Meter status information

You can read the following network variables to obtain configuration and status information about the meter. For information on configuring the meter, see the sections on meter configuration properties and the LonWorks plug-in.

Network variable label	SNVT / UCPT type	Description
Basic information and meter configuration

Alarm status
nvoAlmStatus	SNVT_count	Alarm status (only Bit 1 is used): 0 = Alarm is inactive 1 = Alarm is active
nvoAlmUnAckState	SNVT_count	Acknowledgement status (only Bit 1 is used): 0 = historic alarm is acknowledged by the user 1 = historic alarm is unacknowledged by the user
nvoAlmLastTime	SNVT_time_stamp	Timestamp of last alarm (DD/MM/YYYY hh:mm:ss)
nvoAlmLastValue	SNVT_power_f	Value at last alarm
