EnergyMetering

Our stationary fixed network system Z.RTU consists of a data logger (RTU1) with an embedded web-server for the collection resp. recording of the con-sumption data compatible with most popular water-, heating and cooling-meters and heat cost alloca-tors equipped with meters that communicate using the M-Bus and wireless M-Bus (868 MHz protocol, C1,T1, T2 or S1 mode).

In addition to the data logger, up to 23 mains-pow-ered, multihop capable wireless M-Bus repeaters are used in order to increase the radio range inside the building using a Mesh network and to ensure that all meters are accessible.

With this system, the data of up to 500 meters (shared between wired and wireless M-Bus devices)

can be collected and recorded for 10 years for each daily reading. The RTU can handle directly up to 20 wired M-Bus slaves but by using an additional level converter the number of wired M-Bus devices can be increased to 250 slaves.

The embedded webserver allows accessing data, re-ports generating, the setup of the M-Bus networks and the management of local inputs and outputs (I/O). The system configuration, accessing data and the overview via I/O status can be managed via a graphical display without the need of a PC.Automated email-sending of consumption data is possible. The transfer intervals can be selected from predefined cycles.

Data transfer to an FTP server is also possible.
