5.1.13 Consumed energy differential counter sending period (minutes)
The
“Consumed energy differential counter sending period (minutes)”
parameter is visible if the
differential counter value is sent periodically. It defines the frequency for spontaneously sending telegrams
indicating the current differential counter value. The values that can be set are:
-
from 1 to 255 in steps of 1
(default value 15)
In the event of a supply voltage failure, the differential counter value is saved in a non-volatile memory so it
can be reset when the power supply returns.
5.1.14 Start/stop consumed energy differential counter from bus
Unlike the primary counter, the differential counter can be started/stopped via a BUS command; this makes it
possible, for example, to measure the consumption within a specific time band managed by another KNX
device. The
“Start/stop consumed energy differential counter from bus”
parameter enables this function,
making the dedicated communication object visible. The values that can be set are:
-
disable
(default value)
-
enable
Selecting
enable
visualises the
Trigger consumed active energy differential counter
(Data Point Type:
1.010 DPT_Start
) communication object, for receiving the count start (“1”) / stop (“0”) commands.
Following an ETS download, the count is started by default, regardless of whether or not its start/stop has
been enabled via the BUS.
Via the
Overflow consumed active energy differential counter
(Data Point Type: 1.002 DPT_Bool)
object,
the device signals the overflow of the differential counte
r. When an overflow occurs, a value of “1” is sent; a
value of “0” is sent when the counter is reinitialised.
The device can use the
Reset consumed active energy differential counter
(Data Point Type: 1.015
DPT_Reset) communication object, the device can receive the differential counter reinitialisation commands
that bring the counter back to 0 (initial value); a value of “0” is ignored, whereas when the value “1” is received,
the differential counter is reset at "0" and the
Overflow consumed active energy differential counter
object
is set at “0”.
PARAMETERS RELATING TO “PRODUCED ACTIVE ENERGY”
5.1.15 Produced active energy counter
The
“Produced active energy counter”
parameter can be used to activate the count of the active energy
produced and define the format of the communication object used to send the counter value.
The values that can be set are:
-
disabled
(default value)
-
enable primary counter
-
enable primary and differential counters
If
enable primary counter
is selected, the
“Produced energy counter format”
,
“Produced energy primary
counter init value”
,
“Reinitialize produced energy counters”
, and
“Produced energy primary counter
sending condition”
parameters are displayed, along with the
Produced active energy primary counter
communication object.
If
enable primary and differential counters
is selected, not only the parameters/communication objects listed
previously (in relation to the primary counter) are displayed but also the
“Produced energy differential
counter overflow value”
,
“Start/stop produced energy differential counter from bus”
,
and
“Produced
