Technical Manual
Push-button 55 / Plus 55 [BE-TA55xx.x2]
LED reacts to: internal object
With this selection, the object number to which the LED is to be linked is selected. For example, if the LED
is to switch when (with setting: button 1 to "Toggle") the "Object 1 - Status for Toggle" has the value "1",
the object number 1 must be entered. In this case, the status LED would be switched on with a logical "1"
and switched off with a logical "0".
If the LED is linked to an object that does not have the size 1 Bit, the LED is switched off if the object has
the value "0" and switched on if the value of the object is "not 0". For an object of the DPT 5.001 - percent,
this means that the LED is switched-off at 0% and switched-on at all other values.
LED reacts to: button activation
This selection causes the LED to react to the activation of the respective button. The action of how the LED
should react to a pressed or not pressed button can be configured via the parameter "LED display
behaviour". The value for "ON" is sent when the button is pressed and the value for "OFF" when the button
is not pressed.
The LED display behaviour for the respective state is defined via the parameters "for value "ON" and "for
value "OFF". Here, the LED can be green, red or off (not active). The setting "Behaviour for value "ON""
can also be used to specify whether the LED should hold the colour value permanently or whether it should
flash alternately.
The following table shows the available communication objects:
Number Name / Object function
* 32/52/72/92 LED 1 – Switch
Table 37: Communication objects – Switch object for LEDs
* Object numbers depend on the device version (number of buttons).

4.4.2.1 Priority

The LED priority can force the status LED into a defined state and thus override the control via an external/
internal object or the button press.
As long as the LED priority is active, the configured state for the LED priority is maintained and the LED
does not react to the "normal" control via external/internal object or button press.
When selecting "active, if object LED priority value = 1", the priority is activated with a logical "1" and
cancelled with a logical "0".
When selecting "active, if object LED priority value = 0", the priority is activated with a logical "0" and
withdrawn with a logical "1".
