This section introduces the “OPC UA Information Model for Machine Tools”.
This Information Model provides the necessary ObjectTypes to model a machine tool interface in a structure as illustrated in
Figure 6. There are ObjectTypes that are used to identify the machine tool (MachineToolIdentificationType), to monitor the machine tool(Monitoring Type), to manage the production(Production Type) on the machine tool, to handle the Equipment of the machine tool (EquipmentType) and to give notification on the status of the machine tool(NotificationType).
The ObjectTypehierarchy of this Companion Specification is shown within the Figures 7-12. Objects from external specifications are positioned within greyish-green boxes.
