Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Introduction
As a crucial part of manufacturing systems with increased complexity, the automation and control
applications enabled by the advanced process control and optimization (APC-O) methodology and
solutions perform the operations directed by production planning and scheduling. This work will
initially deal with the specific use of APC-O to enable integration of manufacturing operations
management (MOM) with the automation and control of manufacturing processes and equipment.
Automation solutions composed of software and hardware components are provided by different
suppliers to accomplish APC-O functions. Due to the diversity of development environments and the
variety of demand focus, the automation solutions from various suppliers are isolated and relatively
independent. These differences make the integration of automation solutions difficult. Consequently,
the customers could purchase different automation solution components with redundant and duplicated
functions, resulting in a waste of resources and limited interoperability. The proposed standard offers
a reference interoperability framework for advanced process control and optimization. It is intended to
maximize the integration and interoperability of automation solutions.
This document provides a consistent framework for integration and interoperability between
APC-O systems, parts of an APC-O system, Level 2 automated process control systems, and Level
3 manufacturing operations management systems. It builds on the functional models defined by
ISO 15746-1 by defining activity models for APC-O systems and the information exchange requirements
needed to support those activity models. The modelled activities operate within Level 2 and Level 3
with interaction between each level.
It is not the intent of this document to suggest that there is only one way of implementing APC-O or to
force users to abandon their current way of implementing APC-O.
The target users of this standard include: users and providers of advanced process control and
optimization solutions, such as, project solution suppliers, automation systems integrators, production
departments of companies, process engineers, independent software testing organizations,
implementation and consulting service organizations of advanced process control and optimization
software, and relevant government and academic organizations.
