Status
Summary Indicates whether the external interface component
represented by the UpgradeInfo object was preserved or
deleted during the external interface upgrade. It also
indicates whether any other modifictions were made as a
result of the upgrade (for example, the component was
moved).
• If an external interface component is preserved, the new
component will automatically have its properties set to
match the old component, and the component will be
bound into any connections of which the old component
was a member.
• If an external interface component is deleted, all
connection information and properties set for that
component will be erased. If the component is a
configuration property, its value will also be erased. Use
the Reason property to find out why a component was
preserved or removed from the new interface.
You can use the Class and FromIndex properties to
determine the interface component to which the Status
property applies.
If the component is a configuration property contained by a
LonMarkObject or NetworkVariable, you can use the
FromOwnerIndex property to identify the LonMarkObject or
NetworkVariable object.
Availability Local, full, and lightweight clients.
