”
WMBUS” group commands for setting of messages
This group of commands serves for setting of Wireless M-BUS addressing of the WB169-430 module and for setting
of broadcasting parameters. There are following command:
mid
setting of device fabrication number (
”
M-BUS ID” – range 0 to 99999999)
manuf
setting of manufacturer code (
”
Manufacturer” - supplement of M-BUS address)
vers
setting of
”
addressing version” (
”
Version” - supplement of M-BUS address)
medium
setting of media code (
”
Medium” - supplement of M-BUS address)
info
setting device name
periode
setting of regular messages broadcasting period
power
setting of transmitting power (mW)
mode
setting of communication mode (1 - N1 mode, 2 - N2 mode)
chan
setting of frequency channel (choice from 7 options)
ekey
setting of encryption key (”.” - encryption disabled)
Variable
”
M-BUS ID”
is a serial number of the device in M-Bus standard identification system. The address is
”
read only” type for the WB169-430 module and cannot be changed. Assigned serial number of the module can be
displayed by
”
mid”
command (without parameter):
cfg#mid
MBUS ID : 00112233
cfg#
Variable
”
Manufacturer”
is an international code of device producer according to the M-Bus standard. The code
is
”
read only” type for the WB169-430 module, its value is
”
SFT” (Softlink) and it cannot be changed. Assigned
manufacturer code can be displayed by
”
manuf”
command (without parameter):
cfg#manuf
MBUS manufacturer : SFT
cfg#
Variable
”
Version”
is number of addressing version according to the M-Bus standard (each type and modification
of the device could have its own line of serial numbers). The code is
”
read only” type for the WB169-430 module
and cannot be changed. Assigned version number can be displayed by
”
vers”
command (without parameter):
cfg#vers
MBUS version : 101
cfg#
Variable
”
Medium”
is an international code of measured medium (water, energy, physical quantity..) according
to the M-Bus standard. The variable is editable and it is factory preset to 07 (”Water”). Current setting of the
medium value can be displayed by
”
medium”
command (without parameter). Medium parameter can be changed
by entering of required code of medium according to M-Bus standard (range: 0 to 255).
Example of medium code setting to ”02” value (electricity):
cfg#medium
MBUS medium : 7
cfg#medium2
MBUS medium changed from 7 to 2
cfg#
Note
: The full identification of the device in M-Bus standard systems is done by combination of four ID components:
”
M-BUS ID”,
”
Manufacturer”,
”
Version” and
”
Medium”. This combination must be unambiguous that means
there cannot exist two M-Bus devices worldwide, that have the same combination of all these parameters. If fixed
configuration of the address components used, producer of the device is responsible for unique setting of
”
read
only” address components for each device. If M-Bus address components are configurable, operator of the M-Bus
system can use serial number of connected meter in combining with its type, subtype and manufacturer. Using of
”
independent” addressing line is possible only in that case, if the operator of the system owns its M-Bus manufacturer
code and can assure that the identification of all operated devices under his code will be unique
