Section 5 BUFFER MEMORY
5.3.4 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 "3.4.2".
(1) Details of stored data
(a) Storage format
Data is stored as double-word 32-bit unsigned binary in the buffer memory.
・Data range: 0 to 999999999
* When the stored data exceeds 999999999, stored data turns to 0 and continues measuring.
* Restrictions for measured data including resolution and measuring range, refer to "3.4.1".
(b) Unit
Unit can be determined by the multiplying factor of electric energy and reactive energy (Un\G100), as
shown below.
Multiplying factor of electric

-1
(c) Update timing
It will be updated every measuring cycle. For measuring cycle, refer to "5.2.12".
5.3.5 Multiplying factor of current (Un\G200)
The multiplying factor of the electric current is stored.
(1) Details of stored data
(a) Storage format
Data is stored as 16-bit signed binary in the buffer memory.
・Data range: -3 (fixed)
(b) Update timing
Because it is fixed at -3, there is no update.
