5. SEQUENCE PROGRAMS AND SFC PROGRAMS
5 − 18
POINT
(1) When an [SV] step is created, the servo program start request ladder
block
SVST
***
is mandatorily inserted in the sequence
program.
(2) If an SVST instruction is edited and converted, a start accept bit (M2001
to M2032) is automatically inserted into the switching conditions before
and after the relevant SFC step to act as an interlock.
However, if the order of steps has been changed by addition or insertion,
this interlock may not be automatically added/deleted in the switching
conditions. Therefore, if a step has been added or inserted, always
display the switching conditions using ZOOM display and check the
interlock.
(3) Only the sequence
SVST
***
can be set at an [SV] step.
If any additional instructions are to be set, either set them in a normal
step (") or set another sequence instruction section executed in parallel
as a normal step (").
(4) For details on how to operate peripheral devices used to edit and monitor
SFC programs, refer to the SW2SRX-GSV13PE Operating Manual and
SW2SRX-GSV22PE Operating Manual.
