Technical Description

5.9 Previous Values

At the end of a defined period, up to 50 configurable channels, which can contain
General
energy register values, input counter values and currency/CO
together with the time/date for the end of the period.
Previous values can be configured via Modbus and EQ-bus communication or
via the buttons on the meter.
Note –
Changing time/date into another period than the pending period will store
the current period and start a new one.
If a power fail occurs that lasts over the end of an ongoing period, the period will
be stored when the meter powers up again and a new period will start. If the
meter have lost time and date/time is not set when the meter powers up again,
previous values will enter a waiting state until time/date is set.
Storing periods
Previous values has 50 channels which can be configured individually via
com-munication. Each channel can store up to 200 periods.
The period length can be a day, a week or a month and can be configured
via Modbus and EQ-bus communication or via the buttons on the meter.
The period date and time is stored as end of period. For instance, if a period starts
2010.01.01 00:00.00 and ends 2010.01.02 00:00.00, then the stored period will
be 2010.01.02 00:00.00.
Stored periods can be read via communication or directly on the display.
If there is no free memory space available, the oldest period will be erased
to make room for the most recent one.
It is possible to erase all stored periods by sending a "Reset Previous
Values" command via communication.
