52: Total energy consumption value increased too much in a
short time.
1.10. Optional Integrated Features
1.10.1. Import-Export Energy Measurement
LSM series meters can optionally measure energy bi-directionally.
The measured export energy is recorded apart from the import tariffs
and added to the total export active tariff -T and the corresponding
export tariff from -T1, -T2, -T3, -T4. The export reactive consumptions
are also recorded separately from the import reactive consumptions
and added to the -Ri, -Rc export reactive tariffs. The export energy in-
formation can be viewed on the LCD following the related OBIS codes
(2.8.0, ..., 2.8.4, 7.8.0, 6.8.0). Export -T, -T1, -T2, -T3, -T4, -Ri (induc-
tive), -Rc (capacitive) consumptions have OBIS codes of 2.8.0, 2.8.1,
2.8.2, 2.8.3, 2.8.4, 7.8.0, 6.8.0 respectively. The export measurement
values are displayed with a negative (-) sign to the left (-T, -T1, -T2,
-T3, -T4, -Ri, -Rc).
Export measurement feature can be turned on by writing 1 or turned
off by writing 0 to 96.74.18 OBIS code. After export feature is disabled
or enabled, the past load profile data is erased. If export feature is
enabled, import and export consumptions are recorded; however, if
export feature is disabled, only the import consumption is recorded,
which significantly increases the maximum number of records the
load profile can hold compared to import-export.
1.10.2. RS485 Communication Port
In case there is only one meter connected to the data line, the meter
can be readout using the format “/?!CRLF” via RS485 protocol. On the
other hand, if multiple meters are connected to the same data line, the
meters can be read individually using the format “/?XXXXXXXX!CR-
LF” where XXXXXXXX is the serial number of the meter to be readout.
1.11.3. DLMS Communication
The meter supports DLMS Communication over communication ports.
1.10.4. PLC Communication
The meter can have an integrated PLC module to support PLC com-
munication. Then, it can be readout and controlled using a Data Con-
centrator(DC) and from LUNA Metrum remotely.
The PLC module uses CENELEC A band and DCSK modulation for
power line communication. It supports communication speed of up
to 2.5kbps.
No setup or connection is required for PLC communication on the
meter side.
1.10.5 RF Communication
The meter can have an integrated RF module to support RF commu-
