It is related to other standards in the set as defined by the “three-layer” fieldbus
40、 reference model described in IEC 61158-1. The data-link protocol provides the data-link service by making use of the services available from the physical layer. The primary aim of this standard is to provide a set of rules for communication expressed in terms of the procedures to be carried out by
41、peer data-link entities (DLEs) at the time of communication. These rules for communication are intended to provide a sound basis for development in order to serve a variety of purposes: a) as a guide for implementers and designers; b) for use in the testing and procurement of equipment; c) as part o
42、f an agreement for the admittance of systems into the open systems environment; d) 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. B
43、y using this standard together with other standards positioned within the OSI or fieldbus reference models, otherwise incompatible systems may work together in any combination. NOTE Use of some of the associated protocol types is restricted by their intellectual-property-right holders. In all cases,
44、 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 profile parts. Use of the vario
45、us protocol types in other combinations may require permission from their respective intellectual-property-right holders. The International Electrotechnical Commission (IEC) draws attention to the fact that it is claimed that compliance with this document may involve the use of patents concerning Ty
