Deleting elements

Selected elements may be deleted using the Delete tool. Object
deletion is also possible using the Edit menu or the keyboard DEL key.
Be advised that element deletion is not undoable. Unlike cutting an
element, the Delete action does not place a copy of the element in the

clipboard.

5.8.6 Adding comments to a Ladder Diagram

Ladder Diagrams may be given optional comments or captions as an aid in
documenting the logic flow.

Program Properties

Program properties include the Program Name (as it appears in the Project
Workspace pane), the Program Description, and the

Sub-Ladder

option. To edit

these properties, right-click anywhere in the Ladder Diagram and choose Edit
Program Properties
from the context menu.

Rung Properties

Rung properties include the Rung Label and Rung Comment. To edit these
properties, right-click on the desired rung and choose Edit Rung Properties
from the context menu.

The visibility of rung comments may be toggled using the Show Rung
Comments
tool in the Ladder Diagram

toolbar

. Rung comments are visible

by default whenever the ladder editor is started.

Block Captions

Each function block in a Ladder Diagram can have its own Block Caption. To edit
a block’s caption, right-click on the desired block and choose Edit Block Caption
from the context menu.

The visibility of block captions may be toggled using the Show Captions
tool in the Ladder Diagram toolbar. Rung comments are visible by default

whenever the ladder editor is started.

NOTE: Rung logic (the contacts, coils and function blocks comprising the
ladder diagram) may be shown or hidden using the Show Rung Logic tool.

Rung logic is visible by default whenever the ladder editor is started. This feature
may be useful when comments are defined for each ladder rung. By hiding the
rung logic, leaving just the comments visible, a text only description of the ladder
diagram will be seen, allowing the viewer a quick overview of the purpose and
functionality of the ladder diagram.
