Enabling and Viewing the FMRA

In both Xfmea/RCM++/RBI and BlockSim, you can use the Show FMRA command in the View tab of the ribbon to enable or disable the feature for your computer. (You can set this separately for each application.)

To view the FMRA once it is enabled:

• In Xfmea/RCM++/RBI, go to the FMRA tab in the System panel.

• In BlockSim, go to the FMRA tab of the current project explorer.

FMRA Columns

To hide or display columns in the FMRA, or change the column order, right-click the column headings and choose Customize Columns. (You can also change the column order by dragging and dropping column headings into the desired positions.) These preferences are set separately for each application, and they are stored per computer/username.

• Name displays the record description/name. This column cannot be hidden.

• User Access displays a status indicator when the record is in use ( ), when you don’t have permission to edit ( ) or when the record is locked by an FMEA change log ( ).

• Record Type indicates whether the record is an item from the system hierarchy, or a function, failure or cause from an FMEA.

• Synchronized with BlockSim displays if the record is being synchronized with an FMRA diagram in BlockSim. (See FMRA Diagrams and Reliability-Wise Configurations.)

• Reliability Policy displays one of the following. (See Setting the Reliability Policies.)

• • Inherit indicates that the record's reliability/maintainability will be determined by its dependent records.

  • Default (Not Set) indicates that the record is set to "Define at this level" but does not yet have an assigned URD. The software will assume that the reliability is 100%.

  • The name of the universal reliability definition (URD) that is assigned to the record.

• Mirror Group displays the name of the mirror group that a cause belongs to, if any. All the causes in a mirror group are treated as the exact same event. (See Using Mirror Groups in an FMRA.)

The remaining columns pertain to FMRA results, which are discussed in Analytical Results in an FMRA and Simulation Results in an FMRA.
