Annotations Property (IPIValueAttribute interface)

             

The Annotations property of IPIValueAttribute is a read/write property of the PIValue object. When used as a "get", the property returns a Variant containing the annotation of the corresponding PIValue object. If there is no annotation or annotations were not requested at the time of data retrieval, the Variant will be empty (VT_EMPTY).

Syntax

object.Annotations

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

Remarks

This is a read/write property. It is populated when you retrieve a PIValue from a PI server or may be used to set an annotation in a PIValue that could then be sent to the PI server.
