The KNX I/O Server provides for the control of a KNX installation compliant with the KNX Standard version 2.0.
The communication between HSYCO and the KNX network must employ a KNXnet/IP gateway supporting the Tunneling service.
The KNX framework must be programmed to work properly using the ETS tool.
Each defined KNX group is seen as a datapoint whose value is formatted with respect to its DPT type. Supported DPT types range from DPT 1 to DPT 18. Moreover, it is possible to have virtual datapoints that link a set of datapoints used for the control of devices such as lights, dimmers, automations and thermostats which require several KNX groups for commands and feedback.

HSYCO Configuration
Add a KNX I/O Server in the I/O Servers section of the Settings and set its parameters:
Communication
- IP Address: IP address of the KNX/IP gateway
- IP Port: TCP/IP port to use, leave blank to use default port 3671.
High Availability
- Shutdown when inactive: defaults to false.
Options
ID | Default | Values | Description |
---|---|---|---|
startupevents | false | true | generate IO events also during the driver’s start-up phase |
false | start generating events only after HSYCO is aligned with the current status of the system | ||
discovery | true | true | automatically create the list of all detected datapoints with type DPT 1 and the defined virtual datapoints in the systemtopo.txt file. Should be enabled to allow the automatic update of (button) objects' states |
false | auto-detect for devices is disabled | ||
fromevents | false | true | generate events for commands sent on the KNX BUS reporting the source address and the value of the command |
false | disable command events | ||
readaftercommand | false | true | force the driver to read the value of a datapoint after a command is sent to it |
false | the driver will assume that commands detected on the BUS are always successful, thus no re-reading is performed to set the value of a datapoint | ||
localport | <port_number> | the port number used locally by HSYCO to communicate with the KNXnet/IP gateway. This option might be necessary when employing network address translation (NAT) | |
initreadinterval | 0 | <milliseconds> | Time interval, in milliseconds, between datapoint values reading requests during the initialization phase |
Datapoints Declaration
It is required to provide the I/O Server with the KNX framework configuration. To this end, the KNX Utility provides a graphical interface to import ETS4 or ETS5 project files and to configure the datapoints.
It is also possible to manually define the datapoints in the knxtopo.txt file.

Datapoint types and values
The KNX I/O Server supports all datapoint types (DPTs) listed in the following paragraphs.
The value of a datapoint is formatted with respect to its DPT main number. The actual behavior of the datapoint is anyhow dependent on its complete type (i.e. main number and sub number). Examples for the most common cases will be provided, but for a complete reference of all available datapoint types and allowed values we strongly advice to refer to chapter 3/7/2 of the KNX Standard v2.0.
The following paragraphs will show the KNX data format for each DPT as described in the protocol as well as the allowed datapoint values and the corresponding conversion.
Datapoint Type 1 (1 bit, Boolean)
KNX bit-level format:
b |
b = {0, 1}
Datapoint values:
Value | Converts to |
---|---|
0 | b = 0 |
1 | b = 1 |
Example:
For a datapoint with DPT 1.001 (e.g. a switch) a value of '0' corresponds to the 'off' state, while for a datapoint with DPT 1.007 (e.g. a step indicator for a dimmer) it would correspond to the state 'decrease'.
Datapoint Type 2 (2 bits, Control)
KNX bit-level format:
c | v |
c = {0, 1}, v = {0, 1}
Datapoint values:
Value | Converts to |
---|---|
disabled | c = 0, v = 0 |
0 | c = 1, v = 0 |
1 | c = 1, v = 1 |
Datapoint Type 3 (4 bits, Dimming, Blinds)
KNX bit-level format:
c | step |
c = {0, 1}, step = [000b ... 111b]
Datapoint values:
Value | Converts to |
---|---|
-7 ≤ v < 0 | c = 0, step = |v| |
0 ≤ v ≤ 7 | c = 1, step = v |
Example:
For a datapoint with DPT 3.007 (control dimming) a value of '3' corresponds to a 3-steps light increase. The same value for a DPT 3.008 (control blinds) datapoint corresponds to a 3-steps downwards movement. In both cases a value of '0' indicates the 'break' state.
Datapoint Type 4 (8 bit, Character set)
KNX bit-level format:
char |
char = [0 ... 255] (ISO 8859-1 encoding of a character)
Datapoint values:
Value | Converts to |
---|---|
0 ≤ v ≤ 255 | char = v |
A DPT 4.001 datapoint will only support the values corresponding to ASCII characters (a subset of the ISO 8859-1 standard values), thus only values ranging from 0 to 127 are allowed.
Datapoint Type 5 (8 bits, Unsigned Value)
KNX bit-level format:
val |
val = [0 ... 255]
Datapoint values:
Value | Converts to |
---|---|
0 ≤ v ≤ 255 | val = v |
Example:
For a datapoint with DPT 5.001 (scaling) a value of '255' corresponds to '100%'. For a datapoint with DPT 5.003 (angle) the same value corresponds to '360°'.
Datapoint Type 6 (8 bits, Signed Value)
KNX bit-level format:
val |
val = [-128 ... 127] (two’s complement notation)
Datapoint values:
Value | Converts to |
---|---|
-128 ≤ v ≤ 127 | val = v |
Datapoint Type 7 (2 Bytes, Unsigned Value)
KNX bit-level format:
val |
val = [0 ... 65535]
Datapoint values:
Value | Converts to |
---|---|
0 ≤ v ≤ 65535 | val = v |
Datapoint Type 8 (2 Bytes, Signed Value)
KNX bit-level format:
val |
val = [-32768 ... 32767] (two’s complement notation)
Datapoint values:
Value | Converts to |
---|---|
-32768 ≤ v ≤ 32767 | val = v |
Datapoint Type 9 (2 Bytes, Float Value)
KNX bit-level format:
m | e | m |
e = [0 ... 15], m = [-2048 ... 2047] (two’s complement notation)
float value = (0.01 * m) * 2^e = [-671088.64 ... 670760.96]
Datapoint values:
Value | Converts to |
---|---|
-671088.64 ≤ v ≤ 670760.96 | float value = v |
Datapoint Type 10 (3 Bytes, Time)
KNX bit-level format:
day | hour | 0 | 0 | min | 0 | 0 | sec |
day = [0 ... 7] (0 = no day, 1 = Monday, ..., 7 = Sunday)
hour = [0 ... 23]
min = [0 ... 59]
sec = [0 ... 59]
Datapoint values:
Value | Converts to |
---|---|
<day>.<hour>.<minutes>.<seconds> | day = <day>, hour = <hour>, min = <min>, sec = <sec> |
Example:
A value of '2.12.46.23' corresponds to 'Tuesday 12:46:23'.
Datapoint Type 11 (3 Bytes, Date)
KNX bit-level format:
0 | 0 | 0 | day | 0 | 0 | 0 | 0 | month | 0 | year |
day = [1 ... 31]
month = [1 ... 12]
year = [0 ... 99] (if ≥ 90 interpret as 20th century, otherwise interpret as 21st century)
Datapoint values:
Value | Converts to |
---|---|
<year>/<month>/<day>
(1990 ≤ <year> ≤ 2089) |
year = last two digits of <year>, month = <month>, day = <day> |
Example:
A value of '2011/2/8' corresponds to 'February 8th 2011'.
Datapoint Type 12 (4 Bytes, Unsigned Value)
KNX bit-level format:
val |
val = [0 ... 4294967295]
Datapoint values:
Value | Converts to |
---|---|

float value = 0, [1.40129846432481707E-45, 3.40282346638528860E+38] (IEEE 754 floating point format)
Datapoint values:
Value | Converts to |
---|---|
v = 0 | 1.40129846432481707E-45 ≤ v ≤ 3.40282346638528860E+38 | float value = v |
Datapoint Type 15 (4 Bytes, Access)
KNX bit-level format:
d6 | d5 | d4 | d3 | d2 | d1 | e | p | d | c | index |
d1, d2, d3, d4, d5, d6 = [0 ... 9]
index = [0 ... 15]
e = {0, 1} (0 = no error, 1 = reading of access information was not successful)
p = {0, 1} (0 = not accepted, 1 = accepted)
d = {0, 1} (0 = left to right, 1 = right to left)
c = {0, 1} (0 = no encryption, 1 = access information encrypted)
Datapoint values:

Datapoint Type 16 (14 Bytes, String)
KNX bit-level format:
char1 | ... | char14 |
These Datapoint Types are used to transmit strings of textual characters. The length is fixed to 14 octets. The contents are filled starting from the most significant octet. Each octet shall be encoded as specified for the chosen character set. If the string to be transmitted is smaller than 14 octets, unused trailing octets in the character string shall be set to NULL (00H).
Example: “KNX is OK” is encoded as follows: 4B 4E 58 20 60 73 20 4F 4B 00 00 00 00 00
Datapoint values:
Value | Converts to |
---|---|
<string>
(max 14 bytes) |
ISO 8859-1 encoded bytes padded with trailing NULL bytes |
Example:
A valid value would be: 'Hello world'
Datapoint Type 17 (1 Byte, Scene Number)
KNX bit-level format:
0 | 0 | sn |
sn = [0 ... 63]
Datapoint values:
Value | Converts to |
---|---|
0 ≤ v ≤ 63 | sn = v |
Datapoint Type 18 (1 Byte, Scene Control)
KNX bit-level format:
c | 0 | sn |
c = {0, 1} (0 = activate the scene, 1 = learn the scene)
sn = [0 ... 63]
Datapoint values:
For this case the datapoint syntax is slightly different. The scene number (sn) must be suffixed to the datapoint ID as follows: <datapoint_id>.<scene_number>.
Value | Converts to |
---|---|
record | c = 1 |
1 | c = 0 |
Example:
The activation of scenario 12 on a datapoint would correspond to: <datapoint_id>.12 = 1
Datapoint Type 29 (8 Bytes, Electrical Energy)
KNX bit-level format:
val |
val = [-9223372036854775 ... 9223372036854775807] (two’s complement notation)
Datapoint values:
Value | Converts to |
---|---|
-9223372036854775 ≤ v ≤ 9223372036854775807 | val = v |
Datapoint Type 232 (3 Bytes, RGB)
KNX bit-level format:
R | G | B |
R, G, B = [0 ... 255]
Datapoint values:
Value | Converts to |
