SIF Common Cause Failure Records

SIF Common Cause Failure records store details about a failure or a condition within a plant that can affect the operation of multiple instrumented functions (i.e., common cause failures). This topic provides an alphabetical list and description of the fields that exist for the SIF Common Cause Failure family and appear on the SIF Common Cause Failures datasheet. The information in the table reflects the baseline state and behavior of these fields.

This family is enabled for site filtering, which means that records in this family can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.

Field	Data Type	Description	Behavior and Usage
CCF Description	Text	The description of the common cause failure.	This field is required. On the SIF Common Cause Failure datasheet, you can select the button to define this value manually via the CCF Description dialog box.
CCF ID	Character	The ID for the common cause failure.	This field is required. On the Common Cause Failures tab on the <Record ID> (Instrumented Function) window, this value appears as a hyperlink that you can select to access the contents of the corresponding SIF Common Cause Failure in a new window.
CCF Mitigation	Text	A brief description of ways to mitigate the effect of the common cause failure.	This field is required. On the SIF Common Cause Failure datasheet, you can select the button to define this value manually via the CCF Mitigation window.
