A set of server URL's can be defined in web.config AppSettings sections and one of these servers is selected in the above DropDownList control.
If the URL is changed to access another OPC Server than Advosol.SimDAServer.1 (local, remote or through an XML gateway), then also the item names must be adapted in the code.
