10.14.3 Extended parameters - Working mode of the buttons for switching
Options:
1st button off / 2nd button on
1st button on / 2nd button off
Alternating on/off
The "Working mode of the button for switching" application determines whether switching on or
switching off occurs via the right or the left side of the button. Using the behaviour "Alternating
on/off" always switches between ON and OFF. That means, for example, if an ON telegram was
last sent out, then a renewed operation of the rocker switch will trigger an OFF telegram. If the
button is operated again, an ON telegram will be sent again, etc. The button thus always
remembers the last state and then switches over to the other value.
This also applies for values that are received via the associated 1-bit communication object.
This means that if an ON telegram was sent out for the last button operation, thereafter an OFF
telegram was received via the communication object, the next operation of the button will send
out an ON telegram. It must be observed here that the S-flag (writing) of the communication
object is activated.
10.14.4 Extended parameters - Working mode of the buttons for dimming
Options:
1st button brighter / 2nd button darker
1st button darker / 2nd button brighter
The "Working mode of the button for dimming" determines whether operation of the left or right
side of the button will send out a dim brighter or a dim darker telegram.
If a dimming telegram is triggered by operation of the button, a dimming telegram will be sent
out on the 4-bit communication object "Relative dimming".
