Code table Diagnostics High byte (no. 6)

With the 2 byte communication object Diagnostics, the information about a DALI device or a lighting group
is provided on the KNX. The communication object no. 6 Diagnostics is updated via the communication
object no. 7 Request diagnostics and sent on the KNX.
For further information, see:
The 2 byte communication object no. 6 can be divided into two 1 byte values:

High byte (bit 8...15)

Low byte (bit 0...7)
In the low byte, the information of the communication object no. 7 Request diagnostics is repeated. The
high byte specifies the DALI devices or the lighting group.
The following code table shows the relationship between the value of the communication object of the high
byte and the status of the DALI system with its DALI devices or the lighting group.
The information in bit 7 is dependent on whether the information is device-based or group-oriented. In the
case of the device-based display, bit 7 contains information on whether the device is available, i.e.,
whether it reports to the DALI. In the case of group-oriented display, bit 7 contains information indicating if
the fault messages are blocked.
