IEC 61158-6-15:2007 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-15, and define the externally visible behaviour associated with their transfer. This standard specifies the protocol of the Type 15 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498) and the OSI application layer structure (ISO/IEC 9545). This first edition and its companion parts of the IEC 61158-6 subseries cancel and replace IEC 61158-6:2003. This part and its Type 15 companion parts also cancel and replace IEC/PAS 62030, published in 2005. This edition of IEC 61158-6 includes the following significant changes from the previous edition:
- deletion of the former Type 6 fieldbus for lack of market relevance;
- addition of new types of fieldbuses;
- partition of part 6 of the third edition into multiple parts numbered -6-2, -6-3,... This bilingual version (2014-12) corresponds to the monolingual English version, published in 2007-12.
