For a device class file, you need the network variable index for each network
variable. The index is the first value following the network variable name:
• VAR nviValue 0 0 0 0 …
• VAR nvoValueFb 2 0 0 0 …
• VAR nvoPower 5 0 0 0 …
Thus, nviValue has index 0, nvoValueFb has index 2, and nvoPower has index
5. And so, you can fill in these values within <attributes> element in the device
class file:
<attributes>
<attribute name="state">
<nvs>
<nv index="0" direction="input" />
<nv index="2" direction="output" />
</nvs>
</attribute>
<attribute name="power">
<nvs>
<nv index="5" direction="output" />
</nvs>
</attribute>
</attributes>
Likewise, you can you can fill in these values within <nvs> element in the device
class file:
<nvs>
<nv index="0" direction="input" size="3">
<byte index="0" length="1">
<attribute name="state" enum="true">
...
</attribute>
</byte>
</nv>
<nv index="2" direction="output">
