Gate type (XOR gate)
The output is triggered on (1), if the two inputs are not equal.
Gate type (NAND gate)
The output is triggered on (1), if one or both inputs are switched
off (0).
Gate type (NOR gate)
The output is triggered on (1), if both inputs are switched off (0).
Gate type (XNOR gate)
The output is triggered on (1), if both inputs are equal.
Gate type (INVERTER)
Input on (1) is converted into output off (0). Input off (0) is con-
verted into output on (1).

KNX Long Frames
Standard KNX telegrams are limited to an APDU length of 15.
The APDU length is the number of bytes in the payload. A group
telegram holding a 14 byte string (KNX data point type 16) re-
sults in an APDU length of 15.
To increase the efficiency of KNX communication mainly for the
download an extended format has been defined. It can be used
to send longer telegrams on the bus. To use this feature it must
be supported by
The tool (ETS)
The bus interface (USB)
All couplers in between
The addressed device
ETS starting with version 5 is able to detect automatically wheth-
er long frames can be used and optimizes the download accord-
ingly.
The max APDU length of the KNX USB Interface and which is
used by ETS is 55. This length has been specified as require-
ment for new KNX system devices. An APDU length of 55 results
in total length of a KNX telegram on twisted pair of 64 bytes and
occupies the bus for about 90 ms.
The download is much faster if the USB interface is in-
stalled in the same line as the target device. With each
line coupler in-between the download time growths.
