Control of the DALI
devices
The following two solutions have been implemented in the 1-fold DALI-
Gateway DG/S 1.1 to control and monitor the 128 DALI devices due to the
limited number of 255 communication objects in the bus coupler.
1. Broadcast control of the main and auxiliary channel
All devices of a channel can be controlled or read in broadcast mode, i.e. all
devices can be read or controlled together. All the devices on the channel
are controlled and monitored with just one communication object “Channel x”
(x = A or B). This is the same method of function which has been tried and
tested with the ABB i-bus® EIB / KNX 8-fold DALI-Gateway DG/S 8.1.
•
Channel x – On/Off
•
Channel x – Relative Dimming
•
Channel x – Set Brightness Value
•
Channel x – Device Slave Mode
•
Channel x – Telegr. Fault DALI
•
Channel x – Telegr. Fault Lamp(s)
•
Channel x – Telegr. Fault Device
2. Individual control of a device
Each of the individual 64 DALI devices of main channel A can be switched
on/off, dimmed or the brightness can be adjusted with just one "Device Axy"
communication object, as is usually the case in the EIB / KNX.
•
Device Axy – Switch/Status
•
Device Axy – Relative Dimming
•
Device Axy – Brightness value/Status
In addition, the 1-fold DALI-Gateway DG/S 1.1 features an address-related
individual option to control or read every single device of main channel A as
well as auxiliary channel B.
First of all, the communication object
•
Channel x – Selected Device
will select a device via its device address.
With a second telegram to one of the following communication objects, each
of the 128 DALI devices can be individually controlled or read.
•
Channel x – Selected Device On/Off
•
Channel x – Selected Device Rel. Dimming
•
Channel x – Selected Device Set Value
•
Channel x – Selected Device Slave Mode
•
Channel x – Selected Device Burn in Lamps
•
Channel x – Selected Device Read Position
•
Channel x – Selected Device Read Brightn.
•
Channel x – Selected Device Lamp Failure
•
Channel x – Selected Device Device Failure
