• The selective coupling point and parallel branch
point can be the same.
Note that in the Motion SFC chart, this type is
displayed in order of a selective coupling
a
parallel branch, as shown on the left.
• In this case, a pointer (Pn) cannot be set between
the selective coupling point (IFEm) and the parallel
branch point (PABm).

• Execution waits at the parallel coupling point and
shifts to the selective branch.

the parallel coupling point (PAEm) and the
selective branch point (IFBm).
