DFDALI: DALI gateway
DFDALI module allows to manage up to 32 DALI ballasts
(or similar devices) through the Domino bus.
DFDALI module can be successfully employed in domestic
and professional lighting applications, where systems communicating by the DALI protocol are used.
DFDALI module offers the following main features:
✗ all timing functions are accomplished by the module
and it may be controlled by any real or virtual input of
the system, by supervisor or by video terminal
✗ it can operate without DFCP controller
✗ possibility of control from one or more pushbuttons con-
nected to Domino bus
✗ Up/Down and Single commands may be defined for the
manual regulation of lighting level
✗ automatic brightness regulation (also without DFCP)
✗ programmable ramp, in the range 0 to 60 seconds
✗ setting of minimum and maximum output levels
✗ dynamic lights scenes can be easily implemented
through DFCP
✗ the current brightness level may be stored and then re-
called; up to 16 presets are available to create “real
time” lighting scenes; the preset will be stored in the
non-volatile memory of the ballasts
✗ if a Domino or DALI bus failure occurs, the output level
will be automatically set to a user-defined level
✗ diagnostics of short circuit on the DALI line and lamp
failure
✗ galvanic insulation between DALI and Domino buses
Domino
DFDALI
Near to the Domino bus terminal block, the module features a small pushbutton for the assignment of the address
and a green LED that shows the operating status; this
green LED normally flashes every 2 seconds about to signal that the module is properly supplied and operating.
Near to the DALI bus terminal block, the module features a
small pushbutton for the manual command of the connected devices; the function performed by this button are the
continuous regulation of the brightness level and the onetouch switching on and off. Near to this button, a yellow
LED reports the communication activity on the DALI line or
the diagnostic.
Removing the cover of the bus terminal block, a small connector (PRG) can be accessed; this one allows the connection to DFPRO optional tester/programmer.
DFDALI module is housed in a standard DIN 4M box for rail
mounting.
The 32 devices for each line can be controlled as follows:
Broadcast: each command sent on the DALI line will be ex-
ecuted by all the connected devices, therefore all the related devices will behave in the same way.
Individually: the commands will be individually sent to each
device, therefore each single device will behave independently; for this operation, the DALI devices must be addressed as described in the following paragraphs.
Groups: the command will be sent to groups, therefore
each group of devices will behave independently; for this
operation, DALI devices must be addressed and the groups
must be defined as described in the following paragraphs.
DFDALI module can operate in systems with or without
DFCP controller. In all cases, the module can perform Up,
Down and Single Command functions by real or virtual inputs (see in the following of this manual); moreover, saving
and recalling of sceneries can be accomplished by the
module.
The power supply needed for DFDALI module operation is
derived from the Domino bus itself and from an auxiliary
power supply for the DALI section.
Three fixed 2-way terminal block allow the connection of
the module to the Domino bus, to the auxiliary power supply and to the DALI bus.
Note: this technical sheet applies to DFDALI modules
equipped with firmware 2.2 or higher.
Address programming
DFDALI module takes one output address and, if enabled,
one input address. A white label on the front panel allows
the writing of the assigned address for an immediate visual
identification. For details about address programming refer
to the related documentation.
Wiring diagram
The schematic diagram in Figure 1 shows the connections
to be made between DFDALI module and the Domino bus,
the auxiliary power supply and the DALI line, using cables
as described in the table in the following of this same paragraph. As said above, DFDALI module performs galvanic
insulation between DALI section and Domino bus by
means of photo couplers inside the module.
The auxiliary power supply (AUX SUPPLY in the schematic) can be a transformer with 12V~ secondary winding (at
full load) 3VA, or it can be a stabilized dc power supply 12V
± 5% / 0.25A; in this last case the polarity is automatic,
so the positive pole can be connected indifferently to the
terminal 19 or 20.

It is suggested to use, for the DALI line, a normal 2-core
cable with double insulation. It's allowed to lay these cables
in the same pipe in which there are power cables, provided
that they have double isolation too.

Input section
On the input address, if enabled, 16 bits are available for
the diagnostics of DALI system, as described in the following table:
It is recommended to avoid the using of multi core cables
carrying both the two DALI signals and ballast supply, because the capacitive coupling between the signal wires and
the power lines may cause very dangerous conditions for
the human safety.
The following table gives some rules for the MINIMUM
cable section. As said above, no special cables are required for the DALI line, provided that they have double insulation. In any case, the distance between DFDALI module and the farthest ballast must not be more than 300m.

Regulation Status of the 8 zones
The first available information (points 1÷8 of the channel)
can be chosen by the option “Regulation Status” in the configuration panel featured by DCP IDE or BDTools; the two
possibilities are:
Case 1(unchecked option):
the brightness level of the ballast having address 1 which is
assumed as reference for all the other ballasts. Thus, to
use this function, the ballasts have to be addressed starting
from address 1.

The value of the current brightness level is in the range 0 to
100; if no ballast has been addressed as 1, then the reported value will be 255. A lamp failure condition will be instead reported by the value 128; if the answer from the ballast will not be understood the value 129 will be reported.
If the brightness level of each ballast on the DALI line is required by the application, a script for DFCP is available for
this purpose; contact DUEMMEGI for more information.
Case 2 (checked option):
In this case, each point 1¸8 reports the status of the automatic brightness regulation of the relevant zone. For instance, point 1, when activated, reports that the automatic
brightness regulation is currently activated for zone 1.

Function
Destination
The destination can assume different values depending on
the typology of the addressed target, identified by the value
of the high byte of the channel, as in the following table:
Written data
HEX DEC
0x00 0 All the ballasts on the line
(broadcast)
0x01 ÷ 0x20 1 ÷ 32 single ballast (1÷32)
0x81 ÷ 0x90 129 ÷ 144 single group (1÷16) of ballasts
0x91 ÷ 0x98 145 ÷ 152
Set the setpoint value for the
automatic brightness regulation
for zones 1 ÷ 8
Destination
When the destination is broadcast or single ballast or single
group, the function executed by the module depends on the
value written on the low byte of the output data field, as described in the next table.
If instead the destination is in the range 0x91 to 0x98, then
the value specified by the low byte (Function) assumes the
meaning of “setpoint value” divided by 10 used for the
automatic brightness regulation; for instance, to send 300
as setpoint value on group 3, the value 0x931E has to be
sebt (0x93 means the setpoint setting for group 3 and 0x1E
= 30 is the wanted setpoint value: 30 x 10 = 300).

Disable the automatic brightness regulation and switch OFF
the lamps (the destination must

Disable the automatic bright-
ness regulation (the destination
must be a group in the range 1

The value to be written in the output data field to perform a
given function to a given destination will be thus:
✗ in hexadecimal: 0xYYZZ where YY is the destination in
hexadecimal format (HEX) and ZZ is the code of the
function in hexadecimal format (HEX)
✗ in decimal: K where K is given by [(256 x YY) + ZZ],
where YY is the destination in decimal format (DEC)
and ZZ is the code of the function in decimal format
(DEC)
Notes:
✗ DFDALI module, normally, polls all the ballasts connected to
the line; this polling can be disabled sending the code 112 (of
course losing all information about the diagnostic and the current level). The code 113 will enable again the polling; the current status of the polling is reported by the point 11 of the input
section (if enabled). At the module power up or after a reset
the polling is always enabled by default.

✗ 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.

DFDALI
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 releasing of the buttons).
Of course the commands to DALI devices can be also sent
by DFCP through the using of the Scripts.
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 installed DFDALI modules.
As option, or in addition, it is possible to send commands or
value from DFCP to the DALI module through proper equations 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 transferred 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 releasing of the buttons).
A similar example follows to send command to a group of
ballasts:
DFDALI module can however work without DFCP controller, 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 complete switching ON and OFF, while holding down the button
the brightness increases or decreases depending on previous 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 pushbutton, 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 controller 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 disabled. In any case, the occurred problem can be discriminated by the map of DCP IDE or BDTools or by a supervisor
or video-terminal connected to DFCP (reading input channel as described in the related paragraph).
Note:
✗ In lamp failure condition, it is not possible to know on which
DALI device this event occurred.
