6.3.3 Reactive energy (consumption lag) (Un
\
G106, 107)
Delayed consumption of the reactive energy is stored.
(1) Details of stored data
(a) Storage format
Data are stored as double-word 32-bit signed binary in the buffer memory.
- Data range: 0 to 999999999
*For restrictions for measured data including resolution and measuring range, refer to section
4.2.1.
(b) Unit
Unit can be determined by the electric energy and the multiplier of the reactive energy
(Un
\
G100), as shown below.

(c) Update timing
It will be updated every measuring cycle (250 ms).
6.3.4 Periodic electric energy 1 (Un
\
G114, 115), periodic electric energy 2 (Un
\
G116, 117)
Stores the periodic electric energy 1 and periodic electric energy 2. The periodic electric energy of the
consumption side is measured.
For specific usage procedures for the periodic electric energy, refer to section 4.2.2.
