Overview of the sample analyses

The sample analyses in this section perform the following calculations in the same PI AF database:

1. Uses an expression type analysis to track the deviation from target efficiency for the asset and processes represented by the element, Ethylene.

2. Creates a template to generate a set of rollup analyses that aggregate the total power draw of all processes at a refinery. The element template from which the element for each refinery was created is called Refinery.

3. Creates event frames to capture data any time the 15-minute running-average efficiency for the element, Ethylene, drops below 90%.
