What is this BS EN IEC 61158-3-12 - Industrial communication networks - Fieldbus specifications about?
IEC 61158 series is produced to facilitate the interconnection of automation system components.
BS EN IEC 61158-3-12 provides common elements for basic time-critical messaging communications between devices in an automation environment. The term “time-critical” is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.
BS EN IEC 61158-3-12 defines in an abstract way the externally visible service provided by the Type 12 fieldbus data-link layer in terms of the primitive actions and events of the service, the parameters associated with each primitive action and event, and the form which they take.
NOTE: BS EN IEC 61158-3-12 does not specify individual implementations or products, nor does it constrain the implementations of data-link entities within industrial automation systems.
Who is BS EN IEC 61158-3-12 - Industrial communication networks - Fieldbus specifications for?
BS EN IEC 61158-3-12 on type 12 fieldbus specifications for industrial communication network is useful for:
- Data processing and storage companies
- Communication industries
- Industrial automation system
Why should you use BS EN IEC 61158-3-12 - Industrial communication networks - Fieldbus specifications?
The purpose of BS EN IEC 61158-3-12 is to define the services provided to the Type 12 fieldbus application layer at the boundary between the application and datalink 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.
BS EN IEC 61158-3-12 provides with you the characteristics of conceptual datalink layer services suitable for time-critical communications, and thus supplement the OSI Basic Reference Model in guiding the development of data-link protocols for time-critical communications.
BS EN IEC 61158-3-12 provides you with migration paths from previously existing industrial communications protocols.
