ISA95ISO

ISA95ISO is not an official standalone standard. It is a shorthand used to describe the relationship and alignment between the ISA-95 family of standards and the ISO/IEC 62264 family, both of which address enterprise-control system integration in manufacturing. Together, they provide a framework for integrating enterprise systems such as ERP with manufacturing control and execution systems.

ISA-95 focuses on models, terminology, and information exchange that link business planning and logistics to plant floor operations. The standard describes a hierarchical structure that spans from process control at the shop floor up to enterprise planning and scheduling. It introduces an object model and functional models intended to standardize how data, events, and activities move between the enterprise and manufacturing layers. The goal is to facilitate interoperability, reduce integration costs, and improve visibility across operations.

ISO/IEC 62264 serves as the international counterpart to ISA-95. It adopts a similar model and terminology and provides an international framework for enterprise-control system integration. The ISO/IEC 62264 family is organized into parts that cover models and terminology, the object model, and the message model, aligning with the corresponding concepts in ISA-95. In practice, ISO 62264 is widely adopted outside North America and is often used in international procurement and manufacturing projects to ensure compatibility with ISA-95-based implementations.

Applications and impact: ISA-95/ISO 62264 guidance is commonly used to design interfaces between ERP systems, MES, SCADA, PLCs, and other manufacturing IT/OT components. It supports standardized data structures, common nomenclature, and clearer communication across systems. Challenges include aligning legacy systems with the models and keeping mappings up to date with evolving manufacturing practices, such as those emphasized by Industry 4.0.
