What is BS EN IEC 61158-1 - Fieldbus specifications about?
BS EN IEC 61158-1 is the first part of the BS EN IEC 61158 series on industrial communication networks, and specifies the generic concept of fieldbuses and presents an overview and guidance for the series by:
- Explaining the structure and content of the IEC 61158 series
- Relating the structure of the IEC 61158 series to the ISO/IEC 7498-1 OSI Basic Reference Model
- Showing the logical structure of the IEC 61784 series
- Showing how to use parts of the IEC 61158 series in combination with the IEC 61784 series
- Providing explanations of some aspects of the IEC 61158 series that are common to the type-specific parts of the IEC 61158-5 including the application layer service description concepts and the generic Fieldbus data types
NOTE 1: Combinations of protocol types are specified in IEC 61784-1 and IEC 61784-2.
Who is BS EN IEC 61158-1 - Fieldbus specifications for?
BS EN IEC 61158-1 on Industrial communication networks. Fieldbus specifications are useful for:
- The IT industry / Software programmers
- Internet engineering task forces
- The automation industry
- Internet service providers
- The telecommunication industry
Why should you use BS EN IEC 61158-1 - Fieldbus specifications?
Communication in global markets requires a global understanding of a specification (standard or not). BS EN IEC 61158-1 specification provide a common basis for understanding and acceptance between international experts (manufacturers and end-users).
Examples are
- ISO/IEC 7498-1 for general layering and structuring
- ISO/IEC 9545 for general application layer modelling
- ISO/IEC 8886 for data-link layer modelling
The description of each layer offers, as far as possible, common views, concepts, definitions, and descriptive methods. This common approach has been adopted to assist users and implementers in understanding several specifications. It is also intended to assist in comparing available products and their communications-related features. IEC 61784-1 and IEC 61784-2 provide users and implementers with details of supported Fieldbus specifications based on selected options that are intended to work together consistently and correctly. In most cases, available product demonstrations and working plant experience support these profiles.
The benefits gained from using a common and formal style to specify the communication system are:
- The common look and feel of a specification save effort during an evaluation
- A common structure helps to identify and to specify common parts and contents
- The common approach represents the first step to ensure long-term quality and stability
- The missing parts and items of any specification are more readily identified by comparison with the other specifications, leading to a simplified review and evaluation procedure
- A common basis facilitates the development of test and certification procedures
- The modular concepts support future enhancements, extensions, and adaptation of new technologies
