Value Property (PointAttribute object)



The Value property of the PointAttribute object is a Variant that is used to view or modify the value associated with a particular PointAttribute. It can represent the value of an attribute for a particular point or the default value for newly created points of a particular point class. The value cannot be successfully set until the ReadOnly property of its parent collection is set to FALSE.




The object placeholder is an object expression that evaluates to a PointAttribute object.



The Value property is a variant. When assigning new values to the property the PI-SDK will attempt to coerce the passed data type to the type of the attribute. When modifying attribute values, the containing collection’s ReadOnly property should be set to FALSE but should be returned to TRUE after the desired modifications are made to reduce the risk of inadvertent modifications.
