This Technical Report describes a reference model which comprises the abstract description for:
-
automation assets;
-
structural and operational relationships.
NOTE Examples of automation assets are machines, equipment, devices and software.
The reference model is the basis for the electronic representation of certain aspects of a plant. It covers the systems (excluding facilities) used to make products, but it does not cover raw production material, work pieces in process, nor end products.
The corresponding information which is stored in digital factory repositories represents aspects of the digital factory. This information may be used throughout the plant lifecycle. The reference model may be applied to process plants, manufacturing plants or even building automation.
