ETS5 - Cannot programm components

[Kredatter]

Shuldigung auf Englisch zu schreiben, mein Deutsch ist nicht so gut.


I am programming my KNX installation (all components are already a few years old) and I encounter a strange problem.
I can program my IP gateway, but the moment I want to connect to a component I can't connect.
My setup:
- Jung IPS 100 REG - IP gateway
- K-BUS KI/U 0401.1
- K-BUS KP/D 30.640.1

When I do a download all of the IP gateway, it all works. If I do it for the 0401, it hangs on Please press programming button.

Attached are a few config screenshots.

Anyone has a magic hint?
Thanks!

The IPS 100 REG IP interface needs the newest firmware to be compatible with ETS5.

Thanks!
However I also tried with an ETS4 install and I had the same problem.
But I will try tonight!

I did not manage to find the update file or how to update this component.
So I was playing more in ETS4 and I remain on the same issue.
I checked the bus voltage and physical connections, they are all OK.
