• 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).
