IEC 61158-5-19:2014 defines the services provided to the FAL user at the boundary between the user and the application layer of the fieldbus reference model, and Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model. This standard specifies the structure and services of the IEC 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:- introducing connections based on a producer-consumer model;- introducing additional mechanisms to realize features such as timestamping and oversampling;- improving the hotplug and redundancy features;- improving the phase switching and the error handling;- editorial improvements.
