Type

Description

 

 

 

 

 

 

 

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

 

nvoErrors

SNVT_state

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

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.

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.
