C.3 Example interpretation for SEMI E10

The MachineryItemState OutOfService and the MachineryOperationMode Processing can be interpreted as SEMI E10 “Unscheduled Downtime”.

The MachineryItemState NotExecuting and the MachineryOperationMode Setup can be interpreted as SEMI E10 “Engineering time”.

The MachineryItemState NotExecuting and the MachineryOperationMode Processing can be interpreted as SEMI E10 “Standby time”.

The MachineryItemState Executing and the MachineryOperationMode Processing can be interpreted as SEMI E10 “Productive time”.

In this example, the availability of the Machine is calculated according to ISO 22400. For this purpose, the Actual Production Time (APT) and Planned Busy Time (PBT) are required. The APT can be derived from the combination of the MachineryItemState "Executing" and the MachineryOperationMode "Processing". Alternatively, the APT can also be derived from the Semi E10 time "Productive time". The PBT is usually not known to the Machine and is accordingly not provided by this specification.
