodes on the network
• Communication via the INDIV-5 AMR gateway
Ordering
Combinations
The network node is a component of the AMR
system. It has been designed for use in buildings
to create a radio network for receiving and
storing the data transmitted by the consumption
Device Description Code no.
NNB-Std Standard battery-powered network node 088H2332
Note! Mains powered version is available on request.
All network nodes with integrated gateway can
be used along with any other network node. The
maximum number of 12 network nodes in one
system must not be exceeded.
The network nodes with gateway and integrated
M-Bus master (NNV-IP) are able to read M-Bus
meters according to EN13757-2/3.

Technical design
The network node consists of the following
subassemblies:
Power supply:
• mains supply network node
• battery NNB-Std
M-Bus
(Slave)
Memory for
500 meters
AMR network
Transciever for
Back-up battery
RS232
(optional)
Receiver and transmitter are used for receiving
consumption data and forwarding them to other
network nodes of the network. The memory
stores the consumption data. It is protected
against temporary power drops (e.g. mains
power failure or replacement of the main battery)
by a backup battery. The network can be read
locally via the M-Bus interface.
NNB-Std node is battery operated, while the
mains powered version requires a mains power
supply 100 - 230 VAC.
Electronics section
The housing with the electronics is identical for
all types of network nodes. It contains the

Basic design
The network node consists of 2 major sections:
the base and the housing with the electronics. It
is thus possible to mount the base prior to
commissioning, enabling the electrical installer
to connect the mains powered network node to
the mains network.
At the time of commissioning, the electronics
section is snapped on and the electrical connections are made.
Wall-mounted section
The wall-mounted section of the network node
NNB-Std contains only the main battery. The wallmounted section of the mains powered network
node contains the power pack and possibly an
optional RS232 interface.

Display,
levels
The display of the network node facilitates commissioning work and troubleshooting.
In addition to the standard display that shows the operating mode of the NNB-Std, there are 5
dierent display levels from “A“ to “E“ that can be selected by the user.
Level Display Explanation
- Current operating mode
A
Network node number (primary address) and alternate network
number
B Number of network node on the network
C Number of consumption meters on the network
D Remaining capacity of the NNB-Std main battery in %
E Error code (3 groups)
Display,
operating modes
There are dierent operating modes some of which can be selected by pressing the button on the
network node; some are selected automatically, or from a connected PC via the ACT26 commissioning
software. The selected operating mode appears on the display.
