Polarity
– defines how the channel logic state will change in response to a signal change on
physical input (

Time of button short pressing (n * 10 ms)
– time that must elapse during a change of the
channel logic state from “0” to “1” and back to “0” for short button press to be generated in
the channel – see
Fig. 6
(0 – 255; default = 10). Button press duration is calculated as
product of n * 10 ms, where: n = value entered in the field.
Time of button long pressing (n * 10 ms)
– time that must elapse during a change of the
channel logic state from “0” to “1” and back to “0” for long button press to be generated in
the channel – see
Fig. 6
(0 – 255; default = 100). Button press duration is calculated as
product of n * 10 ms, where: n = value entered in the field.
Behavior of manual override button
– behavior of the channel state manual override
button (to simulate changes on the physical input):
Monostable
– pressing the button changes the channel state, releasing the button
restores the previous state of the channel.
Bistable
– pressing the button changes the channel state.
4.4.2 Virtual channels
Enable events supported by the module to be generated based on the telegrams received
from the KNX bus. The channel virtual input can be the “Virtual input A…H” 1-bit
communication object or 1-bit function block object that has been activated in the program,
e.g. the “FB 1: switch – Short pressing (1-bit)” object. Changing the state of the object (virtual
input) generates events in the channel according to the scheme below:

rising edge
– when state changes from “0” to “1”.

falling edge
– when state changes from “1” to “0”.

button short pressing
– on receiving a telegram, regardless of whether or not it will
change the object state.

button long pressing
– receiving a telegram by the object triggers countdown of that
object monitoring time (“Time of button long pressing” field). If the object receives no other
telegram within that time period, a long press event is generated in the channel.
For each virtual channel, you can select a virtual input (communication object) and define the
channel polarity as well as long button press duration.
