1.1 General<\/b><\/p>\n
The data-link layer provides basic time-critical messaging communications between devices in an automation environment.<\/p>\n
This protocol provides communication opportunities to all participating data-link entities<\/p>\n
in a synchronously-starting cyclic manner, according to a pre-established schedule, or<\/p>\n<\/li>\n
in an acyclic manner, as requested by each of those data-link entities.<\/p>\n<\/li>\n<\/ol>\n
Thus this protocol can be characterized as one which provides cyclic and acyclic access asynchronously but with a synchronous restart of each cycle.<\/p>\n
1.2 Specifications<\/b><\/p>\n
This standard specifies<\/p>\n
procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entities forming the distributed datalink service provider;<\/p>\n<\/li>\n
procedures for giving communications opportunities to all participating DL-entities, sequentially and in a cyclic manner for deterministic and synchronized transfer at cyclic intervals up to 64 ms;<\/p>\n<\/li>\n
procedures for giving communication opportunities available for time-critical data transmission together with non-time-critical data transmission without prejudice to the time-critical data transmission;<\/p>\n<\/li>\n
procedures for giving cyclic and acyclic communication opportunities for time-critical data transmission with prioritized access;<\/p>\n<\/li>\n
procedures for giving communication opportunities based on standard ISO\/IEC 8802-3 medium access control, with provisions for nodes to be added or removed during normal operation;<\/p>\n<\/li>\n
the structure of the fieldbus DLPDUs used for the transfer of data and control information by the protocol of this standard, and their representation as physical interface data units.<\/p>\n<\/li>\n<\/ol>\n
1.3 Procedures<\/b><\/p>\n
The procedures are defined in terms of<\/p>\n
the interactions between peer DL-entities (DLEs) through the exchange of fieldbus DLPDUs;<\/p>\n<\/li>\n
the interactions between a DL-service (DLS) provider and a DLS-user in the same system through the exchange of DLS primitives;<\/p>\n<\/li>\n
the interactions between a DLS-provider and a Ph-service provider in the same system through the exchange of Ph-service primitives.<\/p>\n<\/li>\n<\/ol>\n
1.4 Applicability<\/b><\/p>\n
These procedures are applicable to instances of communication between systems which support time-critical communications services within the data-link layer of the OSI or fieldbus reference models, and which require the ability to interconnect in an open systems interconnection environment.<\/p>\n
Profiles provide a simple multi-attribute means of summarizing an implementation\u2019s capabilities, and thus its applicability to various time-critical communications needs.<\/p>\n
1.5 Conformance<\/b><\/p>\n
This standard also specifies conformance requirements for systems implementing these procedures. This standard does not contain tests to demonstrate compliance with such requirements.<\/p>\n
