Using Ethernet Communication,

I think you misunderstand the question,
my PLC having an Ethernet/IP protocol,
TS4 device got the Ethernet Port ( written on the TS4 unit ),

How to communicate the PLC with TS4 using Ethernet/IP protocol?

Default base socket on TS4 is 2000
You can configure ports for “TCP Sockets” and then connect to it on IP of the TS port 2001 or 2101(for RAW socket, port 1)

Thank you,
