Principle of operation:
The function "switching values/scenes" can send up to 4 different values by shortly pressing a button.
The values are then switched one after the other. Depending on the set parameters, for example, at
a keystroke the second switching value is sent if the 1st switching value has been sent before or the
third switching value will be sent if the second switching value has been sent before.…
The parameter "
Push button long
" can be used to send a fixed value for a long keypress in addition
to the changeover by a short keypress.
When selecting "
1. – 4. Switching value
", a fixed switching value (value corresponding to the
assigned switching values) is always sent when a long key is pressed.
The setting "
4th switching value if last 1st switching value, otherwise 1st switching value
"
represents a toggle function which switches between the 1st and 4th switching values. If the 1st
toggle value was transmitted last, the 4th value is transmitted afterwards. For every other value, the
1st switching value is transmitted.
The setting "
Send 0
" sends the value 0 to the switching object. If, for example, the data point type is
set to percentage, the value 0% is sent.
The setting "
On at second object
" or "
Off at second object
" shows another communication object
for the long keystroke. The fixed value ON or OFF is then sent to this object with the size 1 bit.
With the setting "
Time delay between scene switching
", the transmission of the telegram is delayed
by the set time after you press the key. If you press the key 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 first toggle value to the third toggle value without activating the second one - with a
delay time of 2 seconds - press the key twice within 2 seconds.
Parameter “Switching type”:
Limit stop:
When the switching type "limit stop" is activated, the 4
th
switching value is sent again
after the 4
th
switching value has been sent.
Overrun:
When the switching type "overrun" is activated, the 1
st
switching value is sent again after
the 4
th
switching value.
For the single-button function, the parameter is set permantly to “overrun”.
Parameter “Switchover considers status object”:
If the
status value is not taken into account
during the changeover, the button memorizes the last
sent value and sends the next or previous value on the next actuation without observing whether
another value has been sent to the object in the meantime.
If the
status value is taken into account
during the changeover, the next keystroke will send the next
higher or the next lower shift value - with respect to the last received status value. Example: the 2nd
switching value is set to 40% and the 3rd switching value is set to 70%. Now, after a received status
value of 50%, the value 70% is sent at next keystroke if the next switching value is to be sent and the
value 40% if the previous switching value is to be sent.
