Abstract :
In order to obtain a safety electronic system of control, in general it will be necessary to assign a redundancy approach. Nevertheless this makes the equipments more expensive. Throughout this paper, a method based on dynamic logic is set out in order to achieve safety systems with programmable logic controllers
