Functional principle
This function can send up to 4 different values when a button is pressed shortly. The values are
toggled one after the other. Depending on the set parameters, for example, when the button is
pressed, the 2nd toggle value is sent if the 1st toggle value was previously sent and the 3rd toggle
value if the 2nd toggle value was previously sent.
The parameter "
Long keypress
" can be used to transmit a fixed value for a long keypress in addition
to the changeover by a short keypress.
If you select "
1.
–
4. Toggle value
", a fixed toggle value (value corresponding to the assigned toggle
values) is always transmitted when a long button is pressed.
The setting "
4. toggle value if last 1. toggle value, otherwise 1. toggle value
" represents a toggle
function which switches between the 1st and 4th toggle value. If the 1st toggle value was sent last,
the 4th toggle value is transmitted next. For every other value the 1st toggle value is transmitted.
The setting "
Send 0
" sends the value
“
0
”
to the switchover object. If, for example, the datapoint type
is set to percentage, the value 0% is sent.
The setting
”
O
N”
to second object
" or
”
OFF
”
to second object
" displays another communication
object for the long keypress. The fixed value
“
O
N”
or
“
O
FF”
is then transmitted to this 1-bit object.
With the setting "
Time delay between value switchovers
", the sending of the telegram is delayed by
the set time after the button is pressed. If you press the button again during the delay time, the next
toggle value is activated immediately and the delay time is restarted. If, for example, you want to go
directly from the 1st toggle value to the 3rd toggle value without activating the second one - with a
delay time of 2 seconds - press the key twice within 2 seconds.
Parameter “Switching type” (only available with two
-button function)
Limit stop:
With the switching type limit stop, the 4th toggle value is sent again after sending the 4th
toggle value.
Overrun:
With the overrun switching type, the 1st toggle value is sent again after the 4th toggle value.
Note:
For the single button function, this parameter is permanently set to
“
overrun
”
.
