• An LNS uplink binding is a connection between a SmartServer and an LNS Server. LNS uplink
bindings replace the LNS uplink feature that was used in the e3 release for data point connections
between an i.LON 100 e3 server and an LNS Server.
• An enterprise binding is a connection between a SmartServer and a Webbinder Target Server.
Enterprise bindings are useful for sending a data log, an alarm log, an event scheduler log, or any
user-defined file to a central enterprise system.
If you are creating peer-to-peer bindings, LNS uplink bindings, or enterprise bindings, you must first
add the host device (remote SmartServer, LNS server, or Webbinder Target Server) to the LAN on
which your local SmartServer resides using the SmartServer Web interface. See Chapter 3 of the
i.LON SmartServer 2.0 User’s Guide for how to add host devices to the LAN.
Note: An application that can receive a Write request from the SmartServer differs from an application
that would use all of the other methods described in this manual in that it must be a “server-side”
application rather than a client application.
You can use the SOAP interface to perform the following functions on a Web connection.
Function Description
List List the name of the Web connections that you have added to the
Data Server.
Get Retrieve the configuration of a Web connection.
Set Create a Web connection and add it to the Data Server, or modify
the configuration of an existing Web connection.
Delete Remove a Web connection from the Data Server.
4.4.1 Using the List Function on a Web Connection
You can use the List function to retrieve a list of the source data points on the local SmartServer
representing the Web connection that have been added to the Data Server. The List function takes an
element that has an xSelect statement querying items of a Dp_Ref type as its input, as
shown in the example below. The List function returns an element for each source data point
in the Web connections on the local SmartServer.
