Function
After a selective branch, a parallel branch can be
performed.
IFT2
• The selective coupling point can be the same as the
coupling point of a parallel coupling for selective
branch  parallel branch. Note that in the Motion
SFC chart, this type is displayed in order of a
parallel coupling  a selective coupling, as shown
on the left.
• In this case, a pointer (Pn) cannot be set between
the parallel coupling point (PAEm) and the selective
coupling point (IFEm).
After a parallel branch, a selective branch can be
performed.
PAT2
• The parallel coupling point can be the same as the
coupling point of a selective coupling for parallel
branch  selective branch. Note that in the Motion
SFC chart, this type is displayed in order of a
selective coupling  a parallel coupling, as shown
on the left.
• In this case, a pointer (Pn) cannot be set between
the selective coupling point (IFEm) and the parallel
coupling point (PAEm).
After a selective branch, a selective branch can be
performed.
IFT2
• The two selective coupling points for selective
branch  selective branch can be the same. Note
that in the Motion SFC chart, this type is displayed
in order of a selective coupling  a selective
coupling, as shown on the left.
• In this case, a pointer (Pn) cannot be set between
the selective coupling point (IFEm+1) and the
selective coupling point (IFEm).
• After a parallel branch, a parallel branch can be
performed.
• A parallel branch can be nested up to four levels.
