PI Asset Framework (PI AF) 2010 is an integral part of the PI Server 2010. It allows you to build an asset model of the physical objects in your process and associate asset properties to your data. This asset model becomes a middle layer or “directory” allowing you to find and consume the information you need quickly and effortlessly. This assent centric model is extremely useful on CBM (Condition Based Maintenance) projects, as helps users to easily identify assets attributes and relate them on complex calculations.
