The international standard ANSI/ISA-95 (S95), was introduced in 1995 to resolve the issues encountered in the integration of enterprise and control systems. The standard provides a common understanding of terminology, information exchange, workflows, best practices, models and activities and functions. ISA-95 is relevant to all manufacturing and processing industries, and the principles can be applied to batch, continuous, discrete or repetitive processes using different technologies.
The ANSI/ISA-95 (S95) standard consists of models and terminology, used to establish which information can be transferred between the sales and finance ERP systems and the production, maintenance and quality MES systems. This information is organised in models, which form the basis for the design of interfaces between the ERP and MES systems.
With extensive experience in the design and implementation of MES systems following the ANSI/ISA-95 (S95) standard, ITS offers advice and consultancy to help companies get the most from the standard. We also have a team of engineers, experienced in the successful integration of enterprise ERP systems with MES and control systems.
The ANSI/ISA-95 (S95) standard consists of five main parts:
ISA-95.01 Models and Terminology
Part 1 includes the models and terminology, which are used to determine which information can be exchanged between the enterprise and control systems.
ISA-95.02 Object Model Attributes
Part 2 introduces the object model attributes which are used for the data exchange between the systems and the foundation for relational database design.
ISA-95.03 Models of Manufacturing Operations Management
Part 3 defines activity models and data flows that enable enterprise-level system integration. The modeled activities in Part 3 are consistent with the Part 1 object models and the Level 3 (Manufacturing Operations and Control) definitions.
ISA-95.04 Object Models and Attributes
Part 4 is in development.
ISA-95.05 Business-to-Manufacturing Transactions
Part 5 focuses on business exchanges which enable cross-application information collection, retrieval, transfer and storage, in support of enterprise-level system integration. It covers: Personnel Model, Equipment Model, Maintenance Model, Material Model, Process Segment Model, Production Capability Model, Product Definition Model, Production Schedule Model, and Production Performance Model.
Companies following the ISA-95 standard benefit from a common understanding, which enables employees responsible for different types of systems to communicate effectively with one another. The standard increases simplicity, provides best practice across the site and reduces risk and misunderstanding, which in turn reduces the integration process and cost.
