Tool Tips

* What does the asterisk on the Plot Setup Titles page in RENO and Weibull++ 7 mean?
Both Weibull++ 7 and RENO use an asterisk (*) to represent the default title for each field, defined in the Set Default Plot Titles window.

If you type new text in an input box, either instead of or in addition to the asterisk, the text you type will be displayed on the plot. For example, if you add (Part A) to the Main Title field, the default main title will be displayed, followed by "(Part A)." The changes you make will be applied regardless of plot type, so the main title of a Reliability vs. Time plot would then be "Reliability vs. Time (Part A)" and the main title of a pdf plot would be "Probability Density Function (Part A)." (This assumes that you have not changed the default main titles from the ones shipped with the application.)

* Can a single block or component be used more than once in a Lambda Predict project?
You can create linked blocks in any system within the same Lambda Predict project. These blocks represent the relevant standards based reliability prediction characteristics of another block or component. If you change the characteristics of the source block or component, they will be reflected automatically in the linked block. The linked block and the source block/component can be in different systems, but must be within the same project.

To add a linked block to a system, select Add Linked Block from the System menu or select Add and then Add Linked Block from the System Panel shortcut menu. Next, right-click the linked block and select Start Selection for Source from the shortcut menu. The cursor will change to < - >, which indicates that the application is in link mode. Right-click the block or component that will be the source for the linked block and select End Selection for Source from the shortcut menu. (If you want to cancel linking the blocks, select Cancel Link from the shortcut menu.)

Once you have linked the block, you can select it and click the Physical tab in the Dialog view of the Data panel. The name, source name and failure rate of the source block/component will be displayed, as shown next.

This indicates that the relevant standards based reliability prediction characteristics from the source block/component have been applied automatically to the linked block. You can update the text parameters for all linked blocks in the current project to match the text parameters of the source items by selecting Global Update Linked Text from the Tools menu.

You can view the link information for a block or component in the Link Info window. To open this window, select a linked block or source block in the System panel and then select View Intra Project Link Data from the System Panel shortcut menu. The Link Info windows for a linked block and a source block are shown next.


You can also use the Project Link View window to view a summary of all the links that have been established within the current project. To open this window, select a project from the Project panel and then select Project Link View from the Tools menu. The window will appear, as shown next.

Tabs will appear at the bottom of the window, which allow you to view the links for the current project and for each system within the project. Click a tab to view the links for the individual system.
