The ProductionType is used to structure information given in the MachineToolType. It groups the information about the production plan and the production statistics.

The ProductionType is formally defined in Table 26.

ProductionPlan is a list of all job elements currently running and planned for execution.

If there is no job on the machine tool, there may be no ProductionJob object in the list.

In case the ProductionPlan is used as a dynamic list (i.e. ProductionJobType nodes are being added and deleted), the precondition for deleting any node is that all values of variables represent the final state of the job and are sent to all clients in active subscriptions.

ActiveProgram contains the program that is currently running on the machine tool. If the machine tool control discriminates between main and subprograms, this program shall be the main program. It is used in parallel to the ProductionPlan, so it allows for an access of the running program without browsing the jobs in the ProductionPlan.

Statistics is the object that contains statistics information related to production.
