Test "Single Devices (KNX)"
As soon as a DALI commissioning has been carried out and the application program has then been programmed with the ETS, the "single devices (KNX)" test can be carried out in the test environment of the DCA. During DALI commissioning, operating devices must have been found and at least one of them must have been assigned to an single device.
In the DALI test of the single devices, assigned operating devices - as in the test of groups - react with regard to switching and with regard to brightness, colour temperature and colour specifications as provided for by the parameterisation in the ETS. All the actions are implemented internally using the appropriate KNX objects of the single devices. Thus, the internal object values can be read out, for example, when the brightness values are read out and the switching object described internally when a single device is switched on. The gateway also generates status telegrams in the KNX system and includes the corresponding DALI single device parameters (e.g. dimming behaviour and dimming characteristics).
The single device to be tested must first be selected in the "Select single device" selection field. Here, only the single devices - identified by the single device names - to which operating devices were also assigned in the course of a DALI commissioning are available for selection. Only one single device can be tested at a time.
In the DALI test of the single devices, each device can be switched on or off independently. Pressing the "On" or "Off" button immediately causes the operating device assigned to the corresponding single device to be switched.
Alternatively, an absolute brightness value can be specified, which is transmitted to the single device by pressing the "Set" button. The brightness value that can be set in the test environment is not dependent on the single device parameterisation for minimum or maximum brightness. The full brightness range can therefore be set in the single-device-oriented DALI test. However, the single device observes the parameterisation and reacts accordingly in a restricted manner. This allows the parameter configuration and all KNX status messages to be checked without directly triggering KNX telegrams in the installation on input objects.
Similarly, the currently set brightness value of the single device can be polled by pressing the "Read" button. The read-out value is displayed in the selection box. Due to rounding, the displayed value may deviate from that most recently specified.
When testing an single device of the device type "DT8 (colour temperature)", pressing the "Set" button in the "Colour temperature" area transmits the colour temperature value selected in the selection field to the assigned operating device. The device should then adjust itself immediately to the specified colour temperature, but only if the lamp is also switched on. The colour temperature value is also independent of a configuration for the minimum or maximum colour temperature. So here, too, the entire colour temperature range can be set in the single-device-oriented DALI test. Similarly, the currently set colour temperature value of the single device can be requested by pressing the "Read" button. The read-out value is displayed in the selection box.
If the single device to be tested is of the device type "DT8 (colour RGB)" or "DT8 (colour RGBW)", a test of the colour setting can be carried out. When the "Set" button in the "Colour" area is pressed, the colour value selected in the selection field is transmitted to the corresponding single device. If the single device corresponds to the "RGBW" colour space, the white value can be tested in addition to the colour. When a value is set, the single device immediately adjusts to the specified colour, but only if the lamp is also switched on. Similarly, the currently set colour/white value of the single device can be requested by pressing the "Read" button. The read value is displayed in the selection field or in the slider of the white value.
