That would be the Rx3i rack-mounted Profinet scanner IC695PNS001.
Edit:
I just created a new CPE400 project under PME 9.5 and I think I understand your question now. To add a Profinet drop, right click on the Profinet item in the project tree in the navigator window and then click "Add IO Device". Then expand the last "Rx3iPNSxxxxxxx" item in the list and select "7 Slot (Slot1) PAC Systems Rx3i Profinet IO Scanner".
My understanding is that each of the Rx3iPNSxxxxxx items corresponds to a firmware version. I'm not sure whether or not the firmware gets automatically updated when you download the hardware configuration with the network cable connected. In the system I recently commissioned, I used VersaMax Profinet scanners rather than the RX3i scanner. I selected the last scanner in the list and everything worked fine, but that could have been dumb luck.
