When you try to download some devices you get this error message
"Error message "DoA address has length of 0 but must be one of:2 (pl),6 (rf),4
or 21 (IP)"
and you are not able to configure them.
What to do:
- Uninstall ETS 5.7.3 (Your existing projects shall normally not be affected).
- Install ETS 5.7.2 (Download it from here).
- Open the project in which you have to program the devices and download them.
In case you have already opened your project with ETS 5.7.3 and you don't have a backup that can be opened with ETS 5.7.2, you can send us your project file, so that we can 'downgrade' it, in order to open it with ETS 5.7.2.
This issue will be resolved in the next ETS update (v5.7.4) in January.
