This tutorial shows how to create a simple web visualization can be created. To use this tutorial, please do the following steps in advance:
- Install the NETx BMS Platform, which includes BMS Core Server and Visualization Editor.
- Prepare a KNX project and export the ETS project using our NETx BMS app. The data points of this project shall be used within this tutorial.
| Info |
|---|
Although it is using KNX data points, this tutorial can of course be used with other technologies like BACnet or Modbus. |
After having installed the NETx BMS Core Server, a new project called workspace has to be created. A workspace contains the whole configuration of a BMS server project. To do so, start the NETx BMS Studio and select the entry "New ..." within the "Workspace" menu.
Give the workspace a name (e.g. "Tutorial"). Afterwards, a new workspace is created and the NETx BMS Core Server is restarted.
Import the KNX configuration data from the ETS
One advantage of KNX is that each KNX project is engineered using the engineering tool software called ETS -- independent which devices and which vendors are used within the KNX project. Therefore, the ETS holds the whole configuration data and is thus an important knowledge base for the NETx BMS Core Server. To ease the data exchange between the ETS and the NETx BMS Server, an ETS app called NETx BMS App is available. Using this app, the whole KNX configuration can be exported from the ETS and imported within the NETx BMS Server.
Import the export file (.nxe) of your KNX installation into the NETx BMS Server using the entry "Import NETx ETS app file ..." within the menu "KNX" of the NETx BMS Core Server.
Select "Replace current definitions" and step through the wizard. After having finished the import, stop the NETx BMS Core Server and start it again. Verify whether the KNX connection is working and whether you can control your KNX data points within the Item Tree of the NETx BMS Core Server.
Creating a visualization project using the Visualization Editor
The Visualization Editor is a independent software to create and edit Visualizations. To create a new visualization project, start the Visualization Editor .Afterwards, the Visualization Editor starts. Then Connection Properties window will show up.

TLS Connection password.

Port,Password and PIN are defined in the BMS Core Server, Server , Server configuration |
Then User login with Username and Password. Default Username and Password are (admin, changeme). Then, the new project is opened and an empty visualization page is shown.

for a small KNX project. Requirements for this tutorial:
- NETx BMS Platform is installed including server-side components and Visualization Editor: Installation
- Use the ETS NETx BMS App Secure to create an export file of the ETS project: Tutorial: Import a KNX project from the ETS
| Info |

Although this tutorial deals with KNX data points only, the procedure can be applied to any kind of data points available in the Core Server. |
- Create a new Core Server workspace or open an existing one: Workspace menu
- Import your ETS project: Tutorial: Import a KNX project from the ETS
- Switch to the Visualization Editor and create a new workspace.
Create a visualization page for floor 1
First, rename the visualization page to "Floor Plan" by selecting "Properties..." within the menu "Page".
As next, a background image shall be placed on the visualization page. To do so, select "Image" from the object catalog at the left hand side and drop the element on the empty page.
Then, choose the image of the Floor . Double-click the image and select the Floor image. Afterwards, change to the tab "Position/Layer" and enter "0" for "Top" and "Left" and select "Background" as layer (the "Background" layer is the last layer within the list). Now the image is moved to the top left corner and fixed to the background.
...
| Info |
|---|
The visualization software is using the concept of layers. A layer is a group of elements. Layers are independent of the visualization page - they are defined for the whole visualization project. Each layer has four properties that can be changed via the view "Layesr", in View, Layers
As seen at the end of the layer list, the flags "Enabled in editor" and "Enabled in visualization" are deactivated for the background layer. Therefore, the background image cannot be moved anymore. |

Create a page for the second floor and add a link between the two pages
Create a new page by selecting the entry "New ..." within the menu "Page". Give the page a name and select "Ok". Repeat the steps from the last section to place a background image on the new page.
To create a link between the pages, move back to the first page and drag & drop a "Link Area" from the object catalog on the visualization page. Resize the link area and move it over the stairs of plan floor.And select the ID of the Floor.
Start the visualization by pressing the "Start" button within the tool bar and test whether the navigation between the two pages are working.
Create a navigation bar using a master page
Within most visualization projects, there will be elements that shall be shown on multiple pages. A typical example is a navigation bar that includes some buttons that shall be displayed on all pages. To avoid that these elements have to be copied to each page, the concept of master pages is provided. A master page acts like a template for visualization pages - all elements that are placed on the master page are also shown on other pages which are configured to use this master page.
Create a new page called "Master page". Within the configuration dialog, select the option "Is master page".
Then place a "Back" button on the master page. In addition to create your own buttons, some predefined buttons are already provided within the library. Select "Library" from the object catalog, choose a color theme, and place a "Button-Back-Rect" button on the bottom left corner. Double-click the button, change to the "Object" tab and select "Go to page" as function. As "Linked page" select "Navigate back". Change to the "Position/Layer" tab, change the width and height to "70" and close the dialog.
Afterwards, change to page "Floor2" and open the page configuration dialog. Within this dialog, select "Use master page" and close the dialog again. Do the same for the other page. As a result, the back button of the master page will also be shown on the other pages.
