What I don’t understand: The OPC UA IP adress settings in PLC next is: axcf1152-pnc. Why dosen’t it care about these settings?

Hello Fabian,
DNS-Name/IP-Address is the name of the network node the eUA server is to use in the server URI and in the endpoint URL. It is importand for OPC UA Server/Client communication between two PLC’s (see: Quickstart OPC UA server configuration).

OK, I din’t understand your answer in total. But when I try to read data from my AXF5152 via OPC UA with an Notebook and via NodeRed, which IP Adress/DNS Name should I use?

Hello Fabian,
please find the answer below:
Q: But when I try to read data from my AXF5152 via OPC UA with an Notebook and via NodeRed, which IP Adress/DNS Name should I use?
A: If the DNS-Server will be not used in your network/internet, the IP address must be set to the IP address of the OPC UA server (equal to IP-Address of the PLC).
