Test "Groups (KNX)"
As soon as a DALI commissioning has been carried out and the application program has then been programmed with the ETS, the "Groups (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 a group.
In the DALI test of the groups, operating devices of a group 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 groups and 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 group is switched on. The gateway also generates status telegrams in the KNX system and includes the corresponding DALI group parameters (e.g. dimming behaviour and dimming characteristics).
The DALI group to be tested must first be selected in the "Select group" selection field. Here, only those groups - identified by the group names - are available for selection to which operating devices were also assigned in the course of a DALI commissioning. Only one group is testable at a time.
In the DALI test of the groups, each group can be switched on or off independently. Pressing the buttons "On" or "Off" causes immediate switching of the operating devices assigned to the appropriate group.
Alternatively, an absolute brightness value can be specified, which is transmitted to the group by pressing the "Set" button. The brightness value that can be set in the test environment is not dependent on the group parameterisation for minimum or maximum brightness. The full brightness range can therefore be set in the group-oriented DALI test. However, the operating devices of the group observe the parameterisation of the groups and react 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 group can be polled by pressing the "Read" button. The read group value is displayed in the selection field. Due to rounding, the displayed value may deviate from that most recently specified.
When testing a group from the "Brightness & Colour Temperature (DT8)" function range, pressing the "Set" button in the "Colour Temperature" area transmits the colour temperature value selected in the selection field to the corresponding group. The devices in the group should then immediately adjust to the specified colour temperature, but only if the lamps are 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 group-oriented DALI test. Similarly, the currently set colour temperature value of the group can be requested by pressing the "Read" button. The read group value is displayed in the selection field.
If the group to be tested is "Brightness & Colour RGB (DT8)" or "Brightness & Colour RGBW (DT8)", a test of the colour setting can be performed. When the "Set" button in the "Colour" area is pressed, the colour value selected in the selection field is transmitted to the corresponding group. If the group corresponds to the colour space "RGBW", the white value is testable in addition to the colour. When setting a value, the group immediately adjusts to the given colour, but only if the lamp is also switched on. Similarly, the currently set colour/white value of the group 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.
