5.1.1 DP_NVL.XML
The DP_NVL.XML file is created automatically the first time the
i.
LON 100 boots. It will
contain an <NVL> element for each static NV on the device. The properties contained within
these elements define the configuration of an NVL data point, and are described later in this
chapter. Each time you use L
ON
M
AKER
to create a dynamic network variable for the
i.
LON
100, an <NVL> element for the associated data point will be added to this file.
You can modify a data point's configuration after it has been added to the
i.
LON 100 by
manually editing this XML file, or by using the DataServerSet function. The sections
following the example XML files provide guidelines and instructions to follow when doing so.
The following represents a sample DP_NVL.XML file for an
i.
LON 100 with four NVL data
points.
