Over the next ten years picture a safety circuit with six safety certified components and four are certified to Performance Level (PLx) and the other two are certified to Cat.x! Is the outcome clear? True, the European Machinery Directive has ruled that EN 954-1; 1996 will be fully replaced in December, 2011 by EN/ISO 13849-1; 2008.

This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions.

EN ISO13849-1 uses an interactive process for the design of the safety-related parts of control systems, as follows: • A required performance level “PLr” (target value) must be specified for each intended safety function. • The safety function requirements are derived from the necessary risk reduction. A free EN ISO 13849-1 Performance Level Calculator is available from the IFA (Institut fuer Arbeitsschutz der Deutschen Gesetzlichen Unfallversicherung) in Germany. This simple tool, developed in conjunction with the German ZVEI and VDMA organisations, consists of two discs; rotating the bottom disc reveals different values through windows cut in the top disc.

A partir de 2012, se encuentra en vigor, únicamente, la versión EN ISO 13849-1:2008 (adoptada como norma nacional UNE­ EN ISO 13849-1:2008). La parte 1 de esta norma fue completada con una segunda parte EN ISO 13849-2:2003 “Seguridad de las máquinas. Partes de los sistemas de mando relativas a Performance Levels (PL) Die Sicherheitsfunktion beziehungsweise der erreichte Performance Level (PL) ist auf den in der Risikobeurteilung bestimmten erforderlichen Performance Level (PLr) zu überprüfen.

Vi kan ge stöd för både Performance level enligt EN13849-1 samt SIL enligt SS-EN 62061, EN61511 / EN61508. Zert kan erbjuda ett stort antal 

EN ISO 13849-1 goes beyond the qualitative approach of EN 954-1 to include a quantitative assessment of the safety functions. A performance level (PL) is used for this, building upon the categories. This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software.

The hazardous situation is classified into five   This article focuses on the calculation of performance level (PL) by standard ISO 13849-1 Safety of machinery – Safety- related parts of control systems – Part 1:  This is replaced by new standards with Performance Level, PL (EN ISO 13849-1) and Safety Integrity Level, SIL (EN 62061). These two new standards define  Work through the eight-step design process of ISO 13849-1 Evaluate the Performance Level (PL) of each Safety Function. 5. 6.

Image credit: TUV Once the performance level has been determined, the architecture that facilitates the defined performance level is classified into one of six categories (“B” and 1 thru 5, with B being the least safe and 5 being the most safe). This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level required for carrying out safety functions. an appropriate PLr (Performance Level required) for each identified safety function. A central part of EN ISO 13849-1:2008 is to choose an appropriate category for the identified safety functions.

• PL (Performance Level) is a technology-neutral concept that can be used for electrical, mechanical, pneumatic and hydraulic safety solutions. • SIL (Safety Integrity Level) can, however, only be used for electrical, electronic or programmable safety solutions. Experience EN ISO 13849-1 uses categories from EN 954-1 for defining the system Performance Levels are only referenced in one standard, ISO 13849. Safety Integrity Levels are referenced in IEC 61508 and all the other standards derived from it.

SIL level up to SIL 3 according to EN IEC 62061, Performance Level (PL) up to PL e according to EN ISO 13849-1and safety category up to category 4 according  ISO 13849-1 Safety Category. Cat. 4.
