Assign DALI sensors

In the list of DALI sensors found, the instances available in the sensor and supported by the DALI Gateway are listed below each sensor found. These instances must be assigned to the sensor functions so that the DALI Gateway can understand the evaluation of the sensor signals. The following sections document the individual actions to be taken to create a sensor assignment in the DALI commissioning environment.

The sensors are allocated by assigning the instances of the sensors found listed in the right-hand display area to the left-hand display area.
To create an assignment, the instance types must be identical.
The assignment occurs as follows:

Select the instance of the DALI sensors found that is to be assigned.
Also select the sensor function of the configured DALI sensor of the same type as the selected instance.
Press the buttons between the two display areas.
Alternatively, an assignment is also possible with the help of the mouse by "drag and drop".

The DALI sensor found is now assigned to the configured DALI sensor channel. This assignment can be cancelled again by selecting an assigned instance in the left-hand display area and using the button to cancel the assignment.
The assignments of the instances can only be cancelled individually. It is not possible to select multiple instances.

The number of configured sensor channels can be set in the ETS parameter dialogue. If the number of sensor channels is reduced after sensor commissioning in the project design, the assignments to DALI sensors may become invalid. The next time the DCA is called up (via the "DCA" tab), the DCA identifies this status, removes the assignment of the affected devices in the commissioning dialogue and then requests a new sensor commissioning.

Example of configured DALI sensors in the left display area

(O)	DALI sensors found with existing instances
(W)	Configured DALI sensor channels from the parameter configuration incl. names
(X)	Automatically assigned sensor channels from the parameter configuration
(Y)	Sensor type and DALI instance type from the parameter configuration
(Z)	Status of the sensor assignments

When assigning the instances of DALI sensors found to configured sensor instances, the DCA always automatically checks the DALI sensor type. The instance type transmitted by the sensors is compared with the configured instance type. The DCA only creates an assignment if the instance types are the same (e.g. configured instance type = "1 (button)" -> compatible instance type of the sensor found must also be "1 (button)"). This prevents functional errors after commissioning.

Instance type	Description and standard reference	Note
0	Generic input IEC 60386-103	Instance type defined by the manufacturer
1	Push-button sensor IEC 60386-301	Standard DALI-2 instance type
2	Value transmitter absolute input devices IEC 60386-302	Standard DALI-2 instance type
3	Presence detector IEC 60386-303	Standard DALI-2 instance type
4	Light sensor IEC 60386-304	Standard DALI-2 instance type

ETS programming

ETS programming is required to complete sensor commissioning. This programs all sensor information into the DALI Gateway so that the DALI sensors can be accessed via KNX group addresses.
