NOTE: energy registers (see section 7.1) as well as demand and energy values in load profile and billing
profile are stored with the same resolution, therefore monthly billing data is always equal to sum of load
profile data.
NOTE: On special request, the capacity of non-volatile memory can be reassigned in different proportions for
load profile, billing profile and event logs.
8.3 Second load profile
On special request, G1B meters may have second load profile (Network profile) with independent
integration period [1T60] minutes, where the following network values can be captured in
additional channels. Network profile (OBIS 99.2.0) stores 5 quantities presented in Table 8-4.
Table 8-4 Second load profile data
Average values
11.5.0 Average current [A]
12.5.0 Average voltage [V]
71.5.124 Average current THD
72.5.124 Average voltage THD
14.5.0 Average frequency [Hz]
Storage interval (in days) of second load profile (network profile) depends on integration period
chosen. Integration period may obtain values of 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60 minutes.
Second load profile data can be readout via all available communication interfaces. Second load
profiles possess storage for 15 days in case of 10 minutes integration period.
8.4 Wired M-Bus load profile
The wired M-Bus interface is employed to collect data from up-to four multi-utility (water, gas)
meters. Electricity meter reads multi-utility (water, gas) billing data at certain intervals and store in
M-Bus load profile. Along with consumption data, other details are stored, such as meter serial
number and manufacturer's information. G3B meter may store up to 168 hourly values (up to 1
week) of each of four multi-utility meters in load profile.
8.5 Event log
Meter contains separate event logs (i.e. independent FIFO buffers) to store information about
various events. Event log data can be readout via all available communication interfaces.
