ISA-95.02 Object Model Attributes

Part 2 of ISA-95: “Object Model Attributes” (ANSI/ISA-95.00.02-2010 (IEC 62264-2 Mod))

This Part 2 standard further defines formal object models for exchange information described in ANSI/ISA-95.00.01-2010 (IEC 62264-1 Mod), Enterprise- Control System Integration – Part 1: Models and Terminology (hereafter referred to as Part 1) using UML object models, tables of attributes, and examples. The models and terminology defined in this part:

  • emphasize good integration practices of control systems with enterprise systems during the entire life cycle of the systems;
  • can be used to improve existing integration capability of manufacturing control systems with enterprise systems; and
  • can be applied regardless of the degree of automation.

Specifically, this part provide a standard terminology and a consistent set of concepts and models for integrating control systems with enterprise systems that will improve communications between all parties involved. Benefits produced will:

  • reduce the user’s time to reach full production levels for new products;
  • enable vendors to supply appropriate tools for implementing integration of control systems to enterprise systems;
  • enable users to better identify their needs;
  • reduce the cost of automating manufacturing processes;
  • optimize supply chains; and
  • reduce life-cycle engineering efforts.

This standard may be used to reduce the effort associated with implementing new product offerings. The goal is to have enterprise systems and control systems that interoperate and easily integrate. It is not the intent of the standards to:

  • suggest that there is only one way of implementing integration of control systems to enterprise systems;
  • force users to abandon their current way of handling integration; or
  • restrict development in the area of integration of control systems to enterprise systems.

Scope

This part of ISA-95, in conjunction with ANSI/ISA-95.00.01-2010 (IEC 62264-1 Mod), Enterprise- Control System Integration – Part 1: Models and Terminology, specifies generic interface content between manufacturing control functions and other enterprise functions. The interface considered is between Level 3 manufacturing systems and Level 4 business systems in the hierarchical model defined in Part 1. The goal is to reduce the risk, cost, and errors associated with implementing the interface.

Since this standard covers many domains, and there are many different standards in those domains, the semantics of this standard are described at a level intended to enable the other standards to be mapped to these semantics. To this end this standard defines a set of elements contained in the generic interface, together with a mechanism for extending those elements for implementations.

The scope of Part 2 is limited to the definition of object models and attributes of the exchanged information defined in Part 1.

This Part 2 standard does not define attributes to represent the object relationships.
