Schneider Electric iEM3100, iEM3300 Energy and energy by tariff measurements, Type Description

iEM3100 / iEM3200 / iEM3300 series user manual			Communications via LonWorks
	Network variable label	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
	nciMeterModel	SNVT_str_asc	Device model, stored as an ASCII string (for example, iEM3275)
		(SCPTpartNumber)
	nciMeterManf	SNVT_str_asc	Manufacturer name (Schneider Electric)
		(SCPToemType)
	nciSerialNumber	SNVT_str_asc	Device serial number
		(SCPTserialNumber)
	nciManfDateTime	SNVT_time_stamp	Date of manufacture
		(SCPTmanfDate)
			LonWorks firmware major version (for example, 2.xx)
	nciDevMajVer	SCPTdevMajVer	This variable functions with nciDevMinVer to provide the device’s
			LonWorks firmware version
			LonWorks firmware minor version (for example, x.34)
	nciDevMinVer	SCPTdevMinVer	This variable functions with nciDevMajVer to provide the device’s
			LonWorks firmware version

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.
