M-Bus water meter flowIQ® 2101/3100
This technical description describes the wired M-Bus interface of water meters flowIQ 2101 and flowIQ 3100.
For further technical information about these water meters, please refer to their respective Technical Description.
•
M-Bus is a bus system especially suited for communication with consumption meters. The system consists of an
M-Bus Master and one or more meters with M-Bus interface.
M-Bus is standardized in the European standard EN 13757, as well as in the OMS TR02.
Communication on the M-Bus is an asynchronous serial bit transmission in half duplex mode, which means that it is
possible only to transmit one way at a time on the M-Bus.
The framing of the communication is 1 start bit, 8 data bits, 1 parity bit (even) and 1 stop bit.
The M-Bus is communicating via voltage modulation from the M-Bus Master to the M-Bus water meter and current
modulation from the M-Bus water meter to the M-Bus Master. Communication media is via an ordinary two-wire
cable. A twisted pair, non-shielded cable is recommended.
The M-Bus water meter supports primary, secondary and enhanced secondary addressing as well as 300, 2400 and
9600 baud communication speed.
The M-Bus water meter flowIQ® 2101/3100 are designed with manufacturer specified VIF extensions, so called
VIFE codes.
These VIFE codes are formatting the data, whereby decoding of the content is much easier, as when using
manufacturer specified data.
The connection of the M-Bus water meter and the M-Bus network is realized with a fixed two wire cable.

Installation
•
The M-Bus interface is integrated in the flowIQ® 2101/3100.
The bus is polarity independent.
The M-Bus water meter have a max power consumption of 1 unit load (1.5 mA) drawn from the M-Bus Master.
Rin: 440 Ohm
Cin: 0.5nF
Bus current and voltages according to EN 13757-2.
The M-Bus water meters fulfil the requirements in the M-Bus standard EN 13757:2013 as well as the
OMS TR02:2015 and can be used in a wide variety of applications using M-Bus protocol.
The M-Bus water meters are designed with focus on high flexibility to fulfill a wide pallet of existing and future
applications.
The flowIQ® 2101/3100 support high quantities of data and all relevant data for analysis can be read out.
This is valid for both actual meter data as well as for target data.
All relevant data for billing purposes can be read out from the flowIQ® 2101/3100.
The wired M-Bus datagram in flowIQ® 2101/3100 is fixed and cannot be altered
The water meter can deliver online data in intervals down to 15 seconds (however at reduced battery lifetime) for
controlling and regulating purposes with a high communication speed.
As M-Bus is polarity independent there is no + and ÷ to care about.
Configuring the primary address can be done with METERTOOL HCW using an optical readout head or via the
M-Bus network. It is recommended that the entire M-Bus system is not powered up during installation of new MBus water meters.

Data communication
5.1 Bus communication
5.2 Communication interval
5.3 Addressing forms
•
The M-Bus water meter design is based on the newest technology, offering high-speed communication as well as
very frequent reading interval.
The transmission speed is automatically detected by the M-Bus water meter. When the M-Bus water meter
receives a message from the M-Bus Master on a certain speed, it will reply with the same speed.
The M-Bus water meters flowIQ® 2101/3100 supports 300, 2400 and 9600 baud communication speed.
In order to maintain the full 16 years battery lifetime of the water meter, the read out interval shall be longer than
1 minute. Since the most frequent integration interval in the flowIQ® 2101/3100 is 32 seconds, a more frequent
reading is not recommended. A more frequent reading interval than 32 seconds will provide redundant
information.
To make the M-Bus system operate with more M-Bus water meters connected, it is necessary to distinguish
between the individual M-Bus water meter. This is done by means of following M-Bus ID numbers in each M-Bus
meter:
• Primary address: 001...250, and the special addresses 0, 253, 254 and 255
• M-Bus ID number: 8 digits 00000000… 99999999
• Manufacturer ID: Always 2D2Ch for ’KAM‘ for Kamstrup M-Bus water meter
• Version ID flowIQ® 2101 1Fh
• Version ID flowIQ® 3100 1Dh
• Device type ID: 06h = Volume warm, 16h = Volume cold
• Fabrication number: Serial number, 8 digits 0000000… 99999999
When the M-Bus Master sends a message on the M-Bus, some or all of the above ID numbers on the M-Bus water
meters are encoded in the message. Thus, only the M-Bus water meter with the addressed ID numbers will reply.
Manufacturer ID, Version ID and Fabrication number are permanently encoded into the M-Bus water meter and
cannot be changed.

5.3.1 Primary addressing
A valid primary M-Bus address has a value between 000 and 250.
The primary M-Bus address is either configured specific in the flowIQ® 2101/3100 or the last digits of the meter
number are used.
As factory default, the primary address in flowIQ® 2101/3100 equals to the last 3 digits of the meter number. If the
last 3 digits are larger than 250 (e.g. 345) the first digit is ignored and the M-Bus water meter address is only
determined by the last 2 digits (e.g. 45).
During the ordering process specific primary addresses can be specified.
Changing the primary address can be performed in following ways:
• Programming with METERTOOL HCW, via Optical Readout Head
• Remotely, via M-Bus master
In connection with primary addressing of the M-Bus, two or more M-Bus water meters on the same M-Bus system
cannot have the same primary address. However, in connection with secondary addressing or enhanced secondary
addressing it is possible to distinguish M-Bus water meters with the same primary address on the same M-Bus.
•
Standard address range for an M-Bus water meter is 001... 250.
In addition to this, there are 4 special addresses that work as follows:
Adr. 000: Ordinary primary address reserved for non-configured M-Bus water meter.
Adr. 253: Used for secondary addressing.
Only M-Bus water meters selected by (enhanced) secondary addressing will reply.
Adr. 254: All M-Bus meters will reply to this address. The address can only be used in systems where only 1 M-Bus
water meter is connected.
Adr. 255: No M-Bus meter will reply to this address, but all will receive the message. This address makes it
possible e.g. to change the baud rate, on an entire system at the same time, by sending only one
telegram.

A valid secondary M-Bus address has a value between 00000000 and 99999999 and is in the flowIQ® 2101/3100
identical to the unique serial number.
In connection with secondary addressing, the M-Bus water meters are selected via the primary address 253 with its
8 byte long complete M-Bus ID consisting of:
• M-Bus ID number. Default from Kamstrup: The last 8 digits in the meter number / customer number (4 bytes)
• Manufacturer ID = ASCII characters ‘KAM’ for Kamstrup encoded to the value 2D2Ch (2 bytes)
• Version/generation ID number for MULTICAL® 21 = 34h (1 byte)
• Device type ID (1 byte)
These 8 bytes make up the secondary address of the M-Bus water meter. It is possible to replace the individual
bytes with wildcard characters. See chapter 5.3.4 for further information.
Selection of M-Bus water meter via secondary address
(and deselecting other M-Bus water meter):
•
As long as the M-Bus water meter is selected, it will reply to primary address 253, which is dedicated to secondary
addressing. The M-Bus water meter is deselected either by
• sending a new selection via primary address 253 with a secondary address – different from the one of the
M-Bus water meter (by means of which another M-Bus meter may be selected, if necessary)
or
• sending normalization (SND_NKE) to primary address 253.

A valid secondary M-Bus address has a value between (M-Bus ID No. 00000000-99999999) / (M-Bus fabrication No.
00000000-99999999) and is, in the flowIQ® 2101/3100, identical to the unique serial number.
The M-Bus water meter secondary address can therefore be extended in order to comprise the 8 digit BCD
‘fabrication number’ (4 bytes) – identical with the serial number of the meter. This number is unique for each
flowIQ® 2101/3100 and cannot be changed after the meter has been produced.
In connection with enhanced secondary addressing, the M-Bus water meter is selected by adding ‘fabrication
number’ as an ordinary data record with DIF = 0Ch (for 4 bytes, 8 digit BCD) and VIF = 78h (for fabrication number)
in the selection telegram after the secondary address.
When a M-Bus water meter is selected via enhanced secondary address, it will reply to primary address 253, as it is
with the ordinary secondary addressing. The M-Bus water meter is deselected either by
• sending a new selection via primary address 253 with an enhanced or ordinary secondary address – different
from the one from the M-Bus water meter (by means of which another M-Bus meter may be selected, if
necessary)
or
• sending a normalization (SND_NKE) to primary address 253.

Note:
•
The M-Bus water meter supports wild card search for an easy search for connected meters. Some or all digits of
the meters secondary and/or enhanced secondary addresses can be replaced with wild cards when searching for
meters in an M-Bus network. The integrated break detection functionality eases the meter search on the M-Bus
network.
The M-Bus water meter will not compare the wildcard characters with the equivalent digits in “its own” secondary
and enhanced secondary address, and the M-Bus water meter will be selected if the other characters match.
The 8 digits in the M-Bus ID number and the 8 digits in the ‘fabrication number‘ (= serial number) can each be
replaced by the wildcard character Fh.
The binary values ‘Manufacturer ID’ (2 bytes), ‘Version / generation ID’ (1 byte), and ‘Device type ID’ (1 byte) in the
secondary address may be replaced by the wildcard byte value FFh.
The values for DIF = 0Ch (for 4 bytes, 8 digit BCD) and VIF = 78h (for fabrication number) in connection with
enhanced secondary addressing cannot be replaced by wildcard values.
By means of wildcard characters (BCD Fh) and values (binary FFh), an M-Bus Master can, relatively quickly, search
the M-Bus for connected M-Bus water meters, without knowing the M-Bus water meters primary, secondary or
enhanced secondary addresses in advance.
The M-Bus protocol comprises following telegram / message format types:
In the default application the FCB bit is not used and the M-Bus water meter accepts both FCB = 0 and FCB = 1.

Communication on the M-Bus is initiated by the M-Bus Master. After this the addressed M-Bus water meter
replies. Basically, there are 2 different communication sequences (from M-Bus Master to M-Bus water meter):
SEND -> CONFIRM
REQUEST -> RESPONSE
When using ‘SEND -> CONFIRM’ the M-Bus Master sends a command or data to the M-Bus water meter, that
replies with an acknowledgement (ACK). The acknowledgement (ACK) just means that the M-Bus water meter has
received the telegram successfully, but it has not necessarily accepted the contents.
When using ‘REQUEST -> RESPONSE’ the M-Bus Master sends a request to the M-Bus water meter, which in return
replies with a datagram according to the request.
The M-Bus water meter only supports ‘Mode 1’ data format where all multi-byte data values to and from the MBus water meter are transmitted with Least Significant Byte (LSB) first.
In the default application the FCB / FCV bit in the C-field is not used and the M-Bus water meter accepts both FCB =
0 and FCB = 1.
The M-Bus water meter does not use DFC (Data Flow Control) / ACD (Access Demand) bits, which means that both
bits will always have the value 0 in the C-Field from the M-Bus water meter.
The following describes the individual M-Bus telegrams, from M-Bus Master to M-Bus water meter and from M-Bus
water meter to M-Bus Master, that are supported.

SND_UD -> ACK
5.7 Information codes
REQ_UD1 from the M-Bus Master is a request for time-critical (alarm) data from the M-Bus water meter.
The flowIQ® 2101/3100 M-Bus water meter does not support time-critical data (alarm protocol), but it replies with
an ACK (link layer receipt) when receiving REQ_UD1, which means that the M-Bus water meter does not have any
time-critical (alarm) data to transmit.
In this way, the M-Bus water meter will function in M-Bus systems with other M-Bus interface supporting timecritical data (alarm protocol).
REQ_SKE from the M-Bus Master is a request for communication status and for information on whether the M-Bus
water meter has any time-critical (alarm) data to send. When receiving an REQ_SKE the M-Bus water meter replies
with an RSP_SKE, but as the M-Bus water meter does not support time-critical data (alarm protocol), and cannot
have overflow in its input buffer, the status bits ACD (Access Demand) and DFC (Data Flow Control) will always be =
0 in the M-Bus water meter reply, which means that the M-Bus water meter does not have any time-critical (alarm)
data to send and has no buffer overflow.
•
Therefore, the M-Bus water meter will function in M-Bus systems with other M-Bus interface supporting timecritical data (alarm protocol) and using communication status bit.
The M-Bus Master normalizes the M-Bus water meter with an SND_NKE and the M-Bus water meter acknowledges
successful receipt of the message by means of an ACK. An SND_NKE to primary address 253 will deselect the M-Bus
water meter, if it was selected by means of secondary or enhanced secondary addressing.
The M-Bus Master wishes to send data to the M-Bus water meter, or to select/deselect the M-Bus water meter via
secondary or enhanced secondary addressing. The M-Bus water meter acknowledges successful receipt of the
SND_UD telegram by means of an ACK. The acknowledgement (ACK) just means that the M-Bus water meter has
received the telegram successfully in the Data Link Layer and is as such no guarantee that the M-Bus water meter
has accepted the contents of the Application Layer.
Therefore, when receiving an SND_UD command with a new baud rate, the M-Bus water meter will acknowledge
receipt by means of an ACK, even though it ignores the contents, as the M-Bus water meter automatically detects
the baud rate on receipt.
flowIQ® 2101/3100 indicates in the display, and in the wired M-Bus datagram, if a special state in the meter, called
info codes, are present:
DRY: Meaning that the meter is not water filled, in this case nothing is measured.
REVERSE: Meaning that the water is flowing in the wrong direction in the meter.
LEAK: Meaning that the water has been running for more than 24 hours.
BURST: Meaning that the water flow is constantly high for more than 30 minutes.

The info code will disappear from the display and from the wired M-Bus datagram, when the condition that
initiated it disappears. Info codes initiate the Temporary error (bit 4) in the status field.
flowIQ® 2101/3100 info codes are mapped to the error bit ‘Temporary error’ (bit 4) when any info code is active.
Further, the ‘Power Low’ (bit 2) in the status field is set, when battery power is low.
The ‘Status field’ in the M-Bus data header can have one of the following values, or the sum of more values:
•
Temporary Error (Bit 4) is set when one of the info codes is active in flowIQ® 2101/3100.

The datagram in flowIQ® 2101/3100 M-Bus water meter has a fixed data content.
Previously, Kamstrup has placed a number of special registers like configuration values in the manufacturer
specified part of the telegram. This has required quite extensive knowledge of the meter in order to decode and
format these data correct.
In order to be able to decode special data registers in an easier way, Kamstrup has taken the approach to define a
number of manufacturer VIF extensions – so called VIFE. The outcome is that most reading systems can show the
special registers in clear reading.
Below an example showing manufacturer specified data vs. Manufacturer specified VIFE:

The datagram is fixed and cannot be changed. The datagram from flowIQ® 3100 large meter versions differs slightly
from the one in flowIQ® 2101, because these large meters do not measure the water temperature.

The daily flow and temperatures are the actual daily minimum, average or maximum values logged from midnight
until the present reading time.
The loggers in the flowIQ® 2101/3100 can only be read with an optical reading head, the optical eye in the meter
and the program LogView.
Following parameters can be sent to the M-Bus water meter, in order to change the configuration of the
flowIQ® 2101/3100:
• Primary M-Bus address
• Date and time
Selection of the M-Bus water meter via secondary address or enhanced secondary address, and application
select/reset is obtained via SND_UD telegram from the M-Bus Master to the M-Bus water meter. Selection of
device for secondary addressing is made by CI-field = 52h, and application select/reset by CI-field = 50h.

Note:
The M-Bus water meter will also reply with an acknowledgement (ACK) when receiving a set of baud rate telegrams
(CI-field = B8h... BFh), but will ignore the contents, as the M-Bus interface is furnished with automatic baud rate
detection.
The individual datagram for writing data in the M-Bus water meter are shown subsequently.
•
A dedicated register in the flowIQ® 2101/3100 is used for storing the primary address. This register may be
overwritten with a new M-Bus primary address using the datagram format below.
During the ordering process the primary address for each meter can be specified. Normally it is the last 2-3
digits of the customer number.

•
To synchronize the time in the meter towards a main application real time clock, the time and date may be sent to
the flowIQ® 2101/3100 using the datagram format below.
To avoid disturbing the internal loggers, setting the time must be done in due time before or after an hour shift.
Typically the date/time is set once each 24 hour.
As flowIQ® 2101/3100 uses two digits to indicate year (00... 99), the flowIQ® 2101/3100 M-Bus always sends
information concerning year as 2000... 2099 (bit HY1:HY0 always = 01 in ‘Date and time record’, VIF = 6Dh and DIF
= 04h, compound data type F).
See EN13757-3 Annex A ‘Coding of data records’ for details on how to decode the Date/Time data type.
In connection with application reset the flowIQ® 2101/3100 M-Bus water meter returns an ‘ACK’. Nothing further
happens and nothing is reset.

A target value may read as zero, until passing the set target date.
Reply from the M-Bus water meter (RSP_SKE) on request for communication status from M-Bus Master (REQ_SKE):
The ACD (Access Demand) and DFC (Data Flow Control) status bits (bit 5 and bit 4 respectively) in the C-field will
always be = 0 in the reply, which means that the M-Bus water meter does not have any time-critical (alarm) data
to send and has no buffer overflow, as the M-Bus water meter does not support time-critical data (alarm protocol).
But the (empty) RSP_SKE reply to REQ_SKE request ensures, that the M-Bus water meter will function in M-Bus
systems with other M-Bus interfaces, supporting time-critical data (alarm protocol) and using communication
status bit.

The VIF codes contain both unit and scaling factor for the record value. The VIF codes for volume and flow will, as
far as possible, reflect the display reading in the water meter as regards unit, decimal point and number of
decimals.
Thus, the VIF codes for these data values will vary depending on the configuration of the flowIQ® 2101/3100.
The relevant VIF codes are listed in the table below.
