How to configuring OPC server and Trend server on same machine?

Hi,

I am quite new to Freelance and working on a project with Freelance 2013 on Windows 7. I need to send some signals to third parties such as Wonderware Historian.So I am using OPC server. Also, I need a Trend server too.

I configured both servers and assigned IDs.I changed the setting (resource ID) in OPC Tunnel, restarted the service, and the servers are working fine individually.I have only one OPC Tunnel which is set for OPC server or Trend server, so how I can run both OPC and Trend servers on one machine?

Thanks
