Select the desired block (off-delay, see next diagram), and press the OK
key:
R
The inserted block receives the block num-
ber B02. Block B01, which has been con-
nected up to now to Q1, is connected auto-
matically to the uppermost input of the in-
serted block. The cursor is positioned at the
uppermost input of the inserted block.
B01
T
Q1
B02
The off-delay block has 3 inputs. The uppermost input is the trigger input
(Trg). You use this input to start the off-delay. In our example, the off-
delay is started by the OR block B01. You reset the time and output by
means of the reset input, and you set the time for the off-delay at T. You
reset the time and output by means of the reset input, and you set the time
for the off-delay by means of T parameter.
In our example, we do not use the reset input of the off-delay. We wire it
with ’x’. You learned how to do this in the first program, but just to re-
mind you, here is the procedure again:
1. Position the cursor under the R: or
2. Switch to input mode: OK
3. Select the Co list: or
4. Accept the Co list: OK
5. Select ’x’: or
6. Accept ’x’: OK
The display should now look like this:
x
B01
T
Q1
B02
Now enter the time T for the off-delay:
1. If the cursor is not yet under the T,
move it there: or
2. Switch to input mode: OK
