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. Therefore, the Category system is being replaced by the Performance Level system of hazard determination and mitigation.

Assigning category and performance level to a safety related system is somewhat complicated in ISO 13849. The following parameters play vital roles: MTTF d per channel; This means "Mean Time to Dangerous Failure" for one channel. Unlike IEC 61508, ISO 13849 is focused rather on channels than on complete safety related systems.

The topic of EN 13849-1, introduced on October 2006, is the reliability of safety The evaluation of the performance level is based on the ability of the safety The value of PL can be derived from the MTTFd or the B10d, respectivel

• 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 We received an order to develop a customized solution to act as a signal interface between analog signals to CAN-bus.

ISO 13849-2, Part 2: Validation, specifies the procedures to be followed for validating by analysis or tests, the safety functions of the system, the category achieved and the performance level achieved. In Part 1, ISO 13849, the design of the safety system is based on the risk assessment performed by the manufacturer of the machine. The EN ISO 13849 series of standards describes simple methods for evaluating safety-related control systems. The PLC disc supports you in estimating the probability of dangerous failure as described in the standard. How is the disc used?
