適用范圍：The Manufacturing Message Specification is an application layer standard designed to support messaging communications to and from programmable devices in a Computer Integrated Manufacturing (CIM) environment. 1 Specifications This part of ISO 9506 specifies: a) procedures for a single protocol for the transfer of data and control information from one application entity to a peer application entity in the MMS-context; b) the means of selecting the services to be used by the application entities while communicating in the MMS-context; c) the structure of the Manufacturing Messaging Specification Protocol Data Units used for the transfer of data and control information. 2 Procedures The procedures are defined in terms of a) the interactions between peer application entities through the exchange of Manufacturing Message Specification Application Protocol Data Units; b) the interactions between an MMS-provider and the MMS-user in the same system through the exchange of MMS primitives; c) the interactions between an MMS-provider and the abstract services provided by the underlying communication system. 3 Applicability These procedures are applicable to instances of communication between systems that support MMS within the application layer of the OSI Reference Model, and that require the ability to interconnect in an open systems interconnection environment. 4 Conformance This part of ISO 9506 also specifies conformance requirements for systems implementing these procedures. This part of ISO 9506 does not contain tests to demonstrate compliance with such requirements.
