Global switching status / Standby switch-off

The gateway is able to perform a standby switch-off of the connected DALI operating devices to save electrical energy when the lighting is switched off. Alternatively, the gateway provides a function for global reporting of the switching status of all projected groups and single devices.

The standby switch-off or the global switching status is a function across groups and single devices within a DALI system and is set on the parameter page "DALI system... -> General" if required. The "Global status" parameter defines whether the function is used as a standby switch-off or as a switching status. Depending on this setting, further parameters and a 1-bit communication object become visible. The object value is "ON" if at least one group or a single device of the DALI system concerned is switched on (brightness value > 0). The object value is "OFF" if all the groups or single devices are switched off (brightness value = 0). Here, it is not important what switched a group or individual on or off. A KNX command on objects of the groups or single devices or the recall of a scene, for example, cause the function to be updated.

When the standby switch-off is evaluated, the logical switching status of a group or single device is evaluated. It is irrelevant whether all or individual projected groups or devices were assigned electronic ballasts during DALI commissioning, or whether assigned electronic ballasts can be controlled.
