Hi,
maybe the following steps help to solve your problem.
1. Please download the current PROFINET controller package from our collaboration room. Currently version 4.5.2.0 is provided there.
2. Configure the IP address and subnet mask of the network adapter on ctrlX CORE (This is a X7, but that should not be relevant) via the network settings. Please note that the ip ranges must not overlap with other network adapters! Otherwise ip telegrams can be misdirected.
3. Select the configured network adapter on the Ethernet node in the PLC Devices tree via the Browse button
4. Download the configuration and scan the bus to assign ip addresses and names to the connected PROFINET devices.
Now the PROFINET controller should work as expected.
