This Part 5 standard is based on the use of ISA-95 abstract models previously defined in the ISA-95 Part 1 and Part 2 standards, combined with OAGi verbs to define transaction models for information exchange. It is recognized that other, non-ISA-95 Part 5 transaction protocols are possible and are not deemed invalid as a result of this standard. Transactions occur at all levels within the enterprise and between enterprise partners, and are related to both required and actual activities, but the focus of this standard is the interface between enterprise/business systems and manufacturing systems.
This standard defines business-to-manufacturing transactions and manufacturing-to-business transactions that may be used in relation to the objects that are exchanged between Level 4 and Level 3, as defined in the object models of the Part 1 and Part 2 standards. Models are introduced that provide descriptions of the transactions and explanations of the required transaction processing behavior. Technology-specific implementations to provide this behavior are not defined in this standard. This standard has the intent of providing insight into the level of work required to construct information messages in business-to-manufacturing transactions.
This ISA-95 Part 5 standard defines transactions in terms of information exchanges between applications performing business and manufacturing activities associated with Levels 3 and 4. The exchanges are intended to enable information collection, retrieval, transfer and storage in support of enterprise-control system integration. This Part 5 standard is consistent with the Part 1 models and terminology and Part 2 object model attributes. This standard defines transactions that specify how to exchange the objects defined in Part 1 Clause 7 and Part 2.
The models covered in this standard are: Personnel Model, Equipment Model, Maintenance Model, Material Model, Process Segment Model, Production Capability Model, Product Definition Model, Production Schedule Model, and Production Performance Model.
