Integration of EIB/KNX sensors

This example shows how an EIB/KNX sensor with the status LED in the ETS must be parametrized, because this can be used in COMEXIO.

 

After the connection to the EIB/KNX subscriber has been created with the ETS, set up a new project. Here you create your topology and add your devices.

As usual, program your physical address in.

Now you need to parametrize your subscriber. In our example, it is an EIB/KNX glass button from MDT (BE-GTT4S.01). This is parametrized as follows.

 

Step 1. Set all buttons to active ("Individual buttons").

Info: For each button in COMEXIO to be used freely, you should always set the buttons to "Individual buttons".

 

 

 

Step 2. Parametrize buttons 1-4 as follow

Function:                                     „Switch“

Sub-function:                             „Send value with both button functions“

Value for actuated button:             1

Value for released button:        0

 

Info: These parameters are important so that a conventional button can be modelled and a data point is freely available as an input in the graphic programming.

 

 

 

Step 3. Status LED parameters

Activate the appropriate LED, LED X reacts to an "external object".

 

 

Info: These parameters are important for COMEXIO to access the status LED freely.

 

 

Step 4. Set up group addresses

Tip: Set up a main group with a name such as z.B. "GF button". Here add a middle group, such as z.B. "living room".For the sake of an overview, in the middle group "Living room", create two groups with "button" and "status" for each button.

 

 

Important: You need a separate address for identification, for each parameter, i.e. in the case of each button and status LED.

 

As soon as each function has been assigned to the group addresses and you have loaded the application to the device, all settings are completed with the ETS.

 

 

 

Step 5. Integrating EIB/KNX button in COMEXIO OS

 

Open the menu item"EIB/KNX / 1-Wire"

 

 

The following window opens.

 

In this window, two tabs are available. The EIB/KNX tab is automatically open. To integrate 1-Wire sensors, click on the tab to change. More on this in the "1-Wire"

Step 6. Turning on EIB/KNX learning mode

 

To integrate participants into COMEXIO OS EIB/KNX, confirm the EIB/KNX monitor using the “Switch on” button.

All active subscribers that send a telegram appear.

 

 

 

1. All EIB/KNX devices already added are listed here; these are then provided in the graphic programming under the respective "ID".
2. Name: Enter a name that simplifies assignment of the button. (e.g. “Button 1 living room”)
3. Type: For a button, here you select the type “Binary” for a temperature measurement, the type floating point numbers 2 bytes (optional setting).
4. Sub-type: For one button, make the selection “binary value”.
5. Data: Here the current data point is shown (“0” for released button, “1” for pressed button)
6. Extended view: When the tick is set, a further column called “Special“ appears. Here you can optionally adjust sending options.
7. Auto pre-selection: If this is activated, only the applicable type appears in the "Type" field (no selection option). 

 

To integrate the status LED, you can actuate the button “Add manually”. The following menu window appears.

 

 

 

Just take the data to be entered from the ETS. Enter the data in the window and save.

 

 

 

In the graphic programming, after saving the data point, you are provided with the ID 6; this data point is indicated by “K&”.

 

 

 

Step 7. Creating logical links

Example: Lighting is turned on and off with an EIB/KNX button through a COMEXIO output. Feedback on the switching status of the output comes through the button’s status LED.

Add the necessary data points and logic components to the logic diagram and connect them appropriately.

Test your programming by clicking once on the Start button to activate it.
