Basic Editing ─ Creating a Contact and a Coil 
(1)  Click    on the toolbar, and then move the mouse cursor to the red frame in Network 1. The mouse 
cursor changes to a contact when the mouse cursor is moved to the left, right, or bottom of the red frame. 
Decide where to insert a contact. If you edit a ladder diagram, the mouse cursor must be near a position 
you want to edit. The system automatically arranges an inserted object; you cannot move the object. 
In this example, you do not need to decide where to insert the contact. Place the mouse cursor near the 
red frame and click the left mouse button.
