Redundancy Page
The
Redundancy page in a junction’s
Properties window specifies redundancy information. The properties on this page are available only for a junction or end node that joins multiple connectors. The
Redundancy page is not shown in the
Properties window for the start node. It is also not shown if you open the
Properties window from an
RBD Style Library file. For more information, see
RBD Style Library Files.
The properties on the
Redundancy page for a junction are a subset of those on the
Redundancy page in the
Calculation Properties window for a block. For more information, see
Redundancy Page.
You can define the redundancy at the point where a junction joins connectors for the multiple blocks representing the redundant components. Or, you can define the redundancy in the Calculation Properties window for the single block representing all of the redundant components.
You define the redundancy in the junction’s Properties window only when you use a junction to connect non-identical redundant components. Otherwise, when redundant components are identical, you define the redundancy on the Redundancy page in the block’s Calculation Properties window.
Example
Suppose you have a parallel system consisting of three units where only two of these units are required for the system to operate. On the Redundancy page for the junction, you enter a value of 2 for Quantity required. If a junction is inserted to join a set of parallel units, for Quantity required, you enter a value of 1. This represents the number of connectors entering into that particular junction.
For load-sharing redundancy,
Load is available in the junction’s
Properties window. While you specify whether the load is shared by redundant components here, you specify the load relationship and the weight in the
Calculation Properties window for each redundant block. For more information, see
Load-Sharing Notes.
