Activating step 4
Step flag M0.4 is set if the sequencer is at
step 3 (M0.3 ="1") AND input I0.4 (initial
position) becomes "1". At the same time,
M0.3 is reset.
Activating step 5
Step flag M0.5 is set if the sequencer is at
step 4 (M0.4 = "1") AND timer T38 has
elapsed. At the same time, step flag M0.4
is reset.

Activating step 0
If step flag M0.5 is active (overshoot time
T38 is finished), step 0 (initialization step)
is activated from the sequencer. This step
in Network 6 has been included
deliberately so that further conditions such
as removal of the work piece could be
scanned at this point before re-activation of
step 0.
This condition would then have to be
switched in parallel to contact M0.5.
