Industrial-process measurement, control and automation - Evaluation of system properties for the purpose of system assessment - Part 1: Terminology and basic concepts

IEC 61069-1:2016 defines the terminology and outlines basic concepts in the assessment of a basic process control system (BPCS) and a basic discrete control system (BDCS). These two general system types cover the areas of discrete, batch and continuous applications. In IEC 61069 these two, BPCS and BDCS, together are referred to as "basic control system(s)", (BCS). This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Reorganization of the material of IEC 61069-1:1991 to make the overall set of standards more organized and consistent;
- IEC TS 62603-1:2014 has been incorporated into this edition.

Mesure, commande et automation dans les processus industriels - Appréciation des propriétés d'un système en vue de son évaluation - Partie 1: Terminologie et principes de base

L'IEC 61069-1:2016 définit la terminologie et met en exergue les principes de base de l'évaluation d'un système de commande de processus de base (BPCS, Basic Process Control System) et d'un système de commande discret de base (BDCS, Basic Discrete Control System). Ces deux types de systèmes généraux couvrent les applications discrètes, par lots et continues. Ces deux systèmes, BPCS et BPDS sont conjointement appelés "systèmes de commande de base" (BCS, Basic Control System) dans l'IEC 61069. Cette deuxième édition annule et remplace la première édition parue en 1991. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- Réorganisation des informations contenues dans l'IEC 61069-1:1991 visant à mieux organiser l'ensemble complet de normes et à le rendre plus cohérent;
- L'IEC TS 62603-1:2014 a été incorporée dans cette édition.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entruste
