MachineTool Equipment ToolIdentification

The Tools component of the EquipmentType is available in the AddressSpace and contains a list of all physically available tools in the machine tool.

Server

MachineTool Equipment Dynamic Tool List

In the Tools List, BaseToolType subtype nodes are added/deleted during runtime by the underlying logic of the server. The NodeVersion attribute of Tools is available and the GeneralModelChangeEvent is sent every time the node structure changes.

Server

MachineTool Notification – Errors and Alerts

All errors and warnings shown to the machine operator by the machine tool shall be sent via the MachineTool interface. This shall happen using the EventType defined by this specification fitting the best or a subtype of it. The EventNotifier shall be the Messages Object of the MonitoringType, this Object shall be present in the AddressSpace.

Server

MachineTool Production Job

The ProductionPlan Node is available in the AddressSpace. At least one ProductionJobType instance is available in the AddressSpace as a Component of the ProductionPlan Node in the MachineToolType. This node has to include all mandatory components of the ProductionJobType and may include the optional components.

Server

MachineTool Production LastTransition

The Component LastTransition of the ProductionStateMachineType and their derived types is available in all instances as specified in this CS.

Server

MachineTool Production ProductionJobStateMachineType

The ProductionJobTransitionEventType shall be sent for each transition of the ProductionJobStateMachineType.

Server

MachineTool Production ProductionProgramStateMachineType

The ProductionProgramTransitionEventType shall be sent for each transition of the ProductionProgramStateMachineType.

Server

MachineTool Production ProductionPartStateMachineType

The ProductionPartTransitionEventType shall be sent for each transition of the ProductionPartStateMachineType.

Server

MachineTool Production InterruptionConditionType

For all interruptions of the production job where a reason is known to the machine tool, the InterruptionConditionType shall be sent. It is sent by the instance node of the ProductionJobType where the interruption occurred. The Properties ConditionClassId and ConditionClassName are set to the BaseConditionClassType subtype fitting the best to the reason for the interruption.

Server

MachineTool Equipment ToolLife

The Component ToolLife has to be present for every tool. Within ToolLife, at least one ToolLifeEntry has to be provided.

Server

MachineTool PrognosisType

The Notification component of the MachineToolType shall contain the Prognoses object.

The PrognosisType 8.6.4 is the most basic prognosis type and the supertype to more specific prognosis types. At least one of the PrognosisType subtypes defined in this specification is required for the Prognoses Facet. If the respective prognosis can be given, it shall be referenced as a component by the Prognoses Object in the Notification component of the MachineToolType.

If the PrognosisType subtype refers to a node in the AddressSpace via a NodeId and the respective node exists in the AddressSpace, the respective Component of the PrognosisType shall be present.

Server

MachineTool Prognoses Dynamic List

In the Prognoses List, PrognosisType nodes are added/deleted during runtime by the underlying logic of the server. The NodeVersion attribute of Prognoses is available and the GeneralModelChangeEvent is sent every time the node structure changes.

Server

MachineTool Production Dynamic Job List

The ProductionPlan Node is available in the AddressSpace. In the ProductionPlan, ProductionJobType nodes are added/deleted during runtime by the underlying logic of the server. The NodeVersion attribute of the ProductionPlan is available and the GeneralModelChangeEvent is sent every time the node structure changes.

Server

MachineTool Production Job Available

Either the CU Machine Tool Production Job or the CU MachineTool Production Dynamic Job List shall be supported.

Server

MachineTool Monitor Items Min

Supports to monitor all exposed instances of Variables and Objects that have the EventNotifier set, that are defined in the MachineTool specification in a Subscription. The server should support at least 20 MonitoredItems for at least one Subscription and one Session. The server may set the revisedPublishingInterval as appropriate.
