S95 STANDARD
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:
Description | Status | Availability | |
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.
