TalKNX L

This driver is for the TalKNX L (old KNiXPort V3+) central KNX control system using the TCP interface module.

This module can handle up to 1000 data points.

TCP Connection

The TCP connection on the KNiXPort interface should be connected in the same network as the XP-3/6/8.

You can enable a keep alive heartbeat for the driver which will be necessary in an absence of KNX devices which are sending their values periodically into the KNX bus (like weather stations or thermostats).

To avoid a high CPU load at start up you can specify a delay which force the driver to wait for the given time in seconds.

Weather

Use this to tell the driver which data points are weather data points especially those using image list data sources. The wind is using the Beaufort scale and requires an image list containing 13 images.

It is possible to use up to 3 luminance data points. Enter the data points separated by commas. If you want to change the image list data source for the luminance display make sure it contains 11 images.

Examples:

DP Weather Sun: "1,5,8" - Using data points 1, 5 & 8.

Light Sliders

To use a graphic slider for adjusting the dimmer level of a particular light, use the Light Set Dimm Value (Slider) command (1Byte in KNX). If it is a switch, use Light Set On/Off (Slider Switch) command (1Bit in KNX).

Light Buttons

You can also use the Light Dimm Up resp. Down and Light Dimm Stop Commands on Buttons (4Bit in KNX).

There are single commands for On Off and Toggle (1Bit in KNX).

Scene Control

To select a scene, use the Scenes-SelectScene command, for saving a scene the SaveScene command (6Bit in KNX).

AUX Buttons

To send non predefined commands, use the AUX-SendAux command (1Byte in KNX) or the AUX-Send2Bytes command (2 Bytes in KNX) or a AUXFloat command (2Bytes).

To send a string (max 14 Byte) value, use the AUX-SendString command with a max 14 byte long string as parameter.

Blind Control

To raise or lower a particular blind, use the Blind Up and Blind Down commands and the Blind Lamelle command to stop (1Bit in KNX).

If the used actor can set the blinds to a defined position, use Blind Set Position command with position (1Byte in KNX).

Heat Control

With Heat-SelectMode (4Bit in KNX) you can select the mode for the heating control unit and with the Slider and Heat-SetBasisTemperature (Slider) you can adjust the Set Temperature of the control unit by changing the Basis Set Temperature (2Bytes FloatingPoint in KNX).

If you want to use Buttons(Up/Down) to change the temperature use the function ChangeTemperature (Up/Down) with Set Temperature Change Data point and it’s Return or

the ChangeBasisTemperature (Up/Down) with Basis Set Temperature (2Bytes FloatingPoint in KNX) and it’s Return.

Variables

There are 4 variables for each data point. The IntegerValue directly gives the value of the data point without any conversion:

1 Byte range: 0..255

1 Bit range: 0..1

2 Bytes range: 0..65535

The BooleanValue returns a “False” when the value of the data point is equal to 0, else it returns “True”.

The FloatValue is originally an integer value and contains the floating point value multiplied by 10.

You can use this for all 2 Byte floating point values of the KNX, as temperature or wind velocity.

The StringValue returns a string with a maximum of 14 characters.

Additionally the IntegerValue has a format string included which gives the value in percent. If the value is 100 the displayed value will be 39%.

Events

There are 150 events you can use. You have to parametrize the data point, the value for the threshold and the type of the event:

value above an event will occur, when the value is above the given threshold

value below an event will occur, when the value is below the given threshold

value equal event will occur, when the value is equal the given threshold

The threshold must be given in an IntegerValue which contains the original value multiplied by 10.

Examples:

DP contains a value of 1 Byte Use 1280 as threshold for original value of 128

DP contains a value of 2 Bytes Use 225 as threshold for the value 22.5.

Additionally there are indication events for each data point which are signalled, when the value was updated from the KNX bus.

For a Watchdog functionality 50 Dead and Alive events are added.

System variables from other drivers

There are 30 system variables from type string, 100 from type boolean and 30 from type integer you can use. You can enter a list of those data points, where the value of the variable will be sent to when the value changes. In case of Boolean a “1” will be send when the variable is “true, a “0” otherwise.

Examples:

Data Points 1: "16,26" - Using data points 16 & 26.

Scene Support (e.g. for Dali)

There are 50 scene data points with scene numbers you can use. You can enter a list of those data points, which values you want to save or send in case the scene is saved or called in KNX. All scene numbers of the selected scene Data point must be controlling the same actuator data points added in that list. Both lists have to be of the same length or if the second list is empty, the same data points as in the first list will be used.

Examples:

Scene Data Point 1: "35" – data point to listen to scene calls or scene saves.

Data Points listen to 1: "16,26" - Using data points 16 & 26 to save their values.

Data Points written to 1: "17,27" - Using data points 17 & 27 to send saved values to.

Value manipulation

Use this to tell the driver which data points values should be scaled into the range 0..100 or 0..10. The Scaling up to 100 will set the output variables into the range from 0 to 100, Scaling up to 10 into the range from 0 to 10. You can use the last settings to provide an image list containing 11 images.

Please make sure that the data points you are using with this functionality are 1 Byte values and be aware that the corresponding variables will contain the manipulated values only.

Example:

DP Scale up to 100: "1,50,88" - Using data points 1, 50 & 88.
