Safety Integrity Level Records

Safety Integrity Level records are used to determine the SIL value and contain the boundary values for the required probability of failures for different safety integrity levels. This topic provides an alphabetical list and description of the fields that exist for the Safety Integrity Level family. The information in the table reflects the baseline state and behavior of these fields. This list is not comprehensive.
