M-Bus Master MultiPort 250D

5 M-Bus addressing

Primary, secondary and enhanced secondary addressing are supported. The master's integrated collision detector enables wild
card search for meters in connection with secondary and enhanced secondary addressing.
Using wild card search, one or several of the digits of the meter's address are replaced by wild cards when searching for
meters.
5.1

Primary addressing

(001-250)
Each meter must have a unique primary address between 001 and 250. If more than one meter have the same address, a
collision will occur and the meters cannot be read.
Kamstrup M-Bus modules automatically use the last 2-3 digits of the customer number as their primary addresses.

5.2 Secondary addressing

(00000001-99999999)
Secondary addressing uses the last 8 digits of the meter number as M-Bus ID.
Kamstrup MULTICAL® meters use the customer number as their secondary addresses, which makes it possible to change the
secondary address.
5.3

Enhanced secondary addressing

(00000001-99999999)/(00000001-99999999)
The meter's serial number is used for enhanced secondary addressing. A meter's serial number is unique and cannot be
changed after production.
