Process Classes (Processes)

A process class is a group of units. Each unit in the class has the same processing capabilities or performs the same function. For example, a plant may have five blenders, each of which has the same processing capability. The only difference between the blenders might be capacity and blending efficiency. All five blenders can therefore be identified by one process class.

Some units have no processing capabilities but perform the same function. Examples of these units are bulk ingredient storage tanks, hold tanks, filling stations, and manual add stations.

Each process can have a common set of attributes, which further define the capabilities of each unit in the class. Unit attributes are used by the AVEVA Batch Management System to verify that the units in the train match the equipment requirements defined by the recipe.
