The role class “StorageZone” should be used defining the role based equipment hierarchy defined in IEC 62264-1:2013 at the storage zone level: The definition of an “StorageZone” is given in IEC 62264-1: 2013, 5.3.9: “Storage zones and storage units are the lowest level of material movement equipment typically scheduled by the Level 4 and Level 3 functions for discrete, batch and continuous manufacturing processes. A storage zone is a type of work center and a storage unit is a type of work unit that is organized as elements within an area. These are the lower-level elements of an equipment hierarchy used in material storage and movement activities. A storage zone typically has the capability needed for the receipt, storage, retrieval, movement and shipment of materials. This may include the movement of materials from one work center to another work center within or between enterprises.”

The StorageZone is formally defined in Table 99.
