with the functions described in this chapter. 
3.2  About This Chapter 
This chapter describes the syntax of each of the functions you can use to read and write to 
the values of the data points in your network. It also includes code samples written in 
Microsoft Visual Basic .NET that may be useful when designing applications that use these 
functions. 
NOTE: You can use the Data Point functions to read and write to the values of your data 
points. You must create data points and add them to the Data Server before using these 
functions. You can create NVL data points with LONMAKER. You can create NVC data points 
with the i.LON 100 Configuration Software, or with the SOAP interface. 
For more information on the using the SOAP interface to create data points, see Chapter 5, 
Data Server. You should review Chapter 4, i.LON 100 Applications and the SOAP/XML 
Interface, before using the SOAP interface to create data points. For more information on the 
i.LON 100 Configuration Software, see the i.LON 100 Internet Server User’s Guide.
