Individual Control
Each lamp can be controlled individually via the switch input network variable
nviLAValue
of the lamp actuator object. Any new value received is transmitting to the corresponding
DALI lamp in fading mode (configuration property
nciFadeTime
is used).
Group Control
Lamps belonging to a group can be controlled together by the following network variables
of the group actuator object.
nviGPValue
:
This network variable has the same functionality as
nviLAValue
but
controls a whole group. Any new value received is transmitting to the DALI lamps
in the group using fading mode (configuration property
nciFadeTime
is used).
nviGPSetting
:
Using this input network variable of type SNVT_setting dimming
devices can change the brightness relatively. By
function
= SET_UP or
function
=
SET_DOWN the light is dimmed relatively by the amount defined in the
corresponding
setting
field. By
function
= SET_STOP ongoing fades are stopped.
When the light is switched off by
function
= SET_OFF, the last light level is saved
temporarily. When the light is switched on again (function = SET_ON) the
remembered light level is restored. An absolute light level can be set by
function
=
SET_STATE. The corresponding
setting
field defines the target light level. The
light value is changed in ramping mode (configuration property
nciFadeRate
is
used).
nviGPScene
:
Using this input network variable of type SNVT_scene up to 16
DALI scenes can be saved and recalled. The command SC_LEARN stores the
current light levels of all lamps of the group in the specified scene number. By a
SC_RECALL command previously stored scenes can be recalled. Scenes can be
deleted by a SC_RESET command. When a new scene is selected the lamp values
are adjusted in fading mode (configuration property
nciFadeTime
is used).
Channel Control
All lamps on the same DALI channel can be controlled together by the following network
variables of the channel actuator object.
nviCHValue
:
This input network variable works in the same way as
nviLAvalue
and
nviGPvalue
but affects all lamps on a channel.
nviCHSetting
:
This input network variable works in the same way as
nviGPSetting
but affects all lamps on a channel.
8.2.5.2 Maximum and Minimum Light Level
For a dimmable lamp the maximum and minimum light level of a lamp can be configured
via the configuration properties
nciMinLevel
and
nciMaxLevel
of type SNVT_switch.
For a non-dimmable lamp set
nciMinLevel
=
nciMaxLevel
= 100%.
8.2.5.3 Timing Parameters
Figure 210 shows the behavior of the lamp actuator if the light is switched on/off via one of
the switch (
nviLAValue, nviGAValue, nviCHValue
) or via one of the setting input network
variables (
nviGASetting, nviCHSetting
). When the ON command is received, the lamp is
switched to the specified value after the time
nciOnDelay
has expired. When the lamp is
already on and a new ON command is received the lamp is switched to the new value
