Property Value

Implements

The value of a data source can be a constant value, a formula, a PI Point, a value from a relational database, etc. The value depends upon the configured data reference.

The list of available data references available on the system is provided by the PISystem.DataReferencePlugIns collection. An instance of a data reference is created by an object which is derived from the AFDataReference base class that has been registered on the PI AF Server using the RegPlugIn utility. An instance of the data reference is used to get and set values in the referenced data store.

Note
Setting this property will automatically set the IsConfigurationItem property to if the attribute was not created from a template.

If this attribute was created from an AFAttributeTemplate, then the value of this property is defined by the template's DataReferencePlugIn unless it is modified to be different from the template value. If the value is defined by a template, then changing the template's DataReferencePlugIn property will also change the value of this property of the AFAttribute.

Note
If the value of this property is defined by the template, then setting the value of this property to be the same as the template's value will reset it back to be defined by the template's value.
