Addressing
Each metering device is assigned a unique ID number (device number) from
the factory. This ID is transmitted by the metering device to the M-Bus system
as a secondary address.
The metering device data are generally queried using this secondary address.
Transmission of the cold quantity
In the case of device types with combined heat/cold metering, a virtual second
metering device with the serial number of the heat meter +1 will be displayed
in the M-Bus system. This device is assigned the medium "Cold" in the data
record.
E.g.: ID Heat
Readout parameters heat/cold metering
The following parameters are read out of the heat meter and transmitted to the
M-Bus control unit:
• Device number (8-digit)
• Medium/software version
• Time/date
• Error status (readout 5 or 45
times per day)
Optional via application selection:
Transmission of impulse values
If water meters with impulse output are connected to the heat meter, the heat
meter transmits the impulse measurement data in addition to the heat meter-
ing data.
