The ISA-95 Purdue Model is an adaptation of the Purdue Network Model that incorporates the ISA-95 standard for integrating enterprise IT and industrial control systems. ISA-95 provides a structured framework for managing data exchange between business applications (such as ERP systems) and operational systems (such as MES and SCADA).
This model defines five key levels: Level 0 (physical processes), Level 1 (sensors and controllers), Level 2 (supervisory control systems), Level 3 (manufacturing execution), and Level 4 (enterprise planning and logistics). By aligning the Purdue Model with ISA-95, organizations can standardize communication and improve operational efficiency.
The ISA-95 Purdue Model is widely used in manufacturing and industrial environments to optimize production workflows, improve supply chain visibility, and enhance cybersecurity. With Industry 4.0 advancements, many companies are evolving this model to accommodate real-time data analytics and cloud-based automation solutions.
