Energy and energy by tariff measurements
Most energy values are available in both signed 32-bit integer and floating point format. The SNVT is
appended with _l for 32-bit integer values and _f for floating point values.
appended with _l for 32-bit integer values and _f for floating point values.
For example, the SNVTs for total active energy import are as follows:
•
32-bit integer: SNVT_elec_kwh_l
•
Floating point: SNVT_elec_whr_f
The energy and energy by tariff measurements listed below are preserved through power failures.
nvoErrors
SNVT_state
Device error status
Error bitmap: each bit of the bitmap provides error information about
the device. If value of the bit = 1, that error is active.
Bit0 = Code 101: EEPROM error
Bit1 = Code 102: No calibration table
Bit2 = Code 201: mismatch between frequency settings and
frequency measurements
Bit3 = Code 202: mismatch between wiring settings and wiring inputs
Bit4 = Code 203: phase sequence reversed
Bit5 = Not used
Bit6 = Code 205: Date and time have been reset due to a power
failure
Bit7 = Not used
Bit8 = Code 207: Abnormal internal clock function
Bit9 = Internal data bus communications error
Bit10 - 15: Not used
