ITEM TOOLKIT

Chapter 3 ToolKit Basics 85
The System Window
Located in the lower left corner (default location); the system windows shows the hierarchy of the system components
included in the system selected in the Project window. Cross tabs located on the edge of this window indicate the type of
analysis module that is active in bold (A) along with other recently used analysis modules. The following items and their
icons are shown in the System window hierarchy tree when using the prediction and FMECA modules. RBD, Markov,
Event Tree and Fault Tree use additional items and icons in the hierarchy tree due to the different nature of the systems.
System Header: Shown with a multiple pockets file folder icon - Listing includes system information and
sum of reliability data for the total system.
System Block: Shown with a single file folder icon – Listing includes sum of reliability data for all blocks
and components attached to this block.
Linked Block: Shown with a single open file folder icon with a green arrow pointing to it – This is a special
block that is a mirror image or direct copy of another block and its attached components. The Linked Block
automatically updates when data is changed for the block to which it is linked. The Linked Block displays
the same data as standard system Block (Used with reliability prediction modules only).
Component: Shown with a blue box icon – Listing indicates a single component and its data (lowest level of
the hierarchy tree in the prediction systems).
Library System Window
FMECA Component: When using a FMECA system, the component blue box icon becomes a
blue file folder icon.
FMECA Failure Mode: Shown with a red box icon - Indicates a failure mode (only used with the
FMECA systems).
The Library System window is located in the middle of the workspace (default location). This system window stores a
library of frequently used systems, blocks and components that helps save time and effort in constructing future systems.
The user can create their own custom libraries of components, blocks and even entire systems for later use in future
projects. Item Software also has several application specific libraries available that contain thousands of components and
their reliability data. The convention for icons and line items listed in the Library System window are the same as the
regular System window discussed above.
