Inserting and deleting a rung

The CL circuit diagram shows four of the 128 rungs in the
display at the same time. The logic relay automatically scrolls
up or down the display to show hidden rungs – even empty
ones – if you move the cursor past the top or bottom of the
display.
A new rung is added below the last connection or inserted
above the cursor position:
Position the cursor on the first contact field of a circuit
X
connection.
Press ALT.
X
The existing rung with all its additional connections is
"shifted" downwards. The cursor is then positioned directly
in the new rung.
Deleting a rung
The logic relay only removes empty rungs (without contacts
or coils).
Delete all the contacts and relay coils from the rung.
X
Position the cursor on the first contact field of the empty
X
rung.
Press DEL.
X
The subsequent rung(s) will be "pulled up" and any existing
links between rungs will be retained.

Switching with the cursor buttons

The logic relay also allows you to use the four cursor buttons
as hardwired inputs in the circuit diagram.
The buttons are wired in the circuit diagram as contacts P1

to P4. The P buttons can be activated and deactivated in the
system menu.
