The method and apparatus of the safe parameterization of four from EN954-1 Category 1 or 3 from IEC61508SIL1

摘要

The invention relates to a method and an apparatus for safe parameterization in accordance with IEC 61508 SIL 1 to 3 or EN 954-1 Categories 1 to 4 of safe electronic appliances. One object of the invention is to describe a way which overcomes the explicit reading back of the parameters from the safe electronic appliance and confirmation of each of these parameters by the user. For this purpose, the invention proposes that parameter values which are intended for parameterization, are selected or entered via a user interface of an electronic control device and are then transmitted to the electronic appliance, to be kept in at least one memory which can be accessed by the control device, and be read back at least once from the memory for verification of the safe parameterization.
