The PhysicalAssetCapabilityTestSpecificationTypeis a concrete ObjectTypethat can be used directly. It is a subtype of ISA95TestSpecificationTypedefined in 6.7.3.

This ObjectTypeindicates a test for a physical asset. An instance of a PhysicalAssetCapabilityTestSpecificationType may be associated with a PhysicalAssetClassType, instances of PhysicalAssetClassPropertyType, instance of PhysicalAssetType or instances of PhysicalAssetPropertyType. This is typically used where a test is required to ensure that the Physical Asset has the necessary capability and capacity. An instance of a PhysicalAssetCapabilityTestSpecificationType may be associated with multiple instances of Physical Assets and/or multiple PhysicalAssetClassTypes.

The PhysicalAssetClassTypeis a concrete ObjectTypethat can be used directly. It is a subtype of ISA95ClassType defined in 6.7.1.

This ObjectTypeindicates a grouping of Physical Assets with similar characteristics for a definite purpose such as manufacturing operations definition, scheduling, capability and performance. An Object of PhysicalAssetClassTypemay be associated with an instance of a PhysicalAssetCapabilityTestSpecificationType. It is expected that subtypes of the PhysicalAssetClassType will be created that represent a particular class of physical asset. These subtypes will have their own set of instances of PhysicalAssetClassPropertyTypes and PhysicalAssetCapabilityTestSpecificationTypes

<PropertyName> is a placeholder for possible additional instances of PhysicalAssetClass-PropertyType. These properties can have any name but shall be referenced using the HasISA95Propertyreference and shall be of type PhysicalAssetClassPropertyTypeor a sub type of it.

Manufacturer is the Manufacturer of this PhysicalAssetClassType. The Manufacture shall be referenced using the HasISA95Attribute reference and shall be of type CompanyType or a sub type of it.

ModelNumber is the Manufacture’s ModelNumber that could be associated with this PhysicalAssetClassType. The ModelNumber is referenced using the HasISA95Attributereference type and shall be a string of type BaseDataVariableTypeor a sub type of it.

<TestSpecification> is a placeholder for any capability test specification that this PhysicalAssetClassType conforms to. These test specifications can have any name but shall be referenced using the TestedByPhysicalAssetTest Referenceand shall be of type PhysicalAssetCapabilityTestSpecificationTypeor a sub type of it

The PhysicalAssetType ObjectTypeis a concrete ObjectTypethat can be used directly. It is a subtype of ISA95ObjectTypedefined in 6.7.2. Individual instance of this PhysicalAssetTypewould have reference to PhysicalAssetClassTypethat the instance of the PhysicalAssetTypesupports. By definition of the ISA-95 model, when a Physical Asset instance or PhysicalAssetTypereferences a PhysicalAssetClassType, the addition of said reference results in the addition of all instance of PhysicalAssetClassPropertyTypedefined for the referenced PhysicalAssetClassTypeto be added to the Physical Asset instance (or PhysicalAssetTypesubtype) as instances of PhysicalAssetPropertyType. These ISA95Properties will have all the same Attributes and Properties as the corresponding PhysicalAssetClassPropertyTypeinstance.

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

This ObjectTypeindicates a specific physical asset. A physical asset may be tested by the execution of an instance of a PhysicalAssetCapabilityTestSpecificationType.

A PhysicalAssetType may be made of instances of PhysicalAssetType.

<PropertyName> is a placeholder for possible instances of PhysicalAssetPropertyType. These properties can have any name but shall be referenced using the HasISA95ClassProperty reference and shall be of type PhysicalAssetPropertyType or a subtype of it

<PhysicalAsset> is a placeholder for instance of PhysicalAssetType that this instance of PhysicalAssetType may be made up of. .These Objects can have any name but shall be referenced using the MadeUpOfPhysicalAsset reference and shall be to PhysicalAssetType or a subtype of it

PhysicalAssetClass defines the functionality of an instance of this PhysicalAssetType. .This Object shall be referenced using the DefinedByPhysicalAssetClass reference and shall be to PhysicalAssetClassType or a subtype of it

PhysicalLocationis the actual location associated with the instance of thisPhysicalAssetType

FixedAssetId is the vendor provided identification number provided with the instance of the PhysicalAssetType. For Example it maybe the serial number associated with device.

VendorId is the vendor that provides the instance of this PhysicalAssetType. This may be the same as the manufacturer associated with the related class, but it may also be different. For example a system integrator maybe the vendor that provides the PhysicalAssetType, even though it is manufactured by another company.

<TestSpecification> is a placeholder for any capability test specification that an instance of this PhysicalAssetType conforms to. These test specifications can have any name but shall be referenced using the TestedByPhysicalAssetTest Referenceand shall be of type PhysicalAssetCapabilityTestSpecificationType or a subtype of it

Equipment is the Equipment assigned to the instance of the PhysicalAssetType.

AssetAssignment – Is used to track the history of the logical Equipment to which this Physical Asset was assigned.
