Domino
DFDALI
✗
The code 128 is required only to inform DFDALI when interrupt
a running function. For instance, to perform an Up function, the
code 125 must be sent: the brightness will increase until the
sending of code 128.
✗
The code 139 saves, in the non volatile memory of the bal-
lasts, the brightness level which will be automatically recalled
when a DALI or
Domino
bus failure occurs.
✗
The change from a brightness level to another one will be ex-
ecuted according to a ramp that can be set as desired by the
codes 140 to 173. The ramp value will be stored in the non
volatile memory of the ballasts, therefore a power failure does
not affect it.
Management by DFCP or by I/V table
The sending of commands or values to DALI devices can
be performed through a supervisor simply writing the
memory locations of DFCP related to the output of the in-
stalled DFDALI modules.
As option, or in addition, it is possible to send commands or
value from DFCP to the DALI module through proper equa-
tions as in the following example:
V1
= !(
I1.1
|
I1.2
|
I1.3)
AO2
= P(128)
V1
& \
P(125)
I1.1
& P(126)
I1.2
& \
P(50)
I1.3
where
I1.1
and
I1.2
are, for instance, the Up and Down
inputs and
AO2
is DFDALI module with address 2;
I1.3
will set the brightness to 50%. The specified value, at each
variation, will be transferred to the DALI output (
AO2
). At
the releasing of each pushbutton, the value is always set to
128 (no operation, but needed to inform the module about
the releasing of the buttons). In this case the described Up,
Down and Preset functions acts on all connected ballasts
(broadcast commands).
To get the same result on a ballast individually addressed,
it is easiest (even if not mandatory) to use the hexadecimal
format to write the equations, because the address of the
ballast has to be specified in the high byte of the channel:
V1
= !(
I1.1
|
I1.2
|
I1.3)
AO2
= P(
0x0180
)
V1
& \
P(
0x017D
)
I1.1
& P(
0x017E
)
I1.2
& \
P(
0x0132
)
I1.3
where
I1.1
and
I1.2
are the Up and Down inputs and
AO2
is DFDALI with address 2;
I1.3
will set the brightness
to 50%. The specified value, at each variation, will be trans-
ferred to the DALI ballast addressed 1. At the releasing of
each pushbutton, the value is always set to
0x0180
(no
operation, but needed to inform the module about the re-
leasing of the buttons).
A similar example follows to send command to a group of
ballasts:
V1
= !(
I1.1
|
I1.2
|
I1.3)
AO2
= P(
0x8180
)
V1
& \
P(
0x817D
)
I1.1
& P(
0x817E
)
I1.2
& \
P(
0x8132
)
I1.3
The specified value, at each variation, will be transferred to
the DALI devices assigned to group 1. At the releasing of
each pushbutton, the value is always set to
0x8180
(no
operation, but needed to inform the module about the re-
leasing of the buttons).
Of course the commands to DALI devices can be also sent
by DFCP through the using of the Scripts.
DFDALI module can however work without DFCP control-
ler, simply linking the desired commands to bus input
points (both real and virtual ones); for details about this
possibility, refer to the paragraph I/V Table.
Manual commands by the module
pushbutton
Near to the terminal block of DALI line, a pushbutton allows
the following functions: a short pulse will cause the com-
plete switching ON and OFF, while holding down the button
the brightness increases or decreases depending on previ-
ous action (every next continuous pressing will invert the
previous one).
This pushbutton is useful during the setting up of the plant.
Diagnostic of DALI line by yellow LED
The yellow LED, located near the just described pushbut-
ton, continuously flashes during normal operation. Since
the DALI line is continuously polled in a sequential way,
thus the LED flashes in the same way, even if DFCP con-
troller is not connected.
The yellow LED will be fixed lighted when one or more of
the following events will occur on the DALI line:
•
Lamp failure
•
DALI line broken or no ballast connected
•
Short circuit on DALI line
In the case of short circuit, an automatic procedure will try
to restore the line, thus allowing to module to return to to
the normal operation with a maximum 15 sec delay after
the short circuit condition has been removed.
The LED will be instead switched off if the DALI section of
the module is not supplied or if the polling has been dis-
abled. In any case, the occurred problem can be discrimin-
ated by the map of DCP IDE or BDTools or by a supervisor
or video-terminal connected to DFCP (reading input chan-
nel as described in the related paragraph).
Note:
✗
In lamp failure condition, it is not possible to know on which
DALI device this event occurred.
