This group object is enabled if the Enable Group object "Fault addressed" parameter is set to Yes in the X Output: Fault
parameter window, p. 57.
This group object consists of two bytes. The High byte contains the fault status of the corresponding device or group.
The Low byte contains the device or group number and the information as to whether it is a status request or a sent status.
Via this group object, the gateway transmits the status of a fault on any group or any individual DALI device on the KNX.
The following numbering applies to the list below:
High byte
15
2
The bit number is identical to the exponent of the bit, e.g. number 2 corresponds to 2
Bit 0 to 5
Bit 6
Bit 7
Bit 8
Bit 9
Bit 10
A logical 1 indicates a fault.
The telegrams are sent as soon as the fault is detected. Should several faults occur at the same time, the telegrams are sent
consecutively on the KNX. If a fault is corrected, this is also signaled on the group object.
Note: Depending on the situation and parametrization, it can take some time to detect fault status.

Corresponds to the device address (0...63) or the number of a group (0...15)
Indicates the group/device reference. The value 1 indicates that the status value relates to a group,
the value 0 relates to an individual device (value 0).
The value 1 triggers a status feedback. If a telegram with a set bit 7 is received, it is interpreted as a
status request, and the switch status of the requested group or device is sent. When the answer is
returned, the value of bit 7 is reset to 0.
