What is ISA 95 ? Status · SP 95 committee started in October 1996 · ANSI/ISA 95. 00. 01 available from ISA · Submitted to IEC/ISO · Joint Working Group (JWG 15) to be established · ISA 95. 00. 02 in draft, out for vote · Out for committee ballot and public comment · ISA 95. 00. 03 in draft · Still under development in the committee · World Batch Forum · Developing XML Schemas for the exchanged information

Why Did We Start SP 95 ? · Integration of business (logistics) systems to manufacturing is hard to do · Different systems, cultures, terminology. . . · Many benefits expected from standardization and documentation of “best practices” · Effective operation of manufacturing is hard to do · MES solutions are too related to processing methods and too industry-specific · Many benefits expected from standardization and documentation of “best practices”

Business Defines the Need · There must always be a business need for information to be exchanged · Requirements for exchanged information are always driven by business needs & business processes · Typical Business Drivers: · · · Available To Promise Reduced Cycle Time Supply Chain Optimization Asset Efficiency Agile Manufacturing

How Does S 95* Help? · Separate the business processes from the manufacturing processes · Allow changes in production processes without requiring unnecessary changes scheduling and logistics processes · Provide a clear demarcation of responsibilities and functions · Provide a clear description of Alternate Logistics Strategies Make to Order Make Engineer. Configure to to to Stock Order S 95. 01 PDXI NAMUR S 88. 01 SME Batch Discrete Continuous Manufacturing Models Alternate Manufacturing Strategies * S 95 is used as a short form for ANSI/ISA 95

Scope of S 95. 01 · The definition of the scope of the manufacturing control domain · A definition of the functions associated with the interface between control functions and enterprise functions · A definition of the information which is shared between control functions and enterprise functions · Based on the Purdue Reference Model for CIM and MESA model

Exception Handling In Control Actions The safety interlock logic takes precedence over phase logic or process interlock logic. Typically this logic, when required, is implemented in an independent safety interlock system. Safety Interlock Control Module Process Interlock Control Module Exception Logic The process interlock logic takes precedence over phase logic and manual override logic. Typically, this logic is implemented in the DPCS. Phase Logic Control step (command) Control Action Control Module/Control Action State/Mode Equipment Module Control Module Inhibit manual override (Interlock from phase logic), Also sent to console to inhibit choice of manual mode Console Control Module/Control Action State/Mode Field I/O Exception Logic Inputs to Control Action Logic: - Set manual mode - Command from operator's console
