4.4.1.1 LED Orientation light
The LED is located in the centre of the upper part of the button. When activated, the LED always lights up
green.
There are 4 selection options for the control. On the one hand, the LED can be switched permanently
"OFF". This deactivates the LED and it has no further function.
If the LED is to be used as an orientation light, for example, the LED can be switched on permanently via
the "ON" setting. Furthermore, the LED can be controlled via an external object. In this case, the polarity
for switch-on/switch-off can also be set.
When controlling via an external object, an additional communication object is displayed, which can then
be linked with any other 1 Bit communication object.
The following table shows the available communication objects:
Number Name / Object function
* 49/69/89/109 LED Orientation light – Switch
Table 34: Communication objects – Orientation light
* Object numbers depend on the device version (number of buttons).
