The ObjectType is formally defined in Table 12. Note that the transitions do not expose causes as the StateMachine is not used on an individual Object exposing its state, but just as meta data for values.
The component Variables of the ISA95JobOrderReceiverObjectType have additional Attributes defined in Table 14.

JobOrderList - Defines a read-only list of job order information available from the server. The information returned is defined by the server and may be a complete copy of a received job order or may be just the IDs and the state of the job orders. If there are no job orders available from the server, then this may be null.
MaxDownloadableJobOrders - Defines the maximum number of job orders that can be managed at the same time. As all managed job orders are accessible in the JobOrderList, it restricts the length of that array. Max of UInt16 indicates, that there is no limit.
WorkMaster - Defines a read-only set of work master IDs that may be specified in a job order, and the read-only set of parameters that may be specified for a specific work master. If there are no restrictions on what work master IDs can be sent with a job order, then this may be null.
Recipes associated with the job order are identified using the WorkMasterID. The ID in the ISA95WorkMasterDataType is an identification of the Work Master and can be internal identifications, NodeIds, web links, or a client and server agreed to format.
MaterialClassID - Defines a read-only set of Material Classes IDs that may be specified in a job order. If there are no restrictions on what Material Classes IDs can be sent with a job order, then this may be null.
MaterialDefinitionID - Defines a read-only set of Material Definition IDs that may be specified in a job order. If there are no restrictions on what Material Definition IDs can be sent with a job order, then this may be null.
EquipmentID - Defines a read-only set of Equipment Class IDs and Equipment IDs that may be specified in a job order. If there are no restrictions on what Equipment IDs can be sent with a job order, then this may be null.
PhysicalAssetID - Defines a read-only set of Physical Asset Class IDs and Physical Asset IDs that may be specified in a job order. If there are no restrictions on what Physical Asset IDs can be sent with a job order, then this may be null.
PersonnelID - Defines a read-only set of Personnel IDs and Person IDs that may be specified in a job order. If there are no restrictions on what Personnel IDs can be sent with a job order, then this may be null.
The ObjectType inherits from the 0:FiniteStateMachineType to provide the StateMachine all job orders managed by the instances of the ObjectType support. The mandatory CurrentState inherited shall always return a BAD StatusCode, as the Object only provides the meta data of the states of the job orders provided in the JobOrderList. The ObjectType may provide be subtyped to provide SubStateMachines for specific states and also the AvailableStates and AvailableTransitionsVariables may be provided to restrict the usage of the StateMachine.
