Learn about PI AF models

You can use PI Builder to create, retrieve, edit, and delete PI AF models with Microsoft Excel. A PI 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.
