  • 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 Nrio 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 the Point Manager).

  • Conversion

  • Read Value

    (read only) Last value read, using device facets.
