DG/S 1.1, DALI-Gateway
ABB STOTZ KONTAKT GmbH has two EIB/DALI-Gateways in the ABB i-
bus® range, in order to integrate equipment with DALI interfaces into an
EIB / KNX building installation. Every gateway has its advantages which
benefit different project types. These differences are highlighted in the
following section.
The 1-fold DALI-Gateway DG/S 1.1 provides the possibility of addressing
two groups of 64 DALI devices individually and making them available on the
EIB / KNX. Two outputs (main and auxiliary channel) are available for this
purpose. The DALI wiring is implemented per output for each of the 64 DALI
devices using one core pair. A minimum cable length is thereby assured.
The use of individual addressing offers the maximum level of flexibility if
there is a redesign or change in the usage of a room or building.
During an initialisation phase automatically implemented by the gateway, all
of the DALI slaves are addressed and assigned to the EIB / KNX
communication objects in an ascending and non-arranged sequence. The
DGS11 Software Tool is available for individual manual readdressing and
testing of the DALI slaves.
Each of the individual 64 DALI devices can be connected to the main
channel A and can be directly switched, dimmed or controlled with a
brightness value using just one EIB / KNX communication object
The group assignment is implemented with the EIB / KNX group functions
via ETS.
DALI has a relative slow transfer rate of 1200 Baud, therfore it
is possible that EIB / KNX groups with more than 7 DALI
samples switched or dim not at the same time. The reason is
that one EIB/KNX telegramm released up to 64 single DALI
telegramms.
This behaviour is irrelevant for the broadcast mode.
The scanning of the individual lamp or ballast fault, as well as the activation
of a burn-in time or slave operation for every device, is implemented using
coded address-based control with two communication objects.
A further 64 DALI devices on a second auxiliary channel can be individually
controlled in broadcast mode. Each device of the auxiliary channel can also
be individually controlled with external logic or visualisation via coded
address-based control using two communication objects.
Every channel can also be controlled and monitored in broadcast mode, i.e.
all devices together.
If individual addressing is required, every individual device must be switched
on and the assignment determined during the commissioning and test
phase. The person carrying out the commissioning must be able to see the
operation of the lamps for this purpose. If necessary, the assignment must
be modified by readdressing the devices. The test phase can be
implemented with the DGS11 Software Tool (see appendix)
These circumstances indicate the project types for which the 1-fold DALI-
Gateway is particularly suitable. They are projects with so-called
multipurpose areas. They can be exhibition halls, museums, event centres,
sports arenas, open-plan offices or similar areas and rooms. All these
projects usually require that most of the lighting is switched on directly from
a single location. It is not possible in this case to forego the test phase but it
can be quickly implemented from a single location without the need for radio
or the requirement to walk through the entire building.
