Greetings,

For your setup, since you seem to be trying to communicate over the internet, a VPN connection (or at least Port forwarding) would be required since Scada and the PLC are behind NAT.

You can opt for RMS VPN: RMS VPN Hubs - Teltonika Networks Wiki
Or any other VPN that we have to offer here: VPN Configuration Examples - Teltonika Networks Wiki
