The Reconstruction tool can be used to read out devices in the installation and then create a new ETS project or update an existing project. You may also compare the data from the installation against an ETS project.
This allows to work on projects where the ETS database has been lost or is out of date. This will also work for installations which were created with a previous version of ETS.

These items can be reconstructed: topology, devices with individual address, application program, parameter settings and group object flags, priority and assigned group addresses. You need bus access and same product data which were used to program the devices.
Building or trade structure as well as name and description texts of areas, lines, devices and group addresses will not be reconstructed because they were not programmed into the device.

Note: Devices with plug-ins can only be read out / reconstructed, if supported by the manufacturer of the plug-ins. In case of doubt please contact the manufacturer or our support.
Devices which product data cannot be used in the current ETS can not be reconstructed.

With the ETS App Replace Device, you can replace KNX devices while keeping their Group Addresses. This is possible for devices with similar functionality, regardless of the manufacturer.

Shift Addresses helps you to re-structure Group Addresses and Individual Addresses in an ETS project, e.g.
- Shift addresses to make room for a new function but still keep an established addressing scheme
- Create gaps between addresses to allow for future extensions or to produce a clean and logical addressing scheme

With the ETS App Split & Merge, a project can be split into two, three or more parts. Several ETS users can edit them independently and merge again them after completion of the entire project. This works also with unrelated projects, so that it can be merged.

With terminal-App you can import KNX projects from terminal, the universal online configurator.
In addition to the requirement specification generated by terminal, you can import floors, rooms and group addresses directly to your ETS project. Terminal-Konfigurator
