What is BS EN 61158-4-13 – Type 13 elements of data-link layer protocol about?
BS EN 61158-4-13 is one of a series produced to facilitate the interconnection of automation system components. It is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC 61158-1.
The data-link layer provides basic time-critical messaging communications between devices in an automation environment.
BS EN 61158-4-13 provides communication opportunities to all participating data-link entities
- In a synchronously-starting cyclic manner, according to a pre-established schedule, and
- In a cyclic or acyclic asynchronous manner, as requested each cycle by each of those data-link entities
Thus, BS EN 61158-4-13 can be characterized as one which provides cyclic and acyclic access asynchronously but with a synchronous restart of each cycle.
Who is BS EN 61158-4-13 – Type 13 elements of data-link layer protocol for?
BS EN 61158-4-13 on industrial communication networks is useful for:
- IT industry /software programmers
- Internet engineering task forces
- Internet service providers
- Telecommunication companies
- The automation industry
- Networking sectors
Why should you use BS EN 61158-4-13 – Type 13 elements of data-link layer protocol?
Profiles provide a simple multi-attribute means of summarizing an implementation’s capabilities, and thus its applicability to various time-critical communications needs.
BS EN 61158-4-13 specifies
- 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
- 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 one millisecond
- 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
- Procedures for giving cyclic and acyclic communication opportunities for time-critical data transmission with prioritized access
- Procedures for giving communication opportunities based on ISO/IEC 8802-3 medium access control, with provisions for nodes to be added or removed during normal operation
- The structure of the fieldbus DLPDUs used for the transfer of data and control information by the protocol of BS EN 61158-4-13, and their representation as physical interface data units
Overall, the guidance of BS EN 61158-4-13 helps you to gain a better understanding of type-13 elements of the data-link layer protocol. This helps you to implement industrial communication networks effectively.
