How many DALI devices can be dimmed in parallel with the DG/S 1.1 in a KNX group?
In the DG/S 1.1, all devices on the DALI side are always processed individually. Should several devices be dimmed in parallel using the KNX, then the number of devices must be limited to max. six. Why? Through serial processing of the devices on the DALI side, a brightness offset can occur during or after the end of a dimming process. This becomes visible especially in case of “Up, Down” dimming commands occurring in rapid succession. The offset is also recognizable when status messages are active.
