Deleting block groups

Let us assume you want to delete the blocks B1 and B2 from the following circuit program
(corresponds with the circuit program in the "Second circuit program (Page 83)" topic.
Proceed as follows:
1. Switch LOGO! to programming mode
(as a reminder, refer to the topic "The four golden rules for operating LOGO! (Page 66)").
2. To select 'Edit': Press
3. To confirm 'Edit': Press OK
(If required, enter your password and confirm with OK.)
4. To select 'Edit Prg': Press
5. To confirm 'Edit Prg': Press OK
6. To move the cursor to the input of Q1; that is, to B2, press
7. Confirm with OK.
8. Now set the connector 'x' at output Q1 instead of block B2. To do so:
– Select the Colist: Press
– Accept the Co list: Press OK
– Select 'x': Press
– Apply 'x': Press OK
Result: LOGO! deletes block B2 because it is no longer used in the circuit. LOGO! also
deletes all blocks that connect to B2, in this case, block B1.
