DFDALI
The value of the current brightness level is in the range 0 to
100; if no ballast has been addressed as 1, then the repor-
ted value will be 255. A lamp failure condition will be in-
stead reported by the value 128; if the answer from the bal-
last will not be understood the value 129 will be reported.
If the brightness level of each ballast on the DALI line is re-
quired 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 auto-
matic brightness regulation of the relevant zone. For in-
stance, 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 com-
mands on the ballasts, has the following meaning:

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:

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 de-
scribed 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).

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 cur-
rent level). The code 113 will enable again the polling; the cur-
rent 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.
