Project Data Exchange helps you to transfer ETS project data like topology, Group Addresses and building structure by exporting and importing
* between ETS projects
* between ETS and other tools (e.g. CAD programs)

Compare your current ETS project with an earlier version of the project (knxproj file or restore point) and get a detailed list of all differences for each individual project element. Jump directly from the difference list to the corresponding element. Many options control details of the comparison.

With the ETS App Project Tracing, all changes made in projects (except changes that have been made by device plug-ins) are registered in chronological order and are locked with a password. This App can also serve to monitor the progress of projects under construction.

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This allows to work on projects where the ETS database has been lost or is out of date.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.
