Standardized data models turn machine signals into business-ready manufacturing information. ASTM E3012 structures battery production as discrete Unit Manufacturing Processes (UMPs), while AutomationML describes machines, equipment, relationships, and parameters in a machine-readable format. Together, they connect granular equipment data—such as power draw, cycle time, material usage, scrap, and process settings—to MES, energy management systems (EMS), ERP, and sustainability applications.
ASTM E3012 provides the process and manufacturing context; AutomationML provides structured equipment and asset information. Their combination creates a common information layer that reduces custom integration, improves traceability, and supports yield, energy, and environmental optimization.
Why Machine Data Needs a Standardized Context
Raw signals are not management information
Battery equipment generates detailed data through sensors, PLCs, historians, and control systems. However, a value such as 12.5 kW has limited meaning unless the system also knows which machine, which process step, which product batch, and which time interval it represents.
Standardized models supply that missing context. They allow an enterprise system to interpret machine-level parameters consistently rather than treating every equipment supplier’s data structure as unique.
Enterprise systems operate at a different level
ERP systems generally manage orders, materials, inventory, and production quantities. They typically do not contain the granular operational information required to understand how a specific coating run, pressing cycle, or slurry batch affected quality and resource consumption.
MES and equipment-level systems provide that detail. Standard models create the bridge between these operational layers and the higher-level enterprise view.
What ASTM E3012 Contributes
It decomposes production into Unit Manufacturing Processes
ASTM E3012 models manufacturing as connected Unit Manufacturing Processes, such as:
- Slurry mixing
- Electrode coating
- Electrode pressing or calendering
- Cell assembly
- Cell finishing
Each UMP defines a manageable process boundary. This makes it possible to associate inputs, outputs, resources, and performance measures with a specific manufacturing activity.
It organizes material, energy, and resource flows
For each UMP, the model can represent inputs such as:
- Raw materials and intermediate products
- Electrical and thermal energy
- Compressed air
- Tooling and other production resources
It can also represent outputs, including functional products, by-products, and scrap. This provides the structure needed to calculate process-level resource consumption and environmental impacts.
It connects operational data to performance analysis
A UMP gives equipment data a process meaning. Power consumption can be associated with coating or pressing, scrap can be assigned to a particular process stage, and cycle time can be compared with production output and yield.
This supports process-yield optimization, bottleneck analysis, energy monitoring, and more precise unit-level environmental datasets.
What AutomationML Contributes
It describes machines and their capabilities
AutomationML is designed to represent engineering and automation information in a structured, machine-readable way. It can describe equipment, components, relationships, interfaces, properties, and operational attributes.
For battery manufacturing, this may include the identity and structure of a coating unit, pressing system, assembly line, or associated auxiliary equipment.
It supports consistent parameter exchange
Machine parameters often differ in naming, units, hierarchy, and implementation between vendors. AutomationML can provide a common representation for these attributes, making equipment information easier to exchange between engineering tools, automation systems, and manufacturing applications.
This is particularly valuable when integrating equipment from multiple suppliers into one production line.
It enables asset self-description
Structured asset information can help downstream systems determine what an asset is, what parameters it exposes, and how it relates to other assets. When used alongside architectures such as the Asset Administration Shell (AAS), this supports more systematic asset exchange and digital-twin implementations.
How the Models Work Together
ASTM E3012 defines the process meaning
ASTM E3012 answers questions such as:
- What manufacturing process is being performed?
- What are its expected inputs and outputs?
- How should energy, materials, and scrap be accounted for?
- How does this process relate to the broader production workflow?
It acts primarily as a manufacturing-process model.
AutomationML defines the equipment representation
AutomationML answers questions such as:
- Which machine or subsystem produced the data?
- What components and interfaces does it contain?
- Which parameters and capabilities are available?
- How is the machine related to the production system?
It acts primarily as an equipment and engineering-information model.
The integration layer maps assets to processes
The practical integration task is to map AutomationML-described equipment and parameters to the relevant ASTM E3012 UMPs. For example, the power meter and compressed-air measurement of a coating machine can be associated with the coating UMP, while material consumption and scrap records are linked to the same process boundary.
That mapping allows MES, EMS, and ERP applications to consume data at the level appropriate to each use case without losing the underlying machine detail.
What This Enables Across the Enterprise
More reliable MES and ERP integration
Standardized models reduce the need for one-off interfaces between every machine and every enterprise application. The MES can collect and contextualize equipment data, while ERP receives consistent production, material, and quality information.
The result is a clearer separation of responsibilities: equipment systems provide measurements, MES provides operational context, and ERP manages enterprise-level planning and control.
Automated energy and scrap accounting
Machine-level power draw, thermal demand, compressed-air use, material consumption, and scrap quantities can be associated with specific UMPs. This supports automated reporting instead of relying on manual estimates or coarse facility-level allocations.
Energy management systems can use the same structured data to compare equipment performance and identify resource-intensive process steps.
Process-level life cycle and carbon analysis
UMP-based data can be transformed into life cycle inventory structures, including formats such as ecoSpold2 under ISO 14048. This enables more detailed life cycle assessment and product carbon footprint calculations at the subprocess level.
The quality of these calculations depends on accurate boundaries, timestamps, allocation rules, and data quality. The standards provide structure, but they do not remove the need for sound measurement and accounting methods.
Digital twins and virtual commissioning
Standardized equipment and process descriptions provide a foundation for digital twins. Real-time sensor data, historical performance logs, and physical models can be connected to the same asset and process structures.
This supports real-time monitoring, virtual commissioning, bottleneck analysis, predictive maintenance, and evaluation of production configurations before physical deployment.
Understanding the Trade-offs
Standards do not guarantee plug-and-play integration
ASTM E3012 and AutomationML improve interoperability, but they do not automatically resolve every integration issue. Organizations still need mappings between equipment tags, UMP definitions, units of measure, identifiers, timestamps, and product or batch records.
A standard creates a common language; it does not eliminate the work of defining what each organization means by a parameter or process boundary.
Data quality remains a central limitation
Poor calibration, missing timestamps, inconsistent units, and incomplete batch genealogy can undermine otherwise well-designed data models. A perfectly structured record is still unreliable if the underlying measurement is inaccurate or its operating context is missing.
Data validation, ownership, and master-data governance are therefore essential parts of the implementation.
Excessive detail can increase system complexity
Capturing every available machine parameter may create unnecessary storage, integration, and maintenance costs. The useful approach is to identify which parameters support production control, quality analysis, energy accounting, maintenance, or sustainability objectives.
The model should be detailed enough for the intended decisions, but not so broad that it becomes difficult to maintain.
Process boundaries require careful agreement
Energy and material data can be allocated to individual UMPs in different ways. For example, auxiliary systems, startup periods, cleaning operations, and shared utilities may not belong exclusively to one machine or process.
These allocation choices must be documented if the resulting yield, LCA, or carbon calculations are to be comparable and defensible.
How to Apply This to a Battery Manufacturing Integration
A practical implementation should establish the process model and equipment model together rather than treating them as separate documentation exercises.
- If your primary focus is MES and ERP integration: Define ASTM E3012 UMPs as the manufacturing context, then map AutomationML equipment identifiers and parameters to those process steps.
- If your primary focus is energy and carbon accounting: Capture electricity, thermal energy, compressed air, materials, outputs, and scrap at defined UMP boundaries with consistent units and time relationships.
- If your primary focus is yield and quality optimization: Link machine settings, cycle times, sensor measurements, product genealogy, and quality results to the relevant UMP and production batch.
- If your primary focus is digital twins and virtual commissioning: Combine AutomationML asset descriptions with real-time and historical data, then connect those assets to process-level UMP models.
- If your primary focus is scalable multi-vendor deployment: Establish common identifiers, semantic mappings, units, interfaces, and governance rules before onboarding equipment from different suppliers.
The central principle is simple: use ASTM E3012 to explain what manufacturing process the data belongs to, and AutomationML to explain which machine produced it and how that machine is structured.
