Wiring with the display system

If several rungs are connected to one another, the display
system first deletes the vertical connection. If you press DEL
again, it will delete the horizontal connection as well.
Close the delete operation with ALT or by moving the cursor
to a contact or coil field.
Inserting and deleting a rung
The display system circuit diagram shows three of the
256 rungs in the display at the same time. If you move the
cursor past the top or bottom of the display, the display
system automatically scrolls up or down the display to show
hidden rungs – even empty ones.
A new rung is added below the last connection or inserted
above the cursor position:
X Position the cursor on the first contact field of a rung.
X Press ALT.
The existing rung with all its additional connections is
“shifted” downwards. The cursor is then positioned directly
in the new rung.

You cannot delete connections that the display system has
created automatically.
