Instruction Manual
5.1  Data Server XML Files 
The /root/config/software/dataserver directory of your i.LON 100 contains several XML files 
that will store the configuration of the data points in your Data Server. Table 7 describes 
these XML files. 
Table 7  Data Server XML Files 
File Name  Description 
DP_NVL.XML  When a local NV for the i.LON 100 is created using LONMAKER, a 
corresponding NVL data point is automatically added to the Data Server. 
Its configuration can then be modified using the SOAP interface or the 
i.LON 100 Configuration Software, and it can be referenced from the i.LON 
100 applications. 
The DP_NVL.XML file stores the configurations of the NVL data points in 
your Data Server. This file contains an entry for each static, dynamically 
created data point that has been added to the Data Server. 
NOTE: NVL data point must always be created using LONMAKER. 
DP_NVC.XML  This file contains an entry for each NVC data point that has been added to 
the Data Server. An NVC data point represents a network variable that 
maintains a constant value. 
These data points can be created with the DataServerSet function, which is 
described later in this chapter, or with the i.LON 100 Configuration 
Software. 
The following sections provide examples of each of these files. Guidelines and instructions to 
follow when modifying these files, manually or with the SOAP interface, follow the examples.
