Starting a New Project
Once the project requirements have been worked out on paper, the first step is to create a project and define the
device entries for that project. A project can have multiple PLCs. CS/CJ/CP-series PLCs are multi-tasking and
can therefore have more than one program associated with them in the project; CV-series PLCs and C-series
PLCs can only have one program associated with the device.
Note: To create a new project using only SFC or ST, use CX-Programmer Ver. 7.2 or higher. Select
Tools – Options and set the Default Program Type in new PLC : on the PLCs Tab Page to SFC
or ST to create an SFC or ST program from the beginning, instead of a ladder program.
Use the following procedure to create a new project.
1, 2, 3… 1. Select the New button from the toolbar.
2. Define the device entries for the project. Refer to the CX-Server PLC Tools User Manual
for further information. For this tutorial, set the PLC type as CS1H with CPU type
CPU67.
3. Save the project. Select the Save Project button from the toolbar. The Save CX-
Programmer File dialog is displayed.
4. Type a valid file name in the File Name field. Select the Save pushbutton to save the new
project. Select the Cancel pushbutton to abort the operation.
When a new PLC is added to a project, the following empty tables are created:
♦
Empty local symbol table;
♦
Global symbol table containing pre-set symbols;
♦ IO Table;
♦
PLC Memory data;
♦
PLC Settings data.
The project workspace is populated with the contents of the newly created project and a Ladder program is
displayed in the Diagram Workspace ready for programming to begin.
A description of each object in the project hierarchy is provided in Chapter 4 - Reference .
Within the Ladder program, the current position is indicated by a highlighted rectangular block, known as the
cursor. Using the mouse or the arrow keys, the cursor can be positioned at any point within the diagram. An
element can be placed at the current cursor position by either selecting it from the
Insert menu, selecting it from
the toolbar or by pressing its assigned shortcut key. An element can be placed in any empty grid position, or
may overwrite a horizontal element.
