IP CONTROL CENTER N152 - IP Tunneling not working

Hello all,

I am using IP CONTROL CENTER N152 and I can't use IP Tunneling to download, with ETS 5.5.2, the applications to other KNX devices in the project. Testing the interface, that is automatic discovered, I get following message :

'The interface is currently used and does not accept more connections'

In the beginning of the installation I used the N152 without any problem, but when I downloaded the KNX application (KNX Address and application)  I lost the connection.

Any ideas ?

It´s a typical problem when the physical KNX address of device and the phys. KNX adr. of integrated KNX interface are identical. The two addresses have to be differently. You can check it in ETS configuration settings. With using the Siemens KNXnetIP Diagnostic Tool you can fix that problem.
