IEC 61158-6-14

IEC 61158-6-14:2014 defines the protocol provided to define the wire-representation of the service primitives defined in IEC 61158-5-14, and define the externally visible behavior associated with their transfer. This standard specifies the protocol of the Type 14 fieldbus application layer, in conformance with the OSI Basic Reference Model (ISO/IEC 7498-1) and the OSI application layer structure (ISO/IEC 9545). This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are:
- corrections of editorial errors;
- specification changes for CPF4;
- update of the requirements for all conformance classes;
- update of the requirements for all conformance services.
