BAS EN 61158-3-2:2010

IEC 61158-3-2:2007 defines in an abstract way the externally visible service provided by the Type 2 fieldbus data-link layer in terms of:<br /> - the primitive actions and events of the service;<br /> - the parameters associated with each primitive action and event, and the form which they take;<br /> - the interrelationship between these actions and events, and their valid sequences. This first edition and its companion parts of the IEC 61158-3 subseries cancel and replace IEC 61158-3:2003. This edition of this part constitutes a minor revision. This part and its companion Type 2 parts also cancel and replace IEC/PAS 62410, published in 2005. This edition includes the following changes:<br /> - deletion of the former Type 6 fieldbus, and the placeholder for a Type 5 fieldbus data-link layer, for lack of market relevance;<br /> - addition of new types of fieldbuses;<br /> - division of this part into multiple parts numbered 3-1, 3-2,..., 3-19. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2007-12.
