IEC 61158-1:2019 pdf download.Industrial communication networks – Fieldbus specifications – Part 1: Overview and guidance for the IEC 61158 and IEC 61784 series
1 Scope
This part of IEC 61 1 58 specifies the generic concept of fieldbuses. This document also presents an overview and guidance for the IEC 61 1 58 series by: • explaining the structure and content of the IEC 61 1 58 series; • relating the structure of the IEC 61 1 58 series to the ISO/IEC 7498-1 OSI Basic Reference Model; • showing the logical structure of the IEC 61 784 series; • showing how to use parts of the IEC 61 1 58 series in combination with the IEC 61 784 series; • providing explanations of some aspects of the IEC 61 1 58 series that are common to the type specific parts of the IEC 61 1 58-5 including the application layer service description concepts and the generic fieldbus data types.

4 Guidelines for implementers and users
4.1 Background and purpose Communication in global markets requires a global understanding of a specification (standard or not). ISO/OSI related specifications provide a common basis for understanding and acceptance between international experts (manufacturers and end-users).The IEC 61 1 58 series specifies a number of different fieldbus types in each of its parts (IEC 61 1 58-2 and the type specific parts of IEC 61 1 58-3-tt, IEC 61 1 58-4-tt, IEC 61 1 58-5-tt and IEC 61 1 58-6-tt). As a result of the editorial harmonization work done by IEC, each PhL, DLL and AL specification within IEC 61 1 58 is shown in a homogeneous way. The description of each layer offers, as far as possible, common views, concepts, definitions, and descriptive methods. NOTE The list of IEC 61 1 58 parts is abbreviated as IEC 61 1 58-3-tt, IEC 61 1 58-4-tt, IEC 61 1 58-5-tt, or IEC 61 1 58-6-tt, where tt represents one or more type numbers. This common approach has been adopted to assist users and implementers in understanding the several specifications. It is also intended to assist in comparing available products and their communications-related features. 4.2 Supported options Most of the fieldbus types specified in the IEC 61 1 58 series include a range of selectable and configurable options within their detailed specifications. In general, only certain restricted combinations of options will interwork or interoperate correctly. The recommended combinations of options are collected in IEC 61 784-1 and IEC 61 784-2. IEC 61 784-1 and IEC 61 784-2 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.
5 Concept of the IEC 61 158 series
Conceptually, a fieldbus is an industrial digital communication network for integration of industrial control and instrumentation devices into a system. Examples of such devices are transducers, sensors, actuators and controllers. The IEC 61 1 58 series specifies a number of fieldbus protocol types. Each protocol type is designed to permit multiple measurement and control devices to communicate. Devices communicate directly only with other devices of the same protocol type. The basic requirements of industrial communication networks for measurement and control are given in Clause 1 1 . Devices which use the same lower-layer protocols in a compatible fashion but differ in their higher-layer protocols may be able to share a lower-layer medium.
