PI point data references

A PI point data reference is a reference from an attribute to a PI point. The value of the data reference attribute can be the same as the point value, or it can be the result of a calculation based on point values. You can create a PI point data reference for:

• An element attribute or an element attribute template

• A transfer attribute or a transfer attribute template

• An event frame attribute or an event frame attribute template

A PI point data reference for an attribute template has additional features. When you create a PI point data reference in an attribute template, you can:

• Automatically create tags referenced by attributes based on the template.

• Create a naming scheme for attributes based on the template so that attributes built from it have unique names that conform to a consistent structure.

To reference the PI point, you use a direct or an indirect reference. There are two quick methods to create a direct reference, whereas you need to use the PI Point Data Reference window to create a more complex direct reference or an indirect reference.
