The following sections specify the Facets and Profiles available for Servers that implement the Machine Tools companion specification. Each section defines and describes a Facet or Profile.
Table 106 defines a Profile that describes the minimum required content and address space functionality any MachineTool server shall at least provide. Concerning Stacklights and Channels, it is expected that a server models these elements if they are available on the machine tool.

The Production Plan Server Facet uses the ProductionPlan as a dynamic list. Jobs can be added and deleted to mirror the job list on the machine tool more closely. The OPC UA server can show jobs scheduled for future production and jobs that are finished in this list along with one or multiple active jobs. The ProductionJobStateMachine enables OPC UA Clients to distinguish between these states.
