6
profiles can be defined for each day in a week and specified holidays.
Likewise, 8 different season profiles can be defined and 4 different
weekly profiles can be defined for seasons. Different tariffs can be
assigned for each day in a week. Unlimited holidays can be defined
for the next 10 years.
1.3.3. Passive Tariffs (Optional)
Passive tariffs are used in order to change the used tariffs structure
after a certain date. LSM meter reading software is used to create and
write the passive tariffs structure, in the same format as the active
advanced tariffs structure. In addition to the passive tariffs structure,
the activation date needs to be written for the passive tariffs to be ac-
tivated when required. Once the time of activation comes, the passive
tariffs are overwritten to the active tariffs in the memory of the meter,
and the passive tariffs data and the activation date are deleted.
1.4. Maximum Demand
The maximum demand is stored as the maximum demand of the
previous month, at the end of each billing period. Then, this para-
meter is cleared by the meter. This process is done automatically
at the end of month, if the maximum demand is not reset manually
within that month. LSM series meters stores the maximum demand
and date and time of the maximum demand for the last 24 months.
The current value of maximum demand and its date and time can be
viewed on LCD or read out using the OBIS codes 1.6.0 (import) and
2.6.0 (export). The previous months’ information can be read out with
the OBIS codes from 1.6.0*1 to 1.6.0*24 (import) and from 2.6.0*1 to
2.6.0*24 (export). The maximum demand information is read in the
following format:
(000.000*kW)(YY-MM-DD,HH:mm)
1.5. Load Profile
LSM meters store the load profile data in its non-volatile memory for
the past 90 days with 15 minute period, 180 days for 30 minute period
and 360 days for 60 minute period by default. The load profile memory
can be extended by request to support storing of over 20 years of
load profile data.
The meter recognizes the following format:
<SOH>R5<STX>P1(YYMMDDHHmm;YYMMDDHHmm)()<ETX><BCC>
and responds in the following format:
<STX>R5(XX)
(YYYY-MM-DD)(HH:MM)(XXXXXX.XXX*kWh)
(YYYY-MM-DD)(HH:MM)(XXXXXX.XXX*kWh)
...
<ETX><BCC>
1.6. Writing Parameters of the Meter
Authorized personnel can write only the following parameters to the
meter using the meter password:
