In all cases, the commitment to limited release of intellectual-property-rights made by the holders

16、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 61784 series. Use of the various protocol types in other combinations may require permission from their respective

17、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 xx notation indicates the holder of the patent right: Type 8: DE 197 39 297 C2 PxC “Automatisierungssystem und St

18、euervorrichtung zur transparenten Kommunikation zwischen verschiedenen Netzwerken.“ US 2002/0042845 A1 PxC “Automation System and connecting Apparatus for the Transparent Communication between two Networks.“ IEC and CENELEC take no position concerning the evidence, validity and scope of these patent

19、 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 throughout the world. In this respect, the statement of the holders of these patent rights are registered with IEC. In

20、formation 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 environment; as a refinement to the understanding of time-critical communications within OSI. This standard is co

21、ncerned, in particular, with the communication and interworking of sensors, effectors and other automation devices. By using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination. BS EN

22、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 layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect

23、, 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 communications between application programs in an automation environment and material specific to Type 8 fieldbus. The term

24、 “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 to complete specified actions within the time window risks failure of the applications requesting the actions, wi

25、th attendant risk to equipment, plant and possibly human life. This standard specifies interactions between remote applications and defines the externally visible behavior provided by the Type 8 fieldbus application layer in terms of a) the formal abstract syntax defining the application layer proto

26、col 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 application context state machine defining the application service behavior visible between communicating applicati

27、on entities; d) the application relationship state machines defining the communication behavior visible between communicating 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 61158-5-8,

28、 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 Basic Reference Model (ISO/IEC 7498) and the OSI application layer structure (ISO/IEC 9545). 1.2 Specifications Th

29、e 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 secondary objective is to provide migration paths from previously-existing industrial communications protocols. It is

30、 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 products, nor does it constrain the implementations of application layer entities within industrial automation sy

31、stems. 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 are indispensable for the application of this document.
