5.1.10 Consumed energy differential counter overflow value
The
“Consumed energy differential counter overflow value”
parameter is used to set the maximum value
of the differential active energy counter; in fact, unlike the primary counter, it is possible to set the maximum
count value - i.e. the value beyond which the differential counter is in an overflow condition.
Depending on the value set for the
“Consumed energy counter format”
parameter, the values that can be
set for this item will be different:
If the format is
watthour (Wh)
, the format (Data Point Type) of the
Consumed active energy differential
counter
communication object is 13.010 DPT_ActiveEnergy, and the values that can be set for the
parameter
are:
-
from 0
to
2147483647 (default value)
watthour, in steps of 1
If the format is
kilowatthour (kWh)
, the format (Data Point Type) of the
Consumed active energy
differential counter
communication object is 13.013 DPT_ActiveEnergy_kWh, and the values that can
be set for the parameter are:
-
from 0
to
2147483647 (default value)
kilowatthour, in steps of 1
5.1.11 Consumed energy differential counter sending condition
The
“Consumed energy differential counter sending condition”
parameter defines the conditions for
sending the current differential counter value. The values that can be set are:
-
sending on request
-
sending on variation
(default value)
-
sending periodically
-
sending on variation and periodically
Selecting
sending on variation
or
sending on variation and periodically
visualises the
“Consumed energy
differential counter variation for sending”
parameter, whereas selecting
sending periodically
or
sending
on variation and periodically
visualises the
“Consumed energy differential counter sending period
(minutes)”
parameter.
If
sending on request
is selected, no new parameter is enabled because the differential counter value is not
sent spontaneously by the device; only in the case of a status read request (e.g. from a supervisor) will it send
the user a telegram in response to the command received, giving information about the current value of the
differential counter.
If the sending condition of the differential counter is different from
sending on request
, the value of the counter
is sent after a BUS voltage reset in order to update any connected devices.
5.1.12 Consumed energy differential counter variation for sending
The
“Consumed energy differential counter variation for sending”
parameter is visible if the differential
counter value is sent with a change. It defines the minimum count variation (in relation to the last value sent)
that causes the new value to be spontaneously sent. The values that can be set are:
-
10 Wh
-
20 Wh
-
50 Wh
(default value if the counter format is “Wh”)
-
100 Wh
-
200 Wh
-
500 Wh
-
1000 Wh
(default and ONLY value that can be set from the database if the counter format
is “kWh”)
