• Full or partial reading of the programmed devices of an EIB/KNX system with parameter settings and Group Address assignments.
  • EIB/KNX systems that were created with ETS1, ETS2 or ETS3 can also be read if the product data (VDX oder KNXPROD format) are available.
  • Comparing the read data with the configuration data.
  • Conversion of the data read into an ETS project. This allows lost or unavailable configuration data to be restored.

New features from Version 5.0.1516!

  • easy search for product data
  • new online service of the IT GmbH
  • reconstruction of modern “modular” application programs
  • support for segment couplers and KNX Secure devices
  • recognition of coupler products


These data can be reconstructed:

  • Topology (areas and lines)
  • Devices
  • Individual Address
  • Used Application Program
  • Parameter settings
  • Communcation object flags and priority
  • Assigned Group Addresses

These data cannot be reconstructed because they are not programmed into the devices:

  • Building and function structure
  • Names and descriptions of areas, lines, devices and Group Addresses

In some cases, reconstruction may be incomplete or fail:

  • Devices locked with an unknown BCU password may not be readable.
  • Devices that are programmed with plug-ins (additional software) can only be read out and reconstructed if the device manufacturer supports this (with a corresponding reconstruction plug-in).
  • Some Application Programs contain parameters that are not programmed into the device (e.g. comments on the documentation). These functionally insignificant parameters can therefore not be reconstructed.
  • It is possible that there are Application Programs whose complex parameter dependencies cannot be completely resolved by Reconstruction. It will then issue a corresponding message. In this case, please contact our support. We will then try to find a solution.

For information on reconstruction specifically for ABB products, please refer to this document from the manufacturer.

We have prepared a list of IDs for manufacturers of KNX devices for you.

Customers who have purchased our app Reconstruction receive additional assistance. The following links provide you with overviews (TXT files – as of March 2019) that show the assignment of order numbers to application IDs. These overviews do not claim to be complete! Likewise, it is not guaranteed that you have really imported all possible applications if you have only imported a product with a specific order number. Especially older versions of the application programmes have often been removed from the product data by the manufacturers in favour of newer versions.

Missing product data can be imported (manually).

New! Online service of the IT GmbH

With the online service you have access to thousands of current and older product data. Currently data of more than 15.000 application programs are available. Products not yet present in the project are automatically searched for via the online service and can be downloaded directly from the Reconstruction app (ETS5) or even imported directly (ETS6).

For access you need a personalized key, which you can purchase via for a one-time payment of 100 EUR (plus VAT).

We put a lot of effort into the maintenance of this database and therefore ask for your understanding that the personalized key is only intended for the acquirer and may not be passed on to third parties!
