Showing an Input Tree

You can visualize the "input tree" for a block by selecting Show Input Tree For This Block from the Function Block popup menu (i.e. right-click on a Function Block). The Function Block which is the root of the tree is outlined in red, and its inputs are highlighted in red. Subsequent layers in the tree are outlined and highlighted in darker red.

Viewing an Input Tree Across Multiple Sheets

If the input tree terminates at an input reference, it will continue from an associated output reference on another CAD/CLD diagram. You can navigate to this other sheet by going to the source of the input reference and continue to follow the visually highlighted lines of the input tree.

For example, this screenshot shows the input tree for a block. The tree terminates at two input references. Going to the associated output reference for the top one brings us to the CAD sheet in the second screenshot.

You can always return to the root of the input tree on the original document by right-clicking on any line in the tree and choosing Go To Input Tree Root from the context menu that appears.
