This communication object is enabled if, in the
group/device code enable encoded fault message is parameterized with the Yes option.
Via this communication object, the DLR/S transfers the status of a fault of every lighting group or of each individual DALI
device to the KNX. It can be parameterized whether the bit combination corresponds to a lighting group 0...15 (group-
oriented) or an individual DALI device 0...63 (device based).
Bit 0...5
Bit 6
Bit 7
A logical 1 indicates the fault.
The values read via the communication object can be interpreted as follows:
Group oriented setting:
No fault
Lamp fault
Ballast fault
Device oriented setting:
No fault
Lamp fault
Ballast fault
For further information, see:
The telegrams are sent immediately after detection of the fault. Should several faults occur at the same time, the telegrams
are sent consecutively on the KNX. If a fault is remedied, this will also be indicated on the communication object Fault
group/device code (no. 19). The information will be retained in the communication object until the fault state changes or a
telegram with the value 1 is received on the object Request status values (no. 10). In this case, the fault state of the DALI
device or the lighting group is displayed as contained in the communication object Group/device fault (no. 21).
Note: The detection of the error state can take up to 90 seconds, depending on the situation.
Function
Fault group/device code
= Contains the binary number (0...15 or 0...64).
This number added to 1 corresponds to the number of the faulty lighting group or the faulty DALI
device.
