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
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-
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.

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.
Output section
The related data field (16-bit) for the execution of the com­mands on the ballasts, has the following meaning:

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

(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).

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.

HOME AND BUILDING AUTOMATION
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.

Domino
DFDALI
Setting up
DFDALI module is shown into the map of DCP IDE or BDTools like in the following figure. As for all Domino mod­ules, the background of the module will be in green color if the module is connected and properly working, otherwise the background will be in red color.
The portion on the left side is related to the input section and it reports the diagnostic information and the brightness level of ballast 1 (text box on the bottom); if the option “Regulation status” has been checked in the configuration panel, then this text box reports the automatic regulation status of the 8 zones (in decimal format to be interpreted in binary mode). The portion on the right side is related to the output section and it features two text boxes for entering the destination and command values.
DCP IDE and BDTools allow to set the operating paramet­ers of the DALI line during the system setting up and to perform some diagnostic functions. DFDALI module can be adapted to any specific application. The setting up is per­formed via the Domino bus and DFCP (or DFRS or DFPRO) through a specific configuration panel that can be accessed from the menu of DCP IDE or BDTools.
From the menu, select Programming, Modules Configura­tion and then DFDALI. The window shown in Figure 2 will be opened; the main parameters and options can be here defined as it will be described in the following of this para­graph.
Before to proceed with any action, the communication between the PC and, for instance, DFCP has to be opened. The top side of the configuration panel reports the section for the addresses management.
After having entered the address of the DFDALI to be man­aged, it is possible to enable the input address of the mod­ule through the check box named “Input Address” and then clicking on the button Program; by the button Read it is in­stead possible to check the current setting.
It is also possible to activate the “Regulation Status” inform­ation related to the 8 zones by checking the related option and then pressing the button Program. This option, of course, requires that the input section have been enabled.
Six tabs in the window allow some well defined functions as described in the following.
The button ID & Ver. on the lower side allows to read the firmware version of the selected DFDALI module.

Addressing
3 mutually exclusive functions are available: Set address. In the first case, an address will be assigned
to all the connected ballasts, and the starting address can be chosen (the typical value is 1).
This type of addressing assigns consecutive values, in the range 1 to 32, to the ballasts in a random order.
If some ballasts on the line have been previously ad­dressed and some other ballasts have to be added, the ad­dressing procedure can be performed without any modifica­tion to the previously assigned addresses. Mainly in this case, a starting address other than 1 can be useful. A timer icon will inform that the operation is running.
At the end of the procedure, the normal mouse icon will be restored. The time required for this procedure is about:
T = 5sec + (6sec x “nr. of ballasts”)
Remove the address. If some addressing or reconfiguration errors occurred, it can be useful removing the address of all the ballasts on the line or of a well specified ballast.
Restore the factory setting. The DALI ballasts are factory set without any address and with a basic configuration for the main parameters; the following table shows a typical default configuration:
Parameter Value
Minimum brightness level 1% Maximum brightness level 100% Brightness level in failure condi-
tions Ramp value 0 seconds Preset None
100%
Domino
DFDALI
These settings can be restored both for all ballasts connec­ted to the line and for a single ballast.
Restoring of the settings does not imply the reset of the ballast address. The visible result of the factory setting restoring is the switching on of the lamps at the bus failure default level, that is typically 100%.
Mapping
Once the ballasts have been random addressed, it can be useful to reorder the assigned addresses, thus simplifying the supervision and the management of ballasts, Figure 3.
The address 1 to 32 of each ballast can be changed to a new desired value (always in the range 1 to 32). For each address, the program shows a line similar to the following
one: .
The button 0 allows to switch off the ballast with address specified in the gray text box (1 in this example) while the button I allows the switching on; this function is useful to see where the ballast addressed 1 (in this example) is physically located. In the white text box the new desired ad­dress must be entered (23 in this example) for the ballast whose current address is 1.
The execution of the mapping procedure (pressing the but­ton Start) will take place only for the ballasts selected by the related checkbox. A timer icon will inform that the oper­ation is running. At the end of the procedure, the normal mouse icon will be restored. The time require by the map­ping procedure is about 1sec per ballast.
If the procedure has not been successfully executed, a win­dow reporting “Error during mapping” will appear.

In this case, follows these steps:
click on the button “Recover” to remove the address of
each ballast for which the mapping procedure has not been successfully completed
address again the ballasts without address selecting
as starting address a free value followed by a suffi­cient number of free addresses (see the Status TAB)
execute again the mapping procedure
The correctness of the changes made can be checked by switching on and off the ballasts using the buttons identified as 0 (off) and I (on).
The two big buttons 0 and I on the left side allow to switch off and to switch on all the ballasts connected to the line.
The buttons Select (select all) and Deselect (deselect all) and Reset (restore the address value in the consecutive or­der) complete this TAB.
Domino
DFDALI
The button Deselect remove all the X symbols on the grid. The execution of the assignment of the groups (clicking on
the button Start) will take in account only the ballast selec­ted by the X symbol. A timer icon will inform that the opera­tion is running. At the end of the procedure, the normal mouse icon will be restored.
If the procedure has not been successfully executed, the warning in following window will be shown:
In this case the procedure has to be repeated.
Groups This TAB, Figure 4, features a grid where each ballast can
be assigned to one or more groups. This choice can be done by clicking on each cell located at the intersection between the desired ballast (the columns) and the desired group (the rows).A X symbol will be shown in the related cell.
In the example of the figure here on the right side, the group 1 contains the ballasts 1-2-5, the group 2 the bal­lasts 1-3 and the group 3 the ballasts 2-4-5.
The correctness of the changes made can be checked by switching on and off the ballasts using the buttons identified as 0 (off) and I (on); the buttons on the top side act on the single ballast, the buttons on the left side act on the groups and the two big buttons 0 and I switch off and on all the bal­last on the line.
The buttons From File and To File allow to store and recall the settings of the groups; take in account that it is not pos­sible to read, from DFDALI module, the current settings of the groups, therefore it is strongly recommended to save them into a file for future modifications.
The time required by this procedure is about:
T = 8sec + (0,5sec x “nr. of X in the window”)

Enter the desired parameters and then click on Start to send the configuration. The time required by this procedure is about 15 seconds.
If the procedure has not been successfully executed, a warning window will be shown; in this case the procedure has to be repeated.
Status
This TAB, Figure 6, shows, if the ballasts have been ad­dressed, the current brightness level of each ballast. These values are in the range 1 to 100; when a ballast does not answer to the polling, the reported value will be 255 (and the table will show “-”).
If a lamp failure occurs, a X symbol on a pink background will be shown.
In addition it is possible to force the brightness entering the value in the cell related to the desired device and confirm­ing by the Enter key.
A pair of buttons on the top side of the table allow to enable and disable the polling on the DALI line. When the polling is disabled, the label “Base address” will be shown over a red background.
The buttons “Snapshot to File” and “Restore from File” al­low respectively to save and recall a given configuration of brightness levels; in this way it is possible to save on the PC one or more sceneries (each scenery will be a file).
I/V Table
The TAB shown in Figure 7 allows to create up to 58 rela­tionship between real or virtual inputs of the Domino bus and the following commands: Up, Down, Single Command, Save scenery and Recall scenery. For each command simply enter the input point (without I or V, with ! if negation is required), the function and the channel or the scenery.

These functions are managed directly by DFDALI module, thus without the need of any controller and any program­ming. To compile the table, left click with the mouse on the first available cell on the Input column, enter address and point (without I or V, with ! if needed) and press Enter. The command list will appear: choose the desired function among Mono, Up, Down, Recall, Save; the other two op­tions are related to the automatic bright­ness regulation, see next paragraph. The cell of the column Cmd will then show the symbol of the chosen function; to change the function, simply click again on the cell. Select the desired function; the cell of the column Cmd will then show the symbol of the chosen function (U, D, M, R, S); to change the function, simply click again on the cell. The next cell on the column B/G (Broadcast or Group) will be then automatically highlighted: enter the desired value, that is 0 for Broadcast or the desired group number number 1 to 15 (note: group 16 cannot be used in the I/V table) and press Enter. If instead the desired function is Save or Re­call scenery, press Enter again: the related cell will be auto­matically highlighted in the column S (Scenery): enter the desire number, that is the number of the scenery (1 to 16) to be saved or recalled, then press Enter. The buttons Start Prog. and Start Read. in the I/V Table TAB allow, respectively, to transfer the values currently shown in the I/V Table to DFDALI module and read the cur­rent configuration of DFDALI and report it into the table.
The buttons From File and To File allow, respectively, to open a file, with .TIV extension, containing a previously saved I/V table and to save the I/V table shown in the win­dow to a file. The Default button clears the table.

Automatic brightness regulation
DFDALI module, starting from firmware version2.0, imple­ments the automatic brightness regulation as function of a light sensor connected to the Domino bus (e.g. DFLUX). The TAB shown in Figure 8 allow to manage up to 8 zones (each one corresponding to a group in the range 1 to 8).
These functions are managed directly by DFDALI module, therefore no controller or specific programming is required.
To fill the table, double left click in the cell related to the zone to be set in the Sensor Address column, enter the ad­dress of the light sensor (e.g. DFLUX module) for that zone and press Enter. The cell related to Setpoint will be then automatically highlighted: enter the desired value and press Enter. The sequence is the same also for the next paramet­ers: Hysteresis, T. Regulation, K and Start Value.
Setpoint is the brightness level that has to be kept. The regulation function works in order to keep the light value read from the sensor in the range (setpoint - hysteresis) to (setpoint + hysteresis).
The regulation time, in seconds, is the interval with which the module compares the light level read by the sensor to the setpoint.
K is a parameter which, multiplied by the error (defined as the difference between the setpoint and the brightness value measured by the sensor), defines the magnitude of the increase or the decrease, in respect to the previous value, to be sent to the ballasts. In practice, larger values of K increase the speed of the approaching to the set point.

Small values of K allow for greater stability of the regulation but a slower response, while large values of K make the re­sponse faster, but some oscillations can appear.
Start Value is the value from which the regulation starts when it is activated.
The Auto options, when checked, place that zone in auto­matic regulation mode at the power up of the ballasts or of the Domino bus; if the option is not checked, the lights will go to the value set in the ballasts (typically 100 %).
Figure 8 shows some typical value for the just described parameters.
The buttons Start Prog. and Start Read. allow, respectively, to transfer the values currently shown in the table to DF­DALI module and read the current configuration of DFDALI and report it into the table.
The buttons From File and To File allow, respectively, to open a file, with .TRG extension, containing a previously saved regulation table and to save the table shown in the window to a file. The Default button clears the table.
To change the setpoint value of a group from a supervisor
or similar devices, the destinations 0x91 ÷ 0x98 have to be
used, as described in “Commands via bus” paragraph.
The functions 0xDD, 0xDE 0xDF allow to enable and dis­able the automatic regulation from the bus on the group
specified by the Destination field (0x81 ÷ 0x88)
