Siemeca™ AMR
Network nodes
with gateway WTX16.GSM
WTX16.IP
WTX16.MOD
The WT…16… network nodes are used to receive and handle the data transmitted
by consumption meters of the Siemeca™ AMR system. They are equipped with a
gateway that can provide data of up to 2,000 meters for remote readout.
WTX16.IP can be read via Ethernet while WTX16.GSM and WTX16.MOD contain a
GSM modem. They are read via the telephone network.
Use
The WT…16… network node is a component of the Siemeca™ system.
It has been designed for use in buildings to create a radio network for receiving and
storing the data transmitted by the consumption meters installed in the building. Com-
munication between several network nodes is via radio also so that no wiring is re-
quired. 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 val-
ues of all metering devices on the network. Owing to this operating principle, all net-
work data can be read out at any of the nodes, or a Siemeca™ gateway for remote
data transmission can be used with any of the nodes.
The field of use of the Siemeca™ AMR system is described in Data Sheet N2870.

The transmitter and the receiver are
used to collect data from the consump-
tion meters and to forward theses data to
other nodes in the network the data
memory stores the consumption data. It
is protected against temporary mains
power failures by the backup battery.
The network nodes WTX16.GSM and
WTX16.IP are equipped with a gateway
to store data of up to 2000 meters and to
provide a possibility for remote readout
via GSM or Ethernet. The gateway has
an additional M-Bus master that can
drive up to 5 external M-Bus unit loads
(e.g. up to 5 M-Bus meters). Usually,
however, the M-Bus master is used to
connect nodes of different networks to
be able to read more meters using only
one gateway.
The gateway can be programmed using
an additional RS-232 interface.

The network node WTX16.MOD is equipped
with a gateway for remote readout via GSM
or GPRS.
It has no M-Bus master, though. Therefore it
can read data from one network only (max.
500 meters).
The WT…16… consists of 2 major sections: The base and the housing with the elec-
tronics. It is thus possible to mount the base prior to commissioning, enabling the elec-
trical installer to connect the WTX16 to the mains network. At the time of commission-
ing, the electronics section is snapped on and the electrical connections are made.
The electronics section is identical for all types of network nodes. It contains control
elements of the network:

3 Extra insulation (shrink sleeve)
Connect the AC 230 V power supply line to the power pack of the
WTX16… in the following order: Remove the upper housing section of
the WTX16… from the base. For that purpose, remove the 2 cable
connections (power supply (4) and M-Bus (6)) between gateway and
base. Then, use a suitable tool (screwdriver or similar) to slightly open
one of the two lateral fixing levers so that upper housing section and
base can be separated. Then, the top section of the WT…16 is to be
fitted using 2 dowels and screws (spacing of dowels is 184 mm with
the WTX16…).
Connection of the AC 230 V power line to the power pack of the WTX16… is to be
made as follows:
A 2-core mains cable (L and N) has to be preinstalled at the mounting site already. The
power pack must be connected by qualified staff. The cores must be sheathed with the
en-closed insulating sleeves to ensure compliance with safety class II. Then, the live (L)
and neutral (N) conductors must be connected to terminal “IN” of the power pack.

Mains voltage must be in the range from AC 100 to 240 V (50 / 60 Hz). There is no
protective earth (PE) connection. Then, cable strain relief must be provided by fitting
cable ties.
Once the top section of the WTX16 is fitted, the housing with the electronics can be
snapped on. Then, the power supply connector can be plugged into the electronics
section and the WTT16 switched to installation mode by pressing the MODE button
(red) for a few seconds. Then, additional network nodes or consumption meters of the
Siemeca™ AMR system can automatically configure themselves to form a network.
After the complete installation of the network the gateway must do a search run to find
all meters of the network(s). One can start a search run either by restarting the
WTX16… by disconnecting it shortly from the mains power (switch S) or by triggering it
with a command sent by the commissioning software ACT21 from a PC attached to the
network node.
Screw tight the GSM antenna prior to commissioning
Network nodes WTX16.GSM require a SIM card. For that purpose,
remove the upper section of the WTX16.GSM from the base. Remove
the 2 cable connections (power supply and M-Bus) between gateway
and base. Then, use a suitable tool (screwdriver or similar) to open
one of the two lateral fixing levers so that upper housing section and
base can be separated.
Insert the SIM card in the slot at the bottom of the gateway.
