To be able to access KNX, the KNX PS640-IP requires an additional physical address.
This second physical address is only used for bus access and must be set up separately:
Select the “Communication” tab under Extras -> Options in the ETS. The
communications interface is the connection that is currently configured. Click on
Settings…
to open the following window:
Enter a physical address of your choice. This address should lie in the same topological
line but should not be in use by another device.
A dummy device may have to be added to the ETS project to reserve this address.
