3.3.4 Changing Ladder Programs
This subsection describes how to modify ladder programs.
NOTE
1 To modify a ladder program, copy ladders from the
display window to the edit window. Then, change
them on the display window and substitute the
ladders on the display window with those modified
on the edit window.
2 If there is a ladder error in the ladders on the edit
window, it is impossible to select the <Insert> and
<Replace> buttons.
3 Double-clicking a ladder on the display window
causes the ladders in the same net as the clicked
ladder to be copied to the edit window.
Procedure
1 On the display window, position the cursor to the ladder you
want to modify, using the cursor control keys.
