2.4 Writing SOAP Applications
The majority of the SOAP functions and XML files described in this document will be useful
to those who plan to use the SOAP/XML interface to configure the various applications of the
i. LON 100. To begin learning about the SOAP functions and XML files you can use to do so,
see Chapter 4, i.LON 100 Applications and the SOAP/XML Interface.
However, the SOAP/XML interface for the i. LON 100 also includes functions which allow you
to write applications to monitor and control the data points you have created for your control
network with L
ON M AKER and the i. LON 100 Configuration Software. Applications like these
may be useful to anyone using the i. LON 100, including those who will only be using
L ON M AKER and the i. LON 100 Configuration Software to configure the i. LON 100’s
applications. For more information on these functions, see Chapter 3, Monitoring and
Controlling Data Points with the SOAP/XML Interface.
