Understand process models in PI AF

A PI Asset Framework (AF) model consists of connected elements that represent a logical model of your process. A model is itself an element, but with two additional element properties: layers and connections. Elements in the model can represent physical entities in your process, such as tanks, pipes, and process units, or logical entities, such as recipes and summary data. The model is composed of connected elements.

PI AF models can be simple, containing only a handful of elements, or they can be very complex, containing thousands of elements and measurements. The size of the model is only limited by the data available to fulfill the information requirements of an analysis on the model.
