Industrial communication networks - Fieldbus specifications - Part 4-2: Data-link layer protocol specification - Type 2 elements
IEC 61158-4-2:2010(E) describes the protocol that provides communication opportunities to all participating data-link entities, sequentially and in a cyclic synchronous manner. Foreground scheduled access is available for time-critical activities together with background unscheduled access for less critical activities. Deterministic and synchronized transfers can be provided at cyclic intervals up to 1 ms and device separations of 25 km. This performance is adjustable dynamically and on-line by re-configuring the parameters of the local link whilst normal operation continues. By similar means, DL connections and new devices may be added or removed during normal operation. This protocol provides means to maintain clock synchronization across an extended link with a precision better than 10 s. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. The main changes with respect to the previous edition are: -Clause 2 and Bibliography: update of normative and bibliographic references; - subclause 3.5: update of abbreviations; - subclause 7.6: updates of the Ethernet Link object; - subclause 7.7: minor update of the Devicenet object (additional attribute); - new subclauses 7.9 and 7.10: new DLR and QoS objects; - new Clause 10: new DLR protocol.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 4-2. del: Specifikacija protokola na nivoju podatkovnih povezav (IEC 61158-4-2:2010)
Nivo podatkovnih povezav omogoča osnovne časovno kritične sporočilne komunikacije med napravami v avtomatizacijskem okolju. Ta protokol omogoča komunikacijske priložnosti za vse sodelujoče entitete podatkovnih povezav, zaporedno in na cikličen sinhroni način. Razporejen dostop v ospredju je na voljo za časovno kritične aktivnosti skupaj z nerazporejenim dostopom v ozadju za manj kritične aktivnosti. Deterministični in sinhronizirani prenosi so lahko omogočeni v cikličnih intervalih do 1 ms in ločenosti naprav 25 km. Ta zmogljivost je prilagodljiva dinamično in spletno s konfiguracijo parametrov lokalne povezave, medtem ko se običajno delovanje nadaljuje. Na podoben način se lahko med običajnim delovanjem dodajo ali odstranijo podatkovne povezave in nove naprave. Ta protokol zagotavlja sredstva za vzdrževanje sinhronizacije ure prek razširjene povezave z natančnostjo, boljšo od 10 μs. Ta protokol optimizira vsako priložnost dostopa s povezovanjem več DLDSU in povezanih DLPCI v en sam DLPDU in s tem izboljšuje učinkovitost prenosa podatkov za entitete podatkovnih povezav, ki so aktivni vir več podatkovnih tokov. Največja velikost sistema je neomejeno število povezav 99 vozlišč, vsako z 225 naslovi DLSAP. Vsaka povezava ima največ 224 povezanih DLCEP-ov omrežnih vrstnikov in izdajateljev.
