7.4 DataTypes

7.4.1 ISA95EquipmentElementLevelEnum

This DataType is an enumeration that defines the equipment element levels defined in ISA-95. Its values are defined in a below table.

Table 36 – ISA95EquipmentElementLevelEnum Values
ValueDescription
ENTERPRISE_0An enterprise is a collection of sites and areas and represents the top level of a role based equipment hierarchy.
SITE_1A site is a physical, geographical, or logical grouping determined by the enterprise. It may contain areas, production lines, process cells, and production units.
AREA_2An area is a physical, geographical, or logical grouping determined by the site. It may contain work centres such as process cells, production units, production lines, and storage zones.
PROCESSCELL_3Process cells are the low level of equipment typically scheduled by the Level 4 and Level 3 functions for batch manufacturing processes. The definitions for process cells are contained in IEC 61512-1.
UNIT_4Units are low level of equipment typically scheduled by the Level 4 and Level 3 functions for batch manufacturing processes and continuous manufacturing processes. The definition of the unit for batch manufacturing processes is contained in IEC 61512-1.
PRODUCTIONLINE_5Production lines are low levels of equipment typically scheduled by the Level 4 or Level 3 functions for discrete manufacturing processes.
WORKCELL_6Work cells are low levels of equipment typically scheduled by the Level 4 or Level 3 functions for discrete manufacturing processes.
PRODUCTIONUINT_7Production units are the lowest level of equipment typically scheduled by the Level 4 or Level 3 functions for continuous manufacturing processes.
STORAGEZONE_8Storage zones are low level of material movement equipment typically scheduled by the Level 4 and Level 3 functions for discrete, batch and continuous manufacturing processes.
STORAGEUNIT_9Storage units are low level of material movement equipment typically scheduled by the Level 4 and Level 3 functions for discrete, batch and continuous manufacturing processes.
WORKCENTER_10Work centres are typically the grouping of equipment scheduled by the Level 4 or Level 3 functions.
WORKUNIT_11A work unit is any element of the equipment hierarchy under a work centre. Work units are the lowest form of elements in an equipment hierarchy that are typically scheduled by Level 3 functions.
EQUIPMENTMODULE_12An equipment module entity is an engineered subdivision of a process cell, a unit, or another equipment module. The definition of the equipment module is contained in IEC 61512-1.
CONTROLMODULE_13A control module entity is an engineered subdivision of a process cell, a unit, an equipment module, or another control module. The definition of the equipment module is contained in IEC 61512-1.
OTHER_14The types of work centres may be extended when required for application specific role based equipment hierarchies where the defined types do not apply. In that case, the equipment element level shall be specified as this value, and actual value that identifies the level shall be specified by OtherValue Property of ISAHierarchyScopeType defined in 7.4.1. When a new type is added it shall maintain the same relationship within the hierarchy as the defined work centre types (within an area and contains work units).
