Practical Approach for the Evaluation of Safety Related Programmable Electronics

  • Conference paper
Safe Comp 95

Abstract

At the same time as microprocessor-based systems spread to all consumption devices, the safety related parts of control systems contain more and more often programmable electronics (PE). The control systems of railways, lifts, cranes, or generally process or machine automation, are examples of the application areas. A common feature for systems in these areas is that a failure in the safety related part of a control system can lead into hazard, dangerous situation, accident or even loss of life, if the system is not designed safe enough. Therefore a high level of reliability and safety is required for the PE1 to be accepted for use in this kind of safety related applications.
