Possible Data Links
The following table describes items that can be linked to other items in the System file and indicates the one or more properties that is brought over from these links. For more information, see:
Module
Item
Possible Links
Data Source
Data Brought Over
Event Tree
Branch or column
A FMEA Worksheet item or mode
FMEA
FMEA item or mode failure rate
An FTA gate or event
FTA
Gate or event failure rate
An assembly or part in a particular system tree configuration
Prediction
Prediction failure rate
FMEA
Item in the FMEA tree
A FMEA Worksheet item or mode for a FMEA tree item in a different FMEA
FMEA
FMEA item or mode failure rate
An assembly or part in a particular system tree configuration
Prediction
Prediction failure rate
* 
In a component FMEA, the items in the FMEA tree are linked to the items in the system tree so that their prediction failure rates are used. You do not need to take any action to set up these links, which cannot be removed.
FTA
Event
A FMEA Worksheet item, mode, or effect
FMEA
FMEA item, mode, or effect failure rate
A diagram in the Markov Table
Markov
Markov diagram failure rate
An assembly or part in a particular system tree configuration
Prediction
Prediction failure rate
LCC
Alternative
A block diagram in the RBD Table
RBD
RBD data fields used in LCC equations
An assembly or part in a particular system tree configuration
Prediction
Prediction data fields used in LCC equations
* 
In the LCC module, data links are specified in a different manner. The system tree item or RBD to use in equations for various design alternatives are specified on the Link to System Tree Items page and Link to Block Diagram page under LCC in the Calculate window. For more information, see LCC Calculation Properties.
