KNX function "Venetian blind"
For each rocker or button with the function set to "Venetian blind", the ETS indicates the two 1-
bit objects "Short-time operation" and "Long-time operation".
Operation concept of the Venetian blind function
For the control of Venetian blind, roller shutter, awning or similar drives, the device supports the
"short - long" operation concept.
Figure 5: Operation concept "short – long"
In the operation concept "short - long" the telegrams are transmitted in a specific time
sequence...
-
Immediately on pressing the rocker switch or button, the device transmits a short time
telegram (step) to the bus. Pressing the button stops a running drive and starts time T1
("time between short time and long time command"). If, within T1, the button is released
again, the device transmits no further telegram. The purpose of transmitting the short time
telegram is to stop a continuous movement.
The "time between short time and long time command" should be selected shorter than the
short time operation of the actuator to prevent a jerky movement of the blind.
-
If the rocker switch or button is kept depressed longer than T1, the device transmits a long
time telegram after the end of T1 (Move) for the continuous movement of the drive.
-
No further telegram is transmitted by the device when the button or the rocker is released.
The drive remains on until the end position is reached.
Command of the Venetian blind function
The parameters "Command on pressing the button" and "Command on pressing the rocker
switch" define the command transmitted to the bus on pressing a button. In a rocker switch, the
configurable commands for both actuation pressure points are always contrary (at the top: UP /
at the bottom: DOWN, at the top DOWN / at the bottom: UP). The commands can be allocated
arbitrarily for buttons.
KNX function "Value transmitter 1 byte"
For each button with the function set to "Value transmitter 1-byte", the ETS indicates a 1-byte
communication object. On pressing a button, the value configured in the ETS is transmitted to
the bus.
The "Function" parameter determines the value range used by the value transmitter.
As a 1-byte value transmitter, the push button sensor can optionally transmit integers from
0 … 255 or relative values within a range of 0 … 100 % (e.g. as dimming value transmitter).
The value matching these areas to be transmitted to the bus on pressing a button, can be
configured by the parameter "value on pressing the button".
i
The function "Value transmitter 1 byte" is only available for buttons.
