Data Reference

Attributes allow elements to reference calculations and PI tags through a data reference. Data references are plug-ins to the PI Analysis Framework and allow data to be populated from automated field data collection and business systems. You can configure one data reference for each Attribute in an element. When the Element is then used in a Model analysis, the analysis receives the value through the data reference. An analysis can send output results through a data reference, as well as receive values as inputs. If an Attribute does not use a data reference, then the value read is the last value written.
