Описание
IEC 61158-3-2:2014 defines the services provided to the Type 2 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. Type 2 DL-service provides both a connected and a connectionless subset of those services specified in ISO/IEC 8886. This second edition cancels and replaces the first edition published in 2007. It constitutes a technical revision. The main changes are: Correction of references for fixed tag usage in 4.6.3.6. and update of core bibliographic references (original source documents from consortium)
