| Abstract: | A method of generating safety critical data in line with EN50128-2011 is introduced,which includes two processes: the development of data generation tools and the generation of safety critical data.The method of double-chain tools are adopted as the tools of data generation which are developed by two independent teams and the development of each chain tool confirms to the requirements of EN50128-2011 SIL2 software.The process of data generation defines the activities like generation,verification and validation and personnel independence of each activity is ensured as well.Thus,safety problems can be avoided and the generation efficiency of configuration data can also be improved greatly. |
