Parameters for scenes

Luminaires or luminaire groups can optionally be integrated in up to 16 scenes, which means that pre-programmed static light scenes can be recalled by influencing the brightness, colour temperature or colour. If necessary, the scene values can be switched over and individually adapted and saved during operation of the device, allowing the user to replace the presettings of the ETS as desired. The extended scene recall allows scenes to be switched over by switching commands.

The scene function must be enabled by this parameter so that the required communication objects and parameters become available.

The extended scene recall allows up to 16 scenes of a DALI system to be called up in sequence. Here, scene recall takes place via the 1-bit communication object "Extended scene recall". Each ON telegram received via this object recalls the next of the available scenes in the configuration. Each OFF telegram received recalls the previous scene.

In the event of an extended scene recall, the gateway always recalls the neighbouring scene - starting with the scene most recently recalled by the extended recall. It is irrelevant whether the scene is active (scene number = "1...64" or scene active) or inactive (scene number = "0" or scene inactive). When an ineffective scene is recalled by the extended scene recall, the assigned group or single device does not react.

Only the scenes available in the scene configuration can be selected via the extended scene recall (with "variable" defined by the parameter "number of scenes", with "fixed" always all 16 scenes). After a reset (bus/mains voltage return, ETS programming operation), an ON or OFF telegram always recalls scene 1 first.

The extended scene recall can take place with or without an overflow at the scene limits. An overflow occurs when the last scene of the selected configuration is reached when counting up or scene 1 when counting down and an additional telegram is received in the last counting direction.

Each scene receives a unique number (1...16), which is shown in square brackets before the name in the view of the parameter pages. This number is only a label within the ETS in order to distinguish clearly between the individual scenes, even if they have the same name. In addition, scenes have KNX numbers (1...64). These KNX numbers can be used to recall a scene or a scene memory function using the scene extension object. Scene numbers do not have to be identical to KNX extension numbers. However, KNX numbers must be unique. It is not possible to assign the same KNX numbers to multiple scenes of a DALI system.

The scene configuration selected here decides whether the number of scenes is either variable (1 ... 16) or alternatively fixed to the maximum (16).

variable (1...16 scenes): In this setting, the number of scenes used can be selected anywhere within the range of 1 to 16. The "Number of scenes" parameter decides how many scenes are available in the ETS for the selected DALI system. It is possible to specify which scene number (1 ... 64) controls each scene. If necessary, individual scenes can be switched to inactive by configuring the scene number "0".

fixed (16 scenes): With this setting, all scenes are always visible and can therefore be used. The scenes are controlled via permanently assigned scene numbers (1 ... 16) (scene number 1 -> scene 1, scene number 2 -> scene 2 ...). If necessary, individual scenes can be deactivated.

This parameter decides how many scenes are available in the ETS for the selected DALI system.

This parameter is only available with variable scene configuration.

Each scene receives a unique number (1...16), which is shown in square brackets before the name in the view of the parameter pages. This number is only a label within the ETS in order to distinguish clearly between the individual scenes, even if they have the same name. In addition, scenes have KNX numbers (1...64). These KNX numbers can be used to recall a scene or a scene memory function using the scene extension object. Scene numbers do not have to be identical to KNX extension numbers. However, KNX numbers must be unique. It is not possible to assign the same KNX numbers to multiple scenes of a DALI system. If necessary, individual scenes can be switched to inactive by configuring the scene number "0".

The default setting of the parameter depends on the number of the selected scene.

This parameter is only available with variable scene configuration. With a fixed scene configuration, the scenes are controlled by permanently assigned scene numbers.

With a fixed scene configuration, individual scenes can be switched to inactive by this parameter if necessary.

This parameter is only available with fixed scene configuration.

Each scene can be given a designation, which is visible only in the ETS for better identification.

The priority of the scene function over the disabling or forced position functions of a group or single device can be configured for each scene. Thus, it is possible for a scene recall to override a disabling or forced position function. Alternatively, a scene can have a lower priority, which means that disabling functions or forced positions cannot be overridden by a scene recall.

Low: The scene is of lower priority to the supplementary functions of the assigned groups or single devices. It is not possible to call up or save a scene if a supplementary functions is activated only for one assigned group or single device.

High: The scene is of higher priority to the supplementary functions of the assigned groups or single devices. Scenes are only ever called-up or saved when a scene extension device is received. A scene recall does not statically lock the lower-level functions of a group or single device. The higher priority only determines that scene values are set at the moment the scene is recalled and override the previously active values. After a scene is recalled, it is possible for the scene values to be subsequently changed by other functions of the gateway (e.g. on terminating a supplementary function or by switching, dimming or preset value).

When storing a scene, the scene values are stored internally to a non-volatile memory in the device. To prevent the stored values from being replaced during ETS programming of the application or parameters by the originally programmed scene brightness values, the gateway can inhibit overwriting of the scene values. As an alternative, the original values can be reloaded into the device during each programming run of the ETS.

Parameter activated: During each ETS programming operation of the application program or of the parameters, the scene values configured in the ETS are programmed into the gateway. Scene values stored in the device by means of a storage function will be overwritten, if any.

Parameter deactivated: The scene values stored in the device by a storage function are maintained. If no scene values have been stored, the scene values last programmed in the ETS remain valid.

Each scene recall can optionally also be evaluated after a delay. With this feature, dynamical scene sequences can, for example, be configured if several actuators or gateways are combined with cyclical scene telegrams.

Parameter activated: The delay time is activated. The delay only influences the scene recall of the appropriate scene. The delay time is started on arrival of a recall telegram. Only after the time has elapsed is the corresponding scene called up and the scene values set.

Parameter deactivated: The delay time is deactivated. A scene recall is carried out without a delay immediately after the receipt of a scene recall telegram.

The delay time configured here is started when a recall telegram arrives. Only after the time has elapsed is the corresponding scene called up and the scene values set.

Each scene recall telegram restarts the delay time and retriggers it. If a new scene recall telegram is received while a delay is active (scene recall not yet executed), the old (and not yet recalled scene) will be rejected and only the scene last received executed.

This parameter is available only when the scene recall delay is active.

You can define here whether the scene values for the assigned groups or single devices are to be called up by being instantly jumped to or dimmed to. A scene recall can therefore be executed independently of the set dimming behaviour.

Jumping to values: The values of the scene concerned are jumped to instantly during a recall.

Dimming to values via fading: The values of the scene concerned are dimmed to during a recall. The dim fading is activated. The fading time defines the duration of the dimming process until the new values are achieved. The brightness, colour temperature and colour values of a group or single device at which the dimming process starts has no significance. The dimming process in the event of a scene recall always requires the exactly specified time for all groups and single devices of the scene.

Setting of the fading time for dimming to the scene values.

This parameter is available only for "On scene request = dimming values via fading".

This parameter defines the assignment of the group or single device to the scene. Only assigned groups and single devices are processed during a scene recall or when saving a scene. If this parameter is deactivated, no scene parameters can be set for the corresponding group or single device.

This parameter defines the assignment of the group or single device to the brightness control of the scene. If the checkbox is selected, the scene influences the brightness. If it is deleted, the brightness value of the group or single device remains unchanged when the scene is recalled.

During a scene recall, the appropriate configured brightness value is set on the operating devices.

The current brightness value can be saved in the gateway when a storage telegram is received via the scene extension object. When the checkbox is activated, the brightness storage function is activated for the group or single device concerned. The current brightness value is stored in the gateway in the scene via the extension object when a storage telegram is received.

This parameter defines the assignment of the group or single device to the colour temperature control of the scene. If the checkbox is selected, the scene influences the colour temperature. If it is deleted, the colour temperature value of the group or single device remains unchanged when the scene is recalled.

The "Colour temperature" category is available only for groups or single devices that enable this range of functions.

When a scene is recalled, the respective configured colour temperature value is set on the operating devices.

The current colour temperature value can be saved in the gateway when a storage telegram is received via the scene extension object. When the checkbox is activated, the colour temperature storage function is activated for the group or single device concerned. The current colour temperature value is stored in the gateway in the scene via the extension object when a storage telegram is received.

This parameter defines the assignment of the group or single device to the colour control of the scene. If the checkbox is selected, the scene influences the colour and optionally the white value. If it is deleted, the colour or the white value of the group or single device remains unchanged when the scene is recalled.

The "Colour" category is available only for groups or single devices that enable this range of functions.

When a scene is recalled, the respective configured RGB colour value is set on the operating devices.

For groups and single devices, a white value can also be defined in the scene in addition to the RGB colour value in the "Colour RGBW" scope of functions.

The current colour value can be saved in the gateway when a storage telegram is received via the scene extension object. When the checkbox is activated, the storage function for the colour and optionally also the white value is activated for the group or single device concerned. When a storage telegram is received via the extension object, the colour and the white value in the gateway are stored in the scene.
