The ISA S95 Standard for Enterprise-Control System Integration defines interfaces between applications at the Industrial Control Level and applications at the MES (Manufacturing Execution Systems) Level. As such, it bridges the gap between control-level communications which are typically implemented using OPC, and business-level applications using EDI and various B2B standards.
The standard is being defined in "parts" which are being individually released as they are approved.
The official S95 Part 1 standard is defined by ANSI / ISA - 95.00.01-2000, which is currently available from the ISA as follows:
|Part 1||Models and Terminology||Issued||Now|
|Part 2||Data Structures and Attributes||Issued||Now|
|Part 3||Models of Manufacturing Operations Management||Issued||Now|
|Part 4||Object Models and Attributes of Manufacturing Operations Management||?||?|
|Part 5||Business-to-Manufacturing Transactions||Issued||Now|
The S95 standard includes the PERA Reference Architecture for CIM (Appendix 1 of Part 1) and includes concepts from the PERA Handbook for Enterprise Integration.
This standard is explained further in the following presentations:
