Functions are FMEA records that state what the item or process is intended to do, usually to a given standard of performance or requirement.
The following topics are discussed here:
Tip: You can specify for a default function to be created for all new items added to the System panel by choosing File > Application Setup and selecting the Create Default Function for New Items option on the Settings page of the Application Setup.
To add or insert functions into an FMEA, choose FMEA > FMEA Records > Functions, then select one of the following options:
Add Function adds a new record to the bottom of the list.
Insert Function inserts a new function above the one that is currently selected.
Import Functions opens the Import Existing Functions window so you can choose to copy one or more existing functions into this FMEA. There is no link to the original record(s) (i.e., changes made in one record will not automatically update the other(s)), and you have the choice to import with or without dependents (e.g., associated failures, effects, causes, etc.).
To edit an existing function in the FMEA, either edit it directly in the worksheet view or use the properties window. To open the properties window, select the function and choose FMEA > FMEA Records > Functions > Edit Function or double-click the function in the hierarchy or filtered view.
If you have copied a function, there are two options when you choose Home > Clipboard > Paste:
Paste (CTRL+V) pastes the function(s) and all dependent records (e.g., associated failures, effects, causes, etc.).
Paste Without Dependents pastes only the function(s) without any dependent records.
The properties enabled (and their display names) will depend on the interface style for the current project. To view or change these settings, choose Project Management > Configurable Settings > Interface Style.
Note the following:
The Function Description is required.
The Short Description is a shortened version of the record description that will be used in locations where the full description would be too long to display (e.g., diagrams). If the field is blank when you save the record, the application automatically populates it based on the first 50 characters of the full description.
Tip: If you need to define the reliability characteristics for this record, use the FMRA tab. These characteristics will be applicable if you wish to perform criticality analysis, use the FMEA occurrence ratings to calculate a preliminary baseline estimate of the system reliabilityor share system configuration/reliability data between Xfmea and BlockSim.
