Section 5 BUFFER MEMORY
5.3.18 Electric power demand (Un\G404, 405)
Stores the electric power that is measured based on the moving average for the duration of time configured in
the electric power demand time (Un\G4).
(1) Details of stored data
(a) Storage format
Data is stored as double-word 32-bit signed binary in the buffer memory.
If the power is negative, represents the regenerative power.
・Data range: -999999999 to 999999999 (-999999.999 to 999999.999 kW)
* Restrictions for measured data including resolution and measuring range, refer to "3.4.1".
(b) Unit
kW *Unit is fixed.
-3
×10
(c) Update timing
It will be updated every measuring cycle. For measuring cycle, refer to "5.2.12".
5.3.19 Maximum electric power demand (Un\G420, 421),
minimum electric power demand (Un\G428, 429)
Stores the max./min. values of the electric power demand.
(1) Details of stored data
(a) Storage format
Data is stored as double-word 32-bit signed binary in the buffer memory.
If the power is negative, represents the regenerative power.
・Data range: -999999999 to 999999999 (-999999.999 to 999999.999 kW)

(c) Update timing
It will be updated every measuring cycle if it exceeds the electric power demand max. value or goes under
the electric power demand min. value.
For measuring cycle, refer to "5.2.12".
5.3.20 Year of time of max. electric power demand (Un\G422),
month and day of time of max. electric power demand (Un\G423),
hour and minute of time of max. electric power demand (Un\G424),
second and day of the week of time of max. electric power demand (Un\G425),
millisecond of time of max. electric power demand (Un\G426),
year of time of min. electric power demand (Un\G430),
month and day of time of min. electric power demand (Un\G431),
hour and minute of time of min. electric power demand (Un\G432),
second and day of the week of time of min. electric power demand (Un\G433),
millisecond of time of min. electric power demand (Un\G434)
Stores year, month, day, hour, minute, second, day of the week and millisecond of time of maximum value of
electric power demand (Un\G420, 421) and minimum value of electric power demand (Un\G428, 429) were
updated.
