4.5.6 Deleting Connections
▶
Move the cursor onto the contact field or coil field to the right of the
connection that you want to delete. Press ALT to switch to Connect
mode.
▶
Press DEL.
The easy800 device deletes a connection branch. Closed adjacent
connections will be retained.
▶
Close the delete operation with ALT or by moving the cursor to a contact
or coil field.
4.5.7 Insert Rung
The circuit diagram display shows three of the 256 rungs at the same time.
Rungs outside of the display, including empty rungs, are scrolled by easy800
automatically in the circuit diagram display if you move the cursor beyond 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 rung.
▶
Press ALT.
The existing rung with all its additional connections is “shifted” downwards.
The cursor is then positioned directly in the new rung.

￫
In a rung, the easy800 device connects contacts and the
connection to the relay coil automatically if no empty fields are
between them.
