Page 4: Introduction
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. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -
Page 5: Physical Properties
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 M- Bus water meters. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -

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. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -

Page 13: M-Bus Slave To M-Bus Master
The M-Bus water meter checks the message, and if it is correct, the M-Bus water meter returns with an RSP_UD, which is meter data packed according to the M-Bus format for RSP_UD. An example of a RSP_UD datagram can be viewed later in the manual. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -
Page 14: Req_Ud1 -> Ack
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. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -

No info code Power Low on battery Temporary Error Power Low and Temporary Error 5.7.2 Temporary error Temporary Error (Bit 4) is set when one of the info codes is active in flowIQ® 2101/3100. Kamstrup A/S · Technical Description · 55121944_A1_GB_08.2016... -
Page 16: Datagram
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. -
