Together with all of the other
4、sections of BS EN 61158-6, it supersedes BS EN 61158-6:2004 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee AMT/7, Industrial communications Process measurement and control, including Fieldbus.

12、158-6-8, prepared by SC 65C, Industrial networks, of IEC TC 65, Industrial-process measurement, control and automation, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61158-6-8 on 2008-02-01.

13、4. 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; partition 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 na
14、tional 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or by endorsement (dop) 2008-11-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2011-02-01 NOTE Use of some of the associated protocol types is restricted by their intellectual-property-ri
15、ght 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 layer protocol type to be used with physical layer and application layer protocols in type combinations as specified explicitly in the EN 61
16、784 series. Use of the various protocol types in other combinations may require permission from their respective intellectual-property-right holders. IEC and CENELEC draw attention to the fact that it is claimed that compliance with this standard may involve the use of patents as follows, where the
17、xx notation indicates the holder of the patent right: Type 8: DE 197 39 297 C2 PxC “Automatisierungssystem und Steuervorrichtung zur transparenten Kommunikation zwischen verschiedenen Netzwerken.“ US 2002/0042845 A1 PxC “Automation System and connecting Apparatus for the Transparent Communication be
18、tween two Networks.“ 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 with applicants thro
19、ughout the world. In this respect, the statement of the holders of these patent rights are registered with IEC. Information may be obtained from: PxC: Phoenix Contact GmbH for use in the testing and procurement of equipment; as part of an agreement for the admittance of systems into the open systems
20、 environment; as a refinement to the understanding of time-critical communications within OSI. This standard is concerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standard together with other standards positioned within
21、 the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination. BS EN 61158-6-8:2008 7 INDUSTRIAL COMMUNICATION NETWORKS FIELDBUS SPECIFICATIONS Part 6-8: Application layer protocol specification Type 8 elements 1 Scope 1.1 General The fieldbus application
22、 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 basic time-critical and non-time-critical messaging communica
23、tions between application programs in an automation environment and material specific to Type 8 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 be completed with some defined level of certainty. Failure
24、 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 and defines the externally visible behavior provided by th
25、e Type 8 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 applied to the application layer protocol data units; c) the a
26、pplication 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 application entities. The purpose of this standard is to def
27、ine the protocol provided to 1) define the wire-representation of the service primitives defined in IEC 61158-5-8, and 2) define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 8 fieldbus application layer, in conformance with the OSI
28、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 the application layer services defined in IEC 61158-5-8. A sec
29、ondary 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 Conformance This standard does not specify individual implementations or
30、 products, nor does it constrain the implementations of application layer entities within industrial automation systems. BS EN 61158-6-8:2008 8 Conformance is achieved through implementation of this application layer protocol specification. 2 Normative references The following referenced documents a
