Type C – 4-bit: button short pressing = open/close; button long pressing = step;
falling edge = stop
– this scheme differs from the “Type A – 1-bit” scheme in that each
long press changes direction to which slats are adjusted / shutters are moved, and the
falling edge (button release) stops them. The “FB 1: shutter – Stop/step up/down”
communication object may assume 4-bit values, and in the “Open: step value” and
“Close: step value” fields you can define values by which slats are adjusted / shutters
are moved during the step up / down.
In the case of two-channel mode, you can select:
Type A – 1-bit: button short pressing = step/stop; button long pressing – open/close
Type B – 1-bit: button short pressing = open/close; button long pressing = step/stop
Type C – 4-bit: button short pressing = step; button long pressing = open/close
Type D – 4-bit: button short pressing = open/close; button long pressing = step;
falling edge = stop
Events from the first channel (“Open: control channel”) will start the shutter moving up
and trigger stepwise slat adjustment / shutter movement in the same direction. Events
from the second channel (“Close: control channel”) will start the shutter moving down
and trigger stepwise slat adjustment / shutter movement in that direction. The scheme
defines which event will trigger movement and which will adjust the slats / move the
shutter by one step up / down, depending on the channel in which it is generated.
Falling edge (button release) in the channel will stop movement of the slats / shutter. If
you select the “Type C” or “Type D” scheme, the “FB 1: shutter – Stop/step up/down”
communication object will be a 4-bit object. The fields will be displayed in the tab in
which you can define the step value up (“Open: step value”) and down (“Close: step
value”).
The two-channel control can only be properly implemented when two different
channels are selected in the “Open: control channel” and “Close: control channel”
fields.
“Type C – 4-bit” (one-channel control) and “Type D – 4-bit” (two-channel control) are
dedicated schemes for shutter movement control by using physical channels. It is
recommended for these schemes that the step value for movement up and down be
set at 100% (“Open: step value” and “Close: step value” fields). Thus the stepwise
movement of slats or shutter will only be stopped after the button is released by the
user.
Please remember that the binary input module enables the signals from outside of the
KNX system to be changed into control telegrams for other devices on the bus (e.g. for
roller shutter/blind actuators), but interpretation of these telegrams depends on how
these devices/actuators are configured.
