4. M-Bus Slave to MULTICAL
The M-Bus Slave is built-up as a module, which fits
directly into the integrator bracket of MULTICAL
The M-Bus Slave has been specially constructed
®
for MULTICAL
.
The M-Bus Slave is supplied via the M-Bus Master,
and there is a galvanic decoupling to MULTICAL
which cannot be supplied over the M-Bus Master.
The M-Bus Slave is equipped with either two extra
in/- or outputs, to facilitate remote data acquisi-
tion from other meters, e.g. water meter or to read
out the energy and volumes pulses from the meter
itself.
The M-Bus Slave is an intelligent unit with its own
processor and RAM.
The M-Bus Slave automatically collects data from
the heat meter every 12 hours. Furthermore, data
is collected from the heat meter at reset/start and
when data has been sent from the M-Bus Slave to
the M-Bus Master.

There is a difference between the M-Bus Slaves for MULTICAL
®
MULTICAL
transmits a larger amount of data. Please refer to paragraph 10: Data acquisition of M-Bus.
The M-Bus Slave is reset by decoupling the M-Bus
®
.
system for some time (minimum 1 min.).
The M-Bus Slave can also be initiated from the
M-Bus Master by sending the format SND_NKE. Ini-
tialization means that the internal counters are re-
set and data are collected from MULTICAL
®
,
For the creation of M-Bus data packs the M-Bus
Slave uses the codings of MULTICAL
If the coding cannot be found in the M-Bus Slave
an error message appears which means that the
decimal point will not be correctly placed in the
M-Bus data pack.
Each M-Bus Slave has a maximum current con-
sumption of 1 Unit Load (1.5 mA).
Rin = 410 W, Cin = 1 nF.
