5.2 C-Bus Setup
Program the C-Bus DALI Gateway using C-Bus Toolkit software that can be
downloaded free of charge from the Internet.
To determine the C-Bus group addresses, refer to the DALI programming table.
Since these are effectively fixed, we suggest that the DALI Gateway and any key
input units associated with DALI be placed on another lighting application, such
as $39 (57) to avoid unforseen interactions between DALI and any existing C-Bus
lighting project.
6.0 Scenes
The DALI system provides for scenes by pre-programming each unit to be ‘aware’
of which scenes it participates in and setting a specified arc level for that scene.
Sending the DALI_1_SCENE12, for example, will notify all units in that scene to
carry out their programmed action.
The DALI scenes are quite independent of the groups and the units do not betray
their membership in a scene in any remotely assessable way. The DALI scene
message does not describe which units are involved, so ‘listening in’ on the DALI
network traffic would not provide information about which loads are involved.
A C-Bus scene, on the other hand, includes both the scene triggering message
(on the trigger control application) and the subsequent lighting messages (on the
lighting application), so the relevant parts of the state of the system can be inferred
from the messages.
In addition to this, C-Bus scenes can be actioned by numerous devices, such as
Scene Master, Neo, Reflections, C-Touch, and software such as C-Gate. Any C-Bus
input device anywhere on the network can trigger these devices and software.
In general, we recommend that scenes be implemented using C-Bus: the DALI
network will participate in any scenes generated by C-Bus via the DALI Gateway.
All monitoring software will be appraised of scene progress through the usual C-Bus
techniques. Individual DALI keys can still be used provided they are programmed
to address groups only. Any application address from $30 (48) to $5F (95) is a valid
lighting address.
As mentioned above, scenes can be implemented using DALI, but unfortunately any
monitoring package is ‘blind’ to what is going on over the network.
