Or try to use an ethernet sniffer like wireshark.īut use a Hub Device (not a switch) for sniffing, you then are able to see both - MAC Adress and IP Adress. Step 7 tries to connect to the PLC using ISO protocol, and displays infos of your CP343-1. I think that should work, when you connect to the subnet with any ip-adress.
