DALI groups’ signals
DALI supports group addressing of ballasts. Up to 16 groups can be defined in a DALI channel. In Intesis, there are up to 16 signals for each DALI group. Their Modbus
addresses can be obtained applying the following formula:
Modbus Address = 7000 x c (20 x GROUP) + SIGNAL NUMBER
Where:
LINE NUMBER;
0..1 (always 0 if using version with support for 1 DALI channel)
GROUP NUMBER:
0..15 (ballast group)
SIGNAL NUMBER:
6400..6415, see following table
Modbus address from the formula is expressed in link layer format. This is, first register address is 0.
Supported signals vary according to device type. Following abbreviations are done in the table:
•
FL: Fluorescent light (device type 0)
•
EML: Emergency light (device type 1)
•
LED: LED module (device type 6)
