7.3 Maximum demand registers
G1B meter detects and stores the values of maximum demand over a billing period in a
separate register. Meter can register cumulative maximum demands as well. Maximum
demand values of each tariff time zone are stored in maximum demand register with their
respective timestamps:

Demand tariff number M=[0T6], “0” - max. demand off all the tariff zones.
Maximum demand is displayed automatically in three steps (see
Figure

): [1] maximum demand value; [2] date of maximum demand [YY-MM-DD]; [3] time
of maximum demand [hh:mm].

8 Data profiles
Meter contains the following data profiles:
•
Billing profile;
•
Load profile;
•
Second load profile (network profile);
•
Wired M-bus load profile;
•
Event log.
Each data profile is organized as a FIFO (First-In-First-Out) buffer in non-volatile memory.
When the buffer is full the oldest entry is overwritten by the most resent entry.
8.1 Billing profile
Billing profile stores values of all energy registers and values of all maximum demand
registers. Values are written to billing profile at each billing period reset. Billing period reset is
done:
•
automatically (periodically at predefined date and time),
•
manually (by pressing sealed push-button, when LCD operates in main automatic data
scroll cycle),
•
remotely (via communication interface).
Automatically it may be reset at parametrized periods (up to 6 different periods). Possible
cases for every one of these 6 periods:
•
