As shown in the property sheet view (Figure 11), each Ndio point has the following properties in its proxy extension (Proxy Ext):
Status
(read only) Status of the proxy extension.
Fault Cause
(read only) If point has fault status, provides text description why.
Enabled
Either true (default) or false. While set to false, the point’s status becomes disabled and Ndio polling is suspended.
Device Facets
(read only) Native facets used in proxy read or writes (Parent point’s facets are used in point status display, and are available for edit in Add and Edit dialogs in Point Manager).
Conversion
Specifies the conversion used between the “read value” (in Device Facets) and the parent point’s output (in selected point facets). For details see Conversion types in Ndio proxy points.
Tuning
Assigned tuning policy, in Ndio is typically “Default Policy.”
Read Value
(read only) Last value read, using device facets.
Write Value
(read only) Applies if writable point only. Last value written, using device facets.
Poll Frequency
Assigned poll frequency group, either Slow, Normal (default), or Fast.
Point Type
(read only) Ndio point type, such as “Resistive Input,” “Boolean Output,” and so on.
Address
Point’s I/O terminal address for its hardware type (UI, AO, DO), automatically found if added from Learn Mode discover. If address is set to out of range (relative to I/O board) or is a duplicate address (same address as same hardware type, same board), the point has a fault status.
Synced
(read only) Either false or true. Reflects if the Ndio processor has synced with the current software configuration of the I/O point. Should always be true.
Raw
(read only) Raw 12-bit unsigned integer value returned by the Ndio processor.
