ADDICT v3.0.1 User Manual DALI Functionality

The following example shows a “query lamp failure” command sent to group 0, and 0.01s later
invalid data was detected on the line, indicating that more than one device in group 0 tried to
respond with YES (or FF) to the query. Therefore, at least two devices in that group have lamp
failures. See Error or Yes details below.
Most of the DALI commands that can be sent from a master to slave can have either a single
address, a group of devices or all devices as their target (as shown in the above example by the
different M→ commands). However, there are a set of “special” commands that are always
sent to all devices (although not all the devices may react to the command, depending on the
situation). When displaying a packet (with descriptive display mode selected) these are prefixed
with “SPEC.”
The following examples show a “store 128 in the DTR (Data Transfer Register)” command and an
“Initialise New Devices” (i.e. devices without addresses) command.
Newer DALI protocols define 3-byte e-DALI commands that can be sent between controllers on a
DALI line and will be ignored by slave devices. The ADDICT
®
can sniff these 3-byte commands
during sniffing, but will show only the raw hex values.
Selectable values:
• Packet number (1 – number of packets) – The packet data will be displayed as the packet
number is being selected
