﻿At this point, the brightness value can be specified that is set when the device is switched on.

*Brightness value*: The set brightness is set when receiving an ON telegram via the communication object "Switching - Setting" or when receiving a central telegram with the polarity "activated".

*Memory value (brightness as before switching off the last time)*: When switching on, the brightness value is set that was active and stored internally before switching off the last time. This memory value is stored in a non-volatile manner in the gateway so that the value is retained after the bus or mains voltage returns. After an ETS programming operation, the memory value is predefined to "100%". This value is optionally limited by the maximum brightness.
