Other data telegrams are available on request (e.g. special telegrams for mobile
data acquisition).
The RF module is powered via the meter. If the meter is to be powered by a bat-
tery, a D-cell must be used.
The WZU-GPRS module is a GSM/GPRS module with M-bus master. The module
reads the values of the meter that supports the M-bus protocol and stores the data.
It is supplied complete with an external antenna.
Reading and storing measured values of the heat/cooling energy meter
Reading and storing measured values of any metering device conforming to the
M-bus standard protocol
Collection of measured values per e-mail, FTP, http, SMS transparent GSM or
TCP
Configurable report templates for manufacturer-specific reports on values, about
the system, etc.
Configurable per SMS, http, or Telenet
Updating applications, firmware and resources via GPRS remote control
The module must be plugged into socket 2.
The module has a built-in M-bus master, capable of reading up to another 8 M-bus
meters. If the bus is overloaded, communication problems with the connected
slaves occur.
All connected M-bus devices (slaves) must have an unambiguous M-bus second-
ary address.
The module (WZU-GPRS) is supplied complete with the required power supply
module (rated voltage AC 100…240 V).
