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: 
 

-

(Data  Point  Type:

) 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”.

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:
