Under the project tree Interfaces->Ethernet->Protocols, right click and you have to add new object as Modbus TCP/IP server. From there you can make your
required configuration and addresses of variables which have to communicate over the network. Use %MB0.x for bool and %MW0.x for words for addressing.
in addition to this there are few old threads which can be useful to you.
