Manufacturing organizations attempting to integrate the plant floor with ERP, supply chain, scheduling, quality, and other systems in their enterprises today have difficult choices to make to base that integration on standards – specifically, what standard to choose. Unfortunately (or maybe fortunately, depending on your point of view) there are several choices available, all of which have strengths and weaknesses, and all of which overlap to some extent. The first paper in this series compared two predominant standards for integrating applications - or, in today's language, for implementing composite applications based on SOA (Services Oriented Architecture):1. OAGIS1 (current version 9.0) from the Open Applications Group Incorporated (OAGi, www.openapplications.org)
2. ISA-95, Enterprise-Control System Integration Standard, from ISA1, (www.isa.org).
This paper is White Paper #2 of the series Standards for Manufacturing Systems Integration, ISA-95 and OAGIS where White Paper #1 is An Overview and Comparison (of ISA-95 and OAGIS). The purpose of this paper is to explain the related standards that overlap or work in conjunction with ISA-95 and OAGIS in developing manufacturing system architectures.
White Paper #3 of this series, Possible Convergence Directions for ISA-95 and OAGIS, presents a convergence path and alternatives for manufacturers currently constructing application integration architectures and for standards committees and working groups working through convergence discussions.
This paper provides a brief overview of standards in use that address the manufacturing operations (Level 3) in full or part, with some description of how they relate to ISA-95 and OAGIS. This paper is intended to provide a reference point for manufacturers developing application integration methods and for standards groups going through the analysis necessary to make convergence decisions.
