I forgot to mention one important thing. For testing purposes, you have to set your PC network adapter IP address to match IP address set in Connect function (in my example 192.168.142.130/24).
Make sure your firewall is not blocking the traffic.
When you modify any parameters related to connection, restart PLC (menu online/download and restart PLC).
