Comprehensive description of safety-relevant electronic systems
Safety-related electronic systems are more and more employed into almost all ranges of technology. New regulative measures of the legislator, which are to guarantee the safety, security and integrity of persons and goods, lead to an increasing necessity for such systems in complex control and automation systems of all industrial branches.

One of the most important standards for the proof of the appropriate safety level is the international standard EN IEC 61508. During the formulation it was attended to make no determination which will prevent the employment of future, not yet known technologies. Rather the requirements in the standard are formulated on the highest possible abstraction level. Therefore, the EN IEC 61508 is not to be understood so easily.

With this book the reader obtains a comprehensive and understandable standard work, with which the development and integration of safety-relevant electronic systems are made possible for him.

Covered are, e.g.:
- Fundamental requirements of the safety engineering
- Risk and requirement classes
- Development of safe hardware
- Development models for software
- Error prevention and revelation
- Reliability, availability and failure rates
- Risk disclosure of technical systems
- Probability of distribution
- Sample applications for safety computer architectures
- Circuit measures
- PFD computation up to the most modern architectures 2oo4 and 2oo4D
- Computation of MTTF values by Markov-Models and Monte-Carlo-Simulation.
