Parallel coupling
• The two parallel coupling points for parallel branch
parallel branch can be the same. Note that in the
Motion SFC chart, this type is displayed in order of
a parallel coupling a parallel coupling, as shown
on the left.
• In this case, a pointer (Pn) cannot be set between
the parallel coupling point (PAEm+1) and the
parallel coupling point (PAEm).
Selective coupling

Parallel branch
• 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).

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