  We report simulations of a frustrated odd-numbered macrospin ring system,
with full point dipolar interactions, driven by a rotating uniform applied
magnetic field of constant magnitude. The system is designed with
equally-spaced radially-aligned macrospins, which must carry a frustrated
soliton defect in its ground state. It is shown how correctly tuning the
applied field magnitude can allow for non-trivial unidirectional propagation of
the soliton, the required directional pressure acquired via the curvature of
the ring. Furthermore, the system, which may be employed as a multiple rotation
counter, is tested for robustness against quenched disorder as would be present
in an experimental realization.
