Cause and Effect Matrix
This document addresses the setting and implementation of C&E matrices for a consistent use in engineering activities. It aims to describe a simple format used to support a consistent exchange of information between different engineering disciplines involved in project or maintenance activities. The document defines the minimum requirements of the C&E matrix content, which is derived from existing design documents, for example P&ID or verbal descriptions. The transfer of the relations defined in C&E matrices into a functional or source code for the application programming of PLC/DCS is out of the scope of this document. In addition, this document does not cover the implementation of complex and/or sequential logics at a dedicated automation platform, which will require additional stipulations to be done/ followed. It is understood, that C&E matrices in fact can be used to document the fault reactions of the plant equipment and therefore can be used as reference point for the necessary safety verifications to be applied. C&E matrices as defined in this document do not have the same scope as Fishbone or Ishikawa diagrams, which are often named in the literature as cause and effect diagrams.

Matrice des causes et effets
IEC 62881:2018 traite de la définition et de la mise en œuvre des matrices C&E pour une utilisation cohérente dans le cadre des activités d'ingénierie. Son objectif est de spécifier un format simple de prise en charge d'un échange cohérent d'informations entre les différentes disciplines techniques intervenant dans les activités liées au projet ou de maintenance. Le document définit les exigences minimales concernant le contenu des matrices C&E issu des documents de conception existants, par exemple des plans de tuyauterie et d'instrumentation ou des descriptions verbales. La transformation des relations définies dans les matrices C&E en un code fonctionnel ou source pour la programmation d'application des AP/DCS ne relève pas du domaine d'application du présent document. De plus, le présent document ne traite pas de la mise en œuvre de logiques complexes et/ou séquentielles sur une plate-forme d'automatisation dédiée, qui exige la définition/le respect de spécifications supplémentaires. Il est entendu que les matrices C&E peuvent en fait servir à documenter les réactions aux anomalies des équipements d'une installation et par conséquent être également utilisées comme point de référence pour les vérifications de sécurité nécessaires à effectuer. Les matrices C&E telles que définies dans le présent document ne relèvent pas du même domaine d’application que les diagrammes en arête de poisson ou diagrammes d’Ishikawa, également appelés diagrammes de causes-effets dans les ouvrages de référence.
Preglednica vzrokov in učinkov (IEC 62881:2018)
Ta dokument obravnava pripravo ter uvedbo preglednic vzrokov in učinkov za dosledno uporabo v inženirskih aktivnostih. Opisuje preprost format za zagotavljanje dosledne izmenjave informacij med različnimi inženirskimi disciplinami, ki sodelujejo pri projektnih ali vzdrževalnih dejavnostih. Dokument določa minimalne zahteve za vsebino preglednice vzrokov in učinkov, ki izhaja iz obstoječih projektnih dokumentov, na primer orodja P&ID ali besednih opisov.
Prenos odnosov, določenih v preglednicah vzrokov in učinkov, v funkcionalno ali izvorno kodo za programiranje aplikacij PLC/DCS, ne spada na področje uporabe tega dokumenta. Poleg tega ta dokument ne zajema izvajanja kompleksnih in/ali zaporednih logik na namenski platformi za avtomatizacijo, za kar bo treba pripraviti dodatne predpise in jih upoštevati.
Jasno je, da je mogoče preglednice vzrokov in učinkov dejansko uporabiti za dokumentiranje napak v opremi obrata in jih je mogoče uporabiti kot referenčno točko za potrebna varnostna preverjanja.
Preglednice vzrokov in učinkov, kot so opredeljene v tem dokumentu, nimajo enakega obsega kot sheme Fishbone ali Ishikawa, ki se v literaturi pogosto imenujejo sheme vzrokov in učinkov.

CAUSE AND EFFECT MATRIX
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 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62881 has been prepared by IEC technical committee 65: Industrial-process measurement, control and automation. The text of this standard is based on the following documents: FDIS Report on voting 65/701/FDIS 65/711/RVD

INTRODUCTION Efficient engineering and reliable operation of automated plants strongly depend on clear and unambiguous description of regulatory controls and logic interlocks. For regulatory controls this description can typically be done for example via process flow diagrams and P&IDs (ISO 10628), which are accepted by process and I&C staff in engineering and operation of manufacturing and process plants. Regarding logic interlocks the widely distributed logic or functional diagrams are very often regarded by process engineers and plant operators as too complex (especially
