Together with all of the other sections of BS EN 61158-6, it supersedes BS EN 61158-6:2004 which is withdrawn. The UK participation in its preparation was entrusted
4、to Technical Committee AMT/7, Industrial communications Process measurement and control, including fieldbus. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Use

15、ote and was approved by CENELEC as EN 61158-6-17 on 2008-02-01. This and the other parts of the EN 61158-6 series supersede EN 61158-6:2004. With respect to EN 61158-6:2004 the following changes were made: deletion of Type 6 fieldbus for lack of market relevance; addition of new fieldbus types; part
16、ition into multiple parts numbered 6-2, 6-3, 6-20. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2008-11-01 latest date by which the national standards conflicting with the
17、EN have to be withdrawn (dow) 2011-02-01 NOTE Use of some of the associated protocol types is restricted by their intellectual-property-right holders. In all cases, the commitment to limited release of intellectual-property-rights made by the holders of those rights permits a particular data-link la

Use of the various protocol types in other combinations may require permission from their respective intellectual-property-right holders. IEC and CENE
19、LEC draw attention to the fact that it is claimed that compliance with this standard may involve the use of patents as follows, where the xx notation indicates the holder of the patent right: Type 17: PCT Application No. PCT/JP2004/011537 YEC Communication control method PCT Application No. PCT/JP20
20、04/011538 YEC Communication control method IEC and CENELEC take no position concerning the evidence, validity and scope of these patent rights. The holders of these patent rights have assured IEC that they are willing to negotiate licences under reasonable and non-discriminatory terms and conditions

25、e 17 elements 1 Scope 1.1 General The fieldbus application layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a “window between corresponding application programs.” This standard provides common elements for bas
26、ic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 17 fieldbus. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to
27、 be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life. This standard specifies interactions between remote applications
28、 and defines the externally visible behavior provided by the Type 17 fieldbus application layer in terms of a) the formal abstract syntax defining the application layer protocol data units conveyed between communicating application entities; b) the transfer syntax defining encoding rules that are ap
29、plied to the application layer protocol data units; c) the application context state machine defining the application service behavior visible between communicating application entities; d) the application relationship state machines defining the communication behavior visible between communicating
30、application entities. The purpose of this standard is to define the protocol provided to 1) define the wire-representation of the service primitives defined in IEC 61158-5-17, and 2) define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Ty
31、pe 17 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI application layer structure (ISO/IEC 9545). 1.2 Specifications The principal objective of this standard is to specify the syntax and behavior of the application layer protocol that conveys
32、the application layer services defined in IEC 61158-5-17. A secondary objective is to provide migration paths from previously-existing industrial communications protocols. It is this latter objective which gives rise to the diversity of protocols standardized in the IEC 61158-6 series. 1.3 Conforman
33、ce This standard does not specify individual implementations or products, nor does it constrain the implementations of application layer entities within industrial automation systems.
