5.1.2 DP_NVC.XML
The DP_NVC.XML file contains a list of elements, one for each NVC data point that
you have added to the Data Server. An NVC data point represents an
i. LON 100 system
variable that maintains a constant value.
Each element defines the configuration of an associated NVC data point. The properties that
must be defined within each element define the configuration of an NVC data point,
and are described later in this chapter.
The following represents a sample DP_NVC.XML file for an
i. LON 100 with two NVC data
points. You can add NVC data points to the Data Server using the DataServerSet function,
or by manually editing the XML file. The sections following the example XML files provide
instructions and guidelines to follow when doing so.
