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 L ON M AKER , 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 L ON M AKER.
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.
