2.2.3 Functions
The M-bus central unit
identifies connected M-bus and Siemeca™ AMR devices with the help of its auto-
matic search run: For detailed information, refer to section 8.3 “Search run of cen-
tral units OZW10 and OZW111".
acquires and stores the consumption data of the M-bus and Siemeca™ AMR de-
vices at regular intervals
displays the stored consumption data
copies the stored consumption data to a billing file of the memory card at the press
of a button
makes possible to access
stored consumption data
the memory card
directly the M-bus devices by means of a PC connected either directly or via mo-
dem (V3.0 or higher)
monitors periodically the M-bus and Siemeca™ AMR devices and 4 potential-free
digital inputs
indicates alarms
on the display
via alarm relay
to a PC, either directly or via modem (V3.0 or higher)
The M-bus central unit can be parameterized in 2 different ways:
Via the buttons of the M-bus central unit
With a PC, connected directly or via modem, with the help of the ACS service soft-
ware (only directly) or the ACS operating software (directly or via modem)
On request, the M-bus central unit automatically searches for the M-bus and Sie-
meca™ AMR devices used by the system. Supported are primary and secondary ad-
dressing (type of addressing on the M-bus) and the Baud rates 300, 2,400 and 9,600
Baud (Baud rates on the M-bus). The type of addressing and the Baud rates can be
selected.
