DESCRIPTION

BS EN 61158-4-11:2014


This standard BS EN 61158-4-11:2014 Industrial communication networks. Fieldbus specifications is classified in these ICS categories:
  • 35.110 Networking
  • 35.100.20 Data link layer
  • 25.040.40 Industrial process measurement and control
IEC 61158-4-11:2014 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 data-link 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 standard ISO/IEC 8802-3 medium access control, with provisions for nodes to be added or removed during normal operation and 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. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are: Subclauses 4.6.1, 4.6.4 and 5.4.6, Clause 6 and 7.2 for the loop-architecture are modified to cover the additional specifications for the higher data rate in the loop-architecture.
