In Operation
General
1 bit
DPT 1.002
C, R, T
The communication object is enabled if
send value 0/1 cyclically
is selected for the parameter
Send communication object
"In operation"
in the
General
parameter window.
In order to regularly monitor the presence of the device on the KNX, an in-operation monitoring telegram can be sent
cyclically on the bus.
As long as the communication object is activated and has a group address has been assigned, it sends a parameterizable
in-operation telegram cyclically.

C, W
If this communication object receives a telegram with the value 0 or 1 (depending on parameterization), the measured
values of communication objects 2-7 are sent.

The device uses this communication object to report whether the rated current has been exceeded. If the rated current is
exceeded for 10 seconds then a telegram with the value 1 is sent. The value is immediately reset to 0 when the rated
current falls below the limit value. The object value is sent when there is a change, and on request.
Telegram value:
0 = Bus current < Rated current I
