4 MOTION SFC PROGRAMS
Combining the basic type branches/couplings provides the following application types,
which are defined as in the basic types.

performed.

• 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).
