Description
|
The description of the event tree column.
|
Code
|
The unique code assigned to the event. For more information, see Codes. This field is unavailable for the initiating event, which is the event that begins all possible event sequences in the event tree. All other events are assigned a code so that results for event sequences (branches) can be shown in the Event Tree Results table.
|
Parameter definition
|
Indicates the source of the calculation data for the column. Choices are:
• User defined. When selected, the properties under Input type become available so that you can specify the data to use for calculations.
• Event parameter. When selected, an event parameter can be selected in the field to the right. This property is unavailable if no FTA Event Library files are enabled.
• Linked to assembly, Part, FMEA, or FTA data. When selected, the column is linked to another item in the System file. In this case, all other properties are unavailable because calculation data for the column is obtained from the linked item.
|
Input type
|
The type of calculation data available for the event. This property is available only if User defined is selected as the parameter definition. Choices available are the same as the model selections available for a user defined event in a time dependent tree. For descriptions, see Time Dependent Event Properties.
