50 LonBridge Device Class File
Figure 5. The Scales Tab for the SNVT_power Type
For a LonBridge application, you might want to show the power as whole units,
so you can include a scale attribute of 10 to display whole values.
Thus, the <nv> element for the
power attribute within the device class file
includes the following information:
<nv index="?" direction="output" size="2">
<byte index="0">
<attribute name="power" scale="10" length="2" />
</byte>
</nv>
The definition still lacks the network variable index for the nvoPower network
variable; see
Browse the XIF File to Determine Indices on page 56 to determine
the index.
Determining the Attributes for nviValue and
nvoValueFb
For SNVT_switch_2, the Resource Editor displays the attribute information
shown in Figure 6 on page 51.
