ABB DG/S 1.1

Configuration

The ABB DG/S 1.1 supports two DALI channels, A and B. For each channel, one definition has to be added within the ABB DG/S 1.1 definition table. If you are using both channels of a single gateway, you have to distinguish them only by the name. For example, you can use "My DALI Gateway - Channel A" and "My DALI Gateway - Channel B" as names for the two definitions.

In addition to the common configuration options the following configuration options are available for each channel:

parameter	type	optional/mandatory	communication object	description	default
Fault Dali	ItemId	O	KNX Object #4 or #22, polled	True, if there is a general DALI error.
Fault Lamps	ItemId	M	KNX Object #5 or #23, polled	True, if there is a lamp error for at least 1 DALI device.
Fault Device	ItemId	M	KNX Object #6 or #24, polled	True, if there is a ballast failure for at least 1 DALI device.
Select Device	ItemId	M	KNX Object #7 or #25
Selected Device OnOff	ItemId	O	KNX Object #8 or #26
Selected Device Lamp Failure	ItemId	M	KNX Object #15 or #33
Selected Device Device Failure	ItemId	M	KNX Object #16 or #34
Change of device sends faults	bool	O		If true, the gateway automatically sends fault information when a new device is selected.	false
Change of device sends status	bool	O		If true, the gateway automatically sends status information when a new device is selected.	false

Functional description

The ABB DG/S 1.1 does not support emergency lighting. However, it provides the possibility to monitor lamp and device fault of all connected DALI devices.

Fault information is provided by three Server Items which are located directly under the gateway branch within the Server Item Tree:

item name	description
KNX IP Connection	This item reflects the KNXnet/IP tunneling connection to KNXnet/IP router or interface which is used to communicate with the KNX/DALI gateway.
Fault	True, if there is either a Dali, Ballast or Lamp fault.
Fault DALI	True, if there is a fault of the DALI communication of the channel.
Fault Devices	True, if there is a fault on one or more DALI devices on the channel.
Fault Lamp	True, if there is a lamp fault of one or more DALI devices on the channel. In case of a fault, LaMPS starts to test all configured devices in order to see which device(s) have a fault.
Fault Ballast	True, if there is a ballast fault of one or more DALI devices on the channel. In case of a fault, LaMPS starts to test all configured devices in order to see which device(s) have a fault.

Normal DALI testing server items per DALI gateway

item name	access	description
Trigger faulty devices only	RW	If true then the next test will test only devices that are mentioned in the Faulty devices server item. Otherwise all devices are tested.
Trigger Test	W	Used to trigger a normal DALI test for all devices.
Test Running	R	True, when a normal DALI test is currently running.
Number Faulty Devices	R	Number of faulty devices as determined in the last test execution.
Faulty devices	R	A comma-separated sorted list of numbers of faulty DALI devices.

Testing is done by used the KNX communication selected device. First, LaMPS sets the DALI number of the device under test to the communication "Select Device". Then the KNX communication objects "Selected Device Lamp Failure" and "Selected Device Device Failure" are evaluated. If the DALI gateway sends the fault information automatically ("Change of device sends faults" is configured to "F"), LaMPS waits for the KNX telegram. If the gateway does not push the information, LaMPS sends a read request.

For each configured DALI device, a sub-tree named "Device<number>" is shown within the Server Item Tree. Each device has the following Server Items:

item name	description
Name	Human-readable name of the DALI device. The default name is "Device<number>". This name can be changed within the Device Name Mapping Definitions.
Fault	True, if either a lamp or a device fault occurred.
Fault Lamp	True, if a lamp fault occurred.
Fault Ballast	True, if a ballast fault occurred.
OnOff	This item provides the current OnOff status and can be used to control the DALI device. LaMPS uses the KNX communication objects "Select Device" and "Selected Device OnOff" to provide this functionality.
