Publicly available specification Cancelled

Industrial communication networks - Fieldbus specifications - Part 4-22: Data-link layer protocol specification - Type SNpTYPE elements

IEC/PAS 61158-4-22:2009(E) provides basic time-critical messaging communications between devices in an automation environment. This protocol 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. It contains an additional profile - SNpTYPE - which may be integrated into a future new edition of the IEC 61158-4 series.

Industrial communication networks - Fielbus specifications - Part 4-22: Data-link layer protocol specification - Type 22 elements

IEC 61158-4-22:2010 describes 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; 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 standard cancels and replaces IEC/PAS 61158-4-22 published in 2009. This bilingual version published in 2012-01 corresponds to the English version published in 2010-08.
