1)
The scope of data of these M-bus devices can be parameterized. If the application
used is different from the standard application, the load must be determined accord-
ing to section 7.5 "Storage space requirements of M-bus devices".
2)
The scope of data of the Siemeca™ AMR devices is determined by the WTX16 or
WTT16 radio node on the M-bus, where it can be parameterized. If the application
used is different from the standard application, the load must be determined accord-
ing to section 7.6 “Amount of storage space required by Siemeca™ AMR devices”.
For meters of other manufacture, the amount of storage space required must be deter-
mined depending on the project. The storage space required depends on the type of
device and its version. To calculate the amount of storage space, the M-bus telegram
specification of the relevant device is required.
General rule: The amount of storage space required corresponds to the telegram
length in bytes minus 4.
5.3.2 M-bus central unit OZW111
Internally, the OZW111 only stores the device list and the alarm data. The amount of
storage space required is the same for all connected devices. The device data are ac-
cessed directly via the ACS7… . Direct access to the devices is made possible via a
transparent data channel.
When using the OZW111, the maximum number of M-bus devices is limited to 5. Fol-
lowing must be noted however:
