This section describes the radio communication management
implemented. For the WM-Bus interface there is a test mode that
can be activated via NFC (only before the passage of +- 5 liters),
that allows to verify the correct functioning of the device. With an
NFC command the WM-Bus interface will be enabled for 1 minutes
sending standard transmission data every 5 seconds. After this
cycle the thermal energy meter will return to the initial mode waiting
for the passage of +- 5 liters.
For wired M-Bus transmission or pulse inputs activation see the separated wired M-Bus or
IR-MB-PULSE
documentation.
Note
: module
compatible from Hydrocal-M4 serial number 05053000.
The transmission of the packets will take place according to the default schedule or chosen by the customer via NFC.
An ordered schedule is provided based on the selected WM-Bus packets (default: standard packet every 200 second of transmission).
If the transmission is < 200 seconds, the transmission will be asynchronous otherwise synchronous.
Wireless MBUS - OMSv4 certified (output configuration Wireless MBUS only). As soon as radio operation mode is activated, the thermal
energy meter sends a radio telegram according to Wireless MBUS, T1 mode (unidirectional and synchronous transmission).
Preconfigured Radio parameters (AMR and synchronous mode, OMSv4 certified):
›
Transmission frequency: every 200 seconds (current values)
›
Transmission interval: every day, from 0 to 24 h
›
Encryption: disabled (default)
›
No historical data
›
Transmitted data: standard data (heating energy, heating volume), errors, battery value as a percentage
It is possible to change the configuration into Walk-By or Advanced mode with BMetering NFC Config app:
›
Transmission frequency: configurable (minimum 60 seconds)
›
Transmission interval: from Monday to Friday (optional Weekend), maximum 12 hours per day
›
Possibility to select a 24-hours’ time span with the following mandatory conditions:
›
Transmission frequency: > 300 seconds (synchronous)
›
Historical data disabled
›
Encryption: enabled/disabled
›
Historical data (12 months)
›
Transmitted data:
›
Standard data (max. 13 bytes): heating energy, heating volume
›
Combined (max 28 bytes): standard data with the addition of optional cooling energy and cooling volume
›
Instantaneous (max. 31 bytes): standard data with the addition of optional instantaneous data
›
Pulses (max. 31 bytes): standard data with the addition of optional data regarding pulse input 1 and 2 (if used)
›
Battery value as a percentage
›

›
12 months of heating energy and 12 months of heating volume*
›
12 months of cooling energy and 12 months of cooling volume*
›

During the JOIN to the network procedure, if the LoRaWAN
transmission has been activated, the radio symbol will flash
quickly on the display (at a period of 1 second) until the device
reaches the JOINED state and then remains always active. In the
case of a failed JOIN the radio symbol turns off.
In the case of wM-BUS mode only after swi/- 5 liters the
icon will remain permanently active.
In the case of wired M-Bus mode only after swi/- 5 liters
the
icon will remain permanently active.
The radio icon
will flash quickly during a transmission (LoRaWAN
or wM-Bus) in cases where the device has reached the JOINED
state or when only wM-Bus mode is active.
During the wM-Bus and/or LoRaWAN test procedures, after starting
the procedure via NFC app, the following cases will be handled:
›
WMBUS_TEST_MSG
: the icon
will remain active for 1
minutes and will flash quickly on the display (at a period of 1
second) with each wM-Bus package sent. After that time the icon
will turn off.
›
LORA_TEST_JOIN
: the radio icon
will start flashing quickly on
the display (at a period of 1 second).
If the join operation was successful, the icon will remain stable
for 1 minute and then turn off otherwise it will continue to flash
until all join attempts are concluded. In the case of a forced join
procedure, after the passage of +- 5 liters, the icon will flash
throughout the 6 minutes cycle to various SFx and then remain on
or off depending on the outcome of the join request.
