Program steps (graphically represented) are entered in a row or ladder ‘rung’ between the left (power supply)
and right (output) bus-bars.
Additional rows and columns can be inserted into the Ladder program via the Insert Row option and Insert
Column option from the context sensitive menu. Rows and columns can also be removed by selecting Delete
Row option and Delete Column option from the context sensitive menu.
By inserting Vertical Up or Vertical Down, rungs cannot be combined into one. To do this, select the rungs to be
combined and select
Combine from the context sensitive menu. When a rung needs to be divided, select Split
from the context sensitive menu to divide the rung into two.
Allowing ladder screen display only, and prohibiting program editing while offline is possible (CX-Programmer
Ver. 4.0 or later). Select
Read Only Mode from the Edit Menu to enable this function.
After temporary editing of a specific rung (in temporary memory), the user can select to utilize (store) or delete
(cancel) the editing results (CX-Programmer Ver. 4.0 or later). Select
Read Only Mode – Start Edit from the
Edit Menu, and then perform either of the following steps after editing.
a) To apply the editing results, select Read Only Mode – Store from the Edit Menu. The edited contents will
be reflected in the program.
b) To not apply the editing results, select Read Only Mode – Cancel from the Edit Menu. The edited contents
will be deleted. Therefore, after editing rungs and writing and recording temporary changes, the user can
select to either apply or delete changes, enhancing program editing efficiency. (This function is similar to
the SYSMAC Support Software store function.)
Inserting a Program
A program is set up when the project is initially configured. For CS/CJ/CP-series PLCs and CV-series PLCs, it
is possible to add multiple programs.
Use the following procedure to insert a program.
1, 2, 3… 1. To insert a new program, select the PLC object in the project workspace.
2. From the Insert menu select the Program - Ladder, Structured Text or SFC option.
An empty Ladder, ST or SFC program is placed in the Diagram Workspace.
3. The task type associated with the program must be assigned (not for C-Series PLCs).
Select the program object in the project workspace and select the Show Properties button
from the toolbar. The Program Properties dialog is displayed.
4. From the General tab, select an option from the Task Type field.
5. Select
the Close button from the title bar to close the Program Properties dialog.
The project is updated, showing a new program inserted at the bottom of the hierarchy together with an empty
local symbol table. Task types available are as follows (the icon is displayed next to the Program object in the
project workspace, and the task number is shown in brackets to the right).
Task Type Icon Task Type Icon

Contact and Coil Editing
The Edit Contact dialog or Edit Coil dialog allows the name or address of the contact or coil to be entered or
selected from a list of global and local symbols. The name or address can also be defined as a new symbol from
this dialog and inserted into the local or global symbol table.
The dialog can be displayed in two forms, either: simple dialog mode or detailed dialog mode . The default
mode can be set in the Diagram tab in the Options dialog. To change the simple dialog mode to a detailed
dialog mode , select Detail pushbutton.
