CHAPTER 3
Project Reference
This chapter describes the different views available; the features common to the objects displayed in the Project
Window and standard Microsoft Windows procedures that are also common to these components.
Project Workspace
The project workspace displays the project as a hierarchical tree structure showing related
PLC and program details. Select the Toggle Project Workspace button from the toolbar to
display the project workspace and remove the project workspace from the display.
A description of each object in the Project Tree Workspace and their associated context sensitive menus is
provided in Chapter 4 - Reference.
Double clicking on an object opens it either in the Diagram Workspace or in a new window. Selecting an object
and clicking the right-mouse button displays the associated context sensitive menu.
The hierarchy can be collapsed or expanded to show either a partial view or full view of the
project tree.
More than one Ladder Diagram symbol table or Mnemonics View can be displayed. Select the appropriate
window from the list of open windows from the Window menu.
Program Sections
For the easier management of large programs, a program can be divided into a number of definable, named
sections. A section is like a chapter in a book – the PLC scans the sections in order.
A list of the sections in a program is displayed in the project workspace under the program name. There is also a
section list view showing the Start and End steps, which can be opened in the workspace window by clicking on
a program name.
It is possible to reorder and/or rename the sections from this list or from the project workspace. It is important to
remember however that when reordering or deleting sections, keep the ’END’ section at the end of the program.
Program sections can be reordered using the mouse to drag and drop sections up or down in the section list.
When using the keyboard, the 'Move Up' or 'Move Down' commands from the context menu of a section on the
project workspace are used.
Sections in a specific program can also be used to store frequently used algorithms that can then be copied to
other programs, using a section as a kind of library.
