A global standard for integrating enterprise and control systems in industrial automation and manufacturing.

ISA-95 Standard

ISA-95 is an international standard for developing automated interfaces between enterprise systems and control systems in industrial enterprises. Developed by the International Society of Automation, it provides a framework for structuring the integration of business planning and logistics systems with manufacturing operations management.

Core Hierarchy

The standard defines a five-level hierarchy:

Level 4: Business Planning & Logistics
Level 3: Manufacturing Operations Management
Level 2: Monitoring, Supervision & Control
Level 1: Sensing & Manipulating Production
Level 0: Actual Production Process

Key Components

Equipment Hierarchy Model

ISA-95 defines a consistent model for organizing industrial equipment:

Enterprise
Site
Area
Production Line
Work Cell
Unit

Information Exchange

The standard facilitates data flow between:

Implementation Benefits

Reduced integration costs through standardized interfaces
Improved operational efficiency
Enhanced data consistency across systems
Better system interoperability between vendors
Clearer communication between departments

Industry Applications

ISA-95 is widely adopted in:

Related Standards

Future Developments

The standard continues to evolve with:

Industry 4.0 integration
Cloud Computing architecture support
Industrial Internet of Things considerations
Cybersecurity framework additions

Best Practices

Start with clear scope definition
Focus on critical integration points
Implement in phases
Maintain documentation
Train personnel adequately

ISA-95 serves as a crucial foundation for modern manufacturing integration, bridging the gap between operational technology (OT) and information technology (IT) systems while supporting digital transformation initiatives.
