Network Node
The WT...16... network node is used to receive and handle the data transmitted by
consumption meters of the Q AMR system. In small plants, one network 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 gateway is required. The WTT16... network node is battery-powered, the mains-
powered WTX16... version is available for special applications.
The WT...16... network node is a component of the Q 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 meters installed in the building. Communication between several net-
work 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 QUNDIS gate-
way for remote data transmission can be used with any of the nodes.

- Page 8 Starting from version 2.2 each network node supports optical IrDa interface. This interface is always active and could be used for service with commissioning tools or for data exchange with others IrDA-able QUNDIS products. IrDA-master mode has to be started manually if network node it self should work as IrDA-master (e.g for data exchange with metering device).
