5.2.1.5.2 DataServerWrite and the Web Binder Application

You can use the Web Binder application to create connections that allow direct data
exchange over a TCP/IP network between two

i

.LON 100s, or between an

i

.LON 100 and any

Web server that can communicate via SOAP messaging such as Apache or IIS. You can

configure the Web Binder using the built-in Web pages included with the

i

.LON 100, as

described in Chapter 1 of the

i

.LON 100 Internet Server User’s Guide: Using the i.LON 100

Web Pages to Configure Applications and to Monitor and Control Data Points document.

Once the WebBinder has been configured, the

i

.LON 100 will send a DataServerWrite SOAP

message for each update of a source data point to the destination server. Thus, to create an

application on the Web server to receive WebBinder updates from the

i

.LON 100, you only

need to implement the DataServerWrite method. You should note that an application which

can receive the DataServerWrite message from the

i

.LON 100 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 find an example if such a server-side WebBinder application on the

i.

LON 100 area
