2.4.1 Single DALI device signals
There are up to 94 signals for each DALI device or ballast. Their Modbus addresses can be obtained applying the following formula:
Modbus Address = 7000 x C (100 x BALLAST) + SIGNAL NUMBER
Where:
CHANNEL NUMBER;
0..1 (always 0 if using version with support for 1 DALI channel)
BALLAST NUMBER:
0..63 (ballast short address)
SIGNAL NUMBER:
0..93, 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)
