2.1.1.6.2.7 Description of Extended Commands
0x01 Store Scene/Parameter (Set_Various_Level)
This macro allows the DALI storage algorithms to be processed according to
the following pattern: Load "Parameter 1" into DTR and store DTR as
"Parameter 2", repeat storage command. For example, 'Parameter 2' may be
'MAX LEVEL' or 'FADE TIME'.
0x02 New Addressing (Generate_Short_Address)
Automatic address allocation using the random electronic ballast long
addresses. Algorithm according to DIN 60929 E.4.3.4. The macro is awaiting
for a parameter 1 describing the type of initialisation (low byte of DALI
command 258).
- 0x00 all lamps will be initialized
- 0Adr1 lamps with address 'Adr' will be initialized
- 0xff lamps without short address will be initialized
All search addresses used in the algorithm are sent back on the return channel
(message 3 - 5). When a short address is allocated, the lamps assigned to this
address are lighting. When performing a system extension (Parameter 1 =
0xff), it is necessary to check if the short address has already been allocated
before assigning the short addresses by polling the slaves. Newly allocated
short addresses will be immediately transferred to the present register. The
macro stops when no long addresses can be found or when the slave address
exceeds number 63.
Parameter 2 contains information about the behaviour of addressed electronic
ballasts:
- Bit 0:
0 =electronic ballast is controlled brightly after the address
assignment
1 = electronic ballast remains unchanged after the address
assignment
- Bit
1...7
reserved
0x03 Delete Short Address (Delete_Short_Address)
Delete the short address (DALI addr.) of one single ballast or all ballasts
(DALI address = 0xFF, broadcast). The present registers will be updated.
