Depending on the item selected, the default point type will be either writable or read-only, as follows:
-
nvi (read-only, that is NumericPoint, EnumPoint, BooleanPoint, or StringPoint)
-
nvo (writable, that is NumericWritable, EnumWritable, BooleanWritable, or StringWritable)
-
nci (read-only, that is NumericPoint, EnumPoint, BooleanPoint, or StringPoint)
Point type selections for local nvis and ncis are limited to read-only types (meant to be written externally, that is, outside the station). In the case of local nvos, only writable point types
have any practical application--as only the station is capable of writing to its own nvos. Note that this is “the reverse”
of the default point type selections when creating other Lon proxy points.
However, you can select another data category. See Lon proxy point type selection.
