The EquipmentType is a concrete ObjectType that can be used directly. It is a subtype of ISA95ObjectType defined in 6.7.2.

This ObjectType defines a piece of equipment. Equipment may be tested by the execution of one or more tests defined by EquipmentCapabilityTestSpecificationType. Individual instance of this EquipmentType would have one or more reference(s) to EquipmentClassType(s) that the instance of the EquipmentType is defined by. A subtype of EquipmentType may also be defined for a fixed set of referenced EquipmentClassTypes. By definition of the ISA-95 model, when an Equipment instance or a sub type of EquipmentType references an EquipmentClassType, the addition of said reference results in the addition of all instances of EquipmentClassPropertyType defined for the referenced EquipmentClassType to the Equipment instance (or EquipmentType subtype) as instances of EquipmentPropertyType. These instances of EquipmentPropertyType will have all the same Attributes and Properties as the corresponding EquipmentClassPropertyType instance. This includes the same value for the BrowseName, DisplayName, Description and any other properties.

This ObjectType may be further subtyped. The subtypes create some additional restrictions. Any EquipmentClassType references that are added to a subtype of an EquipmentType cannot be removed from an instance of the subtype. If the EquipmentType subtype is updated then all instance of the EquipmentType subtype must also be updated. For example if an additional EquipmentClassType is added to the EquipmentType subtype that that EquipmentClassType must be added to all instances of the EquipmentType subtype. This allows for creating a single EquipmentType that is used for multiple EquipmentType instances.

Equipment may be made of other equipment.

<PropertyName> is a placeholder for possible additional instances of EquipmentPropertyType. These properties can have any name but shall be referenced using the HasISA95Property reference and shall be of type EquipmentPropertyType or a subtype of it

<EquipmentClass> is a placeholder for possible related EquipmentClassTypes These EquipmentClassTypes can have any name but shall be referenced using the DefinedByEquipmentClass reference and shall be an EquipmentClassType or a subtype of it

<TestSpecification> is a placeholder for any capability test specification that instances of this EquipmentType conform to. These test specifications can have any name but shall be referenced using the TestedByEquipmentTest Reference and shall be of type EquipmentCapabilityTestSpecificationType or a subtype of it

<Equipment> is a placeholder for sub instances of EquipmentType. These instances of EquipmentType can have any name but shall be referenced using the MadeUpOfEquipment reference and shall be an instance of EquipmentType or a subtype of it

EquipmentLevel is an identification of the level in the role based equipment hierarchy.

PhysicalAsset is an instance of a PhysicalAssetType that is assigned to this instance of an EquipmentType.

AssetAssignment – Is used to track the history of the physical assets assigned to this logical equipment.
