The updated or new meter mapping file will be available under
Active meter mapping
section.
See section 5.3.3 for more information about how to create or modify meter mapping files.
To delete a meter mapping:
•
Click the trashcan icon (
) in the
Options
section.
5.3.2 Meter types in use
This section shows available/installed meters in the product. By clicking the download icon ( ), a
template file is downloaded which serves as a good starting point for creating the OBIS meter
mapping file. It contains all M-Bus fields available from the particular meter in the correct
template format, ready to use as a meter mapping file.
Please note that the CMe3100 must have done at least one readout from the meter before
the template file is downloaded, otherwise the M-Bus value information will be empty.
5.3.3 Create or modify a meter mapping file
To create a new meter mapping file, first use download for the appropriate meter as described in
section 5.3.2. To modify an existing meter mapping file, download it in the section
Active meter
mappings
.
The mapping files are in JSON format and can be edited in a text editor, preferably one that has
support for highlighting JSON.
Update the contents of the file, by connecting OBIS codes with corresponding M-Bus keys
(VIF/DIF combinations). All OBIS codes must be configured for each entry in the mapping, in
order for the value to be available over DLMS.
The mapping can be made for a specific meter or made generic by setting manufacturer to “all”
and/or version to 0. It is also possible to map several M-Bus keys, even from meters with
different versions or manufacturers, to the same OBIS code. This allows you to create mapping
files that handles for example meters which has differences between versions and/or
manufacturers.
When using a generic mapping file it is also possible to combine it with other meter mapping files
for specific manufacturers and/or a specific versions if they need to be handled in a different way.
This is accomplished by the way the mapping files are applied, they use a predefined matching
order as shown below. The first file that matches the criteria will be used. A meter mapping file
which has manufacturer and/or version set to a specific value will be used instead of a generic
mapping file if the manufacturer and/or version is matching for a particular meter.
1. Matching type, manufacturer and version.
2. Matching type, manufacturer and generic version.
3. Matching type, generic manufacturer and generic version.
