Die Norm DIN EN ISO 13849-1 "Sicherheit von Maschinen - Sicherheitsbezogene Teile von Steuerungen" macht Vorgaben für die Gestaltung von sicherheitsbezogenen Teilen von Steuerungen. Dieser Report ist eine Aktualisierung des gleichnamigen BGIA-Reports 2/2008. Er stellt die wesentlichen Inhalte der Norm in ihrer dritten Ausgabe von 2016 vor und erläutert deren Anwendung an zahlreichen Beispielen aus den Bereichen Elektromechanik, Fluidtechnik, Elektronik und programmierbarer Elektronik, darunter auch Steuerungen gemischter Technologie. Der Zusammenhang der Norm mit den grundlegenden Sicherheitsanforderungen der Maschinenrichtlinie wird aufgezeigt und mögliche Verfahren zur Risikoabschätzung werden vorgestellt. Auf der Basis dieser Informationen erlaubt der Report die Auswahl des erforderlichen Performance Level PLr für steuerungstechnische Sicherheitsfunktionen. Die Bestimmung des tatsächlich erreichten Performance Level PL wird detailliert erläutert. Auf die Anforderungen zum Erreichen des jeweiligen Performance Level und seine zugehörigen Kategorien, auf die Bauteilzuverlässigkeit, Diagnosedeckungsgrade, Softwaresicherheit und Maßnahmen gegen systematische Ausfälle sowie Fehler gemeinsamer Ursache wird im Detail eingegangen. Hintergrundinformationen zur Umsetzung der Anforderungen in die steuerungstechnische Praxis ergänzen das Angebot. Zahlreiche Schaltungsbeispiele zeigen bis auf die Ebene der Bauteile hinunter, wie die Performance Level a bis e mit den Kategorien B bis 4 in den jeweiligen Technologien technisch umgesetzt werden können. Sie geben dabei Hinweise auf die verwendeten Sicherheitsprinzipien und sicherheitstechnisch bewährte Bauteile. Zahlreiche Literaturhinweise dienen einem tieferen Verständnis der jeweiligen Beispiele. Der Report zeigt, wie die Anforderungen der DIN EN ISO 13849-1 in die technische Praxis umgesetzt werden können, und leistet damit einen Beitrag zur einheitlichen Anwendung und Interpretation der Norm auf nationaler und internationaler Ebene.

The EN ISO 13849-1 standard, “Safety of machinery – Safety-related parts of control systems”, contains provisions governing the design of such parts. This report is an update of BGIA Report 2/2008e of the same name. It describes the essential subject-matter of the standard in its third, revised 2015 edition, and explains its application with reference to numerous examples from the fields of electromechanics, fluidics, electronics and programmable electronics, including control systems employing mixed technologies. The standard is placed in its context of the essential safety requirements of the Machinery Directive, and possible methods for risk assessment are presented. Based upon this information, the report can be used to select the required Performance Level PLr for safety functions in control systems. The Performance Level PL which is actually attained is explained in detail. The requirements for attainment of the relevant Performance Level and its associated Categories, component reliability, levels of diagnostic coverage, software safety and measures for the prevention of systematic and common-cause failures are all discussed comprehensively. Background information is also provided on implementation of the requirements in real-case control systems. Numerous example circuits show, down to component level, how Performance Levels a to e can be engineered in the selected technologies with Categories B to 4. The examples provide information on the safety principles employed and on components with well-tried safety functionality. Numerous literature references permit closer study of the examples provided. The report shows how the requirements of EN ISO 13849-1 can be implemented in engineering practice, and thus makes a contribution to consistent application and interpretation of the standard at national and international level.

Bei der Vielzahl an Steuergeräten in heutigen Anwendungen spielt die Funktionale Sicherheit elektronischer Systeme eine bedeutende Rolle. Immer wenn Sicherheitsfunktionen in einer Maschine mittels Steuerung realisiert werden, muss der Hersteller die Steuerungskomponenten so auswählen und miteinander kombinieren, dass diese eine der Gefährdung entsprechende Ausfallwahrscheinlichkeit haben. Der erste Teil der DIN EN ISO 13849-1 "Sicherheit von Maschinen" enthält allgemeine Gestaltungsleitsätze für sicherheitsbezogene Teile von Steuerungen. Die Norm beschreibt das Verfahren, mit dem der erforderliche Performance Level (PL) bestimmt wird und wie der Nachweis über den erreichten Performance Level (PL) zu führen ist. Dieser Praxis-Band befasst sich u. a. mit dem Zusammenhang zwischen Norm und den grundlegenden Anforderungen der EG-Maschinenrichtlinie 2006/42/EG. Die normativen Forderungen werden praxisgerecht erläutert und anhand von Beispielen veranschaulicht. Inhaltliche Gliederung: Vorwort // Einleitung // Anforderungen der EG- MRL // Risikominderung/Risikobeurteilung // Identifizierung notwendiger Sicherheitsfunktionen und deren Eigenschaften // Bestimmung erforderlichen Performance Level // Ergänzende Schutzmaßnahmen // Gestaltung sicherer Steuerungen.

The safe and reliable performance of many systems with which we interact daily has been achieved through the analysis and management of risk. From complex infrastructures to consumer durables, from engineering systems and technologies used in transportation, health, energy, chemical, oil, gas, aerospace, maritime, defence and other sectors, the management of risk during design, manufacture, operation and decommissioning is vital. Methods and models to support risk-informed decision-making are well established but are continually challenged by technology innovations, increasing interdependencies, and changes in societal expectations. Risk, Reliability and Safety contains papers describing innovations in theory and practice contributed to the scientific programme of the European Safety and Reliability conference (ESREL 2016), held at the University of Strathclyde in Glasgow, Scotland (25—29 September 2016). Authors include scientists, academics, practitioners, regulators and other key individuals with expertise and experience relevant to specific areas. Papers include domain specific applications as well as general modelling methods. Papers cover evaluation of contemporary solutions, exploration of future challenges, and exposition of concepts, methods and processes. Topics include human factors, occupational health and safety, dynamic and systems reliability modelling, maintenance optimisation, uncertainty analysis, resilience assessment, risk and crisis management.

Machine drives using closed-loop speed control are state of the art. As on drives without closed-loop speed control, the movement of a machine part at varying speeds frequently gives rise to a hazard against which the machine operators must be protected. The simplest means of preventing movements during manual intervention in danger zones is the (safe) disconnection of the energy driving the relevant motors. This is however often not possible, for example when intervention is required whilst the machine is running for the purpose of clearing faults, setup, during test operation, etc. Scenarios such as these require the machine to be operated with protective equipment disabled. In order for the operators‘ safety to be assured nonetheless, Annex I, Section 1.2.5 of the Machinery Directive sets out the required measures. Safety sub-functions for drive controls have been defined for implementation of the machine functions required for this purpose. Examples are STO (safe torque off), SLS (safely limited speed) and SS1 (safe stop 1). This report addresses the use of drive control equipment that implements safety sub-functions at a certain Performance Level according to ISO 13849-1 in consideration of the application and risks. The basic safety sub-functions of drive controls and the requirements relating to their use are presented. The principles of operation of frequency inverters and DC converters are described, and implementation of the safety sub-functions are explained. Examples are provided of application circuits by which the various machine safety functions can be implemented. The corresponding SISTEMA files for quantification of these safety functions are available for download free of charge. The examples include both standard frequency inverters and frequency inverters with integrated safety functions.
