1.3 Attribute Description

1.3.1 ScheduledProduction

The ScheduledProduction collection contains the production time planned by the ERP system for the entire work order. These time windows represent the intended planning period during which manufacturing is to take place.

Attribute	AAS Type	Data Type	Required	Description
PlannedProductionStart	Property	xs:string (ISO 8601)	Yes	Planned production start of the work order. The timestamp is specified in ISO 8601 format, e.g. 2026-01-22T23:00:00+00:00. This date represents the earliest possible start time for manufacturing as stored in the ERP system.
PlannedProductionEnd	Property	xs:string (ISO 8601)	Yes	Planned production end of the work order. The timestamp is specified in ISO 8601 format, e.g. 2026-01-25T23:00:00+00:00. This date marks the latest point by which manufacturing should be completed.

Note: ScheduledProduction is defined as an array, allowing multiple planned time periods to be mapped (e.g. for interruptions or shift planning). At least one entry is required.

1.3.2 TakenPlaceProduction

The TakenPlaceProduction collection contains the actual production periods. This data is recorded after completion or during manufacturing and reflects the real operating times.

Attribute	AAS Type	Data Type	Required	Description
ProductionStart	Property	xs:string (ISO 8601)	No	Actual production start. The timestamp is specified in ISO 8601 format, e.g. 2026-01-22T08:00:00.000Z. This field is populated as soon as production has actually started. For planned but not yet started orders, this field remains empty.
ProductionEnd	Property	xs:string (ISO 8601)	No	Actual production end. The timestamp is specified in ISO 8601 format, e.g. 2026-01-22T16:00:00.000Z. This field is populated as soon as production has been completed. For ongoing or planned orders, this field remains empty.

Note: The entire TakenPlaceProduction collection is optional. It is typically only populated after production has started. Multiple time periods can also be specified here (e.g. for multi-day manufacturing or shift operations).

1.3.3 Details

The Details collection contains the core attributes of the work order. It identifies the order, assigns it to a location and product, and includes CO₂ footprint metrics.

Attribute	AAS Type	Data Type	Required	Description
WorkOrder	Property	xs:string	Yes	Unique identifier of the work order. The format follows the schema WO-YYYY-MM-DD-HH-MM-SS, e.g. WO-2026-02-27-15-46-51. The WorkOrder serves as the overarching reference between CommonParameter and the individual ManufacturingProcess entries. It is also used for generating the AAS ID and AAS idShort.
LocationName	Property	xs:string	No	Name of the production location, e.g. Germany, China, or a specific plant name. Used for geographic assignment of the manufacturing order and can be used for reporting and supply chain transparency.
FactoryId	Property	xs:string (UUID)	Yes	Unique identifier of the factory in UUID format, e.g. 0195f153-7b83-75d5-9d54-888c4567866d. This value identifies the specific manufacturing location within a company and enables assignment of the order to a particular plant.
OperationStatus	Property	xs:string	Yes	Current status of the work order. Possible values include planned, in_progress, and completed. This status describes the overall status at the order level, not the status of individual processes.
ProductID	Property	xs:string	No	Product identifier, e.g. PID_001. Assigns the work order to a specific end product. This field enables traceability from the manufacturing order to the produced product.
ProductFamily	Property	xs:string	No	Product family, e.g. API Test Products. Enables grouping of related products and serves for categorization in reporting and production planning.
PCFComponentName	Property	xs:string	No	Name of the PCF component (Product Carbon Footprint Component), e.g. Component A. Identifies the component for which the CO₂ footprint is calculated. This is relevant for sustainability reporting and the calculation of the product carbon footprint.
PCFComponentID	Property	xs:string (UUID)	Yes	Unique identifier of the PCF component in UUID format, e.g. 0195f153-7b83-75d5-9d54-888c4567866d. Serves as a machine-readable reference to the component for which the carbon footprint is determined.
WorkOrderCarbonFootprint	Property	xs:float	No	Total CO₂ footprint of the work order as a floating-point number, e.g. 3.086. This value represents the sum of all CO₂ emissions caused by the manufacturing of this work order (in kg CO₂e). It aggregates the individual ProcessCarbonFootprint values of all associated manufacturing processes.

Note: Each manufacturing process is created as its own SubmodelElementCollection within the submodel. The idShort of the collection corresponds to the ProcessName field from the input data (e.g. Process_PR_456_on_DMG). Any number of processes can be contained in a single submodel.

2.3 Attribute Description

2.3.1 Process Identification (ProcessName)

Attribute	AAS Type	Data Type	Required	Description
ProcessName	SubmodelElementCollection (idShort)	xs:string	Yes	Unique name of the manufacturing process. Used as the idShort of the parent SubmodelElementCollection. The recommended naming scheme is Process_{Program}_on_{Machine}, e.g. Process_PR_456_on_DMG or Process_PR_123_on_Trumpf. The ProcessName must be unique within a Bill_of_Process submodel.

2.3.2 MachineDetails

The MachineDetails collection identifies the machine, its associated program, and the current operational status of the manufacturing process. It also contains optional references to data points for integration with IoT systems.

TotalAmount	Property	xs:string	Yes	Total quantity to be manufactured in this process step, e.g. 100. Although this is a numeric quantity, the value is stored as a string in the AAS. This is the target quantity according to the work order.
ScrappedQuantity	Property	xs:string	No	Number of scrap parts produced during the manufacturing process, e.g. 0, 5. Updated during or after manufacturing and used for quality control. Default value is 0.
ProducedQuantity	Property	xs:string	No	Number of actually manufactured good parts, e.g. 0, 95. Updated during or after manufacturing. Together with ScrappedQuantity, this gives the total output. Default value is 0.
ProcessCarbonFootprint	Property	xs:float	No	CO₂ footprint of this individual manufacturing process in kg CO₂e, e.g. 0.01713. Calculated as the sum of EnergyConsumptionCarbonFootprint and MaterialConsumptionCarbonFootprint values of all energy and material consumption entries for this process.

}

4.3 Explanation of the Example

The example above models a work order WO-2026-02-27-15-46-51 comprising two sequential manufacturing processes:

1. Process_PR_456_on_DMG – Machining on a DMG machine with program PR-456:

   • Status: Ended (already completed)
   • 100 pieces planned, manufacturing took place on 02.03.2026
   • Energy consumption: electricity (0.02284 kWh) and compressed air (0.02284 m³)
   • Material consumption: 25 kg resin
   • CO₂ footprint: 0.01713 kg CO₂e

2. Process_PR_123_on_Trumpf – Machining on a Trumpf machine with program PR-123:

   • Status: planned (not yet started)
   • 90 pieces planned, manufacturing scheduled from 24.01.2026
   • Energy consumption: electricity only (0.01500 kWh)
   • No material consumption specified
   • CO₂ footprint: 0.01200 kg CO₂e

The WorkOrderCarbonFootprint of 3.086 kg CO₂e in CommonParameter aggregates the total emissions of the order including all processes and upstream contributions.
