Hi,

We have configured 2 SCADA server. Both are having different public IP. when both servers are up thin client connections are distributed among two servers. but when primary server goes down we are not able to connect new thin client connection with the link of primary server public IP even if backup server is up. we need to connect to the secondary server's public IP manually.

So is there any way to have a single thin client link which can manage thin client connection even if any one server is down?

Not possible with VTScada.

You would likely need a DNS service which monitors the servers and switches over DNS Records dynamically. That'd still have a downtime.

You could also play with proxy servers.

How to configure DNS for VTSCADA sever ? and what do you mean by proxy server.
