Technical description

Network nodes RNN5 receive and process data from consumption metering devices (maximum 500) within the AMR system. Several net-
work nodes (maximum twelve) form a network. There are different types of network node for the different application cases. All types can be
combined with one another in a network.
Components RNN5
The network node RNN5 is made up of the following components:
Power supply:
Battery for RNN5-STD
Mains adapter for RNN5-230V
Memory
500 measuring devices
Backup battery
Transmitter and receiver are used for recording the data from con-
sumption metering devices and forwarding these to other network
nodes in the same network. The data memory contains the meas-
uring data from the consumption metering devices. It is protected
against temporary power failure, for instance during replacement of
the main battery, by the backup battery. Local network readout can
take place via the M-Bus interface (an M-Bus load).
The network nodes RNN5-230V have an additional RS232 inter-
(*)
face for readout purposes.
Keys
The network node has 3 keys with the following functions:
DISPLAY Key (10) for switching over the display and acknowledg-
ing faults.
MODE Key (9) for switching installation mode on or off. If an
extended mode is active, this key is pressed to return to
the standard mode.
RESET Recessed key (7) for triggering a network reset (interrup-
tion of all connections between the network nodes).
