Operation
KNX B4 Universal Interface
• Version: 13.09.2021 • Technical changes and errors excepted.
4.1. Binary Input Application
KNX B4 Universal
provides four binary input channels for contact scanning. They
can be used as single channels and pairwise combined for two-button functions. For
all functions the contact type can be set (NO or NC) and a locking function ("Interlock")
is available. Excluding the counter function also the differing between long and short
button press can throughout be set.
Combining two channels (A/B or C/D) enables the two-button functions "Dimming" and
"Shutter". In single channel mode, following functions can be assigned to a single
channel:
•
Switch (toggle, status, short/long)
•
Scene (1-bit scene, 8-bit scene with and without long button press saving
function)
•
Counter (8-bit, 16-bit, 32-bit)
•
Send value: Percent, Angle, Temperature, 2-bit, 8-bit, 16-bit
•
One-button dimming
•
One-button shutter
To reset an input channel´s counter, a telegram containing "0" or "1" must be received
by the corresponding communication object "Counter reset".
4.2. Programming
4.2.1. Programming of Individual Address and Application
To download Individual Address and/or ETS application the Programming Mode must
be activated. Successive pressing the Programming Button will turn on and off Pro-
gramming Mode. LED C lighting in red colour indicates Programming Mode is active.
To make a download and configure the device, an interface connection (IP, USB) to the
KNX bus system is required. When Programming Mode is activated, the ETS is able to
start the download.
The Individual Address can be assigned to the device by setting the desired address in
the properties window of the ETS. After starting the ETS download and then pressing
the Programming Button the device restarts itself.
