Did you know the IP address of your XServer? Is the XServer connected to your LAN?
You need to put in the correct IP address of the XServer when TRiLOGI attempts to login to the XServer. If you leave the IP address as 127.0.0.1:9080 and TLServer is running, then TRiLOGI is actually trying to connect to the PLC via the TLServer but the PLC is not connected to the TLServer, you therefore get a no-connection error.
