The example shows a configuration in which the short and long button press events from the
physical channel A control the lighting (which events change the state of individual
communication objects depends on the mode and control scheme selected when configuring
the function block 1). At the same time, these events are the pair of events to control the
timer channel A, where the short button press enables and the long button press disables this
channel. When enabled, the timer channel is changing its state cyclically within the defined
time intervals (see “Timer channels”). Thus, the channel generates events that control the
switching sequence (Function block 2: Sequence), where short presses trigger consecutive
steps in the sequence (switch the state of consecutive objects) and long presses change
switching direction in the sequence.
4.7.3 Using virtual and logic channels
The example shows a solution in which telegrams received from the KNX bus by the “Virtual
input – Input A” communication object are converted in the virtual channel A into events that
are handled by the module. This enables these telegrams to be linked to signals from outside
of the bus. Short and long button press events from the virtual channel A control the shutter
(Function block 1: Shutter). At the same time, long button press events from this, together
with short button press events from the physical channel A control lighting (Function block 2:
Dimmer). Which events change the state of individual communication objects depends on the
mode and control scheme selected when configuring individual function blocks. The example
shows also how the state of virtual channel A and the state of physical channel A are linked
to each other in the logic function defined in the logic channel A. As a result of this link, short
button press events that control switching (Function block 3: Switch) are generated in the
logic channel.
