Substituted Property (IPIValueAttribute interface)


The Substituted property of IPIValueAttribute is a read-only Boolean property of the PIValue object. The property is true if the PIValue has been changed (edited) on the PI server.



The object placeholder is an object expression that evaluates to an IPIValueAttribute object.


This is a read-only property. It is populated when you retrieve a PIValue from a PI server.  When an application creates a new PIValue this property is false.
