Push-button information
Communication objects
You can select the following communication objects:
On the “Push-button info” tab you can see which push-
button names in ETS correspond to which push-but-
tons on the device. The names assigned cannot be
changed.
Each time the button is pressed, the 1-bit object type
first inverts the object value and then transmits it to the
bus, in other words making a “0” into a “1”. If the same
button is pressed again, the “1” turns back into a “0”.
The device is thus switched on and off alternately. This
switching behaviour is called “toggling”.
For 1-byte object types, you can set two values, which
are transmitted alternately after each press of the but-
ton.
An update or change to the object values is possible via
the bus when another sensor switches the actuator
(e.g. via a two-way circuit or a central command). To
prevent “incorrect” toggling, the state of the actuator
(“1” or “0”) must be tracked in the push-button. To do
this, connect the group address of the second sensor to
the switch/value object of the push-button.
Two objects (1 bit / 1 byte) can also be transmitted in
any combination when the push-button is pressed.
Status indication
The status LED can:
• Be switched on or off continuously.
• Light up when pressed (for a long period), and go out
when released.
• Flash.
• Display the status of the switch/value object. When
the 1 byte object type is used, the LED lights up if val-
ue 1 is greater than zero.
• Display the status of the status feedback object.
