• 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.
