NANOVIP PLUS MEM:
INTERNAL MEMORY STRUCTURE
- Storage medium utilized: 0Serial Flash Memory
type NX25F080 (NEXCOM); 8 Megabit Serial
Flash Memories managed as 2048 sectors of 536
bytes.
- Type of data recorded: 4 different measure “families”
are recorded: RMS measures, MEM measures,
PEAK measures and finally measures THD + DC
Ripple + HARMONIC in pre-set intervals of 2
seconds or from 1-99 minutes.
Recording is carried out in “records” of 32 byte
defined as follows:
• RMS measures:
YY MM GG HH MM 0x01 24 Byte record data SS Check
YY MM GG HH MM 0x11
24 Byte record data SS Check
Where:
- YY, MM, DD, HH, MM are the year, month, day,
hour and minute when the record was recorded
(D1..D5);
- SS are the seconds (D31)
- 0x01 is the type of record: record 1, under record 0 (D6);
- Record data:
- Voltage measure (V)
(D7..D9: base + exp)
- Current measure (I) (D10..D12: base + exp)
- Active Power measure (Watt) (D13..D15: base + exp)
- Power Factor (D16..D18: base + exp)
- Reactive Power measure (var) (D19..D21)
- Apparent Power measure (VA)
(D22..D24: base + exp)
- Frequency (Hertz) (D25..D27: base + exp)
- D28..D30 not used
- D32 Modbus check-sum
- 0x11 is the type of record: record 1, under record 1 (D6);
- Record data:
- kWh positive (D7..D11: bcd format)
- kvarh positive (D12..D16: bcd format)
- kWh negative (D17..D21: bcd format)
- kvarh negative (D22..D26: bcd format)
- D27..D30 not used
- D32 Modbus check-sum
• MEM measures:
YY MM GG HH MM 0x02 24 Byte record data SS Check
Where:
- YY, MM, DD, HH, MM are the year, month, day,
hour and minute when the record was stored
(D1..D5);
- SS are the seconds (D31)
- 0x02 is the type of record: record 2, under record
0 (D6);
- Record data:
-Voltage saved in MEM mode (V) (D7..D9: base + exp)
- Current saved in MEM mode (I) (D10..D12: base + exp)
-Active Power saved in MEM mode (Watt)
(D13..D15: base + exp)
-Power Factor stored (D16..D18: base + exp)
-difference in Voltage (DV) with respect to the
value MEM
(D19..D21: base + exp)
-difference in Current (DI) with respect to the value
MEM
(D22..D24: base + exp)
-difference in Active Power (DWatt) with respect
to MEM
(D25..D27: base + exp)
-D28..D30 not used
-D32 Modbus check-sum
