There must be a utility from IAI to do that.
It is not in TIA since it is not from Siemens.
Apart from that, you need to setup also the Device Name in the IAI device, the "IAIStn2n3".
Some PN IO Devices support that the IP adress is sent from the PN IO Controller. But if you dont know if the IAI device support that, then set the IP address as specified in the TIA project.
