Table 109: Settings - Mode selection
Function principle:
The function "mode selection" can send up to 4 different operating modes by shortly pressing a
button. The operating modes are switched one after the other. Depending on the set parameters, for
example, at a keystroke the second operating mode is sent if the 1st operating mode has been sent
before or the third operating mode will
be sent if the second operating mode has been sent before…
Parameter “Long push button”:
In addition to switchover by a short keystroke, a fixed operating mode can be sent at a long
keystroke.
Here one of the 4 operating modes can be sent. This means that a fixed operating mode
(independent of the last switching value) would always be sent with a long keystroke.
Parameter “Switching type”:
Limit stop:
With the switching type "Limit stop" the 4th operating mode is sent again after sending
the 4th operating mode.
Overrun:
In the switching type "Overrun", the 1st operating mode is sent again after the 4th
operating mode.
For the single-button function, this parameter is set permanently 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.
