Examples: Ballast 3 on channel 2 has the instance number 103, Group 5 on channel 1 has
the instance number 1005, and channel 4 has the instance number 2300.
In compatibility mode the instance number is 0x0ABBCC, where “A” is 0 for the objects
associated with DALI devices and 1 for the objects associated with DALI groups, and 2
with DALI channels, “BB” is the DALI interface number (0-3) in hex, and “CC” is the
DALI device number (0-63) or the DALI group address (0-15) respectively in hex.
Examples: Ballast 3 on channel 2 has the instance number 0x000303 (771), Group 5 on
channel 1 has the instance number 0x010205 (66053), and channel 4 has the instance
number 0x020300 (131840).
Object_Name (Read-Only)
This property holds the name of the lamp/group/channel. It can be changed via the Web-UI.
Object_Type (Read-Only)
The value of this property is ANALOG_OUTPUT (1).
Present_Value (Read/Write)
This property, of type REAL, indicates the linearized percentage (0..100.00%) of the
device’s desired light output; 0 being off, 1 being dimmest, 100 brightest. It is used to dim
the corresponding DALI ballast, group, or channel.
Depending on the
Dim_Mode
property, a write to this property results in a DALI “DIRECT
ARC POWER CONTROL” command (fade) or a series of UP or DOWN commands to the
device, group or channel respectively.
Description (Read/Write)
This property can be configured via BACnet. It serves documentation purposes only.
Device_Type (Read-Only)
This property contains the DALI device type (e.g. “
low voltage halogen lamp
”) for objects
mapping to DALI devices, “
DALI group
” for objects mapping to DALI groups and “
DALI
channel
” for objects mapping to DALI channels.
Status_Flags (Read-Only)
Of the four flags the flags IN_ALARM, FAULT, and OUT_OF_SERVICE are linked to the
state of the corresponding properties
Event_State
,
Reliability
and
Out_Of_Service
as
described by the standard.
OVERRIDDEN
Logical TRUE (1) if the associated DALI channel is controlled via
the button interface (see Section 4.5.2), FALSE otherwise.
Reliability (Read-Only)
The
Reliability
property for this object type may have any of the following values:
NO_FAULT_DETECTED
No fault was detected.
NO_OUTPUT
A lamp failure was detected (for groups and channels if
at least one lamp failure in the group/on the channel was
detected).
