OPCDA.NET-UA based applications work with OPC DA and UA servers. The server accessed depends on the server identifier string.
For UA server access the identifier has to have the format:     UA:url

The UA server URL  has the format:   scheme://host:port/name
e.g.   http://localhost:80/Advosol/uaSim
         opc.tcp://localhost:62849/Advosol/uaSim

OPCDA.NET-UA will try to select an endpoint with the specified scheme. If no such endpoint is available then one of the available endpoints is used.
