o M-Bus Port: This folder contains the remote M-Bus data points, which are
used on the device.
10.5.4 Network Port Folders
The M-Bus network port folder on the device has the same structure of sub-folders as the
other network port folders in Section 6.2.2. Currently only the Datapoints folder exists for
the M-Bus network port.
10.5.5 M-Bus Properties
Apart from the common data point properties discussed in Section 6.2.4 the data points of
the M-Bus technology have additional properties:
Storage Number: This property defines the M-Bus storage number of the data point.
This number can also be specified by the manufacturer using a DIF/DIFE combination.
Tariff: This property defines the tariff of the M-Bus data point. This number can also
be specified by the manufacturer using a DIF/DIFE combination.
Subunit: This property defines the subunit of the M-Bus data point. This number can
also be specified by the manufacturer using a DIF/DIFE combination.
Function Field: This property defines the function field of the M-Bus data point.
Possible values for this property are instantaneous value, maximum value, minimum
value and value during error state. This number can also be specified by the
manufacturer using a DIF/DIFE combination.
Data Coding: This property defines how the value for this data point is coded. The
information is not relevant for input data points but it is mandatory for output data
points. Possible values for this property are instantaneous value, maximum value,
minimum value and value during error state. This number can also be specified by the
manufacturer using a DIF/DIFE combination.
VIF/VIFE: The VIF and VIFE (Value Information Field and VIF Extension) specify
the counter type and its scaling. When the most significant bit of a VIF or VIFE is set,
another VIFE follows. Up to ten VIFEs can be specified. When this combination is
entered, also the M-Bus counter type and the unit are updated according to the
VIF/VIFE combination.
M-Bus Counter type: This information is derived from VIF/VIFE. It informs about
the type of the data point value (e.g. Energy counter value or operating time).
M-Bus Device Name: This property shows the name of the M-Bus device the remote
data point is connected to.
M-Bus Device Address: This property shows the address name of the M-Bus device
the remote data point is connected to.
M-Bus Pollgroup: Each M-Bus input data point is attached to a poll group. If more
than one poll group is available, the poll group can be selected. This property is not
shown for output data points.
10.6 M-Bus Workflow
This section discusses the workflows for setting up an M-Bus environment. The network
can either be set up online using the network scan function or also offline by either setting
up the devices and data points manually or by using M-Bus device templates. The change of
primary addresses and Baud rates can only be done online.
