Two IP connect to One OPC-UA Server|OPC UA Standard|Forum|OPC Foundation

Hi all,

I’m new here cause for the first time i’m using OPC UA to connect with machines.

It all seems pritty simple but i’ve one problem:
I have two machines:
Machine1: IP-address-1 – hostname1
Machine2: IP-address-2 – hostname2

The problem is that UAExpert and PLC connecting me always to Machine1 OPC-UA server, no matter wchich connection parameters i enter:

opc.tcp://IP-address-1:Port -> connected to Machine1 OPC UA Server

opc.tcp://hostname1:Port -> connected to Machine1 OPC UA Server

opc.tcp://IP-address-2:Port -> connected to Machine1 OPC UA Server

opc.tcp://hostname2:Port -> connected to Machine1 OPC UA Server

I’d ping two IP’s and in network they have correct/different hostnames.

Can you write me what could be a reason this happen? Maybe some network settings?

I’ve matched hostnames to ip addresses in C:\WINDOWS\System32\drivers\etc\hosts file but it didn’t change anything.

Thanks in advance.

Best regards

Pawel
