Recorded telegrams can be saved, opened, cleared and replayed.
Saving telegrams
It is possible to save recorded telegrams via the button 'Export' in the toolbar of the Bus/Group Monitor window. It is possible to save recorded telegrams without stopping the recording. ETS will prompt to save either 'all telegrams' or only 'the selected telegrams'. You can export the telegram as an XML file allowing you to edit the stored telegrams by means of an XML editor, or you can save the telegrams in CSV format, which can then later be viewed and edited by programs such as Microsoft Excel and similar.
CSV export is meant for direct reading by humans or to be used by software which does not understand KNX (e.g. Excel). XML export is more-or-less ETS internal. The data is not 'encrypted', but just the raw cEMI frame as HexBinary.
Opening telegrams from file
Saved telegram recordings can be opened via the 'Import' button, which can be found in the Bus/Group Monitor toolbar. ETS can display files with the extensions '*.xml, *.trx (ETS3) or *.hlg (ETS2)'.
Clearing the telegram list
The list of previously recorded telegrams can be deleted via the 'Clear' button, which can be found in the Bus/Group Monitor toolbar.
Replaying telegrams
In order to verify more complex processes, ETS also allows replaying of telegrams previously recorded and saved to a file. This is only possible using the Group Monitor.
In order to replay the recorded telegrams, make sure that the PC is connected to the bus and press the Start button before pressing the 'Replay Telegrams' button. The 'Play Telegram Options' window is opened: select the file via the 'Search' button. It is possible to:
- 'Play as recorded' which plays the telegrams 1:1 according to the recorded trace (default setting) or
- 'Play without delay'. This is the best option when the time interval between recorded telegrams in the selected file is quite long.
Stop replay
You can use the 'Stop Replay' button when you want to stop telegram. This functionality is only available when using the Group Monitor.
