Table 18: Settings - Brightness
In the menu "Brightness" the transmission conditions for the measured brightness value can be
defined. The measured brightness value can be transmitted both at a certain change and at certain
intervals.
In addition, a threshold value switch can be set for a specific brightness. This can be set with a
hysteresis that avoids too frequent switching. The interplay of hysteresis and threshold value is
illustrated in the following diagram:
Figure 21: Hysteresis - threshold switch
The polarity and the transmission conditions can be defined as desired with the other parameters.
Both, the polarity and a transmit filter can be set.
The following table shows the relevant communication objects:
Number Name Length Usage
66 Threshold switch 1 Bit sends the set value at exceedance/shortfall
67 Status brightness value 2 Byte measured brightness value
