Hi,

I Am working on a project where the OPC UA Server (Phoenix contact AXC 1050 PLC) is connected to a Sierra RV50 router with a M2M Sim-Card (Router 1).
The OPC UA Client is a laptop with TIA Portal WinCC professional on a office-network (Router 2).


So I know that I Should put the IP “opc.tcp://name:Port” of the PLC (OPC UA Server) in the “OPC UA Discovery URL” in TIA Portal Scada (OPC UA Client.)
But this won’t work because the PLC is on another network. 

I found something that it should be possible to connect the 2 networks with a VPN-Tunnel. 
But now my question is, 

Is it possible to send and receive data over a VPN Tunnel with OPC UA?

Hope to receive a reaction.
Thanks in advance!

OPC UA is works over any network that provides the ability to route messages in both directions.

The most common transport mappings rely on TCP with sockets initiated by a client.
