Initiating Event Records

Initiating Event records are used to determine the frequency of occurrence of an initiating event. This topic provides an alphabetical list and description of the fields that exist for the Initiating Event family and appear on the LOPA datasheet. The information in the table reflects the baseline state and behavior of these fields.

This family is not enabled for site filtering, which means that records in this family can be accessed by any user with the appropriate license and family privileges. See the Site Filtering section of the documentation for more information.
