Is it possible, using the IP network, to assign a physical address directly to an IP Router IPR/S 3.1.1?
The Router can be physically addressed and loaded with the application from the KNX side, as well as using the IP network. But it should be noted that the application data are adopted only after a reset. A reset is automatically triggered after a download.
