Table 1 contains a complete summary of the DALI command set. Basically there are four types of commands (forward frames):
1. Direct / Indirect arc power control commands – used to set ballast power level.
2. Configuration commands – configures the ballast (for example: add to a group or store level). Command must be repeated within 100 ms, otherwise it’s ignored.
3. Query commands – ask slave (ballast) for status information (for example: power level or version number). The slave can send a backward frame.
4. Special commands – used to initialize and setup the ballast, some must be repeated within 100 ms, and some require an answer from the slave. Most commands are only processed within 15 minutes after an “INITIALIZE” command is received.
