Section 5 BUFFER MEMORY
5.5.7 Communication error flag (Un\G16002)
Result of internal communication of RE81WH is stored.
(1) Details of stored data
(a) Storage format
Data is stored as 16-bit signed binary in the buffer memory.
・Data range: 0, 1 (0: no error, 1: error)
(b) Update timing
It will be updated every measuring cycle. For measuring cycle, refer to "5.2.12".
(2) Precautions
Where the data is "1: error", the waveform data of voltage of the period of measured data acquisition clock
is not stored into the buffer memory.
5.5.8 Phase 1 current waveform data 1 to 300 (Un\G16004 - Un\G16603),
phase 3 current waveform data 1 to 300 (Un\G20004 - Un\G20603)
Waveform data of each phase current is stored.
Stores data of the number of the waveform data of current (Un\G16001) from waveform data 1.
(1) Details of stored data
(a) Storage format
Data is stored as double-word 32-bit signed binary in the buffer memory.
・Data range: -999999999 to 99999999 (-999999.999 to 99999.999 A)
(b) Storage range
The range differs according to the period of measured data acquisition clock.
Refer to "" as to details.
(c) Unit
A *Unit is fixed.
-3
×10
(d) Update timing
It will be updated every measuring cycle. For measuring cycle, refer to "5.2.12".
5.5.9 Multiplying factor of voltage and current waveform data (Un\G22000)
The multiplying factor of waveform data of voltage and 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.
