The International Society of Automation (ISA) has, in a significant development for industrial automation and digital manufacturing environments, released the 2025 edition of the ANSI/ISA-95.00.01 (IEC 62264-1 Mod) standard. The latest revision marks a pivotal enhancement to the ISA-95 series, reinforcing a common language and set of models essential for bridging the historically siloed domains of IT and operational technology (OT). The update reflects emerging industry needs, evolving best practices, and the increasingly complex interplay between enterprise-level operations and shop floor execution.
Titled ‘Enterprise-Control System Integration – Part 1: Models and Terminology,’ the ANSI/ISA-95.00.01-2025, also known as ISA-95 Part 1, summarizes the scope of the manufacturing operations and control domain, discusses how physical assets of a manufacturing enterprise are organized, lists the functions associated with the interface between control functions and enterprise functions and describes the information shared among these functions.
The ISA95 standards committee, which develops the ISA-95 series, sought to account for a shifting industrial landscape when authoring the most recent revisions. Also known as ANSI/ISA-95 or IEC 62264, it is an international set of standards aimed at integrating logistics systems with manufacturing control systems. It organizes technology and business processes into layers defined by activities taking place, and it outlines how an enterprise can set up an interface to communicate among these layers.
The ISA-95 standards framework is widely accepted as essential to modern manufacturing. It relies on the well-known Purdue Reference Model for computer-integrated manufacturing to describe network segmentation in industrial control systems. It establishes an architecture based on the Purdue model that enterprises can apply regardless of the technology used. This equipment hierarchy model can also be applied across discrete, continuous, and logistics industries.
The update to the 2010 version of ISA-95 Part 1 includes changes to reflect specific functions in the enterprise, highlight the boundary between enterprise and manufacturing and control domains, and introduce consistency with other details in the standard. As the world grows more digitized, the ANSI/ISA-95.00.01-2025 update reflects the ongoing need for an integration standard.
“Trends in digital transformation have driven the emergence of increasingly modular architectures across business and manufacturing operations,” Christian Monchinski, chair of the ISA95 standards committee, said in a media statement. “These architectures consist of containerized workloads that can scale dynamically and operate on-premise, in the cloud, or in hybrid environments. Equally important is the shift toward data-centric architectures, where system data is enriched through metadata formed from standards-based contextualization.”
Monchinski added that the updated ISA-95 Part 1 reaffirms the importance of standardized integration interfaces across these systems. It also reinforces ISA-95’s critical role in providing shared ontologies and semantic models for representing manufacturing operations information.
He also noted that the ANSI/ISA-95.00.01-2025 release equips the global industrial community with the vocabulary and structural foundation needed to design connected, intelligent, and agile manufacturing systems.
Last September, the ISA announced a new certificate program designed to provide an overview of the ISA-95/IEC 62264 standards framework for integrating enterprise and control systems in manufacturing. The program delivers an overview of the ISA-95/IEC 62264 standards framework, as well as the knowledge needed to define business activities and the flow of information between flexible shop-floor execution systems and enterprise planning (ERP) systems.
