IEC 62264 is an international standard from the International Electrotechnical Commission that specifies models, terminology, and interface structures for integrating enterprise systems with manufacturing operations and control systems.
The standard is closely aligned with the ISA‑95 series and is effectively its IEC adoption. It formalizes how information should be organized and exchanged between business-level applications (such as ERP and supply chain systems) and manufacturing-level applications (such as MES, LIMS, and SCADA).
IEC 62264 defines, among other things:
- Functional hierarchies for enterprise and manufacturing operations
- Object models for equipment, materials, personnel, and processes
- Activity and information models for production, quality, maintenance, and inventory operations
- Standard categories for interfaces between enterprise and control systems
In practice, organizations use IEC 62264 as a reference for structuring data models and integration points between IT systems (for example, ERP) and operational technology systems (for example, MES and plant-floor control systems).
