The first available information (the 8 lower bits of the chan-
nel) is the brightness level of the ballast having address 1
on each DALI line (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 val-
ue 128; if the answer from the ballast will not be under-
stood the value 129 will be reported.
If the brightness level of each ballast on each DALI line is
required by the application, a script for MCP is available for
this purpose; contact
DUEMMEGI
for more information.
Output section
4 channels 16 bit are available on the output address for
the execution of commands to the ballasts, as described in
the following table:
