AMR
Network Node
WTT16…
WTX16…
The WT…16… network node is used to receive and handle the data transmitted
by consumption meters of the Siemeca™ AMR system. In small plants, one net-
work node suffices 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 an OZW10 M-bus central unit or a Siemeca™ gateway is required. The
WTT16… network node is battery-powered, the mains-powered WTX16… version
is available for special applications.
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. Communication
between several network nodes is via radio also so that no wiring is required. All meas-
ured 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 meter-
ing devices on the network. Owing to this operating principle, all network 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 de-
scribed in data sheet N2870.
