Note 1: Error 1: More than one i_bS_ModeX=ON is selected at the same time.
Error 2: The i_bS_ModeX=OFF state remains for longer than i_dModeMonitorTime.
Note 2: The transition from any state to the Idle state due to i_bActivate=OFF is not shown. However these transitions have the highest priority (0).
