The workspace area is shared with a cross-reference window and a code view
window in which the structured text equivalent of the ladder diagram can be
viewed. The Show Cross Reference tool (see subsequent paragraphs describing
the editor tools) activates the cross-reference window. Dragging the splitter bar
on the left side of the editor workspace to the right reveals the code view
window. This is a view-only window – structured text cannot be edited.
Each ladder diagram has a set of properties: diagram name, type, and description.
The name is limited to 30 characters (like Flow Charts) and will default to LadderX
where X will be the next sequential index of all ladder diagrams for the project.
The type can be either program (the default) or sub-ladder, allowing it to be
called like a subroutine from another ladder diagram. The optional description
can be text of essentially unlimited length describing the overall operation or
purpose of the diagram. These properties can be defined when the diagram is
first created or later, using the Program Properties dialog. This dialog is activated
by a right click anywhere within the workspace (to activate a context menu) and
selection of the Edit Program Properties entry. The dialog appears as:
Once the program properties are as desired select the OK button to save the
values or select Cancel to leave the properties unchanged.
The Ladder Diagram toolbar
Access the Ladder Diagram programming tools from this bar. The toolbar allows
you to select blocks, place a variety of block types, change zoom levels and special
viewing mode, hide/show block labels, and check diagram integrity. To select a
tool, simply click its button.
