Industrial communication networks - Fieldbus specifications - Part 3-2: Data-link layer service definition - Type 2 elements (IEC 61158-3-2:2014/Amd 1:2019)

This part of IEC 61158 provides common elements for basic time-critical messaging communications between devices in an automation environment. 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 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 defines in an abstract way the externally visible service provided by the Type 2 fieldbus data-link layer in terms of:
a) the primitive actions and events of the service;
b) the parameters associated with each primitive action and event, and the form which they take; and
c) the interrelationship between these actions and events, and their valid sequences.
The purpose of this standard is to define the services provided to:
• the Type 2 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model;
• systems management at the boundary between the data-link layer and systems management of the fieldbus reference model.
Type 2 DL-service provides both a connected and a connectionless subset of those services specified in ISO/IEC 8886.
1.2 Specifications
The principal objective of this standard is to specify the characteristics of conceptual data-link layer services suitable for time-critical communications and thus supplement the OSI Basic Reference Model in guiding the development of data-link protocols for time-critical communications. A secondary objective is to provide migration paths from previously-existing industrial communications protocols.
This specification may be used as the basis for formal DL-Programming-Interfaces. Nevertheless, it is not a formal programming interface, and any such interface will need to address implementation issues not covered by this specification, including:
a) the sizes and octet ordering of various multi-octet service parameters;
b) the correlation of paired request and confirm, or indication and response, primitives.
1.3 Conformance
This standard does not specify individual implementations or products, nor does it constrain the implementations of data-link entities within industrial automation systems.

Industrijska komunikacijska omrežja - Specifikacije za procesna vodila - 3-2. del: Definicija opravil na ravni podatkovnih povezav - Elementi tipa 2 (IEC 61158-3-2:2014/Amd 1:2019)

Ta del standarda IEC 61158 določa skupne elemente za osnovne časovno kritične sporočilne komunikacije med napravami v avtomatizacijskem okolju. Izraz »časovno kritičen« se uporablja za predstavitev prisotnosti časovnega okna, v okviru katerega se zahteva dokončanje enega ali več opredeljenih dejanj z določeno stopnjo gotovosti. Zaradi neuspešnega dokončanja opredeljenih dejanj v časovnem oknu je možna odpoved aplikacij, ki zahtevajo dejanja, pri čemer so ogroženi oprema, obrat in morda človeška življenja. Ta standard na abstrakten način določa na zunaj vidno opravilo, ki ga zagotavlja podatkovna povezovalna raven procesnih vodil tipa 2 v smislu:
a) preprostih dejanj in dogodkov opravila;
b) parametrov, povezanih z vsakim preprostim dejanjem in dogodkom, ter obliko, ki jo prevzamejo; in
c) medsebojnih povezav med temi dejanji in dogodki ter njihovimi veljavnimi zaporedji.
Namen tega standarda je opredeliti opravila, ki se zagotavljajo za:
• aplikacijsko raven procesnih vodil tipa 2 na meji med aplikacijo in podatkovno povezovalno ravnjo referenčnega modela procesnega vodila;
• upravljanje sistemov na meji med podatkovno povezovalno ravnjo in upravljanjem sistemov referenčnega modela procesnega vodila.
Protokol na ravni podatkovnih povezav tipa 2 zagotavlja podsklop povezljivih storitev in storitev brez povezave, ki so opisane v standardu ISO/IEC 8886.
1.2 Specifikacije
Glavni cilj tega standarda je določiti značilnosti konceptualnih opravil nivoja podatkovnih povezav, primernih za časovno kritične komunikacije, ter tako dopolniti osnovni referenčni model OSI pri usmerjanju razvoja protokolov časovnih povezav za časovno kritične komunikacije. Drugotni cilj je zagotoviti načrte prehoda iz predhodno obstoječih industrijskih komunikacijskih protokolov.
Ta specifikacija se lahko uporablja kot podlaga za formalne programske vmesnike podatkovne povezave. Vseeno ne gre za formalni programski vmesnik, pri čemer mora vsak tak vmesnik obravnavati izvedbena vprašanja, ki jih ta specifikacija ne zajema, vključno z:
a) velikostmi in oktetnim naročanjem različnih večoktetnih parametrov opravil;
b) korelacijo parnih primitivov za zahtevo in potrjevanje ali navedbo in odziv.
1.3 Skladnost
Ta standard ne določa posameznih implementacij ali izdelkov ter ne omejuje implementacije entitet podatkovnih povezav v okviru sistemov za industrijsko avtomatizacijo.

Overview

EN 61158-3-2:2014/A1:2019 (also published as IEC 61158-3-2:2014/Amd 1:2019) is a CENELEC/IEC amendment for fieldbus specifications that defines the data‑link layer service for Type 2 elements used in industrial communication networks. This amendment updates normative references and bibliography to reflect newer related parts and profiles, and was approved by CENELEC on 2019‑05‑23. It forms part of the IEC/EN 61158 series that specifies fieldbus technologies for industrial automation and real‑time control.

Key topics

• Scope: Service definition for the data‑link (link) layer specifically for Type 2 fieldbus elements within the IEC 61158 family.
• Normative updates: Replaces references to IEC 61158‑4‑2:2014 with IEC 61158‑4‑2:2019 and refreshes the Bibliography to include current editions of related parts and profiles.
• Referenced documents (updated bibliography):
  • IEC 61158‑1:2019 (overview and guidance)
  • IEC 61158‑2:2014 (physical layer)
  • IEC 61158‑5‑2:2019 (application layer service definition – Type 2)
  • IEC 61158‑6‑2:2019 (application layer protocol – Type 2)
  • IEC 61784‑1:2019 and IEC 61784‑2:2019 (fieldbus profiles)
  • ODVA CIP documentation (CIP, ControlNet adaptation)
• Conformance context: Amendment A1 harmonizes the original Part 3‑2 text with later editions of related parts to ensure consistent service definitions across physical, data‑link and application layers for Type 2 fieldbuses.

Applications

• Designed for use in industrial automation, process control, and measurement-and-control systems that rely on deterministic fieldbus communications.
• Useful for:
  • Device and subsystem manufacturers implementing Type 2 fieldbus data‑link services
  • System integrators and network engineers validating interoperability and conformance between devices and controllers
  • Test labs and certification bodies applying up‑to‑date normative references during compliance testing
  • Automation architects mapping communication stacks across physical, data‑link and application layers

Related standards

• EN/IEC 61158 family (Parts 1, 2, 4‑2, 5‑2, 6‑2) - for overview, physical layer, data‑link protocol, and application layer definitions
• IEC 61784 series - fieldbus profiles for real‑time networks
• ODVA CIP publications - practical references for ControlNet/CIP adaptations

This amendment is essential for practitioners who need the current, harmonized data‑link service definitions and up‑to‑date normative references when designing, testing, or certifying Type 2 fieldbus implementations.
